Cosmos-class Launch Commander, Odyssey-class Launch Platform

Postby The Selkie » Thu Dec 15, 2016 6:45 am

Technical Data – Odyssey-class Sea Launch Platform
Type: Semi-submersible mobile launch platform
Gross-Tonnage: 120,000 BRZ
Length: 198 m
Beam: 87 m
Draught: max. 27.5 m
Propulsion: IEP, 45,000 kW total
Speed: 10 knots
Crew: 70
Equipment:
    Blast deflectors, DGPS, hangar for rockets,
    Remote launch controls via Laige Network, crane,
    2 dinghies
Aviation facilities:
    Helicopter flight deck with
    outdoor maintenance facilities
The Odyssey-class Sea Launch Platform is the first component of the package, the mobile, semi-submersible launch platform at sea. It is a rather bare-bones design, based on a design for a semi-submersible oil rig from the 90s, capable of being remote-controlled via the Laige Network (see below).
The core and pride of the design is the capability to lift and place rockets, at sea, from the assembly bay on the Cosmos-class Sea Launch Commander onto the Rocket Deck thanks to a crane capable of lifting 7000 tons at once over a distance of 140 metres, capable of rotating 360 degrees. This crane also ensures, that the Odyssey-class Sea Launch Platform can be used for different purposes as well, for example as a Deepwater Construction Vessel. For storage and last checks of the rockets in question, a hangar is erected on the deck, accessible for the rocket with the help of a launch vehicle.
Once the rocket is loaded onto the platform and the ideal position for the launch reached, the ballast tanks are filled with up to 84,000 m³ of water rushing into the forty tanks, while, for a quicker fixation on one position, 14 additional tanks can be filled with up to 26,000 m³ of water. This increases the draught during normal transfer's 10.5 metres to 27.5 metres, which makes the vessel stand calmly even in rough sea.
Moved by ten propellers in gondolas, all capable of being controlled individually with highest precision, the Odyssey-class Sea Launch Platform can move at a speed of ten knots. They are diesel-electrical in nature, the power provided by the diesel engines also used to power the other systems of the vessel.
The Odyssey-class Sea Launch Platform is equipped with a Differential Global Positioning System and a system for dynamic positioning, which allows for holding position with utmost precision, either automatically or controlled by hand, while the responsible computer systems are double redundant. This works either with help of the sixteen anchors or without.
Before ignition of the rocket, the blast shields are raised and the whole vessel vacated by the crew for security reasons, all functions can be taken over by the Cosmos-class Sea Launch Commander via Laige Network. The blast shields protect the superstructure of the platform and redirect the launch fire of the rocket into the sea, behind the vessel, akin to a fire trench on dry shore.
Once the rocket is launched, the crew can go back onto the vessel and prepare it for the next launch. This can be achieved by either helicopter, a flight deck with outdoor maintenance facilities is installed on the rocket hangar, or via dinghies, two of which will be provided.
The Odyssey-class Sea Launch Platform carries the provisions to house her 70 men strong crew and a few additional passengers relatively comfortably.




Technical Data – Cosmos-class Sea Launch Commander

Length: 199 m
Beam: 32.26 m
Draught: 12.8 m (max.)
Propulsion: nuclear reactor
Speed: 24 knots maximum
Crew: 200 people
Equipment:
    Assembly Bay, clean room,
    command centre, observation deck
Sensors, navigation and processing systems:
    Navigation radar,
    Air Surveillance Radar Array,
    Laige Network,
    Type 901 Datalink
Aviation facilities:
    Helipad
The Cosmos-class Sea Launch Commander is the counterpart of the Odyssey-class Sea Launch Platform, the command and control element of the rocket launches and the launch platform. As a testament to the versatility of the Pattern 253 Freighter, a Dry Bulk Carrier of Handymax-Size, the Cosmos-class Sea Launch Commander is a modified Pattern 253 with the same general profile.
While the shape of the hull is the same, the interior differs very much: Powered by a nuclear reactor, a Ga-17 providing 100 MW, the Cosmos-class Sea Launch Commander is equipped with the most modern command and control facilities available to the civilian market, including a distant cousin of the Artio Battlescape Network, the Laige Network, and the Type 901 Datalink, the civilian cousin of the Type 900 Datalink, which has proven its worth on many vessels, including the Caorthann-class Polar Research Vessel.
The Cosmos-class Sea Launch Commander is equipped with an extensive radar suite, namely a Nuacht N-4 Navigation Radar and a Nuacht N-22 Mark IV Air Surveillance Radar Array, a 3D Air Search Radar Array, a civilian version of the N-22 Mark III as it is used onboard of the Goliath-class Destroyer. With its four arrays, the S-band radar can track up to 500 targets at a range of 400 nautical miles or 740.8 kilometres or up into lower orbit. Additionally, the Cosmos-class Sea Launch Commander carries a GPS-system.
All of these systems connect to the Command Room on the superstructure aft and the Reserve Command Room near the bow, the Command Room being the primary facility to command and control the rocket launch. Much of its arrangement and layout is a reminder of the Glorium-class Command Ship. Above that 'brain' of the whole arrangement is the observation deck, build and equipped for people to watch a launch in a civilized atmosphere with refreshments. Underneath said brain are the quarters for the crew and eventual passengers of the vessel.
On the roof of the superstructure, a helipad for large helicopters is placed, also rated for vectored thrust VTOLs and equipped for refuelling and basic maintenance, but not much more as the Cosmos-class Sea Launch Commander is not equipped with a hangar.
While the Command room is the 'brain' of the Cosmos-class Sea Launch Commander, though, the 'heart' is in the hull, where the cargo would be with a normal Pattern 253. In a way, the assembly bay in the hull, spanning nearly all of it, transports a cargo as well, but the rocket to be launched. Spanning 130 metres in length, with 115 metres being usable for the rocket itself due to the assembly bay doors on the roof being 115 metres in length, it can be used for storage and final assembly of the rocket to be launched, precision engineering sections being included as well as three clean rooms of different sizes, either to be equipped as Laminar Flow Cleanrooms or Turbulent Cleanrooms, depending on the preference of the orderer.
For lifting the assembled rocket out of the bay, a second vessel with a crane is required, as is for loading the bay with the parts to be assembled. The Odyssey-class Sea Launch Platform and her large crane would be an option, but basically any crane should work.




History
Since the Dawn of Mankind, Humanity looked up to the stars and wondered – until, over the course of the 20th century, people were launched into space for different purposes of varying degree of importance.
With the commercial usage of space getting more and more common, the nations and companies of the world started to search for a cheaper solution, from reusable space vehicles to launching at sea, which has a multitude of advantages over classical launches on dry shore, one outstanding above the rest: Due to the mobility of a mobile launch platform, an ideal position can be chosen, which reduces fuel consumption of the rocket and increases payload, making it cheaper to launch heavier payloads into orbit.
The pair of Cosmos-class Sea Launch Commander and Odyssey-class Sea Launch Platform is based on two requests for prototype development by the Avalon Astronautics Alliance, a valued partner of SDY ever since the development and launch of the satellites for the Artio Battlescape Network.
Construction took a while due to the challenge it posed, the chief engineer of Yard 15 gleefully accepting it.

Hjemland-class Sailing Vessel

Postby The Selkie » Tue Feb 21, 2017 2:16 am

Technical Data
Displacement: 3,757 tons full load
Length:
    102.5 m from bowsprit to spanker,
    82.5 m at waterline
Beam: 16.7 m
Draught: 7.1 m
Propulsion: sails, three masts
Boats carried:
    2x 10 m tenders,
    2x 9 m cutters,
    1x 9 m captain's boat,
    all capable of acting as pushboats
Complement:
    250 ship's crew,
    Marine Complement of 50 soldiers,
    Addtional crew depending on configuration
The Hjemland-class Sailing Vessel is the result of a request for prototype development issued by Queen Ashla of Barisea, to provide her Naval Forces with a sailing flagship. The order was, in coordination with the Queen, modified to something more technically possible and capable in its intended role.
These modifications include the possibility to be adapted as a Sail-Training Vessel and Ceremonial Flagship in the future – or the present, should the customer wish so.
Like with the Majestic-class Boat before her, SDY's Yard 15 closely cooperated with Bád Industries Limited, who usually build pinnaces and yawls for our vessels.

Design
The Hjemland-class Sailing Vessel is a 4,000 tons heavy, 102.5 metres long sailing vessel with three masts, closely resembling the Taiscéalaí-Type Vessel, a type of sailing vessel used in the 19th century as a exploration and transport vessel.
It is a monohull design build of fibreglass with aluminium masts, light and still strong enough to support both the weight and the construction itself. The decks are planked with wood.
Watertight hatches, amongst them the cargo hatch, lead below deck, of which there are six full decks and two additional ones: The Main Deck, the Upper Gun Deck, the Lower Gun Deck, the Berthing, the Orlop and the Hold. Additionally, there is the Quarterdeck at the stern of the vessel with a small cabin mounted on it, giving the ship an additional Poop (which has nothing to do with the vulgar term for bodily functions, but actually stems from the French term of la poupe, which means stern).

Propulsion
As typical for Taiscéalaí-Type Vessels, or Explorer-Type Vessels, as they are called in international scientific literature, are distant cousins of the Barquentine rig used in the 19th century, with a square-rigged foremast and fore-and-aft rigged main and mizzen masts.
It requires a smaller crew then fully square-rigged ships, offering good performance before the wind and and the ability to sail close to the wind as well, all while carrying a big load – of course, the Hjemland-class Sailing Vessel is not a cargo vessel, but the other main advantages still apply. The fore-and-aft rigged sails can be operated easily and efficiently, while the square-rig offers the long-distance speed required by modern sailing vessels, while also retaining the 'cool look' of a square-rigged mast appearing on the horizon.

Power is generated via wing generators atop of the masts, each one metre high, providing enough power for all the electrical systems aboard and storing the excess in battery packs beneath the masts. Additionally, the Hjemland-class Sailing Vessel is fitted with two hydrogenerators, which use the forward motion of the vessel to generate power and to store it in the batteries.
The electrical parts of the vessel are specifically designed to be maintained by a car mechanic, if necessary.

Crew
The Hjemland-class Sailing Vessel is crewed by 250 men and women ship's crew, plus optional space for an additional 130 cadets on cruise, see Retrofit Kit Cadets.
In addition to the crew and a small complement of marines, or so-inclined soldiers, the Hjemland-class Sailing Vessel needs a certain amount of stewards aboard to operate completely up to its capabilities due to the amenities of the vessel. Depending on the individual preferences in counts and skills, the estimated minimum number of stewards needed is around two dozen people for the basic version.
This, of course, changes with additional amenities.

Amenities
The Hjemland-class Sailing Vessel comes in the basic configuration with a luxury suit on the Quarterdeck to house VIPs and guests of the vessel, which has exclusive access to a balcony at the stern of the vessel, which can also be used as a small outdoor dining area. The exact interior decoration is up to the customer itself, while a bathroom is provided.
Beneath that, at the stern of the Upper Gun Deck, are two suites for diplomatic guests, their entrance and exits to the deck separated from the Gun Deck by a wooden wall, which also supports the superstructure. These suites' interior decoration is up to the customer himself, but a small bathroom is provided for both suites.
The Commander is housed in a small deckhouse underneath the mizzen mast, aft of the cargo hatch. While, again, the exact interior decoration of the vessel is up to the customer, the deckhouse includes a radio room, with the radio using the mizzen mast as an antenna, as well as the space for an Admiral's staff to work from and an Operations Centre, as well as a secondary bridge, should the primary one be unusable.
The Main Deck can be, with a few quick modifications, transformed into an outdoor ball room, including lighting, buffet, as well as provision to be roofed with oilskin tarps to ward off rain. Security railing for less navally inclined visitors can be build up as well.
The galley, placed on the berthing deck, is equipped with state-of-the-art cooking and food storage facilities, including fridges, deep freezers and a few others. Secured against possible fires by both manual fire extinguishers and a fire sprinkler system. Before installation of domestically produced devices, we recommend reading the manuals. Most of the hearths are induction hearths, but gas cookers can be fitted as well (we highly recommend induction hearths).

The Berthing for the Crew and additional personnel on board was inspired by capsule hotels, the first vessel of SDY's production to receive such a berthing arrangement, as these are cheap and small enough to provide a maximum amount of comfortable accommodations for the crew including privacy by curtain. The capsules, modular and relocatable fibreglass blocks, measure 2.5 metres in length, 1.25 metres in width and 1.5 metres in height, with a small mattress of 2.25 metres in length and 1 metre in width being provided. A closable cupboard running along the side of the capsule provides storage space for the inhabitant's belongings, while a locker is for larger stuff. A foldout panel by the entrance to the capsule is usable as a working surface. Cleaning facilities are communal.

Boats
The Hjemland-class Sailing Vessel comes with five boats, two tenders of ten metres, two cutters of nine metres and a captain's boat of eleven metres. The tenders and the cutters are held on gravity davits, which can be manned on deck level and then can be lowered into the water by one man releasing the brake.
The captain's boat itself is a cabin cruiser, equipped with a toilet, a galley and three berths, one in a 'captain's room' and two in the aft cabin, as well as a small dining area. The model also comes equipped with heating, air conditioning and power generators, as well as a small water heater.
Alternatively, the captain's boat can be replaced by a Majestic-class Boat at no additional costs.
Several pushplates along the waterline and a reinforced boat structure guarantee, that the boats can be used as pushboats to manoeuvre the vessel into the desired position, for example for docking.
The boats are provided by Bád Industries at no additional costs.

Retrofit Kits
The Hjemland-class Sailing Vessel can be used in numerous ways, which can all be achieved by the Retrofit Kits. Please keep in mind, that the equipment installed, especially in case of the Armament Kits, is permanently installed, no removal possible without tearing apart the vessel itself.

Armament
Technical Data – Armament Retrofit Kits
Kit A – Broadsider
    4x 190mm breech-loading rifled guns – Gabha G-990
      Barrel Length: 8.6 m, 42 calibres
      Muzzle Velocity: 900 m/s
      Maximum firing range: 20 kilometres
    8x 135mm breech-loading rifled guns – Gabha G-991
      Barrel Length: 6.7 m, 50 calibres
      Muzzle Velocity: 820 m/s
      Maximum firing range: 22 kilometres with HE
    8x Saluting Guns
    4x Split-Image Rangefinders or 2x Laser Rangefinders
Kit B – Salutations
    8x Saluting Guns
There are three options for armament kits:
Armament Kit A:
    Armament Kit A consists of four 190mm breech-loading rifled guns with 45 calibres, the specially developed Gabha G-990, and eight 135mm breech-loading rifled guns, the specially developed Gabha G-991, as well as eight Saluting Guns. Ammunition for both is stored on their respective gun decks in an armoured box with conveyor belts, either hand- or electrically-operated, bringing the rounds to their respective guns.
    The G-990 is a derivative of the 190mm guns planned to be used on never-built SDF-Navy Heavy Cruisers in the first half of the 20th century, mounted in a box battery on the Lower Gun Deck, giving a heavy broadside, especially due to the guns range of 20 kilometres and a traverse of fourty degrees to the left and the right. The specially reinforced barrel, or built-up gun, can withstand the explosion of stronger charges then cordite as well, ease of reloading is guaranteed by a breech block.
    The G-991 is a derivative of the 135mm guns used on SDF-Navy Light Cruisers and which have been planeed as the Heavy Cruiser's secondary armament in the first half of the 20th century. Grouped into four groups of two, two close to the stern, two by the bow in their own little battery boxes, these 135mm guns fire a 36 kilograms shell over a distance of 21 kilometres at a higher rate of fire then the G-990, thanks to a smaller calibre and smaller shells. Each gun has a traverse of thirty degrees to either side.
    Both the G-990 and the G-991 can be loaded with many different kinds of ammunition, amongst others High-Explosive, Armour-Piercing, APDS, APDSFS and many more.
    Armament Kit A also involves the armouring of the Gun Decks with armoured steel.

    Purchasing Armament Kit A will block the Gun Decks from any other kind of modification.

Armament Kit B:
    Armament Kit B consists of eight Saluting Guns on the Main Deck, guns with make a whole lot of noise and produce a huge puff of smoke when fired straight into the air, in order to salute dignitaries or harbours when arriving. Their main function is diplomatic courtesy.

Sensors and Communications Equipment
The Hjemland-class Sailing Vessel comes in its basic functionality with a fully equipped with a radio room and a GPS Receiver. This can be expanded, if that is wished, by adding a Surface Search Radar, a Navigation Radar and a satellite uplink system.
All of this would be installed on the masts, in part using the masts as antennas.

Oceanographic Research Equipment
In addition to any other equipment on board, the Hjemland-class Sailing Vessel can be used as a Oceanographic Research Vessel, given the right equipment. That includes equipment to survey the physical, chemical and biological characteristics of water, atmosphere and climate, as well as equipment of hydrographic sounding of the seabed and other environmental sensors.
Control, storage and maintenance facilities for unmanned underwater vehicles and medical facilities for divers can be included as well, although the UUVs replace the two cutters. A mobile catapult for small UAVs can be fitted as well.

The Oceanographic Research Facilities are constructed to be fitted on the Gun Decks.

Engines
Generators:
    A must if additional electrical systems are to be installed, a diesel generator of 2000 kW can be installed on the Orlop Deck together with the fuel tanks. It provides the necessary power for all electrical equipment one might need on board, including more advanced sensors.
    A generator bars the Orlop Deck from any other kind of modification, but can be installed together with an IEP-system.

IEP:
    If the customer wishes, the Hjemland-class vessel can be equipped with an Integrated Electrical Propulsion System, providing power to the vessel via a diesel generator of 4000 kW, which not only drives the additional electrical equipment aboard, but also an electrical engine, which is, together with a set of two small controllable propellers, are able to act as auxiliary engines and to speed the vessel up to 11 knots even without wind.
    An IEP-System bars the Orlop Deck from any other kind of modification, but can be installed together with an IEP-system.

Amenities
Cadets:
    The Hjemland-class Sailing Vessel can be modified to accommodate up to 130 cadets for sail training and other purposes. Being placed on the Berthing-Deck, the cadets in question will receive the same amenities then the other sailors aboard.

History
Sailing, using the power of the wind to propel a vessel forward, is one of the oldest ways of indeed going to sea, moving to distant shores in order to trade, settle and do a whole lot of other things in the process. In the
In the closing years of the 17th century, boat-builders of the Free Lands developed vessels which were later called the Early Taiscéalaí-Type Vessels or Explorer-Type Vessels. Easy to operate, fast even when loaded to the brim, needing only little in the way of an actual crew, these vessels were the pride of their owners, who sailed the oceans wide on them.
They weren't really wide spread due to the costs involved in actually building such vessels and these vessels themselves being used for a magnitude of different purposes, usually far away from larger harbours – the first settlers of the town, that would later become Rua in the Northern Islands, in fact came with a Early Taiscéalaí-Type Vessels.
They were, however, not without faults, so the Taiscéalaí-Type Vessels had some much needed improvements, amongst them a larger cargo hold and a new rigging, which made the Taiscéalaí-Type Vessels more resistant to storms and faster in general.
With the advent of steam engines as method of propulsion for vessels, the Taiscéalaí-Type Vessels fell out of use and were slowly, but steadily moved to different roles, which could not be filled by steam-powered vessels, only to be replaced there as well.
The last newly built Taiscéalaí-Type Vessels was put into service in 1932, serving as a survey ship for the Northern Islands Constabulary.

As in early 2017 the Queen of Barisea, Ashla, came to Silverport Dockyards Limited with the request for a flagship for her navy, which was something SDY agreed to construct with the help of Bád Industries, with whom we worked together before quite successfully.
In agreement with Queen Ashla, the original plans for the vessel were changed a bit and adapted for adaptability - together, a new vessel fit for a multitude of operations was born: The Hjemland-class Sailing Vessel, usable in a multitude of different functions, from war to training.

Pricing
One Hjemland-class Sailing Vessel, basic price: 200 million NSD.

Retrofit Kits:
    Armament Kit A: 125 million NSD.
    Armament Kit B: 1 million NSD.

The Rhiannon-II-class Guided Missile Frigate is a design of a multi-role patrol frigate, incorporating capabilities against sub-surface, surface and air threats. They are constructed to act as the workhorse of a navy.
In their secondary function, the Rhiannon-II-class Guided Missile Frigate is to serve as an escort vessel for larger units.

Rhiannon is the Goddess of Horses and Fertility in the Selkie-Pantheon. The name Rhiannon for a vessel has a long-standing tradition within the SDF-Navy, beginning with the first SDFS Rhiannon, a light cruiser in the 20s. Ships named Rhiannon have a place in the annals of Selkie-History, beginning long before the light cruiser.

Design
The Rhiannon-II-class Guided Missile Frigate is a classical steel monohull design, 4,800 tons on normal load, 140.8 meters long, with a beam of 16.9 meters and with an average draught of 4.9 meters, enabling it to operate closer to shores then many compareable designs. However, the Rhiannon-II-class Guided Missile Frigate is not a brown-water vessel, but a green-water vessel, capable of operating close to shores and on open seas.

As many of SDY's newer designs, the Rhiannon-II-class Guided Missile Frigate was designed with stealth-measures in mind, but is not a fully dedicated stealth-vessel. This is mainly achieved by simple measures in the construction, inclined flanks, few vertical lines and very clean lines in general. This makes the Rhiannon-II-class Guided Missile Frigate appear on a radar to be around the size of a medium-sized fisherboat. The use of radar absorbing synthetic materials while building the superstructure adds to that effect.
Although radar is one of the most common ways of detecting surface combattants, it isn't by far the only way. The thermal signature is reduced by funneling the exhaust gases of the engines through a series of small pipes instead of one large stack, exiting the ship at a lower temperature to the vessels sides instead of directly above it like a large signal.
Speaking of the engines, this major provider of an acoustic signature is silenced by being settled on noise absorbers, mainly vibration absorbers, which absorb the engines' vibrations and nullify them.

The Rhiannon-II-class Guided Missile Frigate has a helipad, rated to handle VTOLs with vectored thrust as well, and a fully-equipped hangar for one medium-sized helicopter. The Rhiannon-II-class Guided Missile Frigate can carry a second helicopter on the pad.

Propulsion
The Rhiannon-II-class Guided Missile Frigate's power is provided by four diesel generators, each capable of providing 9,500 kW of power. Being a derivative of the engines used on the Faolchu-I-class FAC, these high-power engines consume less fuel at the same performance, powering all of the ship's systems, including the electrical engines driving the two propellers. This system, called Integrated Electrical Propulsion, or IEP for short, saves fuel and maintenance costs while freeing valueable space aboard the vessel.
For enhanced maneuvreability and more economic energy consumption, the Rhiannon-II-class Guided Missile Frigate is equipped with controllable pitch propellers, which can be put into reverse pitch as well. As such, the vessel can reach a maximum speed of 32 knots and has a maximum range of 10,000 nautical miles at cruising speed.

Decoys
Centre of the decoy-suite is the Multi-Ammunition Softkill System, MASS for short. The system is connected to the radar and uses the data from these systems to launch radar decoys operating on the relevant wavelengths of the electromagnetic spectrum. This serves to confuse advanced, sensor-guided missiles. It can either be operated by a sailor or operate autonomously.
Additionally, the Rhiannon-II-class Guided Missile Frigate is equipped with a torpedo-decoy dispenser, namely a three-part system: A towed array, integrated into the VDS, for the detection and identification of torpedoes and their heading, a towed countermeasure, and two launchers for expendable decoys, one on port and one on starboard, which generate a more tempting acoustic signature, which in turn lure the torpedo away. This system is known as the Baoite Mark III.

Electronic Warfare
The Rhiannon-II-class Guided Missile Frigate is equipped with a large suite for electronic warfare, composed of a suite for Electronic Countermeasures, Electronic Protection and Electronic Support Measures.
Electronic Countermeasures, or ECM for short, are used to deceive and trick enemy means of detection and ultimately not having a guided missile slam into the ship's side. Be they sonar decoys or radar jammers (Rasberry Jammers is the system we usually use), active ECM measures confuse the enemy's sensors, while passive measures include for example the jamming of the guidance systems of enemy missiles.
Electronic Support Measures meanwhile detect, intercept, identify, locate, record and analyze sources of radiated electromagnetic energy (for example radar) for threat recognition and other purposes, amongst them intelligence information. With these information, a commander can make the tactical and, if necessary, strategic decisions needed. It also provides the means necessary to gather information about the Electronic Warfare Systems of the enemy either in order to avoid an attack or to attack more effectively.
With Electronic Protection (EP), or Electronic counter-countermeasures (ECCM), the vessel is hardened against every kind of electronic attack, for example against scrambling and jamming. This allows to attack the enemy even when he feels safe with his jammers in place and activated.

These multifunction radars can also be used for weather forecasts, as navigation radars and for secondary fire control, but find their true calling in the detection and identification of threats on the surface and far above it, be they missile or aircraft or any type of ship. The data collected by the N-13 Radars is then transferred to the operations centre via the Type 900, where the crew can act based on this data.
Specialized in air search, the N-41 Mark III 3D Long Range Air Search Radar provides information about any given target, especially elevation, range and azimuth, while being capable of tracking 150 targets at once. It is a passive electronically scanned array radar. Besides its primary function as an air-defense and surveillance radar, the N-41 can also be used as a weather radar, but is not built for such a function and should be used in such a capacity only in emergencies.
The radar suite is completed by two N-38 Fire Control Radars, which are used to guide semi-active radar homing missiles, illuminating targets for the own missiles. As the guns aboard the Rhiannon-II-class Frigates possess their own fire control radars, the N38s are not needed in that function, but could theoretically be used in such a manner.
Additionally, the Rhiannon-II-class Guided Missile Frigate is equipped all around with infrared search and track sensors (or IRST Sensors for short), providing detection against everything emitting infrared radiation such as for example jet aircraft, helicopters or missiles, at a distance of up to 100 kilometres, depending on weather condition. This is especially useful in combatting stealth aircraft or in defending the own ship when the radar is not capable of operating due to jamming or similar measures. As the IRST is an array of passive sensors, it is hard to detect them operating.
For the detection of targets beneath the surface, and ultimately combatting them, the Rhiannon-II-class Guided Missile Frigate is equipped with a bow-mounted active sonar system and a Variable Depth Sonar, a Nuacht N-81 Mark II VDS. The latter system is capable of detecting submarines at a distance of up to 150 kilometres at an accuracy of less then 100 metres at maximum range, operating in very rough seas as a system for passive and active surveillance 360 degrees around the Rhiannon-II-class Guided Missile Frigate, analysis of any received signal (and keeping apart, if it is a whale or a submarine), audio output and a torpedo alert. Hanging at a single tow line, the Nuacht N-81 Mark II VDS can actively send out pulses while passively detecting sounds made underneath the surface as well in every direction.

The Type 900 Datalink is a system for Duplex Communication in both directions in real time, processing said data in real time as well. Not only sensors and weapons are connected by this system, but virtually everything onboard the ship, from consoles on the bridge to the mobile coffee maker by the helipad. Personal Computers and gaming devices of the crew use another system, utilizing a satellite uplink and being diconnected from the Datalink in every way, shape and form imagineable.
To exemplify the processing power of the Type 900 Datalink: When the first prototype of the Type 900 was supposed to be tested, the corresponding department in Laclan hosted a LAN-party with roundabout ten thousand participants (4,157 at height) playing 25 different games - with the 'Local Area Network' reaching across the entirety of the Free Lands with no lags whatsoever.

Artio Battlescape Network Mark III-D
Another important system aboard the Rhiannon-II-class Guided Missile Frigate is the Artio Battlescape Network Mark III-D. Via directed data-transmission, each ship can share data by direct line of sight, around 40 kilometres due to the transmitters being placed on a specialized mast.
Although this system can be disrupted, albeit with a whole lot of difficulty, no one can listen in. The direct line of sight also requires, that no obstacles are between the transmission stations, which are kept in line by the Type 900. However, this range can be made next to unlimited by hooking up the whole system to a satellite, which can share the data needed without any problems.
Although normal telecommunication satellites can be used for this purpose, Silverport Dockyards Ltd. has made an invitation for bid to a few companies specialized in such things, hoping to be capable of offering a complete system with a specialized satellite by 2018. The Artio can be connected to major Battlescape Network Systems, but we highly recommend reading the manual.

The Rhiannon-II-class Guided Missile Frigate is armed with a weapon's suite for both offensive and defensive purposes, both against targets in the air, on the surface and beneath the waves, emphasizing the versatility of these Guided Missile Frigates.
Placed on the foredeck, the heaviest gun aboard the Rhiannon-II-class Guided Missile Frigate is the Túirín T-12 Mark II, a double-barrel 76mm gun, capable of acting as an auxillary AA-gun and CIWS, for shore bombardements and as a general deterrent against an enemy, which is less armed. Multiple kinds of ammunition, like fragmentation or HE-rounds, can be flung over a distance of 27.5 kilometers with this gun.
Solely defensive in nature are the two Ceantar C-84 Mark II 30mm CIWS, which aim with their own little radar, capable of operating fully autonomously against any incoming missile, be it aimed at the Rhiannon-II-class Guided Missile Frigate itself or at one of the vessels under her watch. They are placed on either side of the superstructure.
Main armament of the Rhiannon-II-class Guided Missile Frigate are its six Feadán Fe-12 Mark II 8-cell VLS-modules, capable of being loaded with basically every hot-launched missile, which fits into the 2.5x2.6x8 metre cell (we recommend reading the manual). The SDF-Navy plans to equip the Rhiannon-II-class Guided Missile Frigates with a combination of quad-packed Surface-to-Air Missiles, ASROC and AShMs, as well as a module free for mission-specific armament.
Core of the weapons suite optimized against submarines are the two triple packs of 533mm torpedo tubes, two Feadán Fe-32 Mark I on either side of the vessel, which, as the name suggests, are capable of launching 533 millimetre torpedos at any given target with compressed air. The Rhiannon-II-class Frigate is capable of carrying 18 torpedoes with her safely, six in the barrels and twelve on stock, and up to 24, but on the cost of ammunition for the 76mm gun.
Additionally, the Rhiannon-II-class Guided Missile Frigate has four balconies, positions on the superstructure designed for mounting heavy machine guns, autocannons like the SDY-Gabha SG-1 Mark III, remote weapons stations or serving as positions for riflemen and marksmen to operate from.

History
The Rhiannon-II-class Guided Missile Frigate began their life as the Rhiannon-IB-class Frigate, an upgrade to the already existing six Rhiannon-class Frigates of the SDF-Navy, in 2010. Soon, both the SDF-Navy and SDY realized, that the Rhiannon-I-class, despite being excellent vessels, was not really capable of handling major updates like the one the SDF-Navy had in mind without major yard stays or costs involved.
So, Rhiannon-IB died before it even lived and was replaced by an entirely new design, the Rhiannon-II-class. Originally planned as a Multi-Purpose Frigate, the Rhiannon-II-class Frigate slowly evolved into a Guided Missile Frigate, capable of acting as an active surface combattant as well as an escort for other vessels, who's main armament were its guided missiles.
The SDF-Navy showed great interest in these vessels, both due to the need to replace the Rhiannon-class Frigates, and due to the new threats faced by the SDF-Navy in the near future. As soon as the first design studies were finished, the SDF-Navy financed a first batch of six Rhiannon-II-class Frigates to be named after the Six of the Selkie-Pantheon (Rhiannon, Carman Fea, Abhcan, Gavida, Lodan Lir and Ladra) and to replace the frigates of the same names currently in service.
Commissioning for the first vessel, SDFS Rhiannon, is expected for the Spring Festival in Silverport of 2017.

The Tuirlingeoir-class Landing Boat, Tank, or Tuirlingeoir-class LBT for short, is a landing craft doubling as a minelayer designed and produced by Silverport Dockyards Limited as the answer to the request for a small tank-landing and vehicle-landing ship by the SDF-Navy. It is designed specifically for short-range operations, in support of own operations close to shores and to transport own vehicles and equipment, not as a tool for expeditionary warfare.

Tuirlingeoir means lander, which is an appropriate name for a landing boat.

Design
The Tuirlingeoir-class LBT is a design of difficult proportions, as the vessel itself is a monohull, but the bow is blunt and therefore increases the drag of the vessel in the water when, for example, compared to a vessel with a sharper bow. This, however, also allows for two core capabilities of the Tuirlingeoir-class LBT, namely the capability to approach and deliver its load directly onto the shore via beaching and for that to be done with a large ramp on the bow in a relatively simple and classical design.
From the bow up, the Tuirlingeoir-class LBT has five decks, namely the Hold, with the engine room and storages, as well as ballast, two troop decks (Third and Second Deck), the Main Deck with the deckhouse and the bridge.
The Third Deck, also known as the Vehicle Deck, has major store rooms for troop supplied and a workshop for maintaining the vehicles parked there. Several storerooms provide enough space for the provisions in question. The Second Deck houses the soldiers themselves, albeit not in much comfort, has the mess and a sickbay, which can double as a small field hospital.
The Main Deck has the large cargo hold doors, which can be opened to allow access to the Vehicle Deck, as well as the lower story of the deckhouse, where the crew is housed, together with an own galley and a small recreational room for the crew.
On top of that is the brain of the ship, the bridge, with access to all functions of the vessel.

The Tuirlingeoir-class LBT can carry either up to eight Main Battle Tanks or sixteen loaded trucks or 130 fully equipped soldiers or a combination of those and deliver them safely onto shore.
Additionally, the vehicle deck can be modified partially or completely to act as an enlarged vehicle repair workshop, as a field hospital or in a multitude of other functions directly at the shore, circumventing the need for the establishment of other such facilities immediately.
The Tuirlingeoir-class LBT can be either loaded by driving the vehicles in question onto the vehicle deck via the ramp or by lowering the vehicles in question onto the vehicle deck by crane, thanks to large cargo hold doors on the maindeck.

The Tuirlingeoir-class Landing Boat, Tank is also equipped with an ECM-system, a Multi-Ammunition Softkill System and a small navigation radar, both placed on top of the bridge.
The vessel itself is lightly armoured, capable of stopping 14.5 mm bullets head on.

Propulsion
The Tuirlingeoir-class LBT is powered by a 5 Megawatt diesel generator, much akin to the ones used onboard of the Port Hackburry-class Fleet Oilers, only singular. The principle is the same: The Integrated Electric Propulsion allows for a generator to produce the power necessary to operate the ship's systems, transferring them to the different systems, like to the radars or the engines, via cable, where the major advantage of IEP comes in, namely, that the need for maintenance-costly gearboxes is completely eliminated, space itself saved and acquisition costs are lowered.
The power of the generator and the corresponding engine allows the Tuirlingeoir-class LBT to travel with a speed of seventeen knots maximum and over a distance of 800 nautical miles at full load.

    1x 30mm CIWS - Ceantar C-84 Mark II
      Calibre: 30mm
      Barrels: 6
      "Magazine": 2000 rounds
      Elevation: -10 to +88 degrees
      Traverse: 360 degrees
      Rate of fire: 4,500 rpm
      Muzzle velocity: 950 m/s

      Maximum Firing Range:
        20-45 kilometers (depending on rocket)
    2x smoke rocket launchers
    2x balconies
    Provisions to carry 135 naval mines
The Tuirlingeoir-class LBT is only lightly armed, mostly for self-defence and to support the landing troops.
Core of the weapons suite is the CIWS, a singular Ceantar C-84 Mark II, housed on the forecastle, where it is capable of providing cover against incoming larger missiles, as in missiles larger then an RPG, from nearly all angles with a traverse range of 140 degrees to either side (theoretically, it is capable of turning the whole 360 degrees, but the superstructure limits the effectiveness of this capability due to clearance issues). It can either be controlled manually or set on automatic fire, which we would recommend since the C-84 is equipped with its own targeting radar and fire control mechanisms.
Together with the two smoke rocket launchers, basically enlarged versions of the smoke grenade launchers mounted on modern Main Battle Tanks, the Tuirlingeoir-class LBT can provide smoke cover for its own approach and unloading. These launchers can also be fitted with decoys to confuse enemy radar or infrared homing missiles. Alternatively, the smoke rocket launchers could be replaced by normal smoke generators or similar systems.
For the support of ground troops, the Tuirlingeoir-class LBT carries one Feadán Fe-21 Mark III MRLS, the weapon system on the back of Gabha Blacksmith's Saighdeoir-MRLS, a launcher for dumbfire missiles, capable of firing thirty 122mm artillery rockets at a given target, providing they are shorter then 3.1 metres. This is meant to support operations close to shore with artillery rocket fire.
The Tuirlingeoir-class LBT has two so-called balconies as well, positions on the superstructure designed for mounting heavy weapons or remote weapons stations, which then can be used as additional weapons positions for fire support.

In addition to all of that, the Tuirlingeoir-class LBT has the provisions to carry and deploy 135 naval mines of different types at the aft of the vessel to act as an auxiliary minelayer. The minelaying equipment can be removed and the space made free by that can be used for other purposes.

History
Ever since the first contingent of troops was moved to a distant shore there was one question plaguing naval engineers, strategists and generals: How do I move my troops onto shore quickly, without much loss in operative capability and safely?
Ever since that first contingent, the ways to actually do so evolved.
In 2012, after the fateful Battle of Marley Bay, part of the Halfblakistani Intervention, the SDF-Navy began to search for a new Landing Boat to replace the ageing fleet of freighters used as part of the Auxiliary Freighter Group with something more practical.
One of the result of that request for proposals was the Tuirlingeoir-class LBT, a vessel for relatively short-ranged operations, like in archipelagos or mediterranean seas.
It's capabilities can not be overstated: As an easy and cheap way to bring vehicles to shore, the Tuirlingeoir-class LBT adds bang to any invading force with ease and support.

The vessels already had their baptism by fire: Tuirlingeoir, a vessel of SDY's Yard Fleet at the time, was provided by SDY to the relief efforts to Bolcán Island after it was hit by a severe winter storm in late 2016, shortly before the end of the year, transporting equipment and material to the island and wounded from the island to Wembury in order to be treated. This aid proved valuable to the relief effort, an official later said.
The SDF-Navy showed interest and plans to acquire several of these vessels, as do a few civilian contractors, who plan to use these vessels as vehicle ferries – a demilitarized version for them is in the works.

The Meantán-class Landing Boat, Tank, or Meantán-class LBT for short, is a large landing craft designed and produced by Silverport Dockyards Limited as the answer to the quest for a roughly corvette-sized tank-landing and vehicle-landing ship by the SDF-Navy and the navies of two friendly nations. It is usable in its primary military function as a landing boat, as a disaster relief vessel and as a demilitarized RoRo-ferry, amongst other things.

The term Meantán refers to the Paridae family of small birds.

Design
The Meantán-class LBT is a classical monohull design with a sharp bow, circumventing the problems of speed, range and power, which the smaller, but no less capable Tuirlingeoir-class LBT has. Designed for beach landings, the Meantán-class LBT can carry up to ten Main Battle Tanks and 340 soldiers, plus supplies, or 600 tons of cargo or any configuration of that mass and size on the 630 square-metres vehicle deck spanning the entirety of the vessel.
Loading and unloading are done via bow doors, which also hide a ramp to be lowered onto the beach, via the rear doors, which enable the Meantán-class LBT to also deploy amphibious assault vehicles, smaller landing craft or small dinghies, or via the long sliding hatch on top of the vehicle deck. The Meantán-class LBT is designed for RoRo-Operations. Additionally, the vehicle deck can be modified partially or completely to act as an enlarged vehicle repair workshop, as a field hospital or in a multitude of other functions directly at the shore, circumventing the need for the establishment of other such facilities immediately.
The Meantán-class LBT is able to house a staff and command of a landing force, enabling it to conduct operations without the need for an amphibious force flagship nearby, if need should arise.

Propulsion
The Meantán-class LBT is one of SDY's vessels using the propulsion arrangement called Integrated Electric Propulsion, being powered by two Diesel Generators, which each provide 3 Megawatts, which power everything on the ship, lowering the costs for maintaining and acquiring these vessels as this also reduces the amount of gearboxes needed for bringing power from the engines to the propellers to zero.
This also has the advantage of enabling the Meantán-class LBT to be equipped with two azimuth-thrusters or engine pods, where the propellers are fitted onto pods, which can turn horizontally, making a rudder effectively unnecessary and making the vessel far more maneuvreable, enabling the Meantán-class LBT to, for example, dock by itself without the assistance of tugboats. The electrical engines used to power the propellers are in these pods, which can easily be replaced and maintained.
With these systems, the Meantán-class LBT can reach a maximum speed of 20 knots at a range of 6,000 nautical miles at 15 knots.

Sensors, Processing Systems and Electronic Warfare
Technical Data - Radar Suite
1x Nuacht N-12 Mark II Air/Surface Search Radar (Multi Function)
    Bands: X
    Range: 400 km
    Height of target: 9.5 km
    Power: 100 kW
1x Nuacht N-38 Fire Control Radar
1x Nuacht N-4 Navigation Radar
The Meantán-class Landing Boat, Tank is equipped with an powerful radar suite.
The core of it is the proven and capable Nuacht N-12 Mark II Air/Surface Search Radar, a multi function radar capable of acting as air search radar and as a surface search radar, capable of detecting and, in cooperation with the weapons systems, eliminate threats of these kinds against the vessel and its cargo. The N-12 is one of the most-used radars of SDY and has been proven on multiple occasions.
Supplementing the N-12's capabilities are a N-38 Fire Control Radar, used for tracking the paths of the own ammunition for corrections and aiming, as well as a N-4 Navigation Radar needed to find the way.
All of these radars are connected to the bridge and other systems by the Type 900 Datalink.

The Type 900 Datalink is a system for Duplex Communication in both directions in real time, processing said data in real time as well. Not only sensors and weapons are connected by this system, but virtually everything onboard the ship, from consoles on the bridge to the mobile coffee maker. Personal Computers and gaming devices of the crew use another system, utilizing a satellite uplink and being diconnected from the Datalink in every way, shape and form imagineable.
To exemplify the processing power of the Type 900 Datalink: When the first prototype of the Type 900 was supposed to be tested, the corresponding department in Laclan hosted a LAN-party with roundabout ten thousand participants (4,157 at height) playing 25 different games - with the 'Local Area Network' reaching across the entirety of the Free Lands with no lags whatsoever.

The Meantán-class Landing Boat, Tank is equipped with an extensive Electronic Warfare Suite, composed of systems for ECM, ESM and EP, which provide the Meantán-class Landing Boat, Tank with the means to defend itself against an enemy and to actively disrupt him.
Electronic Countermeasures, or ECM for short, are used to deceive and trick enemy means of detection and ultimately having a guided missile slam into the ship's side. Be they sonar decoys or radar jammers (Rasberry Jammers is the system we usually use), active ECM measures confuse the enemy's sensors, while passive measures include for example the jamming of the guidance systems of enemy missiles.
Electronic Support Measures meanwhile detect, intercept, identify, locate, record and analyze sources of radiated electromagnetic energy (for example radar) for threat recognition and other purposes, amongst them intelligence information. With these information, a commander can make the tactical and, if necessary, strategic decisions needed. It also provides the means necessary to gather information about the Electronic Warfare Systems of the enemy either in order to avoid an attack or to attack more effectively.
With Electronic Protection (EP), or Electronic counter-countermeasures (ECCM), the ship is hardened against every kind of electronic attack, for example against scrambling and jamming. This allows to attack the enemy even when he feels safe with his jammers in place and activated.

Artio Battlespace Network Mark III-C
Another important system for effective operation of the Meantán-class Landing Boat, Tank is the Artio Battlescape Network Mark III-C. Via directed data-transmission, each ship can share data by direct line of sight, around 40 kilometres.
Although this system can be disrupted, albeit with a whole lot of difficulty, no one can listen in. The direct line of sight also requires, that no obstacles are between the transmission stations, which are kept in line by the Type 900. However, this range can be made next to unlimited by hooking up the whole system to a satellite, which can share the data needed without any problems.
Although normal telecommunication satellites can be used for this purpose, Silverport Dockyards Ltd. has made an invitation for bid to a few companies specialized in such things, hoping to be capable of offering a complete system with a specialized satellite by 2018. The Artio can be connected to major Battlescape Network Systems, but we highly recommend reading the manual.

      Maximum Firing Range:
        20-45 kilometers (depending on rocket)
    2x remote weapons stations
    4x balconies
The Meantán-class LBT is equipped with an extensive weapons suite, capable of defending itself – we still recommend escorts – and landing troops, as well as providing direct and indirect fire support to them.
Core of the defensive capabilities of the Meantán-class LBT are the two CIWS, one on the forecastle, the other one on the quarterdeck, providing maximum coverage against incoming missiles and venturing hedgehoppers. The two systems, both Ceantar C-84 Mark II, can either be controlled manually or set on automatic fire, which we would recommend since the C-84 is equipped with its own targeting radar and fire control mechanisms.
The main gun, a double-barrel Túirín T-12 Mark II, 76mm L\50, positioned in front of the superstructure, is capable of acting as an additional auxiliary anti-aircraft gun, but its main mission is the direct fire support of the landing troops, lobbing 76mm shells over a distance of up to 27.5 kilometres, depending on the shells.
Another weapon for the support of landing troops are the two Feadán Fe-21 Mark III MLRS, basically the same MLRS as used on Gabha Blacksmith's Saighdeoir-MRLS, a launcher for dumbfire missiles, capable of firing thirty 122mm artillery rockets at any given target, providing they are shorter then 3.1 metres and the target is within range. While the T-12 has its own little firing control radar, it is, just like the Fe-21, connected to the onboard N-38 Firing Control Radar via the Type 900 Datalink.
Additionally, the Meantán-class LBT is equipped with two Remote Weapon Stations at the bow, capable of handling everything from heavy machine guns to automatic grenade launchers while being remote controlled.
The Meantán-class LBT also has four balconies as well, positions on the superstructure designed for mounting heavy weapons, which can be used as additional weapon positions for fire support. Two of these balconies are large enough and support enough weight to carry light artillery pieces.

History
Ever since the first contingent of troops was moved to a distant shore there was one question plaguing naval engineers, strategists and generals: How do I move my troops onto shore quickly, without much loss in operative capability and safely?
Ever since that first contingent, the ways to actually do so evolved.
In 2012, after the fateful Battle of Marley Bay, part of the Halfblakistani Intervention, the SDF-Navy began to search for a new Landing Boat to replace the ageing fleet of freighters used as part of the Auxiliary Freighter Group with something more practical.
One of the results of that thought process was the Meantán-class LBT, a ship large enough to count as such and to still being called a boat by SDY-custom.
Somewhere along the lines of the development process, two friendly nations, the Protectorate of Our Ladia and the Federal Republic of Herodas, jumped aboard the development process, influencing the design and capabilities of the vessels heavily. This resulted in the navies of these two nations and the SDF-Navy testing the same prototype to the fullest, the Meantán being in Herodan Waters at the time of the Bolcán Island Storm, thus unable to help like their brothers did.
The SDF-Navy plans to build and maintain a group of six Meantán-class LBTs, replacing the Auxiliary Freighter Group with these vessels.

Hope-class Hospital Vessel

Postby The Selkie » Fri Apr 14, 2017 1:20 am

Technical Data
Displacement: 60,000 tons
Length: 242.5 m
Beam: 43 m
Draught: 6.1 m
Propulsion: 2x Diesel Engines, 33 MW total, one shaft
Speed: 16 knots
Crew:
    55 civilian and 1,150 military
    (including nurses and doctors, during active service)
Armament: None
Aviation Facilities: Helicopter Landing Deck
The Hope-class Hospital Ship is the result of a request for prototype development by the Hexoloan Navy, asking for a hospital ship to treat soldiers wounded in military operations. As a hospital ship, in compliance with the Hague Conventions of 1907, the Ships are marked as such, delivered painted in white with the red crystal painted on it, and completely unarmed.
As such, attacking a Hope-class Hospital Ship is a war crime in accordance with the Hague Conventions.

Design
Based on the hull of the Aframax-sized tanker of the Pattern 256, and powered by two diesel engines of the same type as used on the Pattern 256, the Hope-class Hospital Ship is a large Ship, sitting safely in the water. It's reinforced double-hull and a special bow, which allows the Hope-class Hospital Ship to move into icy waters, guarantee the safety of the passengers.
The tanks used to hold crude oil were replaced by decks upon decks of hospital facilities, storerooms and berthing for the nurses and doctors.
The Hope-class Hospital Ship is fitted with ten operating theatres, fully equipped with state of the art medical technology, a facility with eight hundred beds, radiological services, an extensive medical laboratory, a pharmacy with a cooling unit, an optometry lab, a CT-scanner, a dentist and a morgue. In non-medical facilities, the Hope-class Hospital Ship comes with a water distillation plant, two plants for oxygen production, and storerooms to carry supplies in food for a month.
In addition to that, the Hope-class Hospital Ship has a large helicopter landing deck, which can carry up to three medium-sized helicopters and handle patients coming in that way. Another option for patients to arrive is via other ships, including dinghies, which can be lifted aboard via two cranes rated for a maximum of fifteen tons, one on either side of the aft of the vessel.
The Hope-class Hospital Ship carries a multi-purpose radar, capable of acting as a navigation radar and as an air search radar, as well as a civilian sonar to see underwater obstacles. For finding the way, the vessel is equipped with a GPS-Receiver. If necessary, a radio beacon declaring the vessel as a hospital ship and protected under the Hague Conventions can be activated.
As a Hospital Ship in compliance with the Hague Conventions, the Hope-class Hospital Ship is completely unarmed and we recommend leaving it that way. However, for self-defence, the Hope-class Hospital Ship carries a battery of dispensers for chaffs and flares.
Despite being based on an oiler's hull, there are little to no problems with moving patients from one tract to the other, mainly due to the design being basically gutted so that only the hull and structural components remained, before being refilled for the purpose with all the necessary components and decks.
Engines and crew quarters are placed astern, while command and control facilities are in the superstructure, as well as a room for the tools for light maintenance on incoming helicopters, which in no way is capable of replacing a fully fledged hangar and air crew. Quarters for an onboard security team are within the superstructure as well.
Berthing for the medical staff is beneath the hospital wings, which are directly below the main deck, for easier access to the medical wings for incoming patients. It is not comfortable berthing, in fact, there is the option for bunk beds, capsule berthing and hammocks, but it does its job. A few rooms for rest and relaxation are provided as well as a large galley, both for patients and crew. The main storages are below that, but smaller storerooms, especially for medical supplies, are all over the medical wings.
Elevators, a large one for cargo and four smaller ones for up to two stretchers, are installed onboard, the latter evenly spaced out to connect all decks with each other. Staircases are provided as well.
The Hope-class Hospital Vessel also carries a specialized type of lifeboat, the Type 156 Lifeboat of Bád Industries, which is capable of taking aboard patients on stretchers quite easily.

History
Injury and the need for treatment always went hand in hand with armed conflict and disaster – modern times did not really change that. To that end, the sporadic treatment given to injured people aboard vessels of ages long past has given way to organized treatment on ships modified and adapted for the task, protected by international right and law.
Veritable mobile hospitals now cruise on the seas, being able to move to areas affected by war and disaster with relative ease – one of the first purpose-build designs, however, is the Hope-class Hospital Vessel, build on request of the Navy of Hexolo, but also offered to everyone willing to and wishing for a vessel of that kind: A hospital on sea.
At first, SDY thought about designing a new vessel from keel-up, but soon came to the realization, that it would be better adapt a design and build that from keel-up as a vessel dedicated to the task – due to concerns about size and displacement, the choice was made to adapt the Pattern 256, one of SDY's own designs and a tanker. With the work being done by Yard 15, the SDF-Navy took a keen interest in the project as well as the Medical Faculty of the University of Wembury, who assisted in planning the hospital wings.
In May 2017, the first vessel was laid down.

Pricing
One Hope-class Hospital Vessel: 100 million NSD.
One Hope-class Hospital Vessel, fully equipped and stocked: 400 million NSD.

The ChiCajun-II-class Amphibious Assault Ship is is a vessel developed and suited for amphibious operations and their support, as well as Rapid Force Deployment of a brigade-sized force based on a request for a prototype by the navy of the Armed Republic of Paleocacher.

Design
The ChiCajun-II-class Amphibious Assault Ship is a classical mono-hull design,
The ChiCajun-II-class Amphibious Assault Ship is built with stealth-measures in mind, but not a dedicated stealth-vessel. With inclined flanks to bounce off radar waves bouncing off the hull into the air above and with anchorhouses and stairwells placed inside, the ChiCajun-II-class Amphibious Assault Ship appears like a far smaller vessel. The thermal and acoustic signatures are, due to the ChiCajun-II-class Amphibious Assault Ship's nature as a nuclear powered vessel, unmasked.

Propulsion
The ChiCajun-II-class Amphibious Assault Ship is powered by a Ga-17 Mark II Nuclear Reactor, the same as are used on the Beag-class Aircraft Carrier, providing 75 megawatts of energy, which is used to power all systems aboard the ship, be it the coffeemaker or the engines. The Ga-17 Mark II is a reliable and proven design, which work like nuclear reactors on land do: Heating water to produce steam, which power steam turbines to produce electrical power. The feed water, which is turned to steam, is pumped aboard, demineralised, and used.
90% enriched Uranium Fuel Cells need to be loaded as power cells. We also recommend employing experienced nuclear reactor technicians.
The vessel itself is driven by two azimuth thrusters with controllable pitch propellers, providing more manoeuvrability and power efficiency while being rather easy to maintain. A bow thruster provides additional manoeuvrability, especially while docking.

Electronic Warfare and Decoys
The ChiCajun-II-class Amphibious Assault Ship is equipped with a variety of systems for Electronic Warfare and with decoys to protect itself against the enemy without use of the own weapons suite.
Core of these capabilities are the suites for Electronic Countermeasures and Electronic Support Measures, ECM and ESM respectively. ECM provides the ability to deceive and trick enemy means of detection, like radar and sonar, active measures confusing the enemy's sensors, while passive systems for example jam the guidance systems of enemy missiles.
ESM, meanwhile, detect, intercept, identify, locate, record and analyze sources of radiated electromagnetic energy, for example radar, for primarily threat recognition and in secondary functions for example intelligence information. Provided with this data, both the ECM and the MASS (see below) can work more effectively against enemy missiles, as well as the commander making the necessary decisions.
The ChiCajun-II-class Amphibious Assault Ship is also equipped with a Multi-Ammunition Softkill System. The MASS is connected to the sensor systems, mainly radar, and uses the data to launch radar decoys operating on all relevant wavelengths of the electromagnetic spectrum, confusing advanced, sensor-guided missiles. It can either be operated by a person or operate autonomously.
For less advanced missiles, the ChiCajun-II-class Amphibious Assault Ship is equipped with two launchers for chaffs, which confuse less advanced radar-guided missiles and the radars aboard the enemy vessels.
For defence against torpedoes, the ChiCajun-II-class Amphibious Assault Ship is equipped with a Torpedo Decoy Launcher, working effectively against the acoustic-homing variety by sending out a loud decoy to distract the guidance systems.

Sensors and Processing Systems
Technical Data - Radar Suite
2x Nuacht N-12 Mark II Air/Surface Search Radars (Multi Function)
    Bands: X
    Range: 400 km
    Height of target: 9.5 km
    Power: 100 kW
1x Nuacht N-4 Navigation Radar
2x Nuacht N-38 Fire Control Radars
The ChiCajun-II-class Amphibious Assault Ship is equipped with a multitude of sensor systems, chiefly amongst them two capable and proven Nuacht N-12 Mark II Air/Surface Search Radars. These radars, used on most of SDY's military vessels in one form or the other, are capable of tracking a target 400 kilometres away and of tracking 400 targets at the same time, be they on the surface, in the air or anywhere inbetween.
Their most important use is to detect any incoming threat and to use the collected data to act against it with the own weapons systems, or, by coordinating via a battlescape network, have other vessels act against it.
While the N-12 provides information about where the target is, the Nuacht N-38 Fire Control Radar provides data about where the own shells are, in particular those of the Ceantar C-44 Mark II 40mm AA-guns (see below), in order to adjust the own firing solutions.
For finding the own way, the ChiCajun-II-class Amphibious Assault Ship carried a Nuacht N-4 Navigation Radar.
Of greatest importance to the most important task of the ChiCajun-II-class Amphibious Assault Ship, the landing and coordinating amphibious troops, is the Tactical Air Navigation System fitted onto the vessel. The TACAN, a Nuacht N-103 Mark III, is a system used to provide aircraft equipped for operating with such a system with information about the own bearing and distance, relative to a surface station, in this case the ChiCajun-II-class Amphibious Assault Ship. This provides aircraft with precise information as to where they are and where they are needed.
Although both Nuacht Limited and other companies are working on a space-based replacement system akin to GPS, the importance of the non-space-based system is not to be underestimated, mainly because ASAT-Missiles are projected to become an important thing.

Artio Battlescape Network Mark III-C
Another important system for effective operation of the ChiCajun-II-class Amphibious Assault Ship is the Artio Battlescape Network Mark III-C. Via directed data-transmission, each ship can share data by direct line of sight, around 40 kilometres.
Although this system can be disrupted, albeit with a whole lot of difficulty, no one can listen in. The direct line of sight also requires, that no obstacles are between the transmission stations, which are kept in line by the Type 900. However, this range can be made next to unlimited by hooking up the whole system to a satellite, which can share the data needed without any problems.
Although normal telecommunication satellites can be used for this purpose, Silverport Dockyards Ltd. has made an invitation for bid to a few companies specialized in such things, hoping to be capable of offering a complete system with a specialized satellite by 2018. The Artio can be connected to major Battlescape Network Systems, but we highly recommend reading the manual.

The ChiCajun-II-class Amphibious Assault Ship is equipped with a variety of weapon system, all of them more defensively oriented. Despite being armed for self-defence, the vessel needs to be escorted by other vessels as most of the defensive systems are short-ranged, with the Ceantar C-46 Mark II CIWS-Turrets, which came aboard with the 2018 Upgrade of the Design, scratching the lower limit of medium range.
These C-46 Turrets are the newest development of the ubiquitous 40mm gun, the Ceantar C-44, equipped with its own little targeting and fire control radar. These multi-purpose guns' primary function is air-defence, slinging three-hundred 40 millimetre shells per barrel at the enemy or their missiles, but they can also be used as a defence against small vessels and attack craft. The C-46 is capable of firing high-explosive, armour-piercing, armour-piercing discarding sabot, incendiary and training ammunition.
On the other hand, the ChiCajun-II-class Amphibious Assault Ship has two Ceantar C-84 30mm CIWS at their disposal, one on each broadside, equipped with their own little fire control radars, capable of operating semi-autonomously, six-barrelled gatling guns reliably throwing 30mm shells at every target coming too close for the own comfort.
Additionally, the ChiCajun-II-class Amphibious Assault Ship has four designated balconies, positions on the superstructure capable of being used as positions for heavy weapons teams or additional weapons or remote weapons stations.

Troop Complement and Well Deck

Displacement: 250 tons
Length: 35 metres
Beam: 6.8 metres
Draught: 0.8 metres to 1.3 metres (full load)

The ChiCajun-II-class Amphibious Assault Ship is equipped to take aboard a force of 2,753 marines, plus their equipment and initial landing supplies, as well as the provisions to bring ashore a sizeable force using the capabilities of the Well Deck. Said Well Deck is measured 89.4 by 25.6 metres, located at the stern of the ChiCajun-II-class Amphibious Assault Ship, capable of carrying up to six Landing Craft the size of the Pattern 502. These can be loaded by moving equipment of the vehicle and supply decks into the appropriate elevators and moving them to the Well Deck. The Well Deck can be flooded.
Additionally, the ChiCajun-II-class Amphibious Assault Ship can carry up to four additional landing craft the size of the Pattern 502 on davits in the superstructure.

History
Ever since its establishment, the SDF always had the problem of only partially being able to move troops and equipment to and from the Northern Islands and the Archipelago to and from the Mainland. While freighters were fine for most uses of the SDF, the disastrous results of the Halfblakistani Expedition made the SDF aware, that they needed a way to transport troops safely and with sufficient speed.
While SDY began to draw up plans, the SDF decided to acquire three units of the Sealgaire-class Helicopter Carrier, which answered their request for proposal better then the so-called Pattern 120.
Pattern 120 was a gargantuan amphibious assault ship, planned to take an entire regiment and enough supplies to supply a small country's army for fighting operations – and was shelved.
A few years later, the navy of the Armed Republic of Paleocacher requested an amphibious assault ship for rapid force deployment, capable of carrying a brigade and landing a battalion-sized force ashore – while the original concept of the Navy of Paleocacher was unworkable, the forelady of Yard 15 made a counter-proposal within the ranges and capabilities of the old Pattern 120 without remembering it.
With a few modifications, for example fitting a nuclear reactor, and updates especially to the sensor suite, the development was continued and renamed, by specifications of the order, ChiCajun-II-class Amphibious Assault Ship.
In late 2018, SDY replaced the design's Ceantar C-44 Mark II 40mm AA-guns with two Ceantar C-46 Mark II CIWS-Turrets, which debuted on the Labhandar-class Air Defence Corvette. A refit of already finished vessels is not planned so far.

Pattern 502 Landing Craft

Postby The Selkie » Fri Jun 02, 2017 11:37 pm

Technical Data
Type: RoRo Landing Craft
Displacement: 250 tons
Length: 35 metres
Beam: 6.8 metres
Draught (under full load):
    0.8 metres, front
    1.3 metres, aft
Capacity: 65 tons
Complement: 6 sailors
Armament: 2 remote weapons stations
The Pattern 502 Landing Craft is a boat designed by Silverport Dockyard's Subsidiary Bád Industries for usage by amphibious vessels, designed to bring vehicles (both wheeled and tracked), infantry and supplies from the vessels to shore easily. The Pattern 502 Landing Craft can also be used for normal ferry operations, including for civilian purposes.

Design
The Pattern 502 Landing Craft is a 35 metres long and 6.8 metres wide landing craft with a draught of 0.8 metres at the bow and 1.3 metres at the aft when under full load of 65 tons. The craft displaces 250 tons when empty. Build with a welded steel hull as a flat-bottomed boat with a two chine hull it rides on the water, not in it, making it more stable in calm water and allowing for a larger cargo capacity. This special method of construction permits also for operations in sea states 5 to 6 and on rivers, the latter also due to its low draught.
The Pattern 502 Landing Craft is constructed for Roll-on/Roll-off operations, both with a strong bow ramp capable of handling an MBT of up to 60 tons and a stern ramp, which can be hooked into other Pattern 502 Landing Craft's bows in order to create a bridge or pier, as well as the small bridge set aside to starboard. This also allows for easy modification into different roles, from first aid station over repair workshop, ferry and many others.
Powered by two diesel generators, each providing 500 kW of power, powering all systems aboard the vessel, from the engines to the hydraulics of the bow ramp to the stove of the cook, the Pattern 502 Landing Craft is pushed forward by two mixed flow waterjets, allowing for both operations close to shore, as the waterjets are protected from debris and the ground, and for more efficient usage of power. The two generators are placed in two different engine rooms.
The crew of six is housed under the bridge, where a small kitchen is built in, with a small washing room to the side. The bridge itself is covered and lightly armoured, capable of withstanding small arms fire. Housed on its roof is a small navigation radar, the antennas for both GPS and radio, while the analogue navigation equipment is stored on the bridge.
For self-defence, the Pattern 502 Landing Craft is armed with two remote weapons stations, which can be armed with heavy weapons up to heavy machine guns and grenade machine guns. Control stations for both are on the bridge.
To get itself back into the water, the Pattern 502 Landing Craft has an anchor of half a ton, attached to a towing cable, which is mounted onto a winch with a pulling force of twelve tons, enabling the Pattern 502 to pull itself back into deeper waters in order to use the own engines again.

History
The Pattern 502 Landing Craft is the result of a development process starting with the conception of the Sealgaire-class Helicopter Carrier and its well deck, which made the need for landing craft apparent. The SDF, ever since its inception, only had the need for landing craft once, during the Second Vellenge War in the 1983, which was, mainly due to a lack of these vessels and experience in operating them, circumvented.
Troops on the Northern Islands, on the Archipelago and on the other islands were always landed, replaced and supplied by other means, not Landing Craft, even in the most remote areas of these regions. And with the experiences of the Halfblakistani Intervention still in mind, the shipyard went to work.
So, the Bád Industries, armed with two rough outlines of what was needed and how it should operate, made by both SDY and the SDF and contradicting each other in some places, began to work. They drew from, coincidentally, the First Vellenge War in the early 18th century, where the landing Selkie utilized a type of craft, which might as well be called a distant ancestor of the Pattern 502, landing both troops, equipment and horses to capture Fort Scogiera in one, swift strike, beginning the war in 1712.
While none of these craft survived the three centuries since then, their plans certainly did and served as an inspiration, as Bád Industries would later claim – in truth, Pattern 500 was build, a group of three replicas of the landing craft in question, with Pattern 501 being a more updated version, a demonstration and testbed vessel for what they had in mind, the development process partially being covered by the University of Wembury in order to save money.
From these, Pattern 502 was developed, with the first prototype being launched and tested starting January 2017 and the SDF being equipped by June. During that testing phase, the Bolcán Island Storm ravaged a small island and the prototype was deployed along with a few other vessels of SDY's Yard Fleet to aid with the relief efforts – and performed admirably, ferrying supplies from freighters to shore with relative ease before landing and being converted to a field hospital.
A week later, she returned home with a few scratches, but with her trials completed.

Pricing
One Pattern 502 Landing Craft: 950,000 NSD.

Taistealaí-class Mainline Ferry

Postby The Selkie » Fri Jun 02, 2017 11:39 pm

Technical Data
Displacement: 7,800 long tons
Length: 130.7 metres
Beam: 26 metres
Draught: 7.2 metres
Propulsion:
    Integrated Electric Propulsion,
    two Diesel Generators, 3,500 kW per generator,
    2 waterjets
Speed: 18 knots (33.3 km/h)
Complement: 56
Sensors and Processing Systems:
    Navigation Radar, Satellite Uplink,
    GPS, Onboard Entertainment Network
Aircraft Installations: Helipad
    Converted from Tent Area
Capacity: 500 passengers, 135 automobiles
The Taistealaí-class Mainline Ferry is a small vessel developed and build by Silverport Dockyards Limited to act as a Roll-on/Roll-off Ferry on short-range routes, carrying both passengers and their vehicles from places to other places.
Equipped for overnight stays, the Taistealaí-class Mainline Ferry is not exactly a cruise liner, but it still offers some amenities to make the trip a little bit more comfortable.

The term taistealaí means traveller.

Design
The Taistealaí-class Mainline Ferry is a classical monohull design with a double hull and strengthened frames, which allow the vessels of this class to operate in ice-riddled waters, even break light ice sheets, but should not be used as icebreakers. The vessel is 130.7 metres long, has a beam of 26 metres, the superstructure spanning the whole beam of the vessel, and a draught of 7.2 metres, displacing 7,800 long tons unloaded, capable of loading 135 automobiles of an average length of 6 metres and 500 passengers in 104 staterooms and on two tent areas. The vessel is equipped with a GPS Uplink and a small navigation radar.
If the need should arise, the Taistealaí-class Mainline Ferry can be used as a disaster relief vessel, acting as a seaborne hospital and supply ship. To that end, the tent areas can be transformed to helicopter landing pads for light transport helicopter and the ramps leading into the inside of the Main Deck can be extended to the surface itself in order to take aboard people from lifeboats or other small vessels.
Of the seven decks of the vessel, five are accessible to passengers, with the lower two being off limits as these contain the inner workings of the vessel, from the engine rooms to other machinery to storage rooms and the small medical bay onboard. The other five are the Main Deck, the Upper Deck, the Cabin Deck, the Boat Deck and the Bridge Deck:
    The Main Deck serves as the main vehicle stowage, one vehicle deck running the entire length of the vessel with a car elevator and three smaller elevators leading upwards.
    The Upper Deck contains half of the staterooms, namely the four-berth rooms, and the berthing for the crew, as well as office space close to the bow, more then enough for all office-related needs the Taistealaí-class Mainline Ferry may encounter. In the middle, above the keel, there is a second, smaller vehicle storage, accessible by the elevator.
    The aft-half of the Cabin Deck is taken up by the two-berth staterooms, as well as the Lower Tent Area, an open area dedicated to those travellers, who were unwilling or unable to pay for a stateroom and instead camped out in the open. The bow-half of that deck has a small movie lounge and a larger observation lounge, which offers a beautiful view of the surrounding waters.
    The Boat Deck has a second, larger observation lounge, which is separated into four different secotrs, a children's lounge with play area, a writing lounge and a silent lounge, as well as a forward lounge overlooking the bow. Both a snack bar and the Dining Room are on this deck as well, the kitchen being between them. Close to the elevator, a room with large washing machines allows for cleaning own clothing if it is so desired.
    Above that is the Bridge Deck, containing the vessel's bridge at the bow and a few technical facilities, including the radio room, a solarium and a second open tent area.
The Taistealaí-class Mainline Ferry is optimized for Roll-on/Roll-off Operations, with three ramps leading onto the Main Deck, one on port, one on starboard and one aft.

Amenities
The Taistealaí-class Mainline Ferry comes with a number of amenities for both crew and passengers, none of which have anything to do with the staterooms' comfort.
Of the 101 staterooms, 45 have four berths, 56 two berths and three are accessible for wheelchairs, all of them having a small stall with shower and toilet, barely large enough for a fully grown man to turn around in. The cabins include one or two bunk beds, a cabinet and a window, which can be opened.
Besides the lounges, the large amenities include a small cinema, a snack bar and a larger Dining Room, which is either a real restaurant or a cafeteria style dining room with nothing keeping an operator to furnish one of the observation lounges with tables as dining areas, we recommend the one on the Boat Deck for that purpose.
Several WLAN Access Points are scattered over the vessel, allowing for passengers to access the internet by the way of a satellite uplink, the same also connecting the vessel to the telephone network, radio and television, the uplink physically separated from the ship's computers. For those, who like to surf onboard, the Taistealaí-class Mainline Ferry is equipped with an OEN, an Onboard Entertainment Network, allowing for chatting, network multiplayer games and many other things, the system itself being a distant cousin of the Artio Battlescape Network used on most of SDY's military vessels.
For passengers preferring to stay outdoors, two tent areas allow for a safe and stable outdoors camping platform on the sea with two pairs of shower stalls and toilets set aside for the campers.

Propulsion
The Taistealaí-class Mainline Ferry is powered by two diesel generators, each providing 3,500 kW of power. This power is used to operate all the systems onboard, including the engines, in a system known as Integrated Electric Propulsion, IEP for short, which reduces the need for gearboxes to nothingness, making maintenance cheaper and easier to all involved. The generators are related to the generators used onboard the Cineál-class Yacht and are, like them, build and installed with reduced noise pollution in mind, resting them on shock absorbers.
Propulsion is provided by two mixed flow waterjet engines, highly efficient both in output and power consumption, accelerating the vessel to up to 18 knots. Due to their nature as waterjets, the engines are protected from ice and debris, with an additional heater inside the engine making acting against iced over engines possible without someone diving into them. Manoeuvrability is increased by these engines being mixed-flow, which allows for reversing the thrust on one or both waterjets to help with turning or even reversing into the dock – without needing tugboats.

History
The Taistealaí-class Mainline Ferry is a relatively old design, from the late 60s, which had been developed by one of the predecessors of SDY, the Ríchathaoir Shipyard Company, which saw in these vessels a chance to shake off the Yard Crisis, which troubled so many of Silverport's yards – it didn't really help, the company went bankrupt in 1969, as the international market saw no need for the Taistealaí-class Mainline Ferry, and the production rights went back to the engineering office responsible for it, the Caillte Maritime Solutions Engineering Office of Wembury. With Fynn Caillte of the Tribe of Cork, the son of the engineer responsible for the Taistealaí-class Mainline Ferry and husband of SDY's founder's daughter, today's CEO Nora Cathlong of the Tribe of Cork, the plans went into the possession of SDY as part of his inheritance in 1993. Back then, no one saw the need to offer or build such a vessel and the blueprints went into storage.
In late 2016, in correlation with an unofficial request by a customer, SDY began to look for old plans for ferries including vehicle ferries, stumbling across the Taistealaí-class Mainline Ferry – in the words of Yard 15's forelady, funnily enough Fynn Caillte's daughter: “With a few upgrades here and there that punt could finally go to sea!”
Until early 2017, SDY used a small part of Yard 15's resources to update the Taistealaí-class Mainline Ferry, bringing to old design into today's form, especially working on the engine and propulsion and the electronic systems. As the Selkie have little use for car ferries, only a handful are operated by the Selkie, two of which will be Taistealaí-class Mainline Ferries in the future, both planned to replace two old ferries trafficking to and from the Northern Islands.
In June 2017, the Taistealaí-class Mainline Ferry became one of the very few vessels of SDY's production, for which the Domestic Production Rights, or DPRs for short, were offered to any customer.

Pricing
One Taistealaí-class Mainline Ferry: 18 million NSD.
Domestic Production Rights for the Taistealaí-class Mainline Ferry: 1.8 billion NSD.

The Gabhdán-class Fast Combat Replenishment Ship is the result of the SDF-Navy realizing, that they needed a fast vessel for supply purposes to keep pace with other fast vessels and evolving combat situations worldwide, including the replenishment of troops ashore, if the need should arise, also capable of acting as a command and control vessel for squadrons of smaller vessels, like Fast Attack Craft.

The term gabhdán means either a container or a gulliable person.

Design
The Gabhdán-class Fast Combat Replenishment Ship is a classical monohull-design built in accordance with military specifications, contrary to other replenishment ships, which are basically overhyped freighter designs. Vital areas, for example the bridge and engine rooms, are armoured with light Kevlar Splinter Plating. Constructed with a bow piercing the waves like a hot knife does through butter, the Gabhdán-class Fast Combat Replenishment Ship reaches higher speeds and more economic operation then similarly sized vessels.
With a length of 225.5 metres and a beam of 26.8 metres, the vesssel has a displacement of 30,500 tons full load, 18,000 tons standard, and a draught of 8.3 metres when fully loaded. The Gabhdán-class Fast Combat Replenishment Ship can be loaded with up to 10,000 tons of fuel oil of different kinds, including fuel for jets, 500 tons of fresh water and up to 2,000 tons of cargo and ammunition of various kinds. For more fresh water, the Gabhdán-class Fast Combat Replenishment Ship carries a water-purification plant, which recycles old water and uses sea water to produce drinking water.

For loading and unloading cargo, the Gabhdán-class Fast Combat Replenishment Ship is equipped with four light cranes and two heavy cranes, four lines for replenishment of other vessels with fluids, for example fuel, two each on port and starboard and capable of extending up to twenty metres.
Of the cranes, the two heave ones are aligned with the keel, capable of extending 25 metres with a loading capacity of 50 tons, while the lighter ones are at the side of the main cargo hold, two each on port and starboard, capable of extending 15 metres with a maximum load of 15 tons, including, but not limited to, the lines for fluid replenishment. The cranes can safely operate and be operated in sea state 5, the fluid lines in sea state 6, although we don't recommend that.
Additionally, the Gabhdán-class Fast Combat Replenishment Ship carries a hospital with 150 beds, an intensive care unit with ten beds included, and two small operating theatres, which allow for the same treatment as a normal hospital on shore. The vessel's interior itself is fully protected against the onslaught of nuclear, chemical and biological weapons, including storage rooms for gas suits, airlocks and other NBC-protection equipment. This also allows for operations in more frigid environments.

Propulsion
The Gabhdán-class Fast Combat Replenishment Ship is powered by three Diesel generators, which, in an arrangement known as Integrated Electrical Propulsion, provide power for both the ship's electrical systems, like radars or coffee makers, and the engines, thus saving space, eliminating the need for costly gearboxes and generally lowering the operating costs of the vessel. The generators, two in one engine room near the aft, one in a smaller engine room near the front, produce 97,000 kW of electricity, one of them being enough to power the basic systems of the vessel in case of general failure of the other two generators.
This amount of power suffices to accelerate the vessel to 30 knots, or 55.6 kilometres per hours, while allowing for a range of 8,000 nautical miles, or 14,800 kilometres at a cruising speed of 18 knots. This range can be extended considerably should the fuel in the tanks intended for replenishment be used by the vessel itself.
The exhaust fumes of these diesel generators are funnelled along the vessel and exhausted through one main smokestack, when they have cooled down considerably, thus reducing the vessel's thermal signature. For reducing the acoustic signature, the generators are rested on shock absorbers.

Electronic Warfare and Decoys
The Gabhdán-class Fast Combat Replenishment Ship is equipped with full suites for Electronic Counter Measures, Electronic Support Measures and Electronic Counter-Counter Measures, as well as a number of other, passive defensive systems.
Electronic Countermeasures, or ECM for short, are used to deceive and trick enemy means of detection and ultimately not having a guided missile slam into the ship's side. Be they sonar decoys or radar jammers (Rasberry Jammers is the system we usually use), active ECM measures confuse the enemy's sensors, while passive measures include for example the jamming of the guidance systems of enemy missiles.
Electronic Support Measures meanwhile detect, intercept, identify, locate, record and analyze sources of radiated electromagnetic energy (for example radar) for threat recognition and other purposes, amongst them intelligence information. With these information, a commander can make the tactical and, if necessary, strategic decisions needed. It also provides the means necessary to gather information about the Electronic Warfare Systems of the enemy either in order to avoid an attack or to attack more effectively.
With Electronic Protection (EP), or Electronic counter-countermeasures (ECCM), the ship is hardened against every kind of electronic attack, for example against scrambling and jamming. This allows to attack the enemy even when he feels safe with his jammers in place and activated.

In addition to that, for those enemies or their missiles, which come too close, the Gabhdán-class Fast Combat Replenishment Ship is equipped with a Multi-Ammunition Softkill System, MASS for short. The system connected to the sensor systems, mainly radar, and uses the data to launch radar decoys operating on all relevant wavelengths of the electromagnetic spectrum, confusing advanced, sensor-guided missiles. It can either be operated by a person or operate autonomously.
For less advanced, heat-seeking missiles, the Gabhdán-class Fast Combat Replenishment Ship is equipped with two launchers for chaffs, which will confuse heat seekers and divert them from the vessel.
In case of submarine attack, the Gabhdán-class Fast Combat Replenishment Ship carries a launcher for torpedo decoys.

Sensors and Processing Systems
Technical Data
2x Nuacht N-12 Mark II Air/Surface Search Radars (Multi Function)
    Bands: X
    Range: 400 km
    Height of target: 9.5 km
    Power: 100 kW
Nuacht N-4 Navigation Radar
The Gabhdán-class Fast Combat Replenishment Ship is equipped with several radars, both for finding the enemy and finding the own way. Primarily amongst them are two Nuacht N-12 Mark II Air/Surface Search Radars, multi-function radars operating on X-Band to search for and detect and track up to 350 targets at a range of up to 400 kilometres and a height of up to 9.5 kilometres, also looking up their IFF-Identification. These radars can also double as air-traffic control radars, navigation radars and fire-control radars.
In addition to that, the Gabhdán-class Fast Combat Replenishment Ship carries a Nuacht N-4 Navigation Radar.
For warnings against radar-locks on the own vessel, the ship is equipped with a suite of highly advanced Radar Warning Receivers, warning in case of radar locks, for example by enemy radar guided missiles and thus allowing for countermeasures.
As a measure against submarines and other botherings from beneath the surface, the Gabhdán-class Fast Combat Replenishment Ship is equipped with a bow-mounted sonar.

The Type 900 Datalink is a system for Duplex Communication in both directions in real time, processing said data in real time as well. Not only sensors and weapons are connected by this system, but virtually everything onboard the ship, from consoles on the bridge to the mobile coffee maker by the helipad. Personal Computers and gaming devices of the crew use another system, utilizing a satellite uplink and being diconnected from the Datalink in every way, shape and form imagineable.
To exemplify the processing power of the Type 900 Datalink: When the first prototype of the Type 900 was supposed to be tested, the corresponding department in Laclan hosted a LAN-party with roundabout ten thousand participants (4,157 at height) playing 25 different games - with the 'Local Area Network' reaching across the entirety of the Free Lands with no lags whatsoever.

Artio Battlescape Network Mark III-C
Another important system for effective operation of the Beag-class Aircraft Carrier is the Artio Battlescape Network Mark III-C. Via directed data-transmission, each ship can share data by direct line of sight, around 40 kilometres.
Although this system can be disrupted, albeit with a whole lot of difficulty, no one can listen in. The direct line of sight also requires, that no obstacles are between the transmission stations, which are kept in line by the Type 900. However, this range can be made next to unlimited by hooking up the whole system to a satellite, which can share the data needed without any problems.
Although normal telecommunication satellites can be used for this purpose, Silverport Dockyards Ltd. has made an invitation for bid to a few companies specialized in such things, hoping to be capable of offering a complete system with a specialized satellite by 2018. The Artio can be connected to major Battlescape Network Systems, but we highly recommend reading the manual.

Most of the armament of the Gabhdán-class Fast Combat Replenishment Ship serves defensive purposes, with the primary defensive load against enemy missiles and aircraft resting on the shoulders of the four Ceantar C-84 Mark II CIWS, which are mounted two on either side of the vessel and capable of covering all angles of approach by enemy missiles with at least one gun, in most cases two. As CIWS, these are the weapon of last resort against incoming missiles, ECM and decoys being primary means. The guns can operate either autonomously, which we recommend, or be controlled manually, both of which is possible due to the C-84 Mark II having its own targetting radar and fire control mechanisms.
The weapon suite is completed by two Ceantar C-44 Mark II 40mm AA-guns, although the term AA-gun is a slight misnomer: While the Mark I was indeed a dedicated AA-gun, the Mark II is a multi-purpose gun, capable of acting against targets both in the air, on the surface and, when in range, on shore. These two guns, one on either side of the vessel between the small cranes, is designed to be controlled by external fire control systems, linked to the radars via the Type 400 Datalink, which provides the data needed for firing adjustments. While that can be done automatically, the gun can also be operated by a gunner using the mounted camera as a 'scope'.
To support the hunt for submarines, the vessel carries two Gráinneog G-321 Mark II Hedgehogs, which are capable of launching the Tormán Mark I shells: Fifteen shells, rocket launched into the general direction of the enemy submarine, each of them carrying a small torpedo as well, which passive acoustically homes into the enemy submarine, penetrating its pressure hull with their payload of twenty kilograms of high explosives - one would be troublesome, two or more would be devastating. Both of them are mounted at the sides of the forward superstructure, one port, one starboard.
Additionally, the Gabhdán-class Fast Combat Replenishment Ship has six 'balconies', positions on the superstructure designed for mounting heavy machine guns or SDY-Gabha SG-1 Mark III autocannons (which will not be included into the normal delivery). Closeby, within the superstructure, are six small rooms with numberpads, which can be used as weapons lockers for the weapons to be used from these positions, in addition to the larger armory in the aft superstructure.

Aviation Facilities
The Gabhdán-class Fast Combat Replenishment Ship comes with a flight deck for two medium-sized helicopters and a hangar for up to five, including a smaller side-workshop for the repair and maintenance of helicopter drones. The flight deck itself is rated safe for vectored-thrust VTOLs.
The command systems for drones, much akin to the ones used aboard the Faoileán-class Drone Carrier, are placed in a seperate room behind the bridge. This allows the vessel to take command of drones patrolling and operating in the area, not only the own, but also the ones launched from further away. The vessel is not equipped to launch or recover fixed-wing drones.

History
The Gabhdán-class Fast Combat Replenishment Ship is a design older then the more contemporary Port Hackburry-class Fleet Oiler. In the early 2000s, SDY began with a design study for a fleet replenishment ship for the SDF-Navy, on their request, to enhance the range of the vessels used by the SDF-Navy and thus enlargening the patrol radius of the vessels in question. At the time, it was known as the Pattern 996 Replenishment Ship.
That project was soon abandoned by the SDF, Silverport Dockyards Limited shelving the plans for future references - that future came in 2012, in Marley Bay, when units of the SDF-Navy went into combat during the Halfblakistani Intervention. Many lessons were taught to the SDF-Navy that day, one of which was the esseential role of larger and more capable support ships. The SDF-Navy didn't have any with them due to those, which the Navy had, simply being incapable of operating in a combat environment.
It is doubtful, that the SDF-Navy would have fared any better, if several of the Pattern 996 Replenishment Ships would have been present, but it wouldn't have hurt either way, these vessels enhancing the combat radius of especially the Fast Attack Craft, which played a vital role in breaking out of the pickle the SDF found itself in. Many of the FACs used in that battle had to be taken under tow during the return trip, which had been quite dangerous.
So, after the battle, the SDF-Navy went ahead and began a large-scale modernization, one result being the Gabhdán-class Fast Combat Replenishment Ship, the unearthed, updated and finished design of the Pattern 996 - the Gabhdán herself being built as a testbed vessel by and for SDY.
The SDF-Navy has ordered ten of these vessels to replace the Sciath-class Corvettes leading the Fast Gunboat Squadrons, read the FAC-Squadrons, and to assign one of them to each of the Sealgaire-class Helicopter Carriers.

The Creachadóir-class Anti-Submarine Corvette, or Predator-class Anti-Submarine Corvette for the international market, is a small and relatively cheap ASW-corvette developed by SDY for export to smaller navies as a viable tool in anti-submarine warfare, or for larger navies as a handy small vessel to conduct ASW-patrols in the own waters. The Creachadóir-class Anti-Submarine Corvette is designed for both active submarine hunting as well as escorting both trade convoys and larger vessels and fleet groups.

The term creachadóir means predator, as in a predatory animal, hence the name for the international market.

Design
The Creachadóir-class Anti-Submarine Corvette is a classical monohull-design, displacing 1,050 tons at standard load, 1,200 tons at maximum load. The vessel is 81.68 metres long, with a beam of 9.8 metres and a draught of 3 metres at standard load. This allows for operations from nearly every harbour in the world, capable of operations both in Blue and Brown Waters, high-seas and coastal areas.
With a range of 3,000 nautical miles at 14 knots, or 5,600 kilometres at 26 kilometres per hour, and a maximum speed of 30 knots, 55.5 kilometres per hour, the Creachadóir-class Anti-Submarine Corvette is capable of hunting down enemy submarines, as well as keeping pace with most warships and trading vessels.

As with most of the newer vessels of SDY, and nearly all military vessels of SDY, the Creachadóir-class Anti-Submarine Corvette is build with stealth measures in mind, but no dedicated stealth vessel. Inclined flanks bounce off radar beams into the unknown, away from the receiver, while parts of the superstructure, such as the anchorhouse and stairwells, are placed inside, further reducing the radar cross-section to that of a far smaller craft.
The thermal signature is reduced by the exhaust gases being channelled through smaller pipes to cool off before being released through three small exhausts, making the vessel's thermal signature smaller. The producers of that exhaust, the diesel generators, are rested on shock absorbers, which reduce the acoustic signature considerably, which helps with both not being detected by enemy acoustic detection measures and detecting enemy acoustic signatures, for example from submarines.
The Creachadóir-class Anti-Submarine Corvette is built using non-magnetic steel.

For Comparison: Medium-sized Helicopter Drone
Length: 4.5 metres
Rotor Diameter: 5.2 metres
Wingspan: 2 metres
Height: 2 metres
The Creachadóir-class Anti-Submarine Corvette can not carry or support a helicopter, but has a small flight deck for medium sized helicopter-drones, as well as a hangar to maintain and store them. Additionally, a control room for helicopter drones is placed near the bridge, using a system and installation bearing striking resemblance to the ones used aboard the Faoileán-class Drone Carrier and with similar capabilities (however, the Creachadóir-class Anti-Submarine Corvette can not launch or recover fixed wing drones).

Propulsion
The Creachadóir-class Anti-Submarine Corvette is powered by three diesel generators, which provide 4,000 kW each, the same generators as onboard the Spéirling-class Fast Attack Craft. These generators provide power for everything aboard the vessel, be it the radars, the engines or the coffee makers, arranged in a dispersed fashion: Two generators are in the main generator room aft, while the third one is close to the bow in a separate engine room. This engine arrangement, called Independent Electric Propulsion or IEP for short, reduces maintenance cost considerably, as gearboxes and their needs of maintenance are simply not necessary, as well as all the power aboard being provided by one system.
The Creachadóir-class Anti-Submarine Corvette is capable of limping back to harbour on only one of these generators, if need should arise. Noise interference and vibrations from the generators are low as well, mainly due to the stealth measures taken: The shock absorbers not only reduce the noise the vessel makes, they also add to crew comfort by eliminating this source of noise almost completely.
Two water jets, or more technical pump jets, propel the vessel forward with a maximum speed of 30 knots or 55.5 kilometres per hour. Although a bit more expensive then conventional propellers, the water jets are both more silent and the blades themselves are better protected against debris and other stuff floating underwater, as well as more silent. Reversing is done by the addition of a reversing bucket, adding to the manoeuvrability of the vessel, while manoeuvring itself is handles with the water jets themselves via thrust vectoring. This also allows for higher speeds during heavier sea states.

Electronic Warfare and Decoys
The Creachadóir-class Anti-Submarine Corvette is equipped with an arrangement of systems for Electronic Warfare and decoys to defend itself against the enemy without bringing the weapons to bear, the first layer in the defence of every warship.
Core of these systems are both the ECM-Suite and the Multi-Ammunition Softkill System, MASS for short, acting against above-surface threats. The ECM-Suite provides the capability for Electronic Countermeasures, meaning capabilities to deceive and trick enemy means of detection and ultimately not having a guided missile slam into the ship's side. With radar jammers (Rasberry Jammers is the system we usually use), active ECM measures confuse the enemy's radars, while passive measures include for example the jamming of the guidance systems of enemy missiles.
The MASS is connected to the sensor systems, mainly radar, and uses the data to launch radar decoys operating on all relevant wavelengths of the electromagnetic spectrum, confusing advanced, sensor-guided missiles. It can either be operated by a person or operate autonomously.
For the defence against torpedoes, the major system is the dispenser for torpedo decoys, which generate a sonar signal, for example engine noise, for the torpedo to lock on instead of the vessel, which is especially effective against passive sonar guided torpedoes. Against active sonar guided torpedoes, the system receives amplifies and sends back the pings send out by active homing torpedoes to confuse the sensors by appearing as a larger vessel. The system, called the Lacha Chluana Mark III, is a fibre-optic towed array on a drum winch to bring the array back to the vessel in case of non-use, and incorporates a small sensor unit to detect incoming torpedoes.

Sensors and Processing Systems
The Creachadóir-class Anti-Submarine Corvette has a wide array of sensors at its disposal in order to detect sub-surface vessels of any kind and size. Core of that suite is a variable-depth sonar, a Nuacht N-81 Mark II VDS, capable of detecting submarines at a distance of up to 150 kilometres at an accuracy of less then 100 metres at maximum range. It is capable of operating in very rough seas as a system for passive and active surveillance 360 degrees around the vessel, analysis of any received signal (and keeping apart, if it is a whale or a submarine), audio output and includes a torpedo alert. Hanging at a single tow line, the Nuacht N-81 Mark II VDS can actively send out pulses while passively detecting sounds made underneath the surface as well in every direction.
The other system for the detection of sub-surface threats is a magnetic anomaly detector – while the system is usually used aboard aircraft, the MAD can also work in a vessel. The principle is rather simple: Every submarine, be it diesel powered or nuclear powered, even when built of non-magnetic materials, creates a magnetic moment displacement, which is detectable. Additionally, every submarine has bits of magnetic materials, be it in diesel engines or nuclear reactors and many other systems, which can be detected.
Technical Data – Radar Suite
1x Nuacht N-12 Mark II Air/Surface Search Radar (Multi Function)
    Bands: X
    Range: 400 km
    Height of target: 9.5 km
    Power: 100 kW
1x Nuacht N-4 Navigation Radar
To detect targets above the surface, the Creachadóir-class Anti-Submarine Corvette is equipped with a proven and capable Nuacht N-12 Mark II Air/Surface Search Radar, an X-Band Radar. This radar, used onboard many of SDY's smaller vessels, like the Scoth-class Corvette, can detect objects from 400 kilometres away, at a maximum height of 9.5 kilometres.
Another radar aboard is the Nuacht N-4 Navigation Radar, used to find the way.
For the detection of incoming radar impulses, for example of enemy warships or aircraft or even incoming radar-guided missiles, the Creachadóir-class Anti-Submarine Corvette is equipped with a Radar Warning Receiver.
Other sensor systems can be employed by the Helicopter-Drones.

The Type 900 Datalink is a system for Duplex Communication in both directions in real time, processing said data in real time as well. Not only sensors and weapons are connected by this system, but virtually everything onboard the ship, from consoles on the bridge to the mobile coffee maker by the helipad. Personal Computers and gaming devices of the crew use another system, utilizing a satellite uplink and being diconnected from the Datalink in every way, shape and form imagineable.
To exemplify the processing power of the Type 900 Datalink: When the first prototype of the Type 900 was supposed to be tested, the corresponding department in Laclan hosted a LAN-party with roundabout ten thousand participants (4,157 at height) playing 25 different games - with the 'Local Area Network' reaching across the entirety of the Free Lands with no lags whatsoever.

Artio Battlescape Network Mark III-C
Another important system for effective operation of the Creachadóir-class Anti-Submarine Corvette is the Artio Battlescape Network Mark III-C. Via directed data-transmission, each ship can share data by direct line of sight, around 40 kilometres.
Although this system can be disrupted, albeit with a whole lot of difficulty, no one can listen in. The direct line of sight also requires, that no obstacles are between the transmission stations, which are kept in line by the Type 900. However, this range can be made next to unlimited by hooking up the whole system to a satellite, which can share the data needed without any problems.
Although normal telecommunication satellites can be used for this purpose, Silverport Dockyards Ltd. has made an invitation for bid to a few companies specialized in such things, hoping to be capable of offering a complete system with a specialized satellite by 2018. The Artio can be connected to all major Battlescape Network Systems, but we highly recommend reading the manual before doing so.

The Creachadóir-class Anti-Submarine Corvette is equipped with a wide array of weapon systems, most of them geared towards the defence of the own vessel and the attack against sub-surface targets.
For attacking targets far above the surface, the Creachadóir-class Anti-Submarine Corvette is equipped with two 30mm CIWS, Ceantar C-84 Mark II, one on starboard, one on port. The C-84 Mark II is equipped with their own little targeting radar, operating fully autonomously against incoming missiles and aircraft coming too close for mutual comfort. This results in said target, usually a missile, being shredded by 30 millimetre bullets.
Mounted on the bow, the Ceantar C-44 Mark II 40mm AA-gun is not only an AA-gun, but also a multi-purpose gun, capable of acting against both surface targets and airborne targets, including missiles (although it is not effective as an auxiliary CIWS). While guns of this type can operate independently with the aid of a fire control radar, the C-44 aboard the Creachadóir-class Anti-Submarine Corvette can use the Nuacht N-12 in that function, but we recommend setting it to manual control and let an operator remote control the gun with the mounted CV-cam as his scope.
Mounted on either side of the superstructure, the Creachadóir-class Anti-Submarine Corvette is equipped with two Gráinneog G-321 Mark II Hedgehogs, capable of firing the Tormán Mark I shells: Fifteen shells are rocket launched into the general direction of the detected enemy submarine, but each of these shells now carries a small torpedo, an passive acoustic homing little weapon optimized for attacking submarines, penetrating their pressure hull quite effectively with 20 kilograms of high explosives. One will only cause problems for sure - two or more are a bit more difficult to handle.
Mounted at the rear on a fixed mount is the longer ranged weapon against submarines, the Feadán Fe-32 Mark II 533mm Quadruple Torpedo Launcher, differing from the Mark I, as it used aboard the Rhiannon-II-class Frigates only by the addition of one barrel. The torpedoes are launched by compressed air, out aft into the sea.
Last, mounted at either side of the torpedo launcher, but definitely not least, are the two rails for mines and depth charges, which can be dropped either manually or using the automated system. Up to 20 normal-sized naval mines can be loaded for each rail within the standard load-out of ammunition.

History
Ever since the invention of the submarine, the question had always been how to counteract them – merciless battles were fought by submarines, both against surface targets and sub-surface targets, for the own survival. With the end of World War II, the famous Wolfpacks made way to independently operating submarines with many roles, from fighting ships to ending the world.
Warfare against submarines, ASW, became more and more important to the planners of navies and wars, both on the defensive and the offensive, and defending against submarines became more and more of an issue. Silverport Dockyards Limited realized that a long time ago: One of the first military designs of SDY, following the Sciath-class Corvette's Construction Contract, was the Práta-class Corvette, a dedicated ASW-Corvette, which was never built, despite being a sound design and a foundation for the Creachadóir-class Anti-Submarine Corvette.
It took a while, the SDF-Navy preferring multi-purpose vessels and SDY not yet exporting in major quantities, until Yard 15 took the matter up again as a side-project - and in early 2017, they presented a design, which became the Creachadóir-class Anti-Submarine Corvette, a vessel primarily for the export to foreign countries.

SDY-Greadtóir 19 Cuaifeach Shipborne Helicopter

Postby The Selkie » Sat Jul 01, 2017 7:38 am

Technical Data
Type: Shipborne Helicopter
Length: 11.5 metres
Height: 5.2 metres
Main rotor diameter: 16 metres
Empty weight: 6.4 tons
Maximum takeoff weight: 12.2 tons
Capacity: 4.2 tons
Powerplant:
    2x Luas L-91 Turboshaft Engines,
    1700 horsepower each
Maximum speed: 275 km/h
Cruise speed: 200 km/h
Range: 1,000 km at cruise speed
Service ceiling: 5,000 metres
Armament: depending on configuration
The SDY-Greadtóir 19 Cuaifeach Shipborne Helicopter is the result if a request for proposals by the SDF to replace the older Fuisce Utility Helicopters of the SDF in service since the late 70s. Developed and built by SDY's subsidiary Greadtóir Limited, which has modified helicopters according to custom specifications since the 90s, and is now, with the Cuaifeach, presenting their first own design.

The term cuaifeach means whirlwind.

Design
The SDY-Greadtóir 19 Cuaifeach Mark I Shipborne Helicopter is a relatively small sized shipborne helicopter with coaxial rotors. The fuselage has a length of 11.5 metres, a height of 5.2 metres and a diameter of the main rotors of 16 metres, although the main rotors can be folded for space-saving.
The Cuaifeach Helicopter has a crew of third, a pilot and a co-pilot, as well as a sonar operator. Up to 4.2 tons of freight can be loaded onboard the Cuaifeach Helicopter, the cabin being lined with folding chairs for up to 16 fully armed soldiers.
Due to its rugged design, the Cuaifeach Helicopter can be used in both tropical and arctic areas and can safely hover in storm force 5 due to a stable auto-pilot and an inertial guidance system connected to it. For operations in arctic areas, the rotor blades can be heated up.
Due to the rotor arrangement, the Cuaifeach Helicopter does not need a tail rotor, thus saving space and reducing the acoustic signature, eliminating the 'slapping'-noise. This rotor arrangement also allows for a more stable flight then single-rotor arrangements, reducing torque - for steering, the rotor blades are pitched, thus creating controlled torque.
For crew and passenger safety, the Cuaifeach Helicopter is equipped with chambers for survival gear and parachutes underneath the crew seats, while both sides of the airframe have containers for air cushions, which are automatically deployed as soon as the helicopter hits the water, thus enabling the crew and passengers to leave the aircraft as it is still above the surface and swim to the emergency inflatable dinghy.

Aiframe
The airframe is constructed as a semi-monocoque fuselage built of corrosion-resistant materials, lightly armoured to resist small arms fire. The cabin has space for pilot and copilot, while the sonar operator sits behind them. A twin-tail provides additional steering power.
The passenger compartment is separated from the crew compartment by a door, the passenger compartment featuring two wide entrances to either side. Provision to mount heavy machine guns are integrated into the sides for a door gunner on either side.
Integrated into the fuselage are the rubber fuel tanks, self-sealing and fire-resistant.
The steering commands are transmitted by triple-redundant fly-by-wire systems based on modular architecture, including dual redundant digital databusses. Data about speed, heading and similar data is displayed digitally on the flight instrument displays, thus not relying on analogue dials and gauges. These displays can also support a pilot helmet with HUD-Capabilities.
The airframe also provides provisions to carry and deploy flares and chaffs for self-defence, two dispensers for each mounted on either side of the fuselage.
Two stubby wings provide provisions to carry external fuel tanks, ammunition, like rocket pods or light anti-ship missiles, or external cargo pods on four hardpoints.

Engines
The engines of the Cuaifeach Helicopter are two Luas L-91 Mark II Turboshaft Engines, a new version of the capable engines which powered the Fuisce Utility Helicopters, providing 1700 horsepower each.
This engine, with a dry weight of 300 kilograms, is a free-turbine turboshaft engine with annual combustors, a single-stage turbine driving the 10 stage all-axial compressor. The engine features a double-redundant Full Authority Digital Engine Control System, or FADEC-System, which is a digital computer, the Engine Control Unit, with the accessories to control all aspects of the engine performance, thus providing maximum efficiency, both concerning power output and fuel efficiency, at any given condition. The L-91 consumes 300 grams of fuel per kilowatts and hour, achieving a maximum power-output of 1,267.7 kilowatts with an minimum air mass flow of 8.9 kilograms per second.
The engines themselves are relatively easy to maintain, although the maintenance of the concentric shaft and the accompanying gearboxes is a bit more complicated.

Sensors
The Cuaifeach Helicopter is equipped with a small radar underneath the cockpit, a magnetic anomaly detector in the tail, a dipping sonar in the back of the fuselage, and a dispenser for sonar buoys between the cockpit and the passengers cabin. The Cuaifeach Helicopter also equipped with a radar-warning receiver, telling the craft, when it is acquired by a radar.
Navigational data is provided by a GPS System, communications by a 16-channel digital communication set with a range of 500 kilometres. The radio is ECM-resistant, making interruptions to the radio traffic not impossible, but considerably harder.

SDY-Greadtóir 19 Cuaifeach Mark I Shipborne AWACS Helicopter
A special modification to the airframe is the SDY-Greadtóir 19 Cuaifeach Mark I Shipborne AWACS Helicopter, a helicopter equipped with a retractable landing gear and a large, foldable antenna of the early warning radar.
The compartment for passengers is taken up by the radar's crew, their processing systems, an Artio Battlescape Network Mark IV-L and the auxilliary power unit providing power for all of that. The radar, a Nuacht N-45 Mark II Planar Array Radar, can detect aircraft at a distance of 150 kilometres, surface vessels from, depending on their size, 100 to 250 kilometres and track up to 75 targets at the same time, relaying their data to a control node, for example a ship, via the aforementioned Artio Battlescape Network. An IFF-System is installed into the radar. If need should arise, the Cuaifeach AWACS Helicopter itself can act as the node, but we do not recommend that.
A helicopter equipped with these modifications can not be modified into any other role. However, the SDY-Greadtóir 19 Cuaifeach Mark I Shipborne AWACS Helicopter retains the capability to detect submarines, but does not have the provisions to fight them.

SDY-Greadtóir 19 Cuaifeach Mark I Shipborne Civilian Helicopter
Another modification is the SDY-Greadtóir 19 Cuaifeach Mark I Shipborne Civilian Helicopter, a demiliterized version of the airframe, lacking the armour, provisions to carry armament, the advanced sensors (like the sonar) and the countermeasures.
In return, the SDY-Greadtóir 19 Cuaifeach Mark I Shipborne Civilian Helicopter is equipped with a sound-proof cabin and cockpit. The cabin can be modified to allow for a more luxurious feeling of flight or for the transport of freight or passengers as a liner.
A more specialized cargo lifter is currently in development.

History
During the 1940s and 1950, the SDF began with trials and subsequently the adoption of helicopters in place of floatplanes aboard its vessels. During that time, the seaplane tender SDFC Faoileán was rebuild as a helicopter carrier, signifying that change.
The change was rather fast, mainly due to the SDF having little in the ways of vessels capable of carrying floatplanes or subsequently helicopters. Over the decades, it became a design requirement for all new SDF-Navy vessels above a certain size to at least be able to support an exceedingly large helicopter.
That trend, increasing size of the helicopters for little to no gain, began to bother the planners of the SDF and with the starting development of the Sealgaire-class Helicopter Carrier, the SDF began to look for a replacement. SDY, developers of the Sealgaire-class, cooperated with several design offices to build the new shipborne helicopters of the SDF, one of which became the Cuaifeach.
With its first flight in late 2015, technical kinks of the Mark 0 and the initial testing aboard vessels of SDY's Yard Fleet being taken care of, the design proved promising. Mark I Prototypes provided relief and aid to Bolcán Island after the severe winter storm in late 2016, a short time later, in early 2017, the SDF ordered production runs.

With the planning of the Sealgaire-class Helicopter Carrier, the SDF also saw the need for an AWACS platform, deciding to adopt the Cuaifeach for that role, ordering the modification of the normal helicopter for that purpose, thus creating the SDY-Greadtóir 19 Cuaifeach Mark I Shipborne AWACS Helicopter.
First flight of that adaptation was in early 2017.
Other options for that role were specially constructed helicopter drones and helicopters, as well as VTOLs, but with logistical constrains in mind, the SDF decided for a modification of the Cuaifeach with its specially developed radar.

Aurelia-class Sailing Yacht

Postby The Selkie » Sat Jul 01, 2017 7:39 am

Technical Data
Displacement: 2,015 tons
Length:
    Overall: 94.05 metres
    At waterline: 73.1 metres
Beam: 14.25 metres
Draft: 3.8 metres
Sail Plan: Three-masted Capall na dTonn
Speed: 14 knots under good conditions
Crew: 14 plus 8 stewards
Passengers: Staterooms for 20 passengers
Decks: 5
The Aurelia-class Sailing Yacht is the result of a request by Prince Damir ibn-Razia for the development and construction of a purely sail-driven yacht for recreational purposes of luxurious proportions. Bád Industries, with involvement of Silverport Dockyards' Yard 15, delivered.

The first vessel of this class, and therefore the namesake, was named after the orderer's daughter, Princess Aurelia bint-Damir of Kyrenaia, a half-Selkie herself.

Design
The Aurelia-class Sailing Yacht is a classic monohull design with a light steel hull and aluminium superstructure. That means, that the vessel in its bare form is light, but sit safely and securely in the water by its own weight, which is added to by a pair of short bilge keels, which provide additional stability, even in heavier waters.
The vessel is overall 94.05 metres long, at waterline 73.1, the reason being a rather large bowsprit, with a beam of 14.25 metres and a draft of 3.8 metres. Under full load, ready for a trip of three weeks, with all staterooms fully manned, the vessel displaces 2,015 tons of water.

Decks

Waterline
Technical Deck
The Aurelia-class Sailing Yacht has five decks, which have different functions and provisions. All decks are connected by an elevator running along the main mast. All decks and rooms are sound-proofed so that no noise from for example steps or music leaves the room it is made in or intrudes where it isn't necessary, unless the portholes are opened.
The highest deck is the Sun Deck, the highest deck atop the superstructure, open topped, but with the ability to be covered from sun or rain by oilskin cloth. The large deck is only broken by the main mast and its maintenance hatch, but other then that, it can act as an outdoor gathering area or lounging area in any other capacity the owner sees fit. Provisions for covering the Sun Deck either partially or completely against sun or rain are installed on the mast and the railings. The last five metres of the Sun Deck are slightly elevated to provide either a stage or a lookout over the aft. Besides the main mast elevator, the Sun Deck can be entered and left by using one of the two flights of stairs going down to the Bridge Deck. The Sun Deck is floored with laminated Great Woods Oak, but that can be changed depending on the customer's wishes.
Below the Sun Deck is the Bridge Deck, with the namesake bridge, a room used for controlling the movements and directions of the vessel, as well as its communications. The rest of the deck is taken up by a small dining room, a small salon including a small library, and the Owner's Suites A and B. Prince Damir has requested that two suites are designated and established as owner's suites, simply for him and his daughter to have their own rooms on the vessel. The rooms, opposite to each other, have each a small bathroom with a bathtub, showed, basin, toilet and cupboard, a wardrobe, a living room, a bedroom and a small office room with a desk.
Below the Bridge Deck, the Promenade Deck offers the most splendid promenade and as the main deck of the vessel is the heart of the recreational purposes of the Aurelia-class Sailing Yacht. The large dining room, which can be transformed into a ball room, cinema, communal sleeping room or for many other purposes as the situation demands it, is the centre of the deck. Behind it, the internal room of the superstructure is taken up by a Hammam, a special type of Kyreanain Hot Bath and a tea room, as well as a toilet. The outside of the superstructure is taken up by the promenade, running along either side of the large dining room. On the foredeck, below the foremast, is open space to be used as the day demands it, including as a sporting area or for welcoming guests aboard as the gangplank leads here. There is also the possibility to use the area as a 'flight deck' for small helicopter drones and remote controlled aircraft, including fixed wing aircraft up to a certain size (however, this is not a helipad for a full sized helicopter). The aft, below the mizzenmast, is similarly free, but provisions to hold deckchairs in position are provided, including basic deckchairs. At the aft, a ladder leads down to the water, providing access to the sea for going for a swim, while a small board can be used for a more immediate access. Also sitting at the aft is the vessel's dinghy, a Majestic-class Boat (without pushboat, price already included), hanging from davits over the aft, ready to be lowered in case of need.
Below the Promenade Deck, the Passenger Deck houses the other eight-teen passengers in six double-staterooms and six single-staterooms. Each staterooms has a small bath, with a shower stall, a cupboard, sink and toilet, one or two closets, a desk and a dresser Portholes allow for looking at the sea. Also positioned on the Passenger Deck is a small sickbay and a storage room for a small amount of freight.
Then comes the waterline.
The crew consists of a Captain, ten men deck crew, a doctor, two chefs and eight stewards or stewardesses, depending on personal taste, berthed on the Technical Deck in six quarters: Four four-men bedrooms for the deck crew, the cooks and the stewardesses, own quarters for the Captain and the Doctor. The galley, storage rooms for the food to be consumed and other consumeables, including a freezer and a deep freezer, a washing salon, a workshop for the ropemaker, electrician and the sailmaker, as well as storage rooms for their working materials, and the pump room with the bilge pump are on that deck as well.

Propulsion - Capall na dTonn
The vessel has three masts, the highest of which is 42.1 metres, rigged in the distinctive Capall na dTonn Type, which was developed by Selkie Shipbuilders in the 16th century and perfected in the following centuries, making it worthy of the name: Horse of the Waves.
Although rarely three-masted (usually being two-masted), these ships were fast, agile and could load quite a bit of freight with a small crew, in other words, ideal private vessels for trade and nowadays recreation.
The three masts, foremast, mainmast and mizzen mast, all carry trapezoid sails, controlled by a pole along their heads at the peaks, usually with a running backstay. These sails are relatively easy to control with a small crew and catch a maximum amount of wind, thus providing a maximum amount of propulsion. In addition to that, the foremast also has two triangular sails, the jib and the fore staysail.
While technically all types of cloth can be used as sails, we recommend canvas.

As it was made clear several times now, the Aurelia-class Sailing Yacht is completely driven by the wind and neither has auxiliary engines nor a power generator onboard, but it has ways of producing own power, similar to the ones used aboard the Majestic-class Boat, namely a series of wind generators on the top of the masts with two metres of diameter, as well as three hydrogenerators each to port and starboard, fitted into the bilge keels. With these power generators, enough power for all of the vessel's systems is provided, with excess power being stored in battery pack underneath the masts and on the Technical Deck.

Interior Design
Besides evergreens like Art Deco, different Expressionisms and other art styles, we offer the Aurelia-class Sailing Yacht in the following interior design styles:

'Children of the Great Woods' are the Bláth Fiáin, wild flowers, of the Free Lands. Hermits and recluses, living alone or in smaller groups, seldom leaving the Great Woods - some might call them escapists, but some of them lived this way since their very birth. These low-tech people, being a Selkie-synonym for absolute freedom, developed their own artistic style of interior design, one this choice tries to emulate - but not absolutely, of course, you are still on a Yacht, after all.
All fur in this design is artificial fur for reasons of preservation of wildlife, lowering of costs and ease of cleaning.

The rooms are floored and panelled with wood, looking rugged, their patterns and their art being their veins. Furniture, massive, yet light, of good and solid wood dominates. The beds are low, covered in fur blankets, warm and homely, allowing to sink into the soft hairs.
Where there is no wood, it is covered by simple, yet intricately knotted carpets, underlining the simpleness of the design. Different kinds and strands of wood are used to create artwork out of the floors and walls, only visible to those with keen eyes and keener minds.


The Kyrenaian Interior Design is a reminder of the Sultana's Palace in Utica, Kyrenaia, taking elements of it and incorporating it into this mobile sailing home: Hand-woven carpets, silken curtains, cushions and mosaics in the Hajar Saghir Style.

The mosaics, laid in the Hajar Saghir Style, or Little Stone Style, are mosaics made of little coloured stones or sometimes even naturally coloured stones, depicting appropriate scenes and patterns, for example, the floor of the Hammam could be decorated with different hues of blue, especially the baths themselves, to depict the blue of the sea. Besides the Hammam's floor, the floors of the dining rooms, the salons and the living rooms of the Owner's Suites can be decorated with these mosaics.
The other rooms are equipped with hand-woven Kyrenaian carpets over wooden floors, panelled with woods as well, but partially hidden by curtains of silk and other fine cloths. The bathrooms are tiled with ceramic tiles, colours and patterns being up to the customer.
This decoration style usually uses cushions on the floor and sofas as seating inside, but there are several divans provided.


Own Design
If you have your own idea about how to design the interior of your new yacht, please notify us. We can make it according to your ideas, designs and setups. Or you purchase the raw design and let artists of your choice design the interior.

More Interior Designs will be made available in the future.
You are an artist or interior designer, wishing to submit a design? Please get in touch with us via private message.

History
Sailing has been the major way of getting from A to B over seas for thousands of years before engines of steam and fuel made this way of travelling and working to an occupation for the niche - in some parts of the world, this knowledge has been retained by those keen enough to listen to their forefathers.
The main purpose of sailing vessels these days are, however, either for sports or for recreation, sometimes both.
In 2014, Prince Damir ibn-Razia approached Silverport Dockyards Limited with a request for a purely sail-driven yacht vessel for twenty passengers and a few other specifications. SDY handed this request to one of our subsidiaries, who have more experience with this kind of vessel, Bád Industries, which went to work a short time later.
A year later, the plans were ready for review, presented to Prince Damir, who ordered one of these vessels in Kyrenaian Interior Design, giving the task of developing that to an interior designer working closely with the work crews of Bád Industries in Cuan and in early 2017, the hull was launched, tugged downriver to Tipa and equipped with all of the necessary components and went for a test spin in May.
On the 1st of July, 2017, Prince Damir was officially handed the ownership of the Aurelia, undergoing a first cruise to bring her back home.

The Imperial-II-class Aircraft Carrier is the result of a request for proposal by the Willemina Imperium – requesting an aircraft carrier larger then what SDY could provide, the Imperial-I-class Aircraft Carrier. As that became apparent to Yard 15, the Office for Prototype Development, they began to plan the Imperial-II-class Aircraft Carrier as a counter-proposal, which was ultimately accepted.
Despite its relatively small size, the Imperial-II-class Aircraft Carrier is a fully capable aircraft carrier, command vessel, flagship and gunboat of the 21st century.

The Imperial-II-class Aircraft Carrier is an aircraft-carrying catamaran, with one large main hull and a secondary, smaller hull, connected to each other by a platform or an Aka, basically making this secondary hull into an outrigger, or Ama, while the main hull is a Vaka. The Imperial-II-class Aircraft Carrier is 263.8 metres long, overall, has a beam of 79.2 metres maximum and a draught of 7.8 metres, when fully loaded and when measuring the Vaka.
The hull form of a catamaran, or multi-hulls in general, has a number of advantages over monohulls, mainly concerning the stability. Roll and yaw, especially in heavier seas, is reduced when compared to monohulls, thus reducing motion, thus both preventing sea sickness and providing a stable platform to work on, as well as making radar operations more efficient. It also allows for lighter vessels, which in turn means faster vessels.
However, there are some disadvantages to this hull form as well, as a multi-hulled vessel must pass over a wave instead of slicing through it. Also, multi-hulled vessels require a wider berthing space due to wider a beam.
When fully loaded, the Imperial-II-class Aircraft Carrier displaces 65,000 tons.

The Imperial-II-class Aircraft Carrier is powered by four Ga-17 Mark II Nuclear Reactors, the same as used onboard of the Beag-class Aircraft Carrier. The Ga-17 Mark II is reliable and proven, producing 75 megawatts of energy per reactor, which are used to power everything aboard the vessel. Basically, these reactors work just like those on dry shore do, needing 90 percent enriched Uranium Fuel Cells.
The power generated by them powers, amongst other things, four electrical motors in two azimuth thrusters, each with one controllable pitch propeller for better power efficiency and easier manoeuvring. Maintenance on these azimuth thrusters is easy and cheap as well.
These engines drive the Imperial-II-class Aircraft Carrier to a maximum speed of 32 knots or 59.25 kilometres per hour over a, theoretically, unlimited range. The vessel has an endurance of roundabout forty days on own stores.

Electronic Warfare and decoys
The Imperial-II-class Aircraft Carrier is equipped with Electronic Countermeasures, Electronic Support Measures and Electronic Protection, thus enabling the Imperial-II-class Aircraft Carrier to attack with electronic measures, defeat enemy electronic countermeasures and protect oneself against enemy countermeasures.
Furthermore, the Imperial-II-class Aircraft Carrier is equipped with a Multi-Ammunition Softkill System, a launcher for decoys, which operate in conjunction with the sensors to calibrate the own decoys to operate on the relevant wavelengths to confuse enemy missiles and send them striking the decoy and not the ship, and a torpedo decoy launcher.

Sensors and Processing Systems
The Imperial-II-class Aircraft Carrier is equipped with an extensive radar suite for the detection of enemy aircraft, and sending them to their demise, and the control of own aircraft and air assets. Most of the radars can also pick up missiles - in combination with the Type 900 Datalink, a Duplex Communication System for sending and processing data in real time, the information gathered by the radars is sent to the weapons, which then can began with fighting.
Core of the radar suite are two Nuacht N-13 Mark III Multifunction Radars, operating on the A-Band and being able to detect targets up to 500 kilometres away from the vessel (the particularities of that depend on the aircraft type, weather and a few other factors). These Multifunction Radars can also act as surface search radars, for navigation and a variety of other things - as proven and capable radars, in use on many of SDY's military vessels, they are sure to fulfil any mission given to them.
The other core of the radar suite is a massive Nuacht N-22 Mark III Air Surveillance and Control Radar Array, a 3D Air Search Radar Array with four panels, operating on the S-Band.
For the aid of the anti-aircraft weapons in need of such an assistance, for example guided missiles of the non-self-seeking variety, the Imperial-II-class Aircraft Carrier carries two Nuacht N-38 Fire Control Radars.
As the Imperial-II-class Aircraft Carrier is a vessel primarily designed for aircraft handling and aircraft operations, the vessel is equipped with two Digital Carrier Surveillance Radars, Nuacht N-101, with triple redundant systems and the capability to act as weather surveillance radars. It is a similar system to the one used on land-based airports and air bases, only mounted on a warship and optimized for acting as a carrier air traffic surveillance radar together with the other radars.

Crew Facilities
Most of the crew is housed on the outrigger-hull, which leaves the main hull for integral parts like the nuclear reactors, facilities for aircraft maintenance and storage, while also giving the crew much room to live. Six decks are part of the outrigger-hull, plus the superstructure mounted on it, with bridge, tower, radars and so on.
The crew and the air crew are housed in 800 bunks in 500 cabins, with an additional 100 bunks in 40 cabins for housing reserves, for admiral staffs or larger air crews. Two large galleys, capable of serving 550 meals per hour, with three dining areas, fill the crew's stomachs, while two small cinemas, six sports rooms and an onboard library (being stocked with books of the customer's choice) serve the entertainment and winding down of the crew.
Medical attention is provided by a 15 bed hospital with dental surgery and an intensive care unit. In case of need, the freight rooms can be easily transformed into sickbays, for example in case of evacuations.

The Imperial-II-class Aircraft Carrier is equipped with an extensive weapons suite, which is mostly geared towards self defence, organized in layers. The outermost layer is always the own air group, radar, systems for Electronic Warfare and the carrier's escorts and their weapons.
The next layer are the three Feadán Fe-12 Mark I VLS-modules, providing 24 cells for missiles – from long-range anti-air missiles to ASROC to cruise missiles, everything capable of hot-launch and compatible with the cells' systems can be fitted inside, including multi-packed.
The last line of defense are six Ceantar C-84 Mark II 30mm CIWS, a semi-autonomous missile defence system, which is bolted to the deck, supplied with power and radar data and can, from there, act on its lonesome or be controlled remotely. The C-84 Mark II even features its own little fire control radar for target-acquisition and for engaging said targets.
Last, but not least, the Imperial-II-class Aircraft Carrier has four balconies, structures on the vessel, where the customer can decide what to place there, as those can serve as mounting stations for additional CIWS, RAMs, heavy weapons teams or even as recreational balconies.

Air Group and installations
The Imperial-II-class Aircraft Carrier can carry an extensive air group, of up to 85 aircraft, the exact number depending on types and arrangement of the aircraft in question. We recommend an air group of 45 to 55 aircraft, depending on types and mission of the carrier, both for easier handling of aircraft and of crews. This does include remotely operated aircraft.
The maximum capacity, depending on types of aircraft, is around 85 aircraft, including remotely operated aircraft.
From the hangar, spanning the entirety of the Vaka and being six metres in height, two lifts for aircraft lead upwards to the flight deck, while two ammunition lifts lead from the ammunition storages up into the hangar and even up to the flight deck.
Aircraft are launched via an Electro-Magnetic Aircraft Launch Systems, EMALS for short, being far more efficient, both in terms of energy conversion and in terms of take-off frequency, at launching aircraft while being easier to maintain due to less moving parts then for example steam catapults. For recovery, the Imperial-II-class Aircraft Carrier is equipped with standard arresting gear and a net-landing backup.
In the outrigger's superstructure, a drone control room allows for the remote-operation of drones and similar aircraft.

History
The Imperial-II-class Aircraft Carrier began its life like so man designs of SDY begin their life: As an idea, had in boredom by an engineer of SDY, who scribbled down a rough idea for a catamaran-hulled yacht. From this idea, the Dhá, a yacht of SDY-production and a unique design, was developed for a rich foreign customer.
This was also the first venture of SDY into multi-hulled vessels, basing them off of old pictures and diagrams of catamaran-like boats observed and photographed on the Archipelago at the end of the 19th and at the beginning of the 20th. The art to build these vessels, capable of astonishing feats, was mostly lost by that time and until today, the art is on the verge of extinction.
Still, SDY began to use the experience gained with the Dhá and built on it, developing SWATH-Hulled vessels like the Aiteal-class Oceanographic Research Vessel or, as a first venture into multi-hulled military shipbuilding, the trimaran Glorium-class Command Ship. All of which were successful designs in their own right and did what they were constructed well.

And in 2017, the Imperial Navy of the Willemina Imperium requested a vessel larger then SDY could produce - and our engineers already had the perfect solution: A Catamaran-hulled vessel, reviving the old art in steel and with nuclear reactors instead of wind or paddles. As the original specifications called for the possibility of newer, and currently experimental, weapons “like Lasers and stuff” (to quote the Forelady of Yard 15) to be deployed in the nearer future on board of these vessels, SDY added the provisions to re-equip and adapt the Imperial-II-class Aircraft Carriers relatively easily.

The Maighdean-class Missile Cruiser, known as the Pompey-class in the Imperial Navy of Vionna-Frankenlisch, is a class of Guided Missile Cruisers developed for the SDF-Navy and soon also adopted by the Imperial Navy, as a request for proposal resulted in a vessel rather similar to the required specifications. Being the first in a long line of cooperations between SDY and the Imperial Navy, the Maighdean-class Missile Cruiser is built for operating alone and with other ships, either as a flagship for a task force or as an escort for other vessels, equipped for combating targets above, on and below the seas.

The term maighdean means maiden. The name Pompey comes from Emperor Pompey, an ancient Roman Emperor.

Design
The Maighdean-class Missile Cruiser is a monohull-design, classical, but easily cutting the waves with a bulbous bow, sitting stable in the water. Displacing thirteen thousand tons of water, the vessel of 205.3 metres length and with a beam of 19 metres have a maximum draft of 10.6 metres. The vessel is built with a reduced radar-signature in mind, but is not a fully-dedicated stealth vessel.
Powered by two capable and proven Ga-17 Nuclear Reactors, each producing 75 Megawatts of energy, the maximum speed of the Maighdean-class Missile Cruiser is set to 36.2 knots or 67 kilometres per hour. The vessel is only limited by its endurance, which lasts for thirty days before resupplies are needed, with its full crew complement of 610 people (40 officers, 306 sailors, an optional admiral's staff of 64 people and two companies of naval infantry with up to 200 troops) onboard.
Said naval infantry can be deployed either by helicopter, see below for details, or by three collapseable dinghies or six rigid-hulled inflatable boats (RHIBs for short), for which provisions to carry and deploy are provided. As these are located behind a hull plate, which can be opened, these installations do not compromise the stealth features of the Maighdean-class Missile Cruiser.
The Maighdean-class Missile Cruiser's propulsion is powered by the electricity of the nuclear reactors, driving two electrical engines on one shaft each, which allows for ease of maintenance, reduction of costs and space savings. This allows for a maximum speed of 36.2 knots, or 67 kilometres per hour. Due to the nuclear reactors, this speed can be employed continuously, sea state permitting. At the end of both shafts, propellers with controllable pitch allow for maximum energy efficiency. For navigating in small spaces, the Maighdean-class Missile Cruiser is equipped with a set of electrically driven bow-thrusters.
The Maighdean-class Missile Cruiser is armoured with Kevlar Splinter Plating over critical areas, for example the nuclear reactors.

Electronic Warfare and decoys
The Maighdean-class Missile Cruiser is equipped with an extensive suite for Electronic Warfare, enabling the vessel to conduct operations in employing Electronic Countermeasures itself to confuse enemy sensors, to protect itself and the task force from such measures with Electronic Protection, or Electronic Counter-Countermeasures, and support own forces with equipment to detect, intercept and analyse radiated electromagnetic energy for the purpose of threat recognition or planning.
Data gathered by these latter measures, as well as all other data gathered by the extensive sensor suite described below, is both used onboard, distributed by a Type 900 Datalink described below as well, and amongst the other vessels of the fleet by an Artio Battlescape Network Mark V, one of the most modern battlescape network systems in the world, capable of duplex communication via direct line of sight or by satellite or by radio transmission, each with a set of advantages and disadvantages one has to consider: For example, the direct line of sight communication requires the vessels to be relatively close to each other, around forty kilometres is the tested maximum, transceivers being perfectly aligned to each other, with the distinctive advantage, that the sharing of data can only be disrupted by putting things between the two vessels and said communication being nearly impossible to listen in to. The Mark V is capable of switching all three modes by basically switching a button, with the direct line of sight communication system always being ready to send and receive.

In case the Electronic Countermeasures fail, it never hurts to have not one, but two backups, one of which is the extensive weapon's suite described below, the other being decoy launchers.
For the defence against torpedoes, the Maighdean-class Missile Cruiser is equipped with two kinds of countermeasures, one belonging to the Variable Depth Sonar described below, the other being a separate system. This system launches sonar decoys much akin to the ones used by submarines to confuse enemy torpedoes to thinking, that the decoy is the better target and instead attack that.
For the defence against missiles, the Maighdean-class Missile Cruiser carries a Multi-Ammunition Softkill System with decoys operating on all relevant wavelengths to confuse modern, sensor-guided missiles, while two launchers for chaff and flares are supposed to confuse less advanced and heat-seeking ammunition.

Sensors and Processing Systems
To perform its many missions, the Maighdean-class Missile Cruiser has a wide variety of sensors at its disposal, chiefly amongst them being radar and sonar systems, which are connected with each other via a Type 900 Datalink, a ship-wide system for duplex communication to share target information and data collected by the sensors, as well as the data transmitted by a Battlescape Network like the Artio. Said data then can be used to effectively and easily fight an enemy, on the water, above the water and under the water.
The core of the radar suite are two 3D Air Search Radars, one being a Nuacht N-22 Mark III Air Surveillance and Control Radar Array, four arrays with a detection range of 463 nautical miles and the capability to track up to 900 targets, including targets in low Earth orbits, namely satellites and ballistic missiles. The other is a new Nuacht N-111 Mark VI, the result of a long and drawn out development process to produce a 3D Air Search Radar with a range of 450 kilometres tracking up to 1,000 targets and use a database to match the returning radar-signature to an aircraft, be it a drone or not, or another flying object all while collecting data about heading, speed, altitude and transponder codes. On that note, the N-111 gives the code UFO to any unidentified flying object, which makes updating the database at any opportunity a must.
The Maighdean-class Missile Cruiser also carries two Nuacht N-13 Mark III Multi-Function Radars, which are capable of acting as both air search, surface search, navigation and fire control radars, depending on what the situation demands.
Completing the radar suite are two dedicated fire control radars, Nuacht N-38 Mark IIs, which are used to track the fire of the own guns and missiles and leading the latter to their targets and adjusting the former.
For detecting and eventually combating enemy submarines, the Maighdean-class Missile Cruiser is equipped with a bow-mounted sonar and a Variable Depth Sonar, a Nuacht N-81 Mark II. The latter is capable of detecting targets at a distance of up to 150 kilometres with an accuracy of less then 100 metres at this range, all while operating in very rough seas. It can be used for both active and passive surveillance at the same time, and analyses received signals, keeping apart, if it is a torpedo, a submarine or a whale. The N-81 also features a torpedo alert system. Towed on a single line, the N-81 provides surveillance 360 degrees around the vessel.
Important to note as well are the Radar Warning Receivers scattered around the vessel, providing early warning in case of a radar, for example of an anti-ship missile, locking onto the Maighdean-class Missile Cruiser.

Aviation Facilities
The Maighdean-class Missile Cruiser is equipped with a medium drone catapult, which can be extended from its storage space to launch a medium-sized drone, as well as the appropriate recovery system. For command and control of these drones, the Maighdean-class Missile Cruiser is equipped with a drone control room, which is capable of taken over control of drones from other vessels and surface installations as well.
At the same time, the Maighdean-class Missile Cruiser is capable of carrying two medium-sized helicopters, but the flight deck not is not rated for the operation of vectored thrust VTOLs. These helicopters are maintained in the same hangar as the drones.

    4x balconies
The Maighdean-class Missile Cruiser is equipped with a large weapons suite to perform a variety of combat missions as outlined above.
Core of its abilities and firepower are the twenty-eight Feadán Fe-12 Mark II VLS-modules, each having eight shafts for missiles of every kind and size, some of which can be double-packed, triple-packed or even quad-packed, depending on type and size of the missile in question. The shafts can be loaded with all manner of hot-launching missiles, from short-range point defence missiles to long-range cruiser missiles, anti-ship missiles and anti-submarine missiles. With a total of 224 shafts, there is more then enough room for missiles for any kind of mission.
As an additional offensive capability, the Maighdean-class Missile Cruiser is equipped with a bow-mounted Gabha G-91 Mark IV gun, the largest gun currently on any vessel in SDY's catalogue. While firing rocket-assisted ammunition, the G-91 has a range of up to 150 kilometres. The Pompey-Subclass replaces this gun with a 203mm gun.
The rest of the cruiser's armament is mostly defensive in nature, with four Ceantar C-44 Mark II 40mm AA-guns, although that is a bit of a misnomer. The C-44 Mark II, designed to be controlled by an external fire-control system, either automatically or by a human operator, is more of a multi-purpose weapon, capable of successfully engaging all manner of air and surface-targets, including small ones like Anti-Ship Missiles.
Dedicated to defence are the six Ceantar C-84 Mark II 30mm CIWS and Ceantar C-78 Mark II 23-cell RAMs, one being an automatic CIWS with its own little targeting radar, which basically needs to be bolted to the ship and supplied with power and ammunition to function, the other being a rolling-airframe missile system, dedicated to air-defence against aircraft and ammunition, loaded with small missiles designed to shower the enemy missile or aircraft with shrapnel.
For submarine hunting, the Maighdean-class Missile Cruiser carries two Gráinneog G-321 Mark II Hedgehogs, which use the Tormán Mark I Shell: Rocket-launched into the air at a range of up to seven to ten kilometres, into the general direction of the enemy submarine. The Tormán Mark I carries a small torpedo, which is a small, passive acoustic homing weapon optimized for attacking submarines. Each delivers a 20 kg warhead onto the target, one surely causing problems, but several causing the submarine to sink.
Additionally, the Maighdean-class Missile Cruiser carries four balconies, positions on the superstructure, which can be used as positions for heavy-weapons teams or for additional CIWS, sensors, launchers for chaff and flares or simply left free for recreation of the crew, depending on the preferences of the user.

History
The SDF-Navy is classically a cruiser-navy - from the venerable light cruiser SDFS Rhiannon and her five sisters, who have namesakes to this day, to other vessels, the SDF-Navy always had cruisers by one name or the other. But as time and technology progressed, so did the cruisers, so that by 2000 the SDF-Navy was looking for vessels, that could fill the roles projected for cruisers: Leading of other vessels, protection of own vessels, combat against targets above and below the sea, far away from the own shores.
This concept was, in part, a result of the SDF-Navy's plans from a long time ago, then further developed into more general war plans by the 2000s - and became, nowadays, a classification the SDF-Navy uses consistently. With the relations to Lutetii normalizing, there would be little need to ships specifically designed to counter Lutetiian vessels. Regardless, the Navy approached the shipyards and construction bureaus of the Free Lands, which were experienced in building and developing watships, with a request for proposal, which turned to be the Maighdean-class Missile Cruiser in time and after several adjustments.
The final design, although finished by SDY, is a combination of several designs, especially concerning the arrangement of the superstructure. The hull, though, is SDY.
In 2017, as the Imperial Navy of Vionna-Frankenlisch sought for a new cruiser design, SDY offered them a peak at the Maighdean-class Missile Cruiser, which was surprisingly close to the design the Imperial Navy had in mind. From there, it didn't take long for them to join the development.
The only major difference between the Maighdean-class Missile Cruiser as the SDF-Navy has them and the vessels of the Imperial Navy is the refitting of the latter with 203 millimetre guns instead of the 135 millimetre gun of the Maighdean-class Missile Cruiser.

The SDF-Navy ordered three vessels, SDFS Maighdean, SDFS Bruinneall and SDFS Cailín, the Maiden, the Fair Maiden and the Girl, respectively.

The Ceasia-class Escort Carrier is the result of a request for proposal of the Imperial Navy of Vionna-Frankenlisch towards Silverport Dockyards Limited. The Ceasia-class Escort Carrier is intended to support smaller task forces with air support and to act as a flagship of said task forces, as well as to be capable in anti-submarine warfare, to transport small amounts of troops to their destination and to provide medical aid in case of need.
This also makes the Ceasia-class Escort Carrier capable of conducting relief operations in disaster areas.

Design
The Ceasia-class Escort Carrier is a classical monohull-design, 250.4 metres in length, 38.2 metres wide at the flight deck, and with a draft of 7.9 metres. Fully loaded with everything needed, the vessels has a displacement of 28,000 tons.
600 sailors, already including the air crew, man her, plus additional space for 300 troops and their equipment. That includes a vehicle deck for up to fifty light trucks like Gabha Blacksmith's TLM 2010 (not included in delivery) or equivalents, which can be used as an auxiliary storage room for aircraft, either in an assembled state or in an disassembled state. Said vehicle deck is 3.5 metres tall.
The sailors are, in the standard version of the Ceasia-class Escort Carrier, housed in berthing rooms akin to the ones used on the Hjemland-class Sailing Vessel: The arrangement sees the inspiration of the capsule hotels used for a maximum amount of comfortable accommodations for the crew with minimal weight and costs. The capsules, modular and relocatable fibreglass blocks, are 2.5 metres long, 1.25 metres wide and 1.5 metres high, a mattress of 2.25 metres in length and 1 metre in width being provided. A closable cupboard runs along the side of the capsule, a storage for the inhabitant's belongings, with a locker for clothing and larger objects. A foldout panel by the entrance of the capsule is usable as a desk or working surface, the privacy is assured by a curtain, light provided by an internal lamp. The cleaning facilities are communal. If wished by the customer, other arrangements can be made.
The Ceasia-class Escort Carrier is lightly armoured, with plating providing protection over sensible areas, like ammunition holds, fuel tanks and generators. While the hull and superstructure is constructed with the thoughts of a reduced radar-signature, the Ceasia-class Escort Carrier is not a dedicated stealth-vessel.
The Ceasia-class Escort Carrier can, besides its vehicle deck's load, carry up to 300 soldiers of landing troops to be delivered by helicopter. Support facilities for these include a small onboard hospital with fifty beds, an Intensive Care Unit and a dentist, as well as own berthing. For short-range trips, the number of landing troops can be raised to up to 900 soldiers, but it will be uncomfortable.

Propulsion
The Ceasia-class Escort Carrier is powered by three diesel generators, which produce 90,000 kilowatts of power together. This power is needed to operate every system on the vessel, from the coffee maker to the radars and, of course, the engines. Such a system is known as an IEP-System, Independent Electronic Propulsion, main advantages being the ease of maintenance and operating costs due to the absence of gearboxes, but mostly the saving of space onboard, as well as the possibility to spread the generators out.
Two of the generators are located near the stern, while the third is close to the bow. With each of them capable of providing enough power for basic functions of the vessel, the vessel can return home to port in case of major damages under the own power.
Two azimuth thrusters with electrical engines in them provide propulsion, steering and a speed of close to 30 knots or 56 kilometres per hour with a range of 10,000 nautical miles, or 18,520 kilometres, at a speed of 20 knots, or 37 kilometres per hour. Due to these azimuth thrusters, as well as a bow thruster, the Ceasia-class Escort Carrier is highly manoeuvrable and relatively agile, as well as capable of docking easily without help.

Sensors and Processing Systems
Technical Data - Radar Suite
2x Nuacht N-12 Mark II Air/Surface Search Radars (Multi-Function)
    Band: X
    Range: 400 km
    Height of Target: 9.5 km
    Power: 100 kW
1x Nuacht N-101 Digital Carrier Surveillance Radar
Core of the sensor suite found on the Ceasia-class Escort Carrier are two Nuacht N-12 Mark II Air/Surface Search Radars, multi-function radars, which not only can act as air search and surface search radars, and quite effectively ones at both tasks, but which can also be employed as weather radars, navigation radars and in a few other functions. This keeps the costs of the Ceasia-class Escort Carrier relatively low while not giving up any important capability.
The only other radar on the Ceasia-class Escort Vessel is a Nuacht N-101 Digital Carrier Surveillance Radar, an invaluable system for carrier operations. This radar allows for the surveillance and control of air traffic, basically the same as used on civilian airports ashore, only used on an aircraft carrier. In a secondary function, it can also act as a weather surveillance radar.
In addition to the radar, the Ceasia-class Escort Carrier carries a system known as an Infrared Search and Track, or IRST, which search and track infrared emission, for example of aircraft and missiles, up to a range of 100 kilometres, depending on the weather. These passive sensors are especially useful in situations, where the radar is jammed or inoperable or when fighting stealth craft, because they might hide from radar, but there will still be heat emissions.
For detecting, and ultimately combating, submarines, the Ceasia-class Escort Carrier is equipped with a Bow Mounted Sonar and a Variable Depth Sonar, a Nuacht N-81 Mark II VDS. With a maximum range of up to 150 kilometres, the N-81 can pinpoint an enemy submarine with an accuracy of less then 100 metres at this range. It is capable of operating in very rough seas, providing detection and surveillance, passive as much as active at the same time, in 360 degrees around the vessel, as well as the analysis of any received signal – which includes a torpedo alert.

All of these sensors and the weapon systems are linked to each other and connected to the output stations by a Type 900 Datalink. This duplex communication system links sensors, processing systems and output stations, which includes weapons systems, together in real time to share data and commands amongst each other. In several tests conducted by SDY, as well as by active service in several navies around the world, the Type 900 Datalink proved to be a capable system and up for its intended tasks.
It is also connected to the Artio Battlescape Network System onboard, enabling it to share its data with other vessels and stations in the network.

Electronic Warfare and Decoys
The Ceasia-class Escort Carrier is equipped with a multitude of systems for electronic warfare and for avoiding enemy missiles without firing a shot, as well as harming the enemy without firing a shot. Core of these abilities are the suites for Electronic Countermeasures, Electronic Support and Electronic Protection, ECM, ESM and EP for short.
Electronic Countermeasures confuse enemy sensors, for example those of guided missiles, while Electronic Protection, or Electronic Counter-Countermeasures, try to avoid exactly that, differing between the real and false signals. Meanwhile, Electronic Support Measures record and analyse radiated electromagnetic energy for the purpose of threat recognition and planning – while this does include radio transmissions, the suite is not capable to decipher radio messages, this being the core-capability of an ELINT-Suite.
Additionally, the Ceasia-class Escort Carrier is equipped with suite of decoys, namely a Multi-Ammunition Softkill System. This system, connected to radar and ESM-Systems, launches decoys, which operate on all relevant wavelengths of the electromagnetic spectrum, confusing modern, sensor-guided missiles to attack the decoy, not the ship.
Another important decoy launcher are the Torpedo Decoy Launchers. While the VDS can act as a torpedo decoy, the actual Torpedo Decoy Launchers, two Baoite Mark IIIs, are placed on both sides of the vessel, one on port and one on starboard. These launch a series of expendable decoys, which emit a more tempting acoustic signature for the torpedo to lock onto.

Armament
The Ceasia-class Escort Carrier is armed for self-defence only, namely with four Ceantar C-84 Mark II 30mm CIWS, a six-barrelled CIWS firing 30mm projectiles onto the enemy. The C-84, with a maximum firing range of seven kilometres and a rate of fire of 4,500 rounds per minute (which is actually throttled a bit), only needs to be bolted to the vessel, supplied with ammunition and power to function as the C-84 has its own little fire-control radar unit.

Air Group
The Ceasai-class Escort Carrier's main-capability is the ability to carry, launch and recover aircraft, be they fixed-wing or rotary wing craft alike. Depending on the configuration and layout, the vessel can carry up to thirty aircraft and is modelled appropriately. Core of any operations is the hangar deck and the flight deck.
The tall hangar deck, which is lightly armoured due to the volatile nature of its occupants, is capable of storing and the place for aircraft maintenance onboard, as well as arming and refuelling. Two lifts connect the hangar deck to the flight deck, one of which leads down to the vehicle deck as well, while two smaller ammunition lifts lead to the ammunition storage. The hangar deck offers comfortable parking for 18 aircraft, with the remaining twelve of the onboard complement to be stored on the flight deck. If need should arise, the vehicle deck can be used as an aircraft storage as well, but lacks most maintenance functions.
The flight deck is rated to support the operations of vectored-thrust VTOLs, offers storage room for twelve aircraft to the sides of the superstructure, namely the island, and three dedicated landing spots for medium-sized helicopters behind the flight deck installations – three more optional landing spots are marked on the 'runway'.
Said runway is for the operations of fixed-wing STOVL-aircraft, planned with 175 metres in length including the ski-jump at the end of it. Of course, for launching aircraft over the runway, the marked optional helicopter landing spots are not to be in use. When an aircraft is launched, it makes a conventional rolling take-off, towards the ski-jump, which it uses to launch itself into the air at an angle, thus ensuring a positive rate of climb upon take-off with momentum ensuring enough time for the aircraft to achieve enough speed and thrust to fly. Due to the aircraft's nature as Short-Take-Off/Vertical-Landing Aircraft, there is no need for arrestor gear.

History
The Ceasia-class Escort Carrier is the result of a long development process, which actually started long before the foundation of Silverport Dockyards Limited: In the 40s, the University of Silverport and it's Engineering Department experimented together with the Cé Aeronautics Company (which developed and built the Monarcha M-16 Giodróg Torpedo Bomber) with shore-based ski-jumps to make the runways for both military and civilian aircraft alike shorter. Although these experiments, using piston-engine aircraft, were partially successful, they were put on hold and later abandoned due to the bankruptcy of Cé Aeronautics in 1946.
For a while, no projects of this kind were launched, until Gabha Blacksmiths Limited began similar experiments with jet-aircraft in the 60s and approached the SDF, if there was an interest for the results – there was none, but Gabha developed a family of jumpjets in the 60s and 70s for export, which were a bit of a bad seller, soon to be forgotten. One of the prototypes was placed in a museum in Traverse.
During the Second Vellenge-War, there were plans to repurpose freighters as jumpjet-carriers, but that was soon abandoned. In the 90s, the SDF-Navy thought about acquiring a carrier capable of handling STVOL-aircraft and helicopters to provide aerial support to a fleet, plans were drawn up, including at SDY, but archived when the SDF-Navy abandoned the project.
After the Battle of Marley Bay in 2012, the situation changed drastically and the need for aerial support became apparent – someone remembered the old plans from the 90s, but those were soon discarded again, due to budget constrains, the SDF-Navy much rather preferring a helicopter carrier, which later became the Sealgaire-class Helicopter Carrier.
As, following the Maighdean-class Missile Cruiser, the Imperial Navy of Vionna-Frankenlisch approached SDY with a request for proposal for an escort carrier, capable of providing air support, escorting minor task forces and maybe even leading them. The result was the Ceasia-class Escort Carrier.

Pricing
One Ceasia-class Escort Carrier without aircraft complement: 900 million NSD.

Ragnarok-class Arsenal Ship

Postby The Selkie » Mon Nov 06, 2017 2:23 pm

Technical Data
Displacement: 19,000 tons full load
Length: 255.4 m
Beam: 24.6 m
Draft: 7.2 m
Propulsion:
    1 nuclear reactor, 75 MW,
    2 azimuth thrusters
Speed: 34.5 knots (63.9 km/h)
Range:
    Theoretically unlimited,
    Endurance for 35 days.
Complement: 300 sailors
Sensors and processing systems:
    1x Air Surveillance and Control Radar,
    2x Air/Surface Search Multifunction Radars,
    Bow-mounted sonar,
    Type 900 Datalink
Electronic warfare and decoys:
    Full ECM- and EP-Suites,
    Multi-Ammunition Softkill System,
    Artio Battlescape Network
Armament:
    50x 8-cell VLS-modules,
    4x 30mm CIWS
Aircraft carried: None.
Aircraft facilities: Helicopter landing pad.
The Ragnarok-class Arsenal Ship is the result of a request for proposal by the Free Missouri Naval Development Agency for a ship mostly armed with missile shafts for varying purposes, with a small crew and a few other properties. The result is a vessel carrying a veritable arsenal of missiles with her for varying purposes.

Design
The Ragnarok-class Arsenal Ship is a classical monohull-design, armoured with splinter plating over vital areas, like the reactors or the VLS-shafts. The vessel is 255.4 metres long, 24.6 metres wide and has a draft of 7.2 metres when reaching the full load of 19,000 tons.
The superstructure was designed with a reduced radar-crosssection in mind, due to angling and as little in the ways of horizontal lines as possible, but while this reduces the radar-signature of the Ragnarok-class Arsenal Ship, it is not a dedicated stealth vessel.
Powered by a Ga-17 Mark II Nuclear Reactor, the same as used aboard the Beag-class Aircraft Carrier and other nuclear powered vessels of SDY, the vessel has 75 Megawatts of energy at its disposal to power the ship's systems, from the coffee maker to the engines. Speaking of which, propulsion is reached by two powerful electrical engines in two azimuth pod thrusters, which reduces costs for maintenance and increases manoeuvrability.
To decrease further operating costs, the systems of the vessel are automated to some extend, reducing the complement needed for effective operations to 300 sailors. Not only are those systems double-redundant, there are manual overwrites in place as well.
The Ragnarok-class Arsenal Ship has no aircraft facilities onboard except a helipad fit for a small helicopter.

Sensors and Processing Systems
Technical Data - Radar Suite
1x Nuacht N-22 Mark III Air Surveillance and Control Radar Array
    3D Air Search Radar Array
    Four Arrays.
    Band: S
    Range: 463 nm
    Targets tracked: 900 in total
2x Nuacht N-13 Mark III Air/Surface Search Multifunction Radars
    Band: A
    Range: 500 km
    Height of Target: 10 km
The radar suite is the heart-piece of the sensor suite of the Ragnarok-class Arsenal Ship, composed of three radars.
The most important one is a Nuacht N-22 Mark III Air Surveillance and Control Radar Array, a phased radar array with four arrays, operating on the S-Band with a range of 463 nautical miles or 857.5 kilometres, with the capability to track 900 targets in total, from aircraft to missiles, in their complete glory as a 3D-radar, thus also providing information about the height of the target, from all angles around and above the vessel. This also enables the Ragnarok-class Arsenal Ship to act in a role to defend against ballistic missiles.
The other two radars are two proven Nuacht N-13 Mark III Air/Surface Search Multifunction Radars, capable of acting as air search, surface search, weather and navigation radars. These proven radar systems operating on the A-band can detect targets at a range of up to 500 kilometres and up to 10 kilometres high, but can only do so in 2D. Cheap, but reliable, the N-13 is very capable at its job.
The sensor suite is completed by a bow-mounted sonar, listening to noise beneath the waves.

All data collected is shared in real-time by a digital communication system for duplex communication, the Type 900 Datalink. Developed by several universities in the Free Lands for the SDF, the Type 900 is a capable and proven Datalink System in widespread use both in the SDF-Navy and in other navies around the world.

Electronic Warfare and Decoys
The Ragnarok-class Arsenal Ship is equipped with a suites for Electronic Countermeasures and Electronic Protection, the former built to deceive and trick enemy means of detection, for example radars, so that he can not attack, while Electronic Protection or Electronic Counter-Countermeasures, harden the vessel against such means.
If a missile should come closer for comfort, the Ragnarok-class Arsenal Ships is equipped with a Multi-Ammunition Softkill System, MASS for short, which uses the data collected by the radar to program decoys to operate on the relevant wavelengths, so that advanced sensor-guided missiles are deceived.

Additionally, the Ragnarok-class Arsenal Ship is equipped with an Artio Battlescape System, a system for direct communication with either a satellite or other such equipped vessels, which can be hooked up to nearly all battlescape network systems in the world. We still recommend reading the manual, though.
This system allows for duplex communication of data, for example target information, between vessels, ground stations, aircraft and ground troops for data sharing and more effective combat operations.

Weapons and Armament
As usual with Arsenal Ships, the Ragnarok-class Arsenal Ship is equipped with fifty 8-cell VLS-modules, namely Feadán Fe-12 Mark II. Each of the 400 cells is 90 centimetres long, 93.6 centimetres wide and 7.82 metres deep, designed for the hot launch of missiles. Although we recommend reading the manual, many of the missiles designed for hot launch in circulation around the world can be fired from these shafts and used to maximum effect.
For close-in defense, the Ragnarok-class Arsenal Ship carries four Ceantar C-84 Mark II CIWS, a six-barreled 30mm weapon designed for taking out incoming missiles and aircraft with a maximum range of seven kilometres. The C-84 has its own little radar for fire control and target acquisition, the only things needed for successful operations being ammunition and power.

History
Don't you know the problem, too? Sometimes, people just run out of missiles, especially when something absolutely and positively needs to die.
That is the moment, when an arsenal ship is needed.
Provided, that all the missile shafts can be filled with missiles, in this case 400 shafts, the Ragnarok-class Arsenal Ship provides the firepower needed for a wide variety of jobs, thanks to her over-abundance of missiles carried and capable of being carried.
Usually, navies try to avoid such vessels due to their limited strategic and tactical use, mainly putting all the eggs (or missiles, as the case may be) into one rather weakly protected but very expensive basket only useful for a small variety of situations, when compared to smaller, cheaper and adaptable vessels of which more can be procured and operated at roughly the same costs – still, SDY had been tossing the idea around for quite a while and never actually got the time for such a design.
That was, before the Navy of Free Missouri, and its Naval Development Agency, issued the Request for Proposal for the Ragnarok-class Arsenal Ship, basically a giant missile barge to be integrated into a network of vessels meant as a deterrent against enemy nations, both in a defensive and offensive role, and as a measure for a counterstrike in case of an attack – SDY added the ability to defend against such a first strike as well.
Development began and ended in 2017.

Pricing
One Ragnarok-class Arsenal Ship: 2.5 billion NSD.

The Corrán-class Offshore Patrol Vessel is SDY's newest patrol vessel for long-range patrols from ports with relatively little in the ways of harbour infrastructure, although it of course profits from said infrastructure. It is a police and coast guard vessel and less a military vessel.

The term corrán means sickle or hook and is the name of a character in the TV-show Marla, a Bad Boy with a Golden Heart, who more often then not finds himself on the side of the titular heroine and is hotly tipped as her love interest.

Design
The Corrán-class Offshore Patrol Vessel is a classical monohull-design of steel.
Due to high automization of the vessel's systems, the Corrán-class Offshore Patrol Vessel can be crewed by 44 sailors, plus carry a boarding team of ten soldiers, including a dinghy. The entire crew is provided with comfortable accomodations, including a small recreation room and wider bunks. An onboard cell can house up to four prisoners, but has space for eight (it might get a bit cramped).
Due to its relatively shallow draught, the Corrán-class Offshore Patrol Vessel can also operate on larger rivers and lakes.

The Corrán-class Offshore Patrol Vessel is, like many of SDY's newer designs for military and law enforcement, designed with a reduced radar crosssection, but not a dedicated stealth-vessel. Radar-absorbing materials are used with the superstructure, many flanks being inclined, with all facilities like the anchorhouse or stairwells inside of the superstructure.
The acoustic signature is reduced as well by resting the diesel generators on shock absorbers. This also serves for the comfort of the crew, as this also reduces the noise on board.

The Corrán-class Offshore Patrol Vessel has no aviation facilities bar a landing pad for a light helicopter, but no hangar. The flight deck is rated to handle vectored-thrust VTOLs if necessary.
Besides that, the Corrán-class Offshore Patrol Vessel is equipped with a catapult for launching and a small crane for recovering medium seaplane drones, as well as with a workshop to maintain them, as well as the facilities to recharge electrically powered drones and to refuel fuel powered ones. Launched via catapult, the drones can be used for reconnaissance, research, attack and a variety of other missions. The drones are recovered via net-landing.
The Corrán-class Offshore Patrol Vessel can carry up to four medium drones. Besides fixed-wing seaplane drones, helicopter drones can be carried.

For the detection of transmissions, as well as their interception, identification and location of sources of electromagnetic energy for immediate reconnaissance and threat recognition, as well as long-term planning of operations. The system also provides the capability to provide Signals Intelligence, namely by recording and decoding radio transmissions, as well as the decoding of simpler codes.

Sensors and Processing Systems
Technical Data - Radar Suite
1x Nuacht N-12 Mark III Air/Surface Search Radar (Multi Function)
    Bands: X
    Range: 400 km
    Height of target: 9.5 km
    Power: 100 kW
The Corrán-class Offshore Patrol Vessel is equipped with one combined Air/Surface Search Radar, which doubles as a navigation and fire control radar.
Nuacht N-12 Mark III Air/Surface Search Radar (Multi-Function) is a cheap and easy to operate system, capable of tracking 350 targets at maximum in TWS-Mode, from missiles to passenger planes to small fast attack craft, and to track own fire for adjustments just as easily.
The Corrán-class Offshore Patrol Vessel is equipped with a small weather forecast suite, which can be used as a mobile weather station to make accurate forecasts. As such, the crew of the Corrán-class Offshore Patrol Vessel can plan operations with more and more accurate information.

Armament
Technical Data - Weapons Systems
    1x twin 76mm L50 gun - Túirín T-12 Mark II
      Calibre: 76mm

      Magazine: 60 rounds per barrel in turret
      Barrels: 2
      Elevation: -10°to +80°
      Traverse: ±160°
      Rate of fire: 95 rds/min
      Muzzle velocity: 950 m/s
      Maximum Firing Range: 27.5 km
    2x 40mm AA-guns - Ceantar C-44 Mark II
      Calibre: 40mm
      Barrels: 1
      Elevation: -15 to +90 degrees
      Traverse: 360 degrees
      Rate of fire: 300 rpm
      Muzzle velocity: 1,150 m/s
      Maximum Firing Range: 15,000 m
    2x water cannons,
    4x balconies
The Corrán-class Offshore Patrol Vessel is a heavily armed vessel, primarily due to its Túirín T-12 Mark II turret with two 76mm main guns. While the armament seems excessive, it is with good reason as more and more criminals and pirates make it necessary for law enforcement agencies to have heavily armed vessels at the ready.
The Túirín T-12 Mark II can be used as both an anti-surface gun, for shore bombardement, as an auxillary anti-air gun for self-defense and, of course, for intimidation. With its maximum firing range of 27.5 kilometers and due to its positioning at the bow, it can use the complete range of its traverse, 160 degrees to either side, it is a threat to any enemy in any situation.
For more dedicated air defence and multipurpose-gunnery, where a 76mm gun might be a bit too much, the Corrán-class Offshore Patrol Vessel carries two Ceantar C-44 Mark II 40mm guns, originally marketed as AA-guns, but more like multipurpose guns. With one to port and one to starboard, the C-44s carried by the Corrán-class Offshore Patrol Vessel has a wide traverse for all-round protection.
As a less lethal method to dissuade an attacker from the Corrán-class Offshore Patrol Vessel or its wards, the vessel is armed with two water cannons with a throughput of 1200 litres of water per minute (seawater pumped aboard from beneath the vessel), with ten bars of pressure and a range of 65 metres. These guns, one on port, one on starboard, can also be used as deluge guns, including a function to spray firefighting foam.
Additionally, the Corrán-class Offshore Patrol Vessel's Superstructure has four balconies, positions on which additional weapons or heavy weapons teams can be posted.

History
In 1998, the SDF-Navy searched for a cheap and reliable patrol vessels to protect the shores of the Free Lands from foreign illegal fishermen, smugglers and similar fiends, which resulted in the Fiagai-class Patrol Vessel, a small sloop in the tradition of the Miodóg-class Sloops. The first vessels were commissioned in 2004, working as coast guard and with the customs authorities, as administrative assistance, as well as keeping the trading routes safe, in other applications working as testbed vessels, tugs, radar pickets and other roles.
Around the same time, the Water Polices of the Free Lands searched for replacements for their ageing fleets, belaying a decision further down the road until 2014, some deciding to acquire Fiagais from the SDF-Navy, which were handed down from dissolved Patrol Gunboat Squadrons in the Naval Reorganization of 2016 (three boats found a new, loving home that way). Others decided around that time to approach Silverport Dockyards Limited with a Request for Proposal – the Corrán-class Offshore Patrol Vessel, less a military vessel and more a police vessel, also intended for the export market.
The first five units, sold to the Water Polices of Wembury, Tipa and Geata, were named Corrán, Stuama, Dubh, Marla and Gríosóir, all of which are characters of the aforementioned TV-show, Sicín Studios sending delegations to the commissioning ceremonies in 2017 and Corrán's Voice Actor, Finnegan Aisteoir of the Tribe of Wexford, a Servant of Gavida, holding the speech and devoting the vessel to its purpose.

St. Jimmy-class Library Vessel

Postby The Selkie » Mon Dec 04, 2017 1:06 am

Technical Data
Tonnage: 72,500 tons
Length: 240.6 metres
Beam: 28.6 metres
Draught: 7.3 metres
Complement: 650 crew, 300,000 books
Decks: 16
Propulsion:
    IEP, four diesel generators,
    2 azimuth thrusters, bow thruster.
Speed: 20 knots (37 km/h)
Sensors and Processing Systems:
    OEN, Navigation Radar.
The St. Jimmy-class Library Vessel is the result for a request of proposal of the Krimzon Guard to Silverport Dockyards Limited for a swimming library, that would be able to travel to ports to supply visitors with reading materials on a wide variety of matters.

Design
The St. Jimmy-class Library Vessel is a classical monohull-design, 240.6 metres in length, with a beam of 28.6 metres and a draught of 7.3 metres. At full load, it has a tonnage of 72,500 tons - please keep in mind, that the tonnage is not equivalent to the displacement!
Built of steel with an aluminium superstructure, the vessel has 16 decks, ten of which are accessible for visitors, and a crew of 650 sailors and attendants. Due to the nature of this vessel as a floating, moving library, there are no stewards and passenger rooms, thus reducing the operating costs and requirements.
The power for the vessel is provided by four Diesel Generators, providing a total of 30,000 kW of electricity to power the vessel and everything onboard - including the propulsion systems, two azimuth thrusters, which allow for great manoeuvrability, which is enhanced by the bow thruster. This allows for easy docking without the aid of tugs and similar vessels. The St. Jimmy-class Library Vessel has a maximum speed of 20 knots, or 37 km/h, with a range of 6,000 nautical miles.
The St. Jimmy-class Library Vessel is equipped with two Navigation Radars, both of them capable of being used as weather radars, a GPS-System and a Satellite Uplink System. In addition to that, the St. Jimmy-class Library Vessel is equipped with an onboard computer network, both for administrative purposes for the library and for entertainment of the crew on long journeys, should the library itself not be entertainment enough. This network is a standard OEN used on many of SDY's civilian vessels and accessible through every LAN-port as well as via WLAN, provided one has the necessary passwords.

The Library
Heart and centrepiece of the St. Jimmy-class Library Vessel is, of course, the Library, which is not a singular, large room, but all in all six rooms for different purposes. These six rooms are Main Library, the Collection of Antiques, the Children's Library, the Donation Centre and the Microfiche Centre.
The Main Library stretches six decks with an internal hollow space to allow viewing of the entire library, all four decks up and down, with entrances into the greenhouses and a large skylight to let natural light flood in. The lowest deck's central space is also a plaza, a free space usable in a variety of fashions, including as a dance floor, for assemblies and lectures. The Main Library alone has, according to estimates using the layout of the University of Silverport's Main Library as a reference, a storage capacity of around 300,000 books.
To store and preserve antique scriptures, the Collection of Antiques is equipped with the latest technology to store and preserve them, as well as to make them accessible for viewing by experts on the matter. A small laboratory to date and analyse new additions is by the side of the Collection of Antiques, which can also be used to house a small museum, if that is wished.
For younger readers, there is a Children's Library, soundproof and ready to receive smaller readers with their parents or caretakers. Rooms are set aside alongside that library to allow for groups of children to be read to without disturbing other groups or singular readers, with several reading corners set aside for the same purpose.
The Donation Centre is a relatively small area, where people can donate books to the vessel's library, which are then catalogued, checked for damages and, if necessary, repaired before being processed into the library itself – or handed out again. The computer terminals in the centre allow for easy access to the catalogue of the Main Library and the Donation Centre itself to easily find any book one might search for.
For research into the own ancestors, the St. Jimmy-class Library Vessel also carries a Genealogy Centre, an institute, where someone can research the own ancestors, both by genealogical records and by genetic research, a small laboratory added for this purpose. The ship carries the installations to have a digital genealogical database, as well as the ability to connect to other databases of the same kind for enhanced research, provided that the owners and holders of these databases grant access to them.
Last, but certainly not least, is the Microfiche Centre, where, as the name would suggest, microfilms are stored and can be viewed by interested people, thus granting access to old newspapers, documents, even artwork, if that is wished, all in the compact form of microfilms and their readers. The Centre includes a small workshop to produce own microfilms, as well as to repair damaged readers and films, a storage room for the films itself and a reader room.
Already mentioned, but not fully explained are the greenhouses: The topmost deck of the St. Jimmy-class Library Vessel is separated into a total of eight greenhouses, which can simulate a variety of environments. This serves to allow for a reading space 'in nature', as well as a place to teach gardening and agriculture to small and big future gardeners, independent from the weather. It also allows to showcase plants from the country of origin in a more natural environment instead of as potted plants. The water for usage on the plants is provided by the seas itself, after it had been made suitable for the task, namely by desalination – the same plant also provides fresh water to the vessel itself.

Aside from the Library
What isn't used as crew-space or technical space necessary for the operations of the vessel, or by the library and attached spaces, is used by the space for the additional functions of the vessel. Those include a theatre for movies, lectures and plays with 250 seats, and four smaller viewing rooms for movies with fifty seats each, all of which can also be used for entertainment movies.
The promenade deck in particular provides a space for relaxation and meditation about what had been read, including space for deck chairs and tables. One of the three cafeterias can serve an outdoor restaurant on the Promenade Deck as well.
In itself, the St. Jimmy-class Library Vessel has three cafeterias, each with their own kitchens and a central storage, including large refrigerators, and the capability to cook many dishes of the world's cuisine, depending on the abilities of the cooks and their helpers. One additional cafeteria is for crew use only.

History
The St. Jimmy-class Library Vessel began its life as Design 11052 of the Caillte Maritime Solutions Engineering Office of Wembury, a design for a cruise liner from the 80s, which went into SDY's possession as part of the inheritance of Fynn Caillte of the Tribe of Cork in 1993, who was married to SDY's CEO of today, Nora Cathlong of the Tribe of Cork - it was their daughter, Gwen, who adapted and finished Design 11052 to get the St. Jimmy-class Library Vessel.
It took more then twenty years for the plans to be taken out of storage, although updating and adapting took far less time. One part of the reason of Gwen Cathlong's fire when working on the St. Jimmy-class Library Vessel came from her being able to work with her late father's designs.
After numerous changes, and new proposals named the St. Jimmy-II- and St. Jimmy-III-classes for administrative purposes, the first vessel was laid down in late 2017.
Following her commissioning, she was sent on a world tour by the Krimzon Guard.

Pricing
One St. Jimmy-class Library Vessel without library: 325 million NSD.

Geabhróg-class Seaplane Tender

Postby The Selkie » Thu Feb 22, 2018 7:57 am

Technical Data
Displacement: 3,000 tons full load
Length: 125.5 metres overall
Beam: 14.45 metres
Draught: 3.6 metres
Propulsion:
    Integrated Electric Propulsion,
    1 Diesel Generator, 5,000 kW,
    1 waterjet
Speed: 18 knots
Range:
    6,000 nmi (11,112 km)
    at 12 knots (22 km/h)
Complement: 174, including mechanics
    Additional berthing for 150 people
Sensors and Processing Systems:
    Navigation Radar, Sonar,
    Digital Airport Surveillance Radar
Aircraft carried:
    Can carry, store and maintain
    up to two small seaplanes onboard,
    can support up to 24 seaplanes of varying
    sizes and types at the same time
The Geabhróg-class Seaplane Tender is a seaplane tender designed by Silverport Dockyards Limited for tending to seaplanes both close to the shores of undeveloped places, for example islands in the middle of nowhere, or places, where there's not the space for a regular airport or a shore-based seaplane port. Due to the shallow draught, the Geabhróg-class Seaplane Tender can operate very close to shore. This extends to both floatplanes and to flying boats.
While a military application of such vessels is not completely out of question these days, there are several hindrances to, for example the lack of military-grade sensors and processing systems or armament.

The term geabhróg means tern, the birds of the family of the Laridae.

Design
The Geabhróg-class Seaplane Tender is a classical monohull design with a steel hull and an aluminium superstructure, displacing 3,000 tons when fully loaded. The vessel is 125.5 metres long overall, has a beam of 14.45 metres and a draught of 3.6 metres, allowing the Geabhróg-class Seaplane Tender to operate even in shallow waters of undeveloped harbours and atolls.
The vessel has a range of up to 6,000 nautical miles, or 11,112 kilometres, at a speed of 12 knots (for details about the propulsion, please see below) under full load. For optimal function and operational capabilities, 174 crew members, including air crew, are required, while berthing for an additional 150 people is provided. Both crew and passengers are equipped with similar amenities, making the vessel very habitable, including amongst others a satellite uplink for telecommunications such as television and internet, as well as a Wireless LAN System with an integrated Onboard Entertainment Network.
Three dinghies can be used to make shore runs, either to ferry people or good to and from the shore or supply vessels. Please keep in mind, that these three dinghies are part of the delivery, up to six dinghies can be carried comfortably and without impairing aircraft operations.
In order to find underwater obstacles, the Geabhróg-class Seaplane Tender is equipped with a small sonar, which is to be used to avoid accidents. It can be used to detect fish swarms as well, but isn't particularly good at it.
Together with the Digital Airport Surveillance Radar, a Nuacht N-102 Mark II, a civilian cousin of the N-101 used on the Beag-class Aircraft Carrier and a far less powerful one as well, it completes the sensor suite of the Geabhróg-class Seaplane Tender. Said N-102 Mark II doubles as weather radar, navigation radar for when the vessel moves and can detect aircraft at 30 nautical miles or 55.5 kilometres, operating on the S-Band. Mounted on a mast, this radar consists of two major components, the detection radar itself and the beacon, which allows aircraft to follow it to the seaplane port or the Geabhróg-class Seaplane Tender.

For emergencies, the Geabhróg-class Seaplane Tender is equipped with a small hospital with thirty beds, including the small intensive care unit, and six water cannons with the option to spray firefighting foam onto their target. Other security systems onboard include a fire suppression system fit to work with flammable liquids and several storerooms locked with fingerprint scanners.

Propulsion
The Geabhróg-class Seaplane Tender is powered by a diesel generator providing 5,000 kilowatts of power, the same generators as they are used on board of the Port Hackburry class Fleet Oiler. These drive a singular waterjet for forwards motion with up to 18 knots and power all the electrical systems of the vessel, from the coffee maker to the radars.
The vessel is steered by this waterjet as well, eliminating the need for a rudder, which might get damaged by underwater obstacles. This is done by a technique similar to the one used on modern combat aircraft, namely thrust vectoring. The Geabhróg-class Seaplane Tender can also reverse by the usage of a reversing bucket.
The diesel generator and the propulsion arrangement reduce maintenance costs and increase both fuel efficiency and safety considerably as that arrangement eliminates the need for maintenance intensive gearboxes and secondary power generators.

Aviation Facilities
For Comparison: Seaplane Size Categories
(up to...)
Small Seaplane:
    Length: 10.5 metres
    Wingspan: 14 metres
    Height: 5 metres
Medium Seaplane:
    Length: 16 metres
    Wingspan: 20 metres
    Height: 6 metres
Large Seaplane:
    Length: 37 metres
    Wingspan: 40 metres
    Height: 12.5 metres
Everything above that is considered
a Very Large Seaplane
The Geabhróg-class Seaplane Tender can carry two small seaplanes onboard, as well as support up to 24 seaplanes of varying sizes and types, both with maintenance work, crew berthing, fuel and airport facilities. While the only limitations of the supported airplanes is the size of the area allocated to the Seaplane Tender, not the tender itself, the carried seaplanes are limited to the size specifications on the right.
The purpose of these seaplanes, from recreation, research, patrol, passenger and freight transport or any other conceivable or inconceivable application of seaplanes, matters little for the Geabhróg-class Seaplane Tenders performance, as its storerooms and workshops can work on many different kinds of equipment. For more extensive repairs of even a larger aircraft, a small crane with a maximum lift weight of twenty tons can haul an aircraft onto her large, open aft deck, which can double as a helicopter landing pad.
The fuel tanks can store up to 400,000 litres of aviation fuel, said tanks being double-hulled and highly secured. The eight different tanks can be filled with different fuels for different engines as well.

History
Seaplanes, ever since the first of them were invented, played an important role in the Free Lands, their tenders being important as well, naturally. With only two international airports and eight airports, bushplanes and seaplanes, as well as their pilots are important for the air traffic until today.
But back in time: The Geabhróg-class Seaplane Tender is the last iteration in a long line of seaplane tenders operated by Geabhróg Airlines, one of the first airlines of the Free Lands,

The Geabhróg-class Seaplane Tender, and it's first vessels, the Geabhróg herself and her three sisters, were the result of a request for development of Geabhróg Airlines, an airline of the Free Lands operating the seaplane services between the Mainland, the Archipelago and the Northern Islands, as well as several destinations outside of the Free Lands to replace a quartet of older vessels of the same kind.
In 2016, the Water Polices of Wembury, Dumhach and Conall Curach placed an order for three vessels in total to support their expansions into seaplane aviation in lieu of airports in their homecities and land-based aviation. The three vessels, Wembury's Breitheamh (Judge), Conall Curach's Bogaigh (Wetlands) and Dumhach's Réalta Dhorcha (Dark Star), their aircraft complements being partially financed by other water polices in exchange for shared usage rights, were delivered in 2017 and 2018, the last one being planned to be dubbed on the day of the Spring Festival 2018 in Silverport.

Pricing
One Geabhróg-class Seaplane Tender: 125 million NSD.

Pattern 263 Series of Cargo Vessels

Postby The Selkie » Fri May 04, 2018 7:40 am

The Pattern 263 Series of freighters is the result of a cooperation of Silverport Dockyards Limited with Avisronian technology firms, especially Lockwell Defence and the Avisronian Federal Energy Agency. The aim of the Pattern 263 Series was to develop an efficient freighter suited for either Dry Bulk and Liquid Bulk, capable of entering and operating in harbours of less developed nations, either conventionally powered or nuclear-powered.
The Pattern 263 Series is the first class of vessel in SDY's Catalogues, which exceeds the maximum length of 285 metres, which is the length of the main docks in Silverport, thus being constructed abroad: In Avisronia.
The aim was to develop a freighter hull, that can be built for different applications, namely as either a Dry Bulk and Liquid Bulk Vessel, differing in their engine compartments and technical details.
The Pattern 264 Series, following on this project, is the short-hulled version of that concept.
We highly recommend to operate vessels of the Models A and C with nuclear technicians onboard.

Pattern 263 Model A


Technical Data
Displacement: 65,000 tons (light)
Tonnage: 380,000 to 400,000 DWT
Length: 365 metres
Beam: 75 metres
Draught: 18.6 m (max.)
Installed Power:
    2 Lockwell Defence SR7 Nuclear Reactors,
    60,000 kW total
Propulsion:
    Single shaft, bow thruster,
    controllable pitch propeller
Speed: 29.5 knots (54.6 km/h, light)
Complement: 41
The Model A is the dry bulk carrying and nuclear-powered origin of the entire Pattern 263 Series, the initial hull to end all hulls. It was constructed as a part of the Pattern 263 Project, but its origins reach back to the days of the Caillte Maritime Solutions Engineering Office of Wembury, which went defunct in 1993, with their documents taken over by SDY as part of the inheritance of Fynn Caillte of the Tribe of Cork.
Like its fellow models, it is a classical monohull design built of steel with a double hull.
The reactor compartments, one on either end of the vessel, is armoured for security reasons, the Pressurized Water Reactors working in their basic principles like any other nuclear reactor, whether they are found on shore or other vessels. Their lifespan before the fuel needs to be changed is estimated to be around 30 years, but regular maintenance is highly recommended. The superstructure sits near the aft.
Due to their gigantic size, the Pattern 263 Model A is limited to deepwater ports or ports with offshore shiploaders, although the lightering of material to and from smaller vessels, like river barges, is a possibility as well.
Such deliveries are supported by a pair of two off-loading cranes, one before the superstructure, the other on the bow. These twenty metre high cranes, with a sixty metre long boom, can reach into every nook and cranny of the cargo holds.

Pattern 263 Model B


Technical Data
Displacement: 65,000 tons (light)
Tonnage: 380,000 to 400,000 DWT
Length: 365 metres
Beam: 75 metres
Draught: 18.6 m (max.)
Installed Power:
    Diesel generator, 30,000 kW
Propulsion:
    Single shaft, bow thruster,
    controllable pitch propeller
Speed: 16 knots (29.6 km/h, light)
Complement: 33
Model B is basically the same vessel as Model A, but with one important difference: Instead of being powered by nuclear reactors, the Model B is powered by a diesel generator, which provides less power, less speed and less costs for the owner, being cheaper in upkeep.
The Model B's diesel generator is mounted aft, below the superstructure. A heavy two-stroke crosshead Diesel generator provides all the necessary power, providing 30,000 kW of power for all ship operations, from the coffee maker to the single shaft. These engines, when run at their highest speed, consume around 100 tons of heavy fuel oil per day.
Due to the gigantic amount of cargo carried by one Pattern 263, however, the emissions in carbon-dioxide are lower then with a fleet of smaller vessels if calculated in emissions by ton of cargo.
There are a few other, smaller technical differences, like for example the Model B only carrying one crane, the bow crane, but in general, the Models A and B are similar to each other.

Pattern 263 Model C


Technical Data
Displacement: 65,000 tons (light)
Capacity: 500 million litres
Length: 365 metres
Beam: 75 metres
Draught: 18.6 m (max.)
Installed Power:
    2 Lockwell Defence SR7 Nuclear Reactors,
    60,000 kW total
Propulsion:
    Single shaft, bow thruster,
    controllable pitch propeller
Speed: 29.5 knots (54.6 km/h, light)
Crew: 45
Model C's life actually began by accident and by misinterpretation. Upon review of the plans, one of the engineers, originally working on the Pattern 256 Tanker, spoke about the cargo holds being tanks – while the Models A and B can be loaded with liquid bulk, they should not be loaded with liquid bulk.
That is, what the Pattern 263 Models C and D are for. Using that misinterpretation of the engineer as an inspiration, Yard 15 explored the possibility of indeed replacing the cargo holds with tanks, coming up with a design working quite well.
The Model C is the Nuclear-powered variant of the Pattern 263's Liquid Bulk Carriers, with two Lockwell Defense SR7 Nuclear Reactors at either end of the vessel, with twenty tanks having a capacity 500 million litres, or 3.14 million barrels, of either oil or gas.
For loading and offloading, the Model C is equipped with twenty cargo pumps, one for each tank, which can be connected to marine loading arms for loading and offloading.
Due to security reasons, the Model C is equipped with an inert gas system, which ensures, that the gas or oil onboard does not ignite by accident (which would be very, very bad), as well as tank cleaning system for each tank.

Pattern 263 Model D


Technical Data
Displacement: 65,000 tons (light)
Capacity: 500 million litres
Length: 365 metres
Beam: 75 metres
Draught: 18.6 m (max.)
Installed Power:
    Diesel generator, 30,000 kW
Propulsion:
    Single shaft, bow thruster,
    controllable pitch propeller
Speed: 16 knots (29.6 km/h, light)
Crew: 37
Model D is the Diesel-powered Pattern 263 Liquid Bulk Carrier, basically the same vessel as Model C with a diesel generator. With less power, less speed and less operating costs, the Model D has its reason for existence.
The Model D is equipped similarly to the Model C, with the major difference of the Model D having an own, crane-mounted marine loading arm, which enables the Model D to unload the cargo by itself, for when really no harbour or other facilities are available.
This also enables the Model D to be used as an oiler.

Pattern 263 Model E


Technical Data
Displacement: 65,000 tons (light)
Capacity: 300 million litres
Length: 365 metres
Beam: 75 metres
Draught: 18.6 m (max.)
Installed Power:
    Diesel generator, 30,000 kW
Propulsion:
    Single shaft, bow thruster,
    controllable pitch propeller
Speed: 16 knots (29.6 km/h, light)
Crew: 85
The Model E is the Floating Production Storage and Offloading Unit, developed from the Model D. It basically is a floating offshore oil refinery and storage tank.
Due to the need for technical equipment for refinery purposes, the rear tanks have been removed and replaced by said equipment, powered by the Diesel generator staying where it was. However, the engines do not produce enough power to power both engines and refinery equipment at the same time.
The Pattern 263 Model E has a production capacity of 25,000 barrels of oil per day and 4.5 million cubic metres of gas per day, a storage capacity of 300 million litres (or 1.88 million barrels) and can support four tanker offloading buoys, as well as draw oil or gas from eight well centres by injection lines.
Model E can be powered by a fraction of the own produce.

Pricing


One Pattern 263 Model A Dry Bulk Carrier: 750 million NSD.
One Pattern 263 Model B Dry Bulk Carrier: 80 million NSD.
One Pattern 263 Model C Liquid Bulk Carrier: 750 million NSD.
One Pattern 263 Model D Liquid Bulk Carrier: 85 million NSD.
One Pattern 263 Model E Floating Production Storage and Offloading Unit: 5 billion NSD.

The Siorc-class Diesel-Electric Submarine, or Pattern F-106, is one of the first submarines built by SDY, and in the Free Lands for that matter, in series, following a request for development by the SDF-Navy.
Specifically designed to counter nuclear-powered submarines, the Siorc-class Diesel-Electric Submarine is equipped with the most modern technologies in detection and avoiding detection, as well as computing of the collected data to the end of destroying the enemy while remaining undetected.

The term siorc means shark.

Design
The Siorc-class Diesel-Electric Submarine is constructed using non-magnetic materials, namely special titanium-alloys, whenever feasible and has a teardrop shaped hull for increased sub-surface performance. Sadly, this increased performance below the surface does not translate into an increased performance above the surface, where the vessel is considerably slower then below the surface. The hull is plated with rubber tiles, which further reduce the acoustic signature.
This increased sub-surface performance does not only mean speed, however, but also a decreased acoustic signature, which means a lower likelihood of being detected.
Steering is handled by two diveplanes on the sail, which assist with the rising and diving of the submarine together with the ballast tanks, while four rudders, arranged in cruciform behind the singular shaft move the plane to port and starboard.
Communications are handled via several masts, which can be extended out of the sail and back into it as needed or as surfaced, which includes a mast for GPS. A small Nuacht N-35 Mark III Submarine Navigation Radar Mast is used as a Navigation Radar, but can only be used on the surface.
On the topics of communications, which is generally very complicated to arrange with a submerged submarine, the Siorc-class Diesel-Electric Submarine carries a small buoy on a cable with a Very-Low Frequency receptor. The bandwidth between 3 and 30 kilohertz can penetrate water to some very short extend, but, due to the size VLF-Senders need, the submarine can only receive such signals and not send – a transmitter site is needed to sent messages.

Propulsion
The Siorc-class Diesel-Electric Submarine is primarily powered by two Diesel-Electric Engines, which rest on shock-absorbers to reduce the noise of their operation, powering all electrical systems onboard the vessel, mainly however the engines power the one shaft driving the submarine forwards.
In addition to that, for silent running, the Siorc-class Diesel-Electric Submarine is equipped with four Alpha-Type Stirling Engines. Heat for this type of engine is generated by burning the same diesel with an oxidizer, usually liquid oxygen, which enhances the heat output of the diesel and thus allows the engines to generate power at a noise level far below that of the diesel generators.
While the Stirling Engines can only produce a fraction of the power the Diesel-Electric Engines can, thus resulting in for example a much lower speed when only using the Stirling Engines to power the submarine, they are next to absolutely silent.
In total, all engines combined, can produce up to 6,000 kW of energy, which allow the Siorc-class Diesel-Electric Submarine to travel at 13 knots, or 24 km/h, when surfaced, submerged at 20 knots, or 37 km/h, and 5 knots, or 9.3 km/h, on the Stirling Engines alone.
The Siorc-class Diesel-Electric Submarine is estimated to have a range of 6,100 nautical miles, or 11,300 kilometres, on the Stirling Engines and can stay underwater for at least two weeks before needing to surface.

Sensors and Processing Systems
The Siorc-class Diesel-Electric Submarine is equipped with a highly advanced sonar suite, comprised of five arrays, one on the bow and four on the flanks. These arrays can be used in active and passive modes, either listening to emissions from other vessels, both on the surface and below, or sending out emissions themselves while listening. Due to their extremely sensitive structure and architecture, these arrays can detect smallest of noise emissions from miles away and also feature a torpedo alert.
In addition to that, the Siorc-class Diesel-Electric Submarine can deploy a Towed-Array Sonar with many of the same characteristics.
For the detection of the radiation emissions of nuclear-powered vessels, and despite any assurances of the producers, there are emissions, the Siorc-class Diesel-Electric Submarine carries a Geiger Counter Array, which analyses the radiation around the submarine and assigns it to sources of radiation, determining the origin, thus finding out, whether or not there are enemy nuclear powered vessels, be they other submarines or surface vessels, in the general area.

Electronic Warfare Equipment and Decoys
The Siorc-class Diesel-Electric Submarine is equipped with a suite of Electronic Support Measures, ESM for short, which allow to detect, intercept, identify, record and locate electromagnetic energy, for example radar, and be used to draw conclusions based on these data for operational planning, tactical decisions and other purposes. ESM, however, does not mean deciphering enemy transmissions. Part of this suite is a Radar Warning Receiver, which tells the submarine when it has been spotted by radar.
In addition to that, the Siorc-class Diesel-Electric Submarine carries six launchers for acoustic decoys, which can be used to throw enemy units and torpedoes off the submarine's track. Basically noisemakers, these decoys lure sonars into believing, that the submarine is where the decoy is and not where it actually is.

Armament
The Siorc-class Diesel-Electric Submarine is armed with six 533 millimetre torpedo tubes, capable of being loaded with torpedoes, missilesm unmanned underwater vehicles, usually of the wire-guided variant, and be used by frogmen as an exit.
SDY already tested Type 40 and Type 43 Anti-Ship Missiles and Type 50 Cruise Missiles with these tubes, resulting in positive tests. Depending on the exact loadout, the Siorc-class Diesel-Electric Submarine can carry up to 36 shots, six of which are already in the tubes.
In addition to that, the Siorc-class Diesel-Electric Submarine can be used to deploy mines.

History
Contrary to popular belief, there had been submarines built by SDY before: From a number of prototypes and design studies to a series of research submarines and even a submarine yacht, the Bradaí, as well as a few conversions, we gathered quite an experience.
None of those designed for military service ever really took off or was produced in larger quantities, neither for the SDF nor for export customers. Yard 15 still had a number of submarine construction experts on staff for exactly that reason.
But all of that changed with the Battle of Marley Bay, when the SDF suffered catastrophic losses at the hands of the enemy. In the Naval Expansion Programme of 2013, the development of a number of submarine types was contracted to SDY and other shipyards in the Free Lands in order to give the SDF weapons, which they could use to defend the Lands and their political interests abroad.
From 2013 to 2015, several lists of requirements were made and several designs to match them, with Patterns F-100, F-106 and F-109 being finally selected (F stands for fomhuireán or submarine) by the SDF with Patterns F-105 and F-110 continued by SDY for the export market.
Pattern F-106 would become the Siorc-class Diesel-Electric Submarine, with the first unit, SDFS F-16 Siorc, launched in late 2017 and beginning sea trials. She was commissioned in 2019 with several sisters to follow.
The Pattern F-106 is the first submarine constructed in the Free Lands to use an Air-Independent Propulsion System based on a Stirling Engine.

Pricing
One Siorc-class Diesel-Electric Submarine: 535 million NSD.

The Dair-class Fisheries Research Vessel is the newest vessel in a long line of research vessels built by Silverport Dockyards Limited. Optimized for Fisheries Research, the Dair-class Fisheries Research Vessel can also be used in other Hydrographic research, for example undersea-mapping, or research on marine life in general.

Design
The Dair-class Fisheries Research Vessel is a classical monohull-design built of steel, 66 metres in length, 14.6 metres in width with a standard displacement of 2,500 tons and a maximum draught of 5.3 metres. Six decks give enough work and living space for a crew of 14 men and up to 22 scientists and/or students.
Scientists and students share the mess hall with the sailors, providing a unique experience for the students, who learn not only about their subject matter, but also about those regularly working on their subject matter. The mess hall can easily be converted into a number of different functions, from a cinema, to a lecture hall to a makeshift sickbay and many more functions (to celebrate the commissioning of Dair, the mess hall was converted into a ball room).
The hull is reinforced to handle ice, but is not to be used as an ice-breaker.

A Diesel Generator, providing 4,000 kW of electrical power, is used to give the vessel the energy it needs to operate, from the sensors to the pump-jets to the coffee maker. Although the generators, the same as used on the Scoth-class Corvettes used by the SDF-Navy, are very reliable, the vessel also carries an Emergency Diesel Generator rated for an output of 1,000 kW, which can power the vessel in case of generator failure or simply more power being needed. Both generators are rested on shock-absorbers to reduce the acoustic emissions for both reduced fish-avoidance and increased crew comfort.
Propulsion is handled by two pump-jets with vectored thrust capabilities, including reversing by bucket, allowing the vessel to attain speeds of up to 16 knots, or 29.6 km/h, resulting in high manoeuvrability and low acoustic emissions. A bow-thruster makes docking easier and omits the need for a tugboat.
In its whole, this arrangement is also known as Integrated Electric Propulsion, or IEP for short, which saves maintenance costs and space aboard.

The Dair-class Fisheries Research Vessel has provisions to stay at sea for up to 35 days.

Sensors
The Dair-class Fisheries Research Vessel is equipped with a multitude of sensors, one of them being a navigation radar, more precisely a Nuacht N-4 Navigation Radar, used on a variety of vessels of all sizes built and maintained by SDY.
Foremost amongst the other sensors is a Fisheries Sonar, a small, yet capable device optimized for finding fish. Due to sound travelling differently through fish then through water, the reflection of that sound, or Ping, can be used to detect schools of fish or other sea-dwellers, thus allowing for locating these, observation and other measurements, for example density of the swarm. The Fishing Sonar is unsuited to find submarines.
Another important suit of sensors is a set of two Multi-Beam Echosounders, which can be used to map the ocean floor for navigational purposes. The range of these Echosounders is rated as up to 5,000 metres below the waves.
In addition to those systems, the Dair-class Fisheries Research Vessel is equipped with a suit for Meteorological Research, thus weather prediction.

For the application of the most powerful sensors naturally available to the human eye, however, the Dair-class Fisheries Research Vessel is equipped with a Crow's Nest: The Crow's Nest, or crannóg, is a small post at the top of the main mast, which is equipped with a number of optical instruments, from telescopes to cameras, including night-vision and infrared vision modes, as well as a position for a person or three to stand and made own observations using binoculars.

Other Equipment
The Dair-class Fisheries Research Vessel is equipped with a number of systems for more direct research and positioning. One of them is a Dynamic Positioning System, which allows the vessel to hold position despite waves and currents by using the own engines to keep position.
For getting material, be it
Work aside from the vessel can be done by up to three Remote Operated Vehicles, or ROVs, for which deckspace is set aside, as well as up to two dinghies or workboats, neither of which are included into the delivery (we recommend the Majestic-class Boat as a workboat). We recommend, that none of these ROVs or workboats is heavier then twenty tons, the maximum lift weight of the two cranes, the same ones as used on the Geabhróg-class Seaplane Tender. The cranes can also be used to lift cargo or equipment on and off of the vessel.

Sternwards, the Dair-class Fisheries Research Vessel is equipped with an A-Frame, which can be used to recover smaller craft or a trawl for sampling.
To analyse these samples, and other data, the Dair-class Fisheries Research Vessel is equipped with Laboratory Space. 75 square-metres are allocated to Dry Laboratories and 70 square-metres are to be used for Wet Laboratories, which can be expanded by fixing up to five containers onto the deck, without limiting the remaining deck-space.
Additional samples can be collected by a Seawater Intake System, stored in tanks big and small, together holding 5 cubic-metres of fluids. A fish sorting area is connected to the largest tank to collect living samples and to keep them alive.
The Dair-class Fisheries Research Vessel is also equipped with the most advanced computer systems available for the civilian market, a Type 901 Datalink (a close cousin of the Type 900 Datalink) linking all scientific instruments aboard together, including the possibility of linking personal computers into the network. That system can also be used for entertainment purposes, but is not designed as such.

History
As people living with and on the seas, fishery has always had a very important role for the Selkie, one which did not change over time and space. Our cuisine, which knows many fish-dishes, our myths, which involve the seas in many ways, those and more reflect that.
As such, fisheries research has also traditionally played an important role within history and with the
Enter the Trosc-class Fisheries Research Vessel, being planned by Caillte Maritime Solutions Engineering Office of Wembury with three units built by SDY and in service from 1986 to 2013. These small vessels, around 40 metres in length, provided the oceanographic research institutes of the Free Lands with the vessels they needed to conduct research and to train their youth. One of those vessels was sold to another nation in 2001, the other two were decommissioned by 2013 – and the search began anew.
While the SDF-Navy procured their own vessels to do the job, the scientists were always a bit sceptical of going to the Navy for their research materials, always searching for alternatives (the Caorthann not being one due to the Caorthann being a Polar Research Vessel) and, by 2016, having that alternative greenlighted: The Pattern 297-T, based on the Pattern 297 Fishing Trawler, or, as she is known today, the Dair-class Fisheries Research Vessel.
With the first vessel, Dair, being launched in late 2017, being commissioned in May 2018, the marine research institutes of the Free Lands finally had an own vessel of substantial size again, soon to be followed by two more.

Pricing
One Dair-class Fisheries Research Vessel: 25 million NSD.
If ordered by a research institute of a university or school, the Science Discount is in effect, reducing the cost to 23.75 million NSD.

SDY-Greadtóir 15 Craiceáilte Mark I Attack-VTOL

Postby The Selkie » Sat Jun 02, 2018 2:52 am

Technical Data
Length: 17.5 metres
Width: 14.8 metres
Height: 4 metres
Weight:
    Empty: 6.1 tons
    Loaded: 10.4 tons
    Maximum Takeoff: 10.5 tons
Maximum Speed: 600 km/h
Range: 1,600 km (without additional fuel tanks)
Combat Radius: 450 km (full aerial combat)
    Strike Radius: 750 km
Crew: 1
Armament:
    30mm autocannon (1000 rounds)
    8 hardpoints (2 internal, 6 external)
The SDY-Greadtóir 15 Craiceáilte Mark I Attack-VTOL, known as the Kyrenaian Aircraft Factories KAF-125 Nasir VTOL in services of the Royal Kyrenaian Navy, is a Vertical Take-Off and Landing Attack Craft designed by SDY-Greadtóir and KAF for the Royal Kyrenaian Armed Forces and the SDF in order to provide an Attack-VTOL for use aboard the Sealgaire-class, the Ceasia-class Escort Carrier and similar vessels, as well as on land.
Like its name suggests, it is a crazy little craft.

Design
Overview
The Craiceáilte Mark I Attack-VTOL is a small craft, 17.5 meters of length and four meters high. The entire construction weights 6.1 tons with a loaded weight of 10.4 tons, at which the Craiceáilte Mark I Attack-VTOL has a range of 1,600 kilometres without additional fuel tanks on transfer flights with a strike radius of 750 kilometres, but can be refuelled in air.
The aircraft can reach a maximum speed of 600 kilometres per hour.
Manned by one pilot, the Craiceáilte Mark I Attack-VTOL needs a ground crew of experienced mechanics and personnel, which can maintain the modular aircraft in all of its complexity. And complex, as well as maintenance intensive, it is. Modular parts are the wings, and the fans in them, as well as the tail assembly, the nose (and the radar within it) and the carriage.
The main fuselage houses the cockpit, the engines, electronics, fuel tanks, the internal hardpoints and the control systems.
A main design feature is the NOTAR-Assembly, which foregoes a tail rotor in favour of two contra-rotating ducted fans in the 'wings'. Instead, the tail assembly has control surfaces, especially ailerons and elevators, a fuel tank and a magnetic anomaly detector. The wings with the fans are capable of wing-warping for more agility.
For self-defence, the Craiceáilte Mark I Attack-VTOL carries two dispensers for chaff and flares, acting as countermeasures against guided missiles. The internal hardpoints can be equipped with ECM-pods and other countermeasures.

Sensors
As mentioned before, the sensors of the Craiceáilte Mark I Attack-VTOL are manyfold, a radar in the nose and a magnetic anomaly detector in the tail assembly.
The radar is a capable and proven Nuacht N-26 Mark II X-band Pulse Doppler Radar, the same as on the SDY-Sciathan 18 Stuama Mark II Light Multirole Fighter, with an effective scanning range of sixty kilometres looking up, capable of tracking twelve targets at that range.
In the tail assembly, the Craiceáilte Mark I Attack-VTOL carries a Magnetic Anomaly Detector, MAD for short, a magnetometer to detect minute variations in the Earth's Magnetic Field, usually used to detect and ultimately sink submarines. The MAD usually rests within the hull, but must be extended when in use, although the device is hampered by the distance to the target and the depth of the target. These sensors can also be used on land to detect magnetic anomalies. Both devices rely on the content of ferromagnetic materials in the target.
A radiation detector provides further reconnaissance information, with said information used to locate and destroy enemy nuclear-powered submarines and surface vessels as well as similar land assets.
In addition to that, a downsized battlescape network system enables the Craiceáilte Mark I Attack-VTOL to send and to receive data from other aircraft, ships, land units and other sources without problems, without the need for a node, although that would increase the performance.

Engines, Controls and Handling
The power of flight is provided to the Craiceáilte Mark I Attack-VTOL by two contra-rotating ducted fans, who, in turn, are powered by two free-turbine turboshaft engines, both of them Luas L-92 Mark III Free-Turbine Turboshaft Engines, distant relatives of the L-91 used on the SDY-Greadtóir 19 Cuaifeach Shipborne Helicopter. These turbines, in principle close to jet engines, but actually differing in so far that they optimized for providing shaft power rather then thrust, are highly reliable, small, relatively light and can provide a high power output. In this case, each of these engines can provide up to 2,300 shp.
Sitting at the side of the fuselage, the L-92s provide power to the Craiceáilte Mark I Attack-VTOL, in the forms of lift, forward movement and a bit of electricity. The aircraft can rise like a helicopter, even with full load, and manoeuvre by wing-warping, providing it with a manoeuvrability unseen so far. Due to the rotors being ducted fans, the losses of thrust by air turbulences at the tips of the rotors are eliminated (not to mention the noise), with more and shorter propeller blades operating at higher rotational speeds, being safer for ground crews as well.
The pilot, supported by a HUD, sits in a glass cockpit, which allows him to steer the aircraft by triple-redundant fly-by-wire systems, modular in architecture to ease maintenance.
A trainer with two seats, but without rear weapons bay and heavily reduced capabilities, is offered as well.

Armament
The Craiceáilte Mark I Attack-VTOL is equipped with a retractable 30mm autocannon with a thousand rounds underneath the nose, directly controlled by the pilot on a pivoting mount. The pilot controls the gun either by a small joystick or via the HUD and eye movements.
In addition to that, the Craiceáilte Mark I Attack-VTOL has eight hardpoints, two internal and six external. The two internal hardpoints are limited to either equipment modules, like an ASW- or an additional ECM-suite, or barrel bombs, depth charges and similar weapons. The six external counterparts can be armed with many kinds of weaponry, from rockets to missiles to further gun modules.

Stealth
The Craiceáilte Mark I Attack-VTOL is constructed with a reduced radar signature in mind, but that was not at the forefront of the development. It is most suited for operating in low altitudes, so radar detection will be difficult to begin with. However, it is not a stealth-craft.
Hearing the Craiceáilte Mark I Attack-VTOL is not as easy as with for example helicopters: A conventional helicopter is far louder, mostly due to rotor noise, the famous Whump-noise, which does not occur with the Craiceáilte Mark I Attack-VTOL, due to the ducted fans. There still is noise, but it's not as much as with helicopters.

History
In 2000, with the introduction of the Luaith Attack Helicopter, it became apparent, that these helicopters did little in the way of aiding the SDF-Army in its tasks – quite on the contrary, with their harsh maintenance requirements and specialized equipment, they were more of a burden. In 2010, they exceeded their repair budget so far, that by October, the fleet was force-landed and the Army began to search for a replacement, including straying into the world of VTOLs. It wouldn't be the first time, that the SDF considered VTOLs for service, but the first time, that a VTOL was introduced into service.
In 2012, after the disastrous Battle of Marley Bay, the SDF-Navy joined the development effort, including a version for their new aircraft carriers, at the time still being presented with a choice between the Sealgaire-class Helicopter Carrier and the Beag-class Aircraft Carrier. Both are now part of SDY's Catalogue, although only the former was adapted by the SDF-Navy.
The SDF-Navy showed great interest in the Craiceáilte Mark I Attack-VTOL, the Army still wishing to adapt them for their service to replace the Luaith Attack Helicopters. Slowed down by troubles with the handling and the engines, the planned introduction date in 2015 passed without the introduction of the new aircraft.
Searching for a new VTOL for the Royal Kyrenaian Navy, to support landings of the Fleet Marine Forces, the Sultanate joined the programme in 2013, giving it the local designation KAF-125 Nasir.
Getting the controls under control proved to be easier said then done, but it was managed in 2016.
In 2017, the first Craiceáilte Mark I Attack-VTOL rolled out of the factories, training and shakedown beginning in July aboard the Helicopter Carrier SDFS Maor, with official flight operations starting on March 20, 2018, the Day of the Spring Festival.

Pricing
One Craiceáilte Mark I Attack-VTOL: 45 million NSD.
One Craiceáilte Mark I Attack-VTOL Trainer: 35 million NSD.
One squadron of twelve Craiceáilte Mark I Attack-VTOLs: 525 million NSD (including support by engineers, initial service and crew trainings).

SDY-Sciathan 20 Guairdeall Multi-Purpose Amphibian Aircraft

Postby The Selkie » Sat Jun 02, 2018 2:53 am

Technical Data
Crew: Depends on model
Length: 32.3 metres
Wingspan: 32.8 metres
Height: 8.95 metres
Wing Area: 120.9 square-metres
Empty Weight: 25.3 tons
Maximum Takeoff Weight:
    Water: 38 tons
    Land: 41.3 tons
Powerplant:
    2x Luas L-36 Mark IV Turbofan Engines
    with 75 Kilo-Newton maximum thrust
Maximum Speed: 700 km/h
Range: 2,500 km
Service ceiling: 8,000 metres
The SDY-Sciathan 20 Guairdeall Multi-Purpose Amphibian Aircraft is a large amphibian aircraft designed by SDY's Subsidiary Sciathan Limited as a Multi-Purpose, all-weather, all-environment aircraft, capable of acting as a firefighting aircraft, passenger or cargo hauler, maritime Search and Rescue, maritime patrol, Anti-Submarine Warfare and other roles.

The term guairdeall means petrel, as in the birds of the order Procellariiformes.

Design
The SDY-Sciathan 20 Guairdeall Multi-Purpose Amphibian Aircraft is a high-wing T-tail monoplane with two turbofan engines mounted above the fuselage on the wings' roots.
The fuselage features a high length-to-beam-ratio, which makes the aircraft easier to control in water, and a small rudder. One floats at either end of the wing allow for swimming.
Equipped with triple-redundant Fly-by-Wire Systems and digital displays, the SDY-Sciathan 20 Guairdeall Multi-Purpose Amphibian Aircraft allows for easy maintenance and simple controls, as well as allowing for modern navigational systems, including GPS, an autopilot and a weather radar. The glass cockpit allows for one pilot to be able to fly the aircraft safely, but we recommend a cockpit crew of two people.
The supercritical wings have a sweep angle of 25 degrees, which allows for easier take-offs and landings.

The aircraft is powered by two Luas L-36 Mark IV Turbofan Engines, highly modern engines capable of providing a maximum thrust of 75 kilo-newtons, which were built using corrosion-resistant materials. It is a three-spool high bypass turbofan engine, optimized for fuel economy. The engines are equipped with Full Authority Digital Engine Control Units, FADEC Units for short, which provide a better fuel efficiency, protect the engines against out-of-tolerance operations and provide a number of other advantages. Combined with the titanium blisks, which integrate both the blades and the compressor disks into a single part, the efficiency of the engine is higher then that of normal compressor disks and blades attached to them by elimination of the bolts and screws holding everything together, thus eliminating drag and the number of components.
The Luas L-36 Mark IV is not exactly easy to maintain, both due to the weight of the engine of one and a half tons and due to a few components' availability, but it can be done by skilled mechanics with relatively little effort.

As an amphibian, the SDY-Sciathan 20 Guairdeall Multi-Purpose Amphibian Aircraft can operate from both prepared airstrips, unprepared airstrips and from the surface of the water, making it an ideal large bush plane. To that end, the SDY-Sciathan 20 Guairdeall Multi-Purpose Amphibian Aircraft usually comes equipped with larger tyres, which allow for operations from rough terrain.
The SDY-Sciathan 20 Guairdeall Multi-Purpose Amphibian Aircraft can safely take off from a runway 1,800 metres in length or a stretch of water 2,300 metres long with waves up to 1.3 metres high, including safety clearances and when loaded to capacity.
Both the wings and the T-Tail, as well as the engines, can be detached for ease of maintenance and storage. All SDY-Sciathan 20 Guairdeall Multi-Purpose Amphibian Aircraft feature aerial refuelling capabilities.

Guairdeall Model C – The Civilian
Model C is the most basic variant, a classical amphibian floatplane capable of either hauling cargo or passengers around the countryside. The pressurized cabin allows for up to 72 passengers and their luggage, with the seats easily removable to convert the Model C into a cargo hauler capable of carrying eight tons of freight. A combination of both is possible as well.
Crewed by two pilots and with little else, Model C is a classical amphibian, which can also act as a bush plane.

Guairdeall Model FFT – The Flying Firefighter Team
Model FFT is the firefighting-model of the SDY-Sciathan 20 Guairdeall Multi-Purpose Amphibian Aircraft. Incapable of carrying passengers, but eight aluminium tanks to store water for the purpose of dropping it onto a fire. The four scoops can fill the tanks, which can hold up to 12,000 litres or 12 tons of water, in 14 seconds from any longer stretch of lake, river or the sea itself. In addition to those eight tanks, four smaller tanks with a capacity of 1.3 cubic metres can be used to transport fire-retarding chemical agents and similar substances.
The tanks can be emptied in up to 1.5 seconds over the site of a fire.
The tanks can be removed to make space for cargo, but converting the Model FFT into a passenger plane is harder. Three to four men crew the Flying Firefighter Team.

Guairdeall Model S – The Rescuer
Model S is the SAR-Variation, coming equipped with a small boat, searchlights, a surface-search radar, thermal and optical surveillance systems, the latter including night vision modes, as well as medical equipment. Aim is to assist vessels in distress, salvage crew and passengers of vessels or aircraft having gone down at sea.
Two pilots and up to six rescue personnel crew the aircraft, with seats for forty rescued people and six stretchers. Alternatively, up to 36 stretchers can be taken along, making the Model S an airmobile hospital.
The S stands for sábhálaí, which means rescuer, fitting for a Search and Rescue Aircraft.

Guairdeall Model F – The Hunter
The Model F is the only variation with a military role in mind, namely maritime patrol, surveillance, including pollution control, and Anti-Submarine Warfare. Equipped with a variety of new sensors and systems, amongst them an Air/Surface Search Radar, a Magnetic Anomaly Detector, an ESM- and an ELINT-Suite, an Artio Battlescape Network Mark IV-L and the capability to carry and to deploy sonobuoys in an internal bomb bay, as well as other weapons to fit in there, this aircraft has to be crewed by two pilots, a bomb bay master, as well as six sensor technicians and a computer technician.
The radar, a Nuach N-48 Mark III, is a pulse doppler radar employing frequency hopping and control of the side lobes in order to be harder to detect, which can be used as an AWACS-Radar to detect low-flying and surface targets at a range of 400 kilometres, while a second radar, a Nuach N-26 Mark II X-Band Pulse Doppler Radar, the same one as used on the SDY-Sciathan 18 Stuama Mark II Light Multirole Fighter, is employed as an air-search radar. Both radars employ modern onboard computers to even pierce through the shroud of stealth. The radars are housed in a radome at the underside of the aircraft near the bow, which can be accessed from above.
A Magnetic Anomaly Detector, MAD for short, mounted on a rear boom, can be used to detect minute variations in the Earth's magnetic field, for example due to a mass of ferromagnetic materials, like submarines, being below the surface. Despite assurances of the contrary, ferromagnetic materials are needed in submarine construction and while the MAD has a very limited range, it is still a very viable method of searching for a submarine.
The Model F is also equipped with an ECM- and an ESM-suite, providing capabilities in Electronic Warfare. Electronic Countermeasures allow to trick and deceive enemy sensors, allowing to actively jam enemy radars and radios. ESM, Electronic Support Measures, on the other hand, allow to detect and identify, as well as analyse and record radiated electromagnetic energy, for example by radar, for threat recognition and identification and operational planning.
All that data collected by the sensors can be shared with other aircraft, vessels, command posts and ground stations via an Artio Battlescape Network Model Mark IV-L, which also allows the Model F to act as a network node – we, however, do not recommend that.
The Model F is also equipped with chaff and flare dispensers in the floats.

The internal bomb bay can not only be used to carry sonobuoys, but also for housing depth charges, naval mines, torpedoes and missiles, mostly anti-ship missiles and other large missiles. The Model F is capable of carrying both Type 40 and Type 43 Anti-Ship Missiles. Additional pylons under the wings can also carry additional fuel tanks and weaponry.

The F stands for fiagaí, which can mean hunter, fitting for an ASW-Aircraft.

History
Passenger Aviation in the Free Lands, as a quicker alternative to railway travel, has a history and especially with floatplanes and amphibians. It quickly took off, quite literally, and bush aircraft, which could operate everywhere (or nearly everywhere), had the major role in that traffic. The railway system still had and has its place, but air traffic by amphibian is important as well.
It was from that standpoint, that SDY-Sciathan began with the development of a large amphibian in 2010, to replace the ageing fleets of larger bush aircraft in the Free Lands and to fill a number of other, sorely needed, civilian roles like airborne firefighting and Maritime Search and Rescue.
In the meantime, the SDF also came to the realization, that they needed to replace their old fleet of their Sneachta Naval Reconnaissance Plane and Submarine Hunters and Ulóg Transport Planes – and found the SDY-Sciathan 20 Guairdeall Multi-Purpose Amphibian Aircraft to be a fitting replacement for either aircraft.
After the first flight of Model FFT in the summer of 2016, it was quickly put to good use, as the Great Woods were ravaged by a forest fire. With other prototypes of the Guairdeall, as well as older aircraft, the fire was brought under control, but was finally put out by engineers of the SDF-Army and the Younger Militias.
In 2018, the Guairdeall was unveiled at the Olgean Arms Expo and international marketing started.

Pricing
One SDY-Sciathan 20 Guairdeall Multi-Purpose Amphibian Aircraft Model C: 20 million NSD.
One SDY-Sciathan 20 Guairdeall Multi-Purpose Amphibian Aircraft Model FFT: 40 million NSD.
One SDY-Sciathan 20 Guairdeall Multi-Purpose Amphibian Aircraft Model S: 25 million NSD.
