Description
The Noble-class carrier is an extensive refit to the older Citadel-class carrier. While still quite similar in outer appearance, the Noble fixes internal problems not foreseen with the Citadel and creates an entirely more streamlined lifestyle for the crew. In addition come more advanced and better ventilation systems. The entire ship maintains heating and air conditioning systems suited to maintaining a comfortable living condition in any environment the world has to offer it, as well as better particulate filtering and dehumidifiers.

Coming from the Citadel's success with the six-elevator, six-catapult, two-trap system, the Noble still uses a centerline island, but utilizes a larger bridge to make up for the sacrificed space from utilizing the flight deck for island space. The windows on the island also allow for old-school visuals of the flight deck in addition to the many cameras. The added two elevators are necessary in assisting in moving aircraft about the flight deck during Flight-Operations (FLOPS), taking into consideration the ability to land twice as many aircraft as a typical carrier while also launching the same volume as it's predecessors. These covered elevators also provide an added degree of protection from both enemy munitions and prying eyes, allowing for normal flight-deck preparations to be performed relatively outdoors and rapidly launching the aircraft from a safe location, in the event of war, high-seas, or a black-operation.

In addition, each of the external elevators sports a crane which can reach as far out as seventy-feet from the edges of the boat, and as far in as near the center-line of the carrier, where cargo can be rapidly transported by internal ceiling-bound cranes or mobile cranes. The crane's support arms are imbedded beneath the flight-deck, fixing it in place. In the event of a failure of the primary and secondary hydraulic locomotive drives of the elevators, the crane can act as a tertiary lift, albeit slow. Unlike the Citadel, this crane is far better protected and it's support more internal.

The propulsion system itself is the largest advancement; the addition of a new azipod aft - meaning that the two most centerline azipods do not maintain a full range of motion - as well as using the same engines for six internal engines, allowing for speeds that would normally be considered ridiculous for carriers so large. The six internal engines have some vectoring to their discharge as well, allowing for lateral motion of the carrier, allowing for docking without tugboats and for increased maneuverability. The azipods themselves allow for turning so drastic that, were the Noble not trimaran, it would cause severe listing.

Ideal aircraft complement is denoted as being 118 aircraft; the ideal figure includes allowances for several COD aircraft, AWACS, and eight to twelve helicopters, the remainder of aircraft expected to be fighter-sized.

A3H1 Pressurized Water Reactor
A: Aircraft Carrier
3: 3rd Generation
H: Halcyon Arms
1: 1st Iteration


The A3H1 is a Pressurized Water Reactor utilizing nuclear fission for the purpose of heat production to be used to create steam for usable work. The A3H1 is jointly designed by Halcyon Arms and Asimov Engineering, and built by Halcyon Arms. Core life is expected to be twenty years, depending on operations, maintenance, and modifications made. Utilized for only electrical power, the core may last for up to 60 years, and made it's debut on the Noble-class The reactor core is rated to 875 MW production capacity and utilizes highly enriched uranium as fuel. The Uranium is made into uranium oxide pellets which are then clad in zircaloy to make fuel-plates, which are stacked with gaps between them (for coolant to pass through), and made into assemblies, which are then assembled around a center channel design for the control rod to pass through, making a fuel assembly. This fuel assembly is immobile within the core.

The A3H1 is a two-loop reactor plant design, using highly pressurized and purified water as both coolant and moderator. The heated coolant passes through a boiler unit, heating it's water to produce steam. This water is then pumped back to the core by a reactor coolant pump, one per loop, where it passes around the reactor vessel, mixing with water from the other loop and then through a colander to ensure proper mixing of the coolant and filtration of debris, should any exist. From the colander the water passes up through the first-pass fuel channels for the initial heating, then out, around, and down the fuel assemblies to again pass upwards through the second-pass fuel channels, heating up the coolant further before ejecting it into the outlet region, where the coolant is sent back through towards the boiler units. The boilers provide steam for five turbine generators, two of which are used to power the reactor coolant pumps, and the other three powering the Common Electrical Distribution System.

Due to using water as a coolant/moderator, the reactor achieves natural stability. If the reactor experiences an up-power transient the coolant heats up further it will be less dense and moderate fewer neutrons, so more neutrons will escape the core, again lowering reactor power back to it's original state. The only process, therefore, which will change reactor power and maintain it steady-state at that new power is a change in steam-demand, save for massive introductions of poisons which drive the reactor out of it's power range, such a protective "Scram". Conversely, other factors can change temperature, namely the introduction of poisons, to include control rods. Control rods are used for reactor control as well as protection; in the event of a loss of power they will automatically scram (insert to the bottom of the core, shutting it down completely). This can also be done by the operator or by automatic action in the event of other casualties as well. Additional safety features include automatic filling of the reactor, should the core become depressurized and risk becoming uncovered, which would mean a lack of coolant and would allow for potential meltdown. With this, significant release of fission-product contamination external to the hull of the ship is guarded against.

The A3H1 is capable of operating up to 10% power without powering it's reactor coolant pumps; this natural circulation can be used for both decay heat removal and low power operations, making the reactor plant relatively quiet, but this natural circulation also provides for power transient-response and is not suitable for combat operations. As they are easy to cool without operator action or electrical power, the A3H1 is remarkably safe when shutdown. This also means that the reactor plant can perform a battery-only start-up, which is highly valuable for combat scenarios or a loss of all reactor plants simultaneously.

Radiation shielding is required and makes up the outside of the reactor compartment, which houses the reactor, boiler units, coolant loops, reactor coolant pumps, pressurizer, and filtration system. The shielding is made up of borated poly, water tanks, steel, and lead. It also has photovoltaic cells lining the inner wall to provide a trickle-flow of electricity to power the ship's battery and auxiliary reactor-plant batteries. With the reactor at power this trickle flow can be used to maintain supply of electricity to critical components. Entering this reactor compartment while the reactor is at power is considered to be deadly, but the layered shielding is so sufficient that personnel working in the propulsion plant will receive less radiation than those working on the weatherdecks of the vessel.

In the event of a loss of power, several emergency diesel generators can provide auxiliary power. This are primarily designed to support the reactor plant's automatic fill protection system, but they can also be aligned to the common electrical distribution system for propulsion power.


Amenities:
Crew amenities, for the most part, are as standard with any Pharthan Navy ship. Each individual sailor is allotted their own "Coffin-Rack," which storage underneath the rack, which sits in a tray that can be lifted to expose personal storage space, as well as a personal locker. Each rack space comes with a personal reading light, towel-hangar, emergency egress breathing device stowage, personal six-outlet power strip, and a state-of-the-art Smart Reveille Suite, or SRS.
The SRS monitors the sleep pattern of the sailor, and can be programmed in with the applicable Watchstation Schedule, Morning Routine & Muster, et cetera. For those requiring certain amounts of sleep such as pilots, it can also advise the sailor on when they should be falling sleep. The SRS is a built in computer roughly the size of a smart-phone, built into the rack itself and is tamper resistant. It also includes vibration sensors which are, as a standard, built into the walls and base of the rack, as well as separate remote sensors to be able to differentiate natural ship motion from the motions of the sailor.
To promote healthy sleep, the SRS will begin playing soft music of the sailor's choice to ease them awake within the optimal period prior to their next appointment, as well as emitting "peaceful" light.
In the event the sailor is late for watch or muster, a louder alarm and brighter lights will be emitted.
The speakers for the sounds are directed inward, and additional sound-proofing is provided to prevent disturbing other sailors.

While differing on each ship and in each compartment slightly, each berthing location houses between eight and 12 enlisted sailors. Officer berthings may be singular, double, or a quartet, depending on rank and station. Each berthing space comes with one computer, which, when available, is linked to the ship's internet and unclassified network; internet browsing on this network is often limited for security reasons, though general social media is allowed. A separate web-browser notebook is also provided to allow sailors to download movies, games, videos, et cetera, and more extensive chat with family. While still monitored for security reasons, this is not connected to the ship's unclassified data network and is more free to use.
Each berthing space has an ample amount of electrical outlets and storage space, both communal and personal, to allow for personal gaming systems, and each berthing space has one large flatscreen TV, with space for an extra. Additionally, every berthing space has their own minifridge and microwave oven.
For every forty sailors there is an additional community space, allowing for more activities to include the watching of movies, TV, gaming, et cetera, without disturbing those sleeping at the time.

For every sixteen sailors there is at least one head, to include two showers, two toilet stalls, and three sinks, though some areas may include more based on availability. These are often of stainless steel construction for sanitary reasons, and the shower-stalls are curtained off, though some may include a hard vanity door.

Gym services include rowing machines, various styles of treadmills, weight machines and racks, yoga mats and equipment, sports equipment for any open areas, and more at the request of the ship's recreational officers.

Description
The High Noble-class carrier is an extensive refit to the older Noble-class carrier, which is even a further refit of the older Citadel-class. While still quite similar in outer appearance, the High Noble maintains the fixes and streamlining that the Noble achieved over the Citadel. In addition come even more ventilation and compartmentalization improvements, allowing even some of the smaller sectors of the ship to be easily isolated. The entire ship maintains heating and air conditioning systems suited to maintaining a comfortable living condition in any environment the world has to offer it, as well as better particulate filtering and dehumidifiers.

Coming from the Citadel's success with the six-elevator, six-catapult, two-trap system, the High Noble still uses a centerline island, but advances in automation, electronics, and sensors allow for the island to be smaller, to allow for more flight-deck space without sacrificing necessary bridge space. The windows on the island also allow for old-school visuals of the flight deck in addition to the many cameras. The added two elevators are necessary in assisting in moving aircraft about the flight deck during Flight-Operations (FLOPS), taking into consideration the ability to land twice as many aircraft as a typical carrier while also launching the same volume as it's predecessors. These covered elevators also provide an added degree of protection from both enemy munitions and prying eyes, allowing for normal flight-deck preparations to be performed relatively outdoors and rapidly launching the aircraft from a safe location, in the event of war, high-seas, or a black-operation.

In addition, each of the external elevators sports a crane which can reach as far out as ninety-five-feet from the edges of the boat, an improvement over the 70 feet from the Noble, and as far in as near the center-line of the carrier, where cargo can be rapidly transported by internal ceiling-bound cranes or mobile cranes. While not ideal, these cranes can be used for resupply-at-sea. The crane's support arms are embedded beneath the flight-deck, fixing it in place. In the event of a failure of the primary and secondary hydraulic locomotive drives of the elevators, the crane can act as a tertiary lift, albeit slow. Unlike the Citadel, this crane is far better protected and it's support more internal.

The High Noble sports a larger flight deck over the Noble, allowing for easier movement of aircraft around the flight deck and the ability to hold a six more aircraft, ideally. The smaller island footprint also allows for management of larger aircraft, and the extended bow end of the flight deck allows forty-foot longer catapults. Another notable hull improvement is a slightly reshaped bow designed to help prevent the tumblehome from knifing too far into the water and preventing waves from crashing over the flight-deck.

The rearrangement of point defense systems leaves the High Noble much more suited to defense than the Noble, with reduced numbers of 30mm CIWS, but five new 57mm CIWS and more missile defense systems; this allows the carrier to engage targets further out than previous iterations.

Most importantly - and most expensively - changed from the Noble, is the entire electronics and sensory refit; all computers are newer technology, server units newer, and software significantly upgraded. Externally visible, communications units have been upgraded as well as sensors. A considerably higher mounted, multi-point primary-air search radar unit allows for higher accuracy and precision in long-range detection and tracking down stealthier aircraft.

Supplementing the primary-air search is a ballistic-missile defense radar mounted forward of the main radar mast.

The propulsion system itself is the largest advancement over the Citadel; the addition of a new azipod aft - meaning that the two most centerline azipods do not maintain a full range of motion - as well as using the same engines for six internal engines, allowing for speeds that would normally be considered ridiculous for carriers so large.

Theia Prime
Author: Marquesan


Overview:
Theia Prime is the name given to an extremely powerful optical targeting suite fielded on large warships in a single, stabilized and isolated turret. The system incorporates an extremely high resolution still and video camera with a very large telephoto lens, a Coherent Doppler/LIDAR (CDL) array, a Continuous-Wave Infrared Camera and a set of three laser rangefinders. The armored turret in which Theia Prime sits is a low-RCS design which is triple vibration isolated and stabilized with super fine adjustable electric motors. The entire turret is a sealed design, cryogenically-cooled with anti-glare lenses for extreme image purity and outstanding low-light/zero lux performance. Theia Prime is designed to provide crystal-clear situational awareness in sensor fusion from a multitude of different sources with an unprecedented level of data coherence and resolution. Theia Prime seamlessly integrates identification, targeting and fire control on an ultra-fine level, precisely accounting for all possible variables and bringing to bear a wide network of sensors to completely account for surveillance of the battlespace and also for present threats to the vessel.

Theia Prime Turret:
The turret moves as a unified structure with the primary gimbal, which utilizes direct-drive brushless torque motors with rare-earth magnets and high accuracy angular transducers coupled directly to precision shafts for accurate and smooth 360° continuous motion. The absence of gear trains and other drive mechanisms eliminates position error contributions due to mechanical hysteresis and backlash. Directly-coupled high-resolution position transducers ensure highly accurate and repeatable positioning. A built-in azimuth slip ring provides for continuous rotation. To maximize positioning and velocity performance, high torque brushless, slotless servomotors are utilized throughout the entire assembly. These motors have all of the advantages of a brushless direct-drive motor — no brushes to wear, no gear trains to maintain and high acceleration and high speeds. Since it is a slotless, ironless design, there is zero cogging, meaning that there is absolutely no torque ripple. This results in smoother motion throughout travel and more precise positioning. Large diameter, matched-set ceramic ball bearings maximize performance with respect to wobble, moment stiffness and rotating friction. The ceramic ball bearings are held to ABEC-9 standards, and are much harder than steel balls (over 100% harder). This, combined with their excellent surface finish is the reason they dramatically out-wear steel types. In identical running conditions, the balls in ceramic bearings exhibit less than 10% of the wear of steel balls and have a considerably finer surface finish. The large diameter bearing permits large payload capacity without compromising performance. Casting gimbal yokes provide high stiffness to maintain gimbal accuracy under dynamic conditions.

Sensor Suite:
Theia Prime is built around its primary optical sensor, an array of 220 CMOS sensors arranged around a central focusing lens. This "gigagon" array uses the CMOSIS CHR70M, a 35mm optical sensor which operates at 10,000 by 7,096 pixels, or 70 megapixels, at a frame rate of 3 FPS. Together, the combined power of the camera is a whopping 15.4 gigapixels, the most powerful single camera ever built. At full resolution, three full-sized stills can be taken per second, or the camera can be fired at intervals giving higher framerates at lower ultimate resolution for high speed tracking, up to 70 megapixels at 660 FPS, with variable frame rates and image qualities selectable dependent on mission parameters. The focusing lens is fitted to a fully automatic SLR Telephoto lens designed specifically for Theia Prime. The massive lens uses direct drive stepping motors to adjust its focus and is fully encapsulated in the Theia Prime turret. The zoom focus of the lens is designed to focus on objects between 29 and 52 kilometers away using a Catadioptric system, but with the extremely powerful camera behind it, can resolve extreme detail at much greater distances, with facial recognition possible as far as 120 kilometers. The focal length of the massive lens is 5,150mm with a minimum object distance of 120 meters. Exposure control is accomplished with the use of built-in ND filters, corresponding to f/14, f/16, f/22 and f/32. The SLR lens itself is 500mm in width and 600mm in height and a massive 1,890mm in length. Spherical main and secondary mirrors are ultra-smooth gold-coated beryllium and all lenses are finely ground and polished magnesium fluoride-coated sapphire. The entire assembly is krypton/argon filled and exhibits truly world-class zero-distortion performance, even in zero lux conditions.

The data from the Theia Prime camera feeds the ship's central fire control and targeting systems, and is referenced to an 8-Megapixel ultraviolet camera shooting in the 190nm to 400nm range and an extremely long range 1080p continuous wave infrared camera in the 300/2,000mm format with zoom laser diodes. Integrated fire control is provided by a highly advanced 1.5 micron Coherent Doppler/LIDAR array. CDL uses dual summed beams operating spaced apart and at different frequencies to take extremely precise measurements of windspeed, particulate matter and other atmospheric variables between the vessel and the target. Paired to each CDL is a set of three 80mJ Laser Rangefinders, operating at 20 pulses per second at the 635nm wavelength. Each beam has less than .3 mrad divergence and the paired system is used to positively locate and track a target, even one moving at incredibly high speeds so that weapons may be brought to bear to counter the threat.

Illumination Turret:
An identical armored low-RCS turret to the sensor suite contains an extremely powerful spotlight which can be synchronized to the sensor turret or operated separately. Visible as far as 210 km away and capable of illuminating aircraft at cruising altitudes in the upper atmosphere, the stabilized, fast-moving xenon short-arc lamp is among the most powerful battlefield lights ever produced. A 50-kilowatt xenon lamp is at the heart of Theia Prime's illumination turret, housed in a graphite housing with carbon/carbon stays reinforced with boron carbide ceramic to handle the extreme heat produced by the massive lamp. The lamp itself is cooled with Fluorinert dielectric fluid and uses ultra smooth gold-coated beryllium parabolic cold mirrors to focus a finely-collimated beam of pure white light through a spinel nanoceramic transparent armor emitter. These lamps produce a tight focus even out to maximum ranges and are extremely useful for battlefield illumination. A switchable infrared filter is contained inside the lamp assembly; a motorized cylinder drives a specially-coated glass cylinder which encapsulates the entire bulb and allows only IR light from the bulb to penetrate the tube, making the powerful light invisible to the naked eye. This allows an extremely powerful IR beam to be shot out to a distance of 70 km, a useful and deadly application for combat operations.

Why haven't I had anything new in my storefront for so long? This is why. I've been busy.
