The Waarden-class is a class of air defence cruisers in service with both the Commonwealth Navy of Yohannes and Marine of the Knootian Defence Force, as well as the navies of over 100 nations around the world. Originally envisaged by the Union of Knootian Shipbuilders as an advanced area-defence platform, the class is possibly the most advanced warship jointly-constructed by the Union of Knootian and the Freethinkers Shipbuilders, extensively refitted by Royal Beaufort Shipwrights Guild. She was originally envisaged as a heavy destroyer, but was redesigned as a cruiser when the new concept of Naval Battle Groups was approved by the Marine. Two ships of its class sail with every battle group, complementing the air defences of individual ships.
Originating in the ‘X104 Programme’ initiated in the first term of His Majesty’s 92nd Parliament, the Waarden was envisioned as a fast, small task force leading pseudo-capital ship to enforce Yohannesian commerce and trade abroad. As the project progressed, however, the ship increased in size to nearly 220 metres and more than 20,000 tonnes, resulting in a much higher cost than expected and leading to an almost complete revamping of the project to fulfil that of an area aerial defence and simultaneous capital ship instead. The design was also redesigned entirely to ensure its efficiency, and its comparative edge in fulfilling export market demand.
The first of the redesigned Waarden Class nuclear guided cruiser was launched by the Regent Cid IV at the Royal Lindblum Construction Yard, and upon its launch, was described as “yet another class of essential oceanic multi mission platform to enforce and ensure His Majesty’s commerce and trade abroad.” The Dutch word 'Waarden' refers to values, in the context of ethics, a concept roughly analogous to virtues. The first seven ships of the class have been named after the seven heavenly virtues. More recent vessels have been named after philosophers and theologians. Prominent ships of the class are the KDF Prudentia, KDF Iustitia, KDF Temperantia, KDF Fortitudo, KDF Fides, KDF Spes, KDF Caritas, KDF Socrates and KDF Machiavelli.
The Waarden Class complements the Phlegethon Class nicely.
Concept
The Waarden class features an entirely new hull design, with enhanced stealth, and features intended to deceive any opponent's radar and acoustic sensors. Four single phased array radars automatically detect and track air contacts, while a long-range 3D radar system is capable of detecting even stealth aircraft and missiles. The phased array panels and the 3D search system are both capable of compensating for each other in the event of damage or failure. A low emission navigation radar is also included.
The fire control system combines all incoming data to provide both range of detection and accurate targeting. The system can control friendly aircraft as well as providing simultaneous surveillance, target-detection and target-tracking in a hemisphere over and around the ship. Secure CAESAR data-links allow the class to utilise the sensors and weapons of other escorts to further increase its effective combat radius. This is especially apparent when multiple Waarden class vessels are linked, rending hundreds of square miles of ocean and neighbouring coastal areas into no-go areas for enemy air operations.
The combat systems of the Waarden class provide the class with the ability to project a protective 'bubble' around whatever area they’re working in, detecting and shooting down hostile aircraft or missiles. Its mass of VLS launchers are designed primarily to deal with saturation air and missile attacks, utilising a mass of surface-to-air missiles hardened for heavy ECM environments.
They can be also be loaded with a variety of missiles designed to engage targets above, on and below the surface, primarily used for anti-strategic missile work, but can be deployed against other air and surface targets. For self defence, quad launchers of CVS401 Perseus stealth supersonic cruise missiles, a standard OTO Melara 127mm/64 D/P Gun identical to that used in other RBSG surface combatant vessels, and 8 Bloemfontein Naval Frontline 20mm CIWS - identical in design to its 30mm variants - mounts were installed. A helicopter hangar for two light helicopters and landing pad were also added.
RBSG refitted Warden-class of vessels are powered with four Weilmfontein AR-06D water reactor pressurised nuclear powered engines, each providing up to 40 mW, powering four electric transmission azimuth propeller pods.
Armament
Nelson VLS 12x 64-Cell Full Length
As one of the primary power projection platform of the Commonwealth Navy and Knootian Marine, the Waarden-class of vessels are armed with its twelve Nelson vertical missile launching systems, designed primarily to deal with saturation air and missile attacks, allowing for the storage and launching of a wide spectrum of surface-to-air naval missiles, up to 768 missiles in total capacity per ship - hardened for heavy ECM environments. Nelson VLS is the Yohannesian replacement of the Mk.41. The Nelson systems bestowed upon her an array of inexpensive aerial defensive measure, harmoniously guided with the existing Wilhelm II Networking & Fire Control package, which provides X-band radar surveillance integrated with target tracking and fire control for the guns and missile systems.
The target's estimated location is acquired by the infrared target tracking sensor, amalgamated within its integrated airframe, command guidance receiver, control systems, ordnance algorithms and signal processor, allowing operational missile deployment without the existence of nominal line target calculation. The Nelson's vertical electrical and mechanical launch infrastructure integrate harmoniously with that of the system, thus providing an efficient rapid deployment and operational accumulation of multiple vertical-launched lightweight designated and optionally chosen missiles.
The vertical stack consists of multiple rows. The rows are stacked vertically in the canister, with each missile stored in its respective tube. Deployment is initiated to the top-tier until no operation missiles remain at top, and sequentially to the bottom in an identical arrangement. Operational missiles are ejected out of the canister's open top end upon depletion of the stack. Command and control information are delivered from the existing launching infrastructure from controller located within the canister.
Prior to engagement, identification of potential threats required from navigational data is obtained by the Wilhelm II integrated fire control & sensor systems. The information will then pass through the VLS, and reached the vessels' controlling interface. Instantaneous crucial information which are included would be that of the opposing target's direction, position, presence probability & percentage, and target velocity.
The Nelson design simultaneously provide an ample supply of instant low-cost, light-weight guided missile presence. The integrated link of command guidance and thrust vector can be located upon the tail section, whilst contact fuse and ordnance located by the middle section. As demonstrated during the Ralkovia-Osthia-Incursus War, or more specifically remembered within the Crown Commonwealth Realms as the Gratislavian Invasion of Osthia, an acceptable air defence umbrella was successfully achieved, in a cost-effective, solid kill probability ratio in relation to the multiple launched missile's low cost.
The Waarden-class of vessels are also equipped with eight CVS401 Perseus stealth supersonic cruise missile systems or Harpoon anti-ship missile systems.
Archibald SARH
The Waarden-class has the capacity to hold up to 24 rolling airframe launched missiles, thereby giving her an essential secondary anti-air/ships missile defence capability. A Yohannesian design, the Archibald is a rolling sidemounted airframe-launched guided missile system that may optionally be used by the vessels. Its integrated directional firing control package is designed to provide an efficient target tracking, gun fire contol capabilities against high-speed and manouverable anti-ship missiles. The system, is guided with that of its alternatively chosen anti-missile weapon systems and boresighted upon the RAM.
A significant decrease of shock and vibration loads is achieved by the addition of split sleeve external rib-shaped connectors towards the launcher which are mounted outboad the mount shield. It simultaneously allow the system to acquire good rigidity, which is essential towards its tracking control capacity at the maximum point of azimuth and elevational rate alteration. The launcher guides may control each singular store within its systematic reach. Such is achieved by the application of its pivotal foundation, supported by the pairing addition of 400 volt actuator cables. This allows good flex mechanism, in turn giving a smooth rotational capacity, without the high probability of cable bend happening.
Ultimately, the said combination allows an unlimited elevational cycle, without the off-set of electrical fatigue and wear-tear problems. Initiations individually permits the instantaneous signal of firing movement to be transferred towards the loaded store. As such, a considerable mix of other secondary rounds load may surreptitiously be added; With some of the favourite Yohannesian alternative being that of chaff and decoys, beside the primary RAM rounds. As an added ultimate benefit, the said feature simultaneously allows the Commonwealth Class' CDS (computerised defensive system) the ability to initiate selection without time-offsetting initial interventions by her operators.

Bloemfontein Naval Frontline (07B) CIWS
Eight Bloemfontein Naval Frontline 20mm CIWS, with its rate of fire of 4,500 rounds per minute at an effective range of up to 1.5 km, provide vessels of the Waarden-class with the acceptable short-range defensive measure of last resort against incoming airborne and surface threats, such as helicopters, aircraft, anti-ship missiles and mines.
Weighting ~6,200 kg, Bloemfontein is a Yohannesian anti-ship, close-in weapon defence system, with six rotating cluster Halstenmetall 20/L128 autocannons, each carrying 1,500 rounds as its preferential weapon option within the Commonwealth Navy. The system is divided into three sub-stages; That of detection being the primary, tracking secondary and interception as the tertiary and final stage. The system detect incoming threats within its initial detection stage, with acquired data being passed towards the succeeding tracking stage. The tracking stage will then automatically track the target, and provide the date further towards the final interception stage. The interception stage will then deflect and/or destroy the target by virtue of its electromagnetic beam, thereby neutralising the detected threat.
Bloemfontein utilised an automated fire control system from that of the established VMK AYTRACK and ADS, modified to suit its purpose. It has the capacity to automatically detect, track and counter multiple anti-ship and aerial threat-identified targets from as close to 500 metres' extended close reach of the system, 1,500 effective higher-than-limit and as far as ~5,000 metres at forty-five degrees elevation. The initial, first stage as mentioned above delivers incoming signals towards the tracking stage, allowing the establishment of interception control solution. It utilised the addition of MHT algorithms (multiple hypothesis) and select combination of IPIAF (Integrated Probability of Information Acquisition Filter).

OTO Melara 127mm/64
Five lightweight mounted 127mm, 64 calibre OTO Melara; a dual-purposed gun with relatively greater fire control capacity in comparison to its predecessor, though with a somewhat reduced firing rate capacity of 25 rounds per minute, taken as its acceptable and slight drawback. Its 4 modular automatic feeding drum magazines -with each holding 14 rounds, allows the gun to fire up to four different, immediately selectable ammunition types - at an effective range of 15,000 m, and maximum range of up to 23,000 m, giving the vessel the ability to effectively engage land and large surface targets with heavy artillery fire.
