Will give 50% discount to any nation willing to do a line-art of the Davidson class.
Introduction
The culmination of seven years' worth of research and development, the Davidson class represents the People's Sovereign Navy's most powerful supercapital ship to date - the pinnacle of Londinian naval engineering. Construction of the first vessel, the LNV Sir Alistair Davidson, began at the Northolt Naval Yards, and, as the design was steadily refined during the construction process, three more vessels were constructed, LNV Azzopardi, LNV Rosenberger, and LNV Doyle.
Quick statistics
Displacement: 11,375,154 tons
Length: 1433 m
Beam: 189 m
Draft: 56 m
Price: 1.3 trillion Londinian denarii
DPR: Given on a nation by nation basis
Accommodations
The Davidson class has accommodations for 7,575 enlisted personnel, 470 officers, 330 technicians, 50 aircrew, and a further 2,000 Naval Commandos. It possesses luxury quarters for senior naval officers, which adjoin the main observation deck. Lesser ranked officers have slightly smaller, though private rooms, and enlisted personnel reside in a public dormitory, sharing rooms with four other individuals. There is both an officers' mess and an enlisted mess, with meal times staggered throughout a twenty-four hour period to ensure efficiency. Davidson-class vessels are also capable of possessing enough food supplies to last thirteen months, storing them in large, temperature-controlled storerooms.
As the Davidson is designed for fairly long tours of duty, the designers attempted to make the vessel as comfortable as possible for those serving on it, having numerous amenities ranging from wireless internet to ping pong courts.
Weaponry
The Davidson possesses eighteen 32 inch guns in six triple turrets; each gun battery is fibre-optically linked to the ship's radar and sensor arrays, in addition to having auxiliary sensors housed in the battery. Two layers of steel, each 1100 mm thick, provide protection for the ships' main guns.
Supplementing these heavy guns, the Davidson also has thirty two 4.5 inch (114 mm) Mark 8 naval guns. The weapon is semi-automatic and therefore needs fewer people than traditional weapons to operate. There are no personnel in the gunhouse, and only a few in the gunbay to load the feed ring, in addition to the magazine crew. The weapon has a rate of fire of about 25 rounds per minute and a range of 22 km.
Anti-missile and anti-air protection for the Davidson is provided by seventy-five Goalkeeper close-in weapons systems and by fifty RIM-116 Rolling Airframe Missile Launchers. Submarine defence is provided mostly by twenty five Mark 32 Surface Vessel Torpedo Tubes distributed around the vessel, though twenty NATO Seagnat countermeasure launchers provided additional defence. Due to an arrangement with the Leafanistani military, the Davidson can also come with forty CLM-01 Common Laser Modules (http://forums.jolt.co.uk/showpost.php?p=13017726&postcount=14).
Furthermore, the Davidson is equipped with seventy two sets of eight-cell autoloading vertical launch missile launchers, thirty-six of which are optimized for the BGM-109 Storm Shadow, the rest designed primarily for the RGM-84 MBDA Aster. Other missiles can be used with minor adjustments to the launchers.
Armour and Protections
Due to the expense of producing just one Davidson-class superdreadnought, protection was a priority of the Ministry of War designers. The hull is covered by a Byzantine system of armour layers, which consist of:
-120 mm carbon decapping layer
-600 mm steel
-100 mm empty chamber
-350 mm steel
-100 mm empty chamber
-200 mm inclined steel
-100 mm aramide layer
-50 mm dyneema
The ships' decks and bulkheads consist of a 900 mm thick layer of HSLA steel. They are both firestopped and electrically grounded (as a countermeasure against EMI and EMP damage, resulting from nuclear blasts and/or the breaking of the sound barrier near a vessel, which could otherwise severely damage the electronic systems on a ship). The conning tower has a similar armour structure to the hull. Further reinforcement is provided by a layer of steel-alloy honeycombing to prevent loss of structural integrity during a torpedo attack.
Carbon dioxide and dihydrogen monoxide fire extinguishers are placed in every compartment, and specialized chemical and electrical fire extinguishers are placed where necessary. Inflatable lifeboats are provided for all personnel on the Davidson, in addition to cold water survival gear. In the event of flooding, 10 cm thick flood bulkheads will seal off flooded compartments within three seconds of detection.
Aircraft complement
Though primarily a combat vessel, the Davidson also has a small complement of aircraft. The ship is capable of carrying twelve VTOL aircraft or helicopters, in addition to six Dassault nEUROn combat UAVs and nine RQ-2 Pioneer recon UAVs.
Powerplant and propulsion
The Davidson is powered by four National Nuclear Energy pebble bed reactors, each with twenty-two years' worth of fuel, giving the ship an essentially limitless range. In the event of a power failure, the ship has two emergency hydroelectric generators, providing enough energy to maintain vital systems and propulsion. Driving the vessel is seven high-capacity propellers, giving the craft a cruising speed of 29 knots. To assist in precision maneuvers, the Davidson has thirty pumpjets.
Sensors
The Davidson uses the Londinian Defence Industries' SCAESA system (Supercapital Active Electronically Scanned Area) as its radar system. Conventional radars, consisting of a rotating transmitter and sensor, have limited power, are vulnerable to enemy jamming and perform only one function - with separate units therefore required for surveillance, tracking and targeting. As an active array, SCAESA uses software to shape and direct its beam allowing several functions to be carried out at once and, through adaptive waveform control, is virtually immune to enemy jamming. Active arrays have both longer range and higher accuracy than conventional radars. The SCAESA uses two planar arrays to provide coverage over only part of the sky; complete coverage is provided by rotating the arrays, essentially similar to the way conventional radar systems operate. Whilst this may seem to be a disadvantage, the SCAESA radar rotates at 30 revolutions per minute, meaning no part of the sky lacks coverage for more than one second on average - the precise time varies as the beams can also be swept back and forth electronically. In addition, the use of a smaller number of arrays allows the system to be much lighter, allowing placement of the arrays at the top of a prominent mast rather than on the side of the superstructure. The range of this system is nine hundred and sixty kilometres; SCAESA is capable of tracking well over two thousand different targets.
Additionally, the Davidson is equipped with an extensive sonar array capable of pinging an area with a radius of sixty kilometres.
Will give 50% discount to any nation willing to do a line-art of the Davidson class.
