Anubis-class guided missile Battlecruiser (BCGN)
http://img94.exs.cx/img94/1733/AnubisClass1.jpg
Overview
The Anubis class heavy guided missile cruiser was the product of a joint development project between DPUO and Sethesh, initiated with the aim of providing a in improved long-range strike capability against large surface forces as compared with previous designs for the Navies of both nations. Development was undertaken by the Admiralty of DPUO and the Office of Sethesh Naval Forces. Production of these vessels is mainly taking place in Sethesh, since DPUO’s shipyards are currently working on production of Repulse-class battlecarriers for export customers.
General
Crew: 1,605
Displacement: 59,931 tonnes unladen, 66,482 tonnes fully laden
Endurance: 110 days' steaming, 65 days' combat
Dimensions: Length 311m, Beam 30.69m, Draught 11.9m (mean)
Armament
The main armament of this class is not the battlecruiser’s traditional gun armament, but the combined armament of 80 SS-N-19B anti-ship missiles and 142 SS-N-22 Sunburn anti-ship missiles. These are guided by shipboard radar systems, with OTH targeting provided by helicopters or UAVs where recent and/or accurate information from other surveillance systems on the location of the target is unavailable.
SS-N-19B Shipwreck-B/P700M is an upgraded variant of the P700 missile, primarily in terms of missile guidance and control. The P700M missile carries, in addition to the single K-band terminal guidance radar carried by the P700, two millimetric-wave X-band radar units above and beneath the X-band radar emitter. The missile also carries a pair of LADAR units, faired into the sides of the missile’s nosecone during flight, and a pair of IRST sensors, faired into the top and bottom of the nosecone.
During approach flight, the sensors remain inactive and within the nosecone. When the missile closes to within the specified range of the target, the sensors are activated, and the four fairings emerge from the nosecone to allow them to acquire the target. This system greatly increases the missile’s resistance to jamming and lures.
The missile is also provided with an uprated ramjet engine and improved guidance computer, allowing it to fly at altitudes as low as 17m above the ocean. This allows P700M to operate in a similar manner to the 3M82 missile, flying high and relatively slow to the target before dropping down to sea-level to evade radar detection and accelerating toward the defending ship, allowing it much less chance to destroy the missile. The P700M carries a 750Kg HE warhead, an FAE warhead, or a 300Kt nuclear warhead.
The 3M82 Moskit /SS-N-22 Sunburn is a well-known missile system designed to provide a mid-range anti-ship capability for destroyers. The 3M82 Moskit missiles have the fastest flying speed among all anti-ship missiles in today's world. It reaches Mach 3 at a high altitude and its maximum low-altitude speed is M2.2, triple the speed of the American Harpoon. It has a range of 150 kilometres and a sea-skimming terminal flight path, carrying a 320 kilogram warhead.
The missiles carried are supplemented by the ship’s main gun armament of three DK-77 15-inch rifled naval guns, mounted in a single triple-gun turret forward, with elevation of 44 degrees and depression of -13 degrees. The guns fire APDS, HE, HE-FRAG, smoke, laser-guided 8-inch and chemical shells. Maximum range is 43km, with an accurate range of 22.8km. The armour-piercing shell has a mass of 2,022lbs. Barrel life is approximately 1,150 full-charge firings of the gun.
The ship’s secondary gun armament is the 2A64N1 lengthened smoothbore 152mm gun, mounted in two triple turrets at the stern of the ship’s superstructure. The guns can elevate to 46 degrees, depress to -16 degrees, and have a maximum range of 33km and a maximum accurate range of 20km. The guns can fire the Krasnopol-M ATGM.
Anti-aircraft defence is a three-tiered system. First is the SA-N-6 (S-300PMU) long-range SAM, capable of use against aircraft and sea-skimming missiles and with a maximum range of 30km, which is mounted in 28 reloadable VLS cells. Next layer of defence is the mid-range SA-N-9 (9K331 Tor) SAM, for which there are three launchers. The missile has a maximum range of 12km and is capable of engaging sea-skimming missiles and aircraft. The final defence layer on the ship against missile attack is 11 AO-18 CIWS units, which are mounted on various points on the superstructure.
Anti-submarine defence is provided by the ship’s helicopter/s, and is augmented by 6 RBU-6000 anti-submarine mortar launchers, carried in pairs, one forward, one amidships and one aft.
The vessel also carries a DT-101 towed acoustic anti-torpedo decoy.
This class also has a hangar bay that can accommodate 2 Ka-27B ASW helicopters or eight Yak-061 "Shmel" UAVs. The hangar is placed on the aft superstructure.
Ammunition allocations
Main armament: 330 rounds
Secondary armament: 396 rounds
SA-N-6: 140 missiles
SA-N-9: 120 missiles
SS-N-19: 80 missiles
SS-N-22: 142 missiles
RBU-6000: 144 mortars
CIWS: 240,000 rounds
Compartments
The hull is divided by 290mm titanium alloy bulkheads into 13 compartments, each with its' own independent pump system and batteries for that pump system.
1) Storage, crew accommodation, fuel for emergency diesel engines, sonar dome, sonar backup computers, galleys;
2) Storage, crew accommodation, backup fire-control systems, Sunburn cell block, forward AO-18 and RBU-6000 magazines;
3) Forward SS-N-19 launch cell block;
4) Main gun magazine, forward SAM magazines and CIWS magazine;
5) Forward main missile battery;
6) Reactor spaces, bisected longitudinally by 150mm titanium alloy bulkhead, midships battery 1;
7) Midships battery B, main machinery spaces, missile magazines for SA-N-6 missiles, emergency diesel engines;
8) After Grumble and Gauntlet magazines;
9) After turret magazine A, aircraft munitions magazine;
10) After gun magazine B;
11) After Sunburn launch tubes;
12) After Sunburn tubes block B, steering gear;
13) Stern accommodation, stern RBU-6000 and SA-N-9 magazine, VDS spools..
The ammunition magazines incorporate blow-out panels and pressure-release valves to minimise damage in the event of a magazine explosion. The large open spaces of the engine and reactor rooms are divided by transverse bulkheads separating the individual reactors, engines and shafts. One reactor can run both sets of turbines via pipelines which traverse the bulkheads. The movement of the turboalternators and backup engines to separate compartments reduces the chance of a single hit disabling the ship's power.
