Arrow class Battlecruiser
http://img51.exs.cx/img51/9219/BCN3-1mutantmodfin.jpg
Overview
Battlecruiser design and development fell largely into abeyance following the succesful commencement of the two previous classes, the Tempest and Admiral-class BCNs. These vessels were after all well-suited for their roles and in any case the national shipyards were working overtime to complete the ships ordered.
However, several factors now came together which resulted in the need for new warships. The first was the development of the new generation of electronics for shipboard applications of all types. These included fire-control systems, radars, ESM units and so forth. The second was the increasing emphasis on Naval power projection with major surface combatants, for use mainly against Communist Mississippi. The third was the deployment of the KKK cruisers, which, although inferior in all respects to the two prior classes, were nonetheless a possible threat. Contracting was offered to all the major design bureaux, but eventually only the Soyuz DB remained, this being the largest DPUO Naval construction yard and thus best able to build still more new ships.
Development was initianted within 5 days of learning the specification of the KKK by the Soyuz Design Bureau. The designs submitted were of various types, but all armed with 15in guns to allow commonality of ammunition with the Admiral-class BCN.
The design shares many common components with the Admirals, including reactor plants, turbines, backup engines, batteries, primary and secondary gun turrets, and armour systems.
General
Crew: 1,605
Displacement: 64,545 tonnes unladen, 76,982 tonnes fully laden
Endurance: 110 days' steaming, 65 days' combat
Dimensions: Length 381m, Beam 30.69m, Draught 8.9m (mean)
Armament
Main armament is the DK-77 15-inch rifled naval gun, mounted in four twin-gun turrets each 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 450 full-charge firings.
Secondary armament is eight 2A64N1 lengthened smoothbore 152mm guns, mounted in triple turrets toward the stern of the ship. The guns can elavate to 46 degrees, depress to -16 degrees, and have a maximum range of 33km and a maximum accurate range of 20km. The guns can as in the Tempest fire the Krasnopol-M ATGM.
The ship also carries 45 VLS cells for the SS-N-19 or -19B long-range cruise missile, and a pair of new, seven-round VLS cells for the SS-N-26 "Yakhont" SSM atop the superstructure, fed by armoured vertical reloading system chutes. The VLS is currently still in its' early stages, although testing using compressed gas launching has been succesful.
The SS-N-19B is the product of a lengthy development programme to upgrade the SS-N-19 AShM. The upgrade package includes a more compact, slightly lengthened (by 200mm) booster motor using modified solid-fuel propellant, a new radar system with extended range and built-in ECCM and frequency-hopping abilities, and armour as fitted to the Yakhont AShM on the nose of the missile. The missile can now in fact approach sea-skimming altitudes, no more than 15-20m above the waves. Work continues on producing a sea-skimming SS-N-19U.
Anti-aircraft and anti-missile defences consist of 7 AO-18 CIWS guns and 4 ASL-100 combination gun-flechette launchers. The latter form the IULLDES (http://forums2.jolt.co.uk/showthread.php?t=343036) defence system, which is responsible for short and very short-range anti-aircraft and anti-missile defences. Mid-range defence is the SA-N-9 SAM, set in four launchers mounted on the superstructure and fed by armoured vertical reloading chutes. Long-range air defences are provided by the SA-N-6 SAM, mounted on either side of the after deck in two 7-cell VLS units.
Anti-submarine systems consist of the SS-N-27 ballistic anti-sub weapon launcher, of which three are carried, one astern and one on the bows in rounded, armoured housings, and four FRAS-1 anti-submarine mortars, mounted to give maximum coverage of the ship's sides. These mortars must be reloaded by a rotary autoloader after a full discharge, which requires approximately 5 minutes.
The ship carries a towed anti-torpedo decoy, type DT-101.
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 belowdecks on the sternquarter, and the helipad doubles as the hydraulic aircraft lift to allow the aircraft/drones to lift off.
Ammunition allocations
Main armament: 880 rounds
Secondary armament: 720 rounds
SA-N-6: 100 missiles
SA-N-9: 120 missiles
SA-N-20: 60 missiles
SS-N-19: 35 missiles
SS-N-26: 28 missiles
SS-N-27: 18 missiles
FRAS-1: 320 rockets
CIWS: 233,000 rounds
Compartmentation
The hull is divided by 90mm titanium alloy bulkheads into 13 compartments, each with its' own independent pump system and power generator for that pump system.
1) Storage, crew accommodation, fuel for emergency gas turbine engines, sonar dome, sonar backup computers;
2) Storage, crew accommodation, backup fire-control systems, 10% A turret ammunition storage;
3) Forward main armament and main CIWS storage;
4) Secondary multiple armament storage magazines;
5) Emergency belowdeck control compartment, feed system for SS-N-26 VLS;
6) Reactor spaces, bisected longitudinally by 150mm titanium alloy bulkhead;
7) Secondary turrets A and B ammunitions storage, CIWS storage, emergency diesel engines;
8) Main machinery spaces, containing heat exchangers, steam turbines and gearing for turbines;
9) Emergency generators, SAM storage, VLS cells for SS-N-19B;
10) Turret X ammunition storage;
11) Turret Y ammunition storage;
12) Hangar bay and aircraft weapons magazines;
13) Stern accommodation, stern SS-N-27 magazine, helipad/lift apparatus.
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.
Armour
The armour belt runs thusly:
Bow to bulkhead 2: 360mm composite armour with double-layer of Kontakt-5 ERA. Deck armour of two layers of 120mm composite armour, with insulating foam in between layers.
Bulkhead 2 to bulkhead 5: 400mm composite armour, with double-layer of Kontakt-5 ERA. Deck armour of two layers of 180mm composite armour, with insulating foam between layers. 150mm torpedo bulge.
Bulkhead 5 to bulkhead 7: 330mm composite armour, with double-layer of Kontakt-5 ERA. Deck armour of two layers of 195mm composite armour, with insulating foam between layers. 100mm torpedo bulge, widening to 150mm at bulkhead 2.

Bulkhead 4 to bulkhead 9: 330mm composite armour, with double-layer of Kontakt-5 ERA. Deck armour of two layers of 180mm composite armour, with insulating foam between layers. 150mm torpedo bulge.
Bulkhead 9 to bulkhead 11: 385mm composite armour with double-layer of Kontakt-5 ERA. Deck armour of two layers of 120mm composite armour, with insulating foam in between layers. Torpedo bulge narrows from 150mm at bulkhead 9 to 0mm at bulkhead 11.

EW
ESM receiver Type 667 and Type 889, similar to Bell Shroud;
Bell Squat Jammer systems
Burn Eye anti-LADAR smoke generators; armoured vents in sides of hull
22 PK-10 Chaff Decoy RLs
Propulsion
2 OK-700V 210MW Pressurised-water reactors driving four sets geared steam turbines turning four shafts, each with 1 seven-bladed variable-pitch bronze screw.
4 backup S-66M 10,000hp diesel engines, one per shaft, driving through two automatic gearboxes with 4 forward and 2 reverse speeds, slaved via 1 direct-drive shaft per engine to 1 B-12 emergency generator.
Top speed for the class is 38-39 knots.
As per usual, feedback is welcomed.
Incidentally, I don't know enough about AShMs to say whether getting an N-19 to do that is possible, so feedback on that much appreciated.
