Overview
With a period of great expansion and improved traning in full swing, DPUO's Navy and its' staff felt that they had a right to feel content with themselves. The Navy was large, with more than 100 capital ships alone, and amply powerful. It was a capable force, able to carry out operations under any conditions and against any opponent; it was also hideously costly to maintain and use. The construction of Naval bases and the procurement of Naval vessels had been a gigantic strain on the economy, and the recovery from this strain was still in progress when a spate of harsh anti-Left Wing measures began to ripple across the world, instigated by Far Right wing states. The power of the Navy to decide the outcome of such events was realised by Parliament (indeed it was, as always, one of the primary arguments behind its' expansion), and thus it was often the first force to be sent to do its' duty against the enemy.
During the many small and large punitive operations that this work entailed, there emerged a clear problem.At most of the Naval bases that DPUO possessed globally, there was a strong capital ship presence, comprising usually battlecruisers and escort carriers and helicopter & V/STOL carriers. However, it was necessary to keep these forces in close proximity in order for their (theoretically) high degree of combat power to be put to good use. The fact that the battlecruisers were often swifter and longer-ranged than the carriers (many of which were ageing) did not make this task easy; the difficulty was enhanced by the knowledge among the carrier crews that the battlecruisers were in general far better armed than they were, which encouraged carrier crews to endorse the view that they should proceed behind the capital ships, which often had the unhappy result that the battlecruisers left behind their air cover as it went back to refuel. Although no ships were lost to this and similar incidents, it was seen by the Naval Staff that there was a very real risk of heavy capital ship losses if the situation was not corrected.
The matter was considered at length by the Naval Staff. The need was for a warship that combined the features of Battleship and aircraft carrier. Previous attempts had been notable by their lack of success, from Ise and Hyuga to Moskva and Kiev, the theoretical brilliance of the concept and design had never quite translated into a practical weapon of war. Undeterred, the Naval Office began in earnest studies into a design for a hybrid battleship-carrier. The designs were based on those of the Ise and Hyuga following their conversion to battleship-carriers in 1943, since this was felt to be the closest precendent. After 15 months of hard work and 21 design alterations and revisions, the design was considered ready, and the newly-completed Admiralty Shipyards were assigned the task of building these mighty vessels.
General
Displacement: 82,700 tonnes light, 106,800 tonnes full load
Dimensions:
Length 249m
Beam (at widest point): 49.5m
Draught (mean): 11.4m
Complement: 1,700, air wing 490.
Endurance: 190 days' combat operations, 230 days' steaming.
Armament
The Repulse carries the DK-17 16-inch 45-calibre rifled Naval gun, as fitted to the Soyuz-class battleship, mounted in two twin-gun turrets.. The guns have a maximum accurate range of approximately 24 kilometres and maximum range of 40 kilometres, and can fire APDS, HE-FRAG, HE and low-calibre (10-inch) guided shells, as well as a rocket-assisted shells with a range of 57 km, but an accurate range of 28Km. Barrel life is estimated at 350 full-charge firings per gun. The guns can elavate to 40 degrees and depress to -10 degrees.
Secondary armament is the DK-80 8-inch 34-calibre gun, housed in two twin-gun turrets on the beam. The guns can elevate to 37 degrees and depress to -9 degrees, and have a range of 38km, firing APFSDS, APHE, HE and HE-FRANG shells.
Anti-aircraft defences are based on a three-tiered system, which centres around the new ASP-101 3-D Air Search radar. ASP-101 comprises a powerful array of four fixed emitters mounted high on the ship, a new targeting and interrogation computer system, and datalinking to the radars and sensors of other platforms. ASP-101 is designed to collate all available information and use this information as rapidly as possible to elminate threats to the ship and its' group. The ASP-101 emitters have a range of approximately 350 miles, and can detect and track sea-skimming targets in bad weather at ranges of up to 100 miles. The system uses a powerful targeting algorithm to assign priorities of destruction to incoming targets and to detect even stealthy targets.
The SA-N-6 provides long-range AA and anti-missile defence for the Repulse-class. Its' fire-control radar systems are fully integrated into the ASP-101 system but can be separated from it at any time if necessary. Mid-range air defences are provided by the SA-N-9 SAM, which is controlled by the same method as SA-N-6. Short-range air defence is based around the SA-N-20 SAM, which operates independently of the ASP-101 system unless it is manually integrated with the latter. The SA-N-20 is able to track and destroy sea-kimming missiles moving at upwards of Mach 2 in all weathers. The final line of air defences is 8 AO-18 CIWS units. These are capable of autonomous operation using inbuilt radar and LADAR suites, but can also be guided by the ASP-101 or other datalinked radars and detection systems.
ASW defence is undertaken by two SS-N-27 ASROC launchers mounted at the corners of the superstructure. The SS-N-27 is a ballistic rocket-booster carrying the Type 40 torpedo. The Type 40 has a range of 16Km and an acquisition range in ping-and-listen mode of 4,000m.
The ship also carries 28 SS-N-19B anti-ship/land attack missiles. The missile flies approximately 20m above sea level at 1,900 knots, and can employ active radar or anti-radiation guidance; it has a range of 660Km.
Air Operations
There are two angled runways, each with one steam catapult. The runways are each 159m long. Total area for air operations is approximately 6,000m2.
Air Wing
The Repulse can carry an air wing of 58 aircraft and 10 UAVs. The standard air unit aboard is:
28 Su-33B strike fighters
12 Yak-41M2 interceptors
14 Ka-27B ASW/utility helicopters
4 Ka-31 electronic warfare helicopters
10 Yak-061 "Shmel" UAVs
This combination can be varied with ease. The ship can also accommodate the Su-39B straike aircraft and the Mi-24VU attack helicopter.
Compartmentation
The hull is divided into 11 watertight compartments by 125mm titanium alloy bulkheads.
1) Forward accommodation, bow LF sonar dome, batteries, galleys, recreation area, storage;
2) A turret magazine, A turret CIWS magazine;
3) B turret magazine, forward CIWS magazine;
4) Secondary armament magazine, SA-N-9 magazine;
5) SS-N-19 cells, SA-N-6 cells;
6) Reactor spaces, after CIWS magazines, after SA-N-20 magazines;
7) Aviation fuel storage, emergency diesel engines for shafts 1 and 4;
8) Machinery spaces (heat exchangers and turbines);
9) Aviation fuel storage, emergency engines for shafts 2 and 3;
10) Auxiliary machinery spaces (turboalternators, batteries), aviation fuel storage;
11) Stern accommodation, aviation fuel storage.
N.B. Aviation fuel and ammunition are stored above each compartment aft of compartment 5. Those compartments marked as storing "aviation fuel" have aviation fuel within them, below the upper compartment roof, as well as above it.
