The Typhoon-II SSBN

Overview

In its' original form, the Typhoon ballistic-missile submarine was the greatest feat or maritime engineering of the 20th century, displacing more than 33,000 tonnes submerged and carrying more than 200 thermonuclear warheads with the ability to strike anywhere on the planet within a matter of minutes, and able to stay at sea for anything up to four months in comfort. A true monument to the ingenuity of Soviet designers and the ability of Soviet armaments manufacture, these submarines were probably the single finest ships of their type built by any side in the Cold War.

However, at this late stage, the Typhoon, even with all the upgrades applied through 20 years by the Soviet and Russian Navies, is becoming outdated. The basic design of the ship is still superb, but too often it is let down by the systems it uses.

Hence, we have decided to upgrade these wondrous machines, to bring them up to scratch fpor the modern era. We present to you:


The Typhoon-II SSBN


General

Crew: 150, 50 officers)
Displacement: 23,200 tonnes surfaced unladen
33,800 tonnes submerged unladen
24,500 tonnes surfaced fully laden
42,000 tonnes submerged fully laden

Endurance: 120 days' crusing, 90 days' combat
Dimensions: Length 172m, Beam 23.3m, Draught 17.5m [Draught increased by 6m)
Maximum Diving Depth: 500m


Armament

The Typhoon-II carries four 650mm torpedo tubes, able to fire all standard Soviet/Russian torpedoes, including:

533mm

SAET-60
SAET-80
USET-60
USET-80
53-65K
53-65M
SET-65
SS-N-27
UGST, etc

650mm

65-73 (nuclear)
65-76 (conventional)
TEST-71ME, etc

Can also carry SS-N-15 Starfish and SS-N-16 Stallion ASWs.

The ship carries 20 SS-N-20U/R-39M1 ICBMs. These have a range of 10,700km, and carry 10 100Kt MIRVs. Guidance is by inertial navigation, gyroscopic course alteration, and where possible GPS/Satnav. The missiles differ from the original SS-N-20/R-39 in having an altered fuel mixture, similar to that in the Trident D-5, and a new casing lining of an ultralight titanium alloy backed by a small airspace filled with argon gas.

The missile can be replaced with the SS-N-30 SLBM, a seaborne variant of the road-mobile SS-27 Topol-M ICBM, if the user specifies. The SS-N-30 is capable of carrying a single 400Kt warhead.

These vessels also carry active and passive anti-torpedo decoys.

Ammunition allocations

Up to 40 torpedoes/torpedo tube-launched missiles, etc
20 SS-N-20U/SS-N-30 ICBMs
26 countermeasures, standard 14 active and 12 passive countermeasures.

Compartmentation

The ships is divided by 125mm titanium alloy bulkheads into 19 watertight compartments, each equipped with an emergency water pump. These runs thusly:

1) Torpedo room, bow cylindrical sonar;
2) Torpedo storage, accommodation, sonar processing systems;
3) Galley, officer's accommodation, leisure area;
4) Missile bay
5) Missile bay
6) Missile bay
7) Missile bay
8) Missile bay
9) Missile bay
10) Missile bay
11) Missile bay access, missile control wiring, accommodation where possible
12) Command and control systems
13) Command and control systems, life-support housing
14) Reactor spaces
15) Reactor spaces
16) Heat exchangers, turbines
17) Turbines, turboalternators
18) Turboalternators, batteries
19) Steering gear, propulsion equipment.


Armour and Survivability

Although not armoured as such, the ship's design emphasises survivability. The vessel is divided into no less than five hulls, consisting of an outer hull, two side-by-side inner pressure hulls, and a separate command module hull in the sail. There is also a two-metres air space between the outer hull and inner hulls.

The outer hull is built of low-magnetic steel, but the inner hulls are constructed of titanium. The command module can detach and float to the surface if necessary and contains life-support systems to support up to 46 men inside for 72 hours.

The ship's propulsion machinery is double-rafted, and isolated to a great extent from the inner hulls. The rafting arrangement comprises three polymer layers in which are sandwiched two layers of insulating foam.


Electronics

Radar

One Snoop Pair surface-search/air-search radar, detection range for destroyer-sized target 60 miles, with new "Shark Tooth" beam-sharpening systems and computers for greater range against small targets and SURTASS systems.


Sonar

MKG-500M Shark Gill B passive-active sonar suite, able to to track 16 targets simultaneously, can track 688(i)-class SSN at 5 knots at 20Km.

Pithon towed array, proven detection range against a 688(i)-class SSN at five knots is 68Km.

IRST

The Typhoon-II carries the MKO-612 Infra-Red Earch and Track system, designed to supplement the sonar suites of the ship by providing IR detection ability. The system is mounted in the bow of the submarine, in a small bulge above the bow cylindrical sonar array.

Propeller wash sensor

The Typhoon-II mounts the experimental MKH-20 propeller wash sensor. An enlarged version of the sensor used by the 65-76 torpedo, the MKH-20 is designed to detect the disturbed water, dead marine organisms and bubbles characteristic of a propeller having moved through an area of water. The sensor is currently capable only of operation below seven knots.

Mobile sensors

The Typhoon-II can carry four MS-101 UUVs, each fitted with miniaturised passive sonar suites, IRST systems, and MAD. The MS-101 has an endurance of approximately 20 minutes, moving at 20 knots.

Fire-control

SSU-43 fire-control for torpedo armament linked with sonar arrays, radar system etc to produce rapid target engagement abilities, obviating need for separate TMA station, although TMA is retained for backup.

EW

Bulava ESM array, detection range approx. 100Km against most surface-search radars.


Propulsion

2 pressurized water reactors, 190 MW each. The reactor compartments can be accessed via large removable panels above compartment 15, reducing reactor replacement/refueling time and cost.

2 steam turbines, 50,000 shp each, driving two shrouded seven-blade propellers.

Top speed for the class is 12-16 knots surfaced and 25-27 submerged.

GJ. We'd like to salvage the design for this sub.... possible?
