The LARGEST subs ever built, these HUGE twin hulled "boomers" really caught lots of interest after Tom Clancy's HUNT FOR RED OCTOBER became a best seller. Only 1, Dmitri Donski, survives in a operational state, as a test bed for new ICBMs. DFO

The Project 941 or Akula (Russian: Акула, lit. 'Shark') class submarine (NATO reporting name: Typhoon) is a type of nuclear-powered ballistic missile submarine deployed by the Soviet Navy in the 1980s. With a submerged displacement of 48,000 tonnes, the Typhoons are the largest submarines ever built,[3] able to accommodate comfortable living facilities for the crew when submerged for months on end. The source of the NATO reporting name remains unclear, although it is often claimed to be related to the use of the word "typhoon" by General Secretary Leonid Brezhnev of the Communist Party in a 1974 speech while describing a new type of nuclear ballistic missile submarine, as a reaction to the United States Navy's new Ohio-class submarine.

The Russian Navy cancelled its Typhoon modernisation program in March 2012, stating that modernising one Typhoon would be as expensive as building two new Borei-class submarines. With the announcement that Russia has eliminated the last SS-N-20 Sturgeon SLBMs in September 2012, the remaining Typhoons have reached the end of service.

Besides their missile armament, the Typhoon class features six torpedo tubes; all of which are designed to handle RPK-2 (SS-N-15) missiles or Type 53 torpedoes. A Typhoon-class submarine can stay submerged for periods up to 120 days[1] in normal conditions, and potentially more if deemed necessary (e.g., in the case of a nuclear war). Their primary weapons system is composed of 20 R-39 (NATO: SS-N-20) ballistic missiles (SLBM) with a maximum of 10 MIRV nuclear warheads each. Technically, Typhoons were able to deploy their long-range nuclear missiles while moored at their docks.[8]

Typhoon-class submarines feature multiple pressure hulls, similar to the World War II Japanese I-400-class submarine, that simplifies internal design while making the vessel much wider than a normal submarine. In the main body of the sub, two long pressure hulls lie parallel with a third, smaller pressure hull above them (which protrudes just below the sail), and two other pressure hulls for torpedoes and steering gear. This also greatly increases their survivability — even if one pressure hull is breached, the crew members in the other are safe and there is less potential for flooding.

The Typhoon is capable of traveling at 28 kn (52 km/h; 32 mph) underwater.[9]
