The Typhoon class submarine is a type of nuclear-powered ballistic missile submarine deployed by the Soviet Navy in the 1980s. With a maximum displacement of 26,000 tonnes, Typhoons are the largest class of submarine ever built. The NATO reporting name stems from the use of the word "typhoon" (тайфун) by Leonid Brezhnev in a 1974 speech while describing a new type of nuclear ballistic missile submarine.

Description and history

The Typhoon class was developed under Project 941 as the Russian Akula class (Акула), meaning shark. It is sometimes confused with other submarines, as Akula is the name NATO uses to designate the Russian Project 971 Shchuka-B (Щука-Б) class attack submarines.

Typhoon submarines are among the quietest sea vessels in operation, being quieter and yet more maneuverable than their predecessors. Besides their missile armament, the Typhoon class features six torpedo tubes; two are designed to handle RPK-2 (SS-N-15) missiles or Type 53 torpedoes, and the other four are designed to launch RPK-7 (SS-N-16) missiles, Type 65 torpedoes, or mines. A Typhoon class submarine can stay submerged for periods up to 180 days in normal conditions, and potentially more if necessity arises (e.g. nuclear war).

Typhoon class submarines feature multiple pressure hulls that simplify internal design while making the vessel much wider than a normal submarine. In the main body of the sub, two Delta class 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.

Six Typhoon class submarines were built, with each carrying 20 R-39 missiles (SS-N-20) with a maximum of 10 MIRV nuclear warheads each. Originally, the submarines were designated by hull numbers only. Names were later assigned to the four vessels retained by the Russian Navy, which were sponsored by either a city or company. The construction of an additional vessel (hull number TK-210) was canceled and never completed. Only the first of these submarines to be constructed, the Dmitry Donskoi, is still in active service with the Russian Navy, serving as a test platform for the Bulava (SS-NX-30) missile currently under development. The Arkhangelesk (TK-17) and Severstal (TK-20) remain commissioned, though not currently active with the Russian fleet. All the R-39 missiles have been retired. The Typhoons are slated to be replaced with the Borei class starting in 2007.

In late December 2008 a senior Navy official announced that the two Akula-class submarines, the TK-17 and TK-20, that are in reserv would not be rearmed with the new Bulava SLBM missile system. They could however be modified to carry cruise missiles or to lay mines, or could be used in special operations. ^[6]

Typhoon-based cargo vessel

Main article: Submarine Cargo Vessel

The Submarine Cargo Vessel is a proposed idea by the Rubin Design Bureau where a Typhoon has its missile launchers removed and replaced with cargo holds. The projected cargo capacity of this configuration is 15,000 tonnes.

Notable popular culture

Typhoon class submarine, covered with ice

Probably the most well-known fictional Typhoon class was the stealth submarine Красный Октябрь (Krasnyy Oktyabr) (Red October). It is the subject of the Tom Clancy novel The Hunt for Red October and the movie adaptation of that book.

In the novel, the Red October used a drive system consisting of long shafts cut through the hull with impellers inside them, called a tunnel drive or caterpillar drive. In the movie, the caterpillar drive was instead said to be a Magnetohydrodynamic drive. In both the novel and the movie, the drive was said to be near-silent; this made the Red October a perfect platform for launching depressed-trajectory ballistic missiles at the United States. The book claims such launches would have minimal warning times and be extremely difficult to intercept.
