The Red October - 
Red October (Russian: Красный Oктябрь, "Krasniy Oktyabr") is a fictitious modified Typhoon class submarine in the Tom Clancy novel The Hunt for Red October and the film that followed. She was built with a revolutionary stealth propulsion system called a "caterpillar drive", which is described as a pump-jet system in the book. In the film however, it is shown as being a magnetohydrodynamic drive.
In the film, the Red October appears much like a standard Typhoon-class submarine though it has a number of significant differences. The aft section of the submarine contains two ducts for the caterpillar drive. The upper rudder carries a towed sonar array which typical Typhoon-class submarines do not feature. Also the bridge tower of the submarine is taller and more simplified, with no large bulging lower section of a standard Typhoon bridge tower, but instead a much smaller bulge. The difference in appearance of the bridge tower may have been an error in the design of the model of the Red October as earlier on in the film, schematics of a Typhoon-class submarine are shown which display a standard Typhoon bridge tower but also carry the sonar array attached to the rudder as on Red October. Red October is also longer due to additional ballistic missile launch tubes.

Typhoon Class Submarine -


The Project 941 or Akula, Russian "Акула" ("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 tons, the Typhoons are the largest class of submarine ever built, large enough to accommodate decent 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" ("тайфун") by Leonid Brezhnev in a 1974 speech while describing a new type of nuclear ballistic missile submarine.


The Russian Navy canceled its Typhoon modernization program in March 2012, stating that modernizing one Typhoon would be as expensive as building two new Borei-classsubmarines. 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. 

Typhoon submarines are among the quietest Russian sea vessels in operation, being quieter and yet more maneuverable than their predecessors. 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 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.



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.
