Soviet doctrine for these vessels was to patrol under the Arctic ice cap and surface to launch SLBMs, avoiding the need to transit the GIUK gap and remaining safe from the enemy attack submarines and anti-submarine forces. Technically, Typhoons were also able to successfully deploy their long-range nuclear missiles while moored at their docks. The Russian Navy canceled its Typhoon modernization program in March 2012, stating that modernizing one Typhoon would be as expensive as building two new s. 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 their operational service lives. ဖော်ပြချက် Typhoon submarines are among the most quiet 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; four are designed to handle RPK-2 (SS-N-15) missiles or Type 53 torpedoes, and the other two 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 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. 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. 450px|Line drawing showing the starboard side of the Project 941 (Akula) Soviet ballistic missile submarine.

The project was developed with the objective to match the SLBM armament of s, capable of carrying 192 nuclear warheads, 100 kt each. However, at the time, state-of-the-art Soviet SLBMs were substantially larger and heavier than their American counterparts (the R-39 is more than two times heavier than the Trident I; it remains the heaviest SLBM in service worldwide). The submarine had to be scaled accordingly. တိုင်ဖွန်းအမျိုးအစားရေငုပ်သင်္ဘော စုစုပေါင်း ၆ စီးတည်ဆောက်ခဲ့သည်။ 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 order for an additional vessel (hull number TK-210) was canceled and never completed. Only the first of these submarines to be constructed, the Dmitriy Donskoy, is still in active service with the Russian Navy, serving as a test platform for the Bulava (SS-NX-32) missile which is currently under development. The Arkhangelsk (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 by the Borei class starting in 2010-11. In late December 2008, a senior Navy official announced that the two Typhoon-class submarines, the TK-17 and TK-20, that are in reserve 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. In late June 2009, the Navy Commander-in-Chief, Admiral Vladimir Vysotsky told reporters that the two submarines would be reserved for possible future repairs and modernization. In May 2010 the Navy Commander-in-Chief reported that Russia's Typhoon-class submarines would remain in service with the Navy until 2019. In September 2011, the Russian defense ministry decided to write off all Project 941 Akula nuclear-powered ballistic missile submarines until 2014. The reason for decommission of the world's largest submarines are restrictions imposed on Russia by the Strategic Arms Reduction Treaty and successful trials of new Borei-class submarine. However, according to other sources at the Russian defence ministry no such decision has been made and in that case the submarines would remain with the Russian Navy., Submarines TK-17 Arhangelsk and TK-20 Severstal will not be modernized as platforms for cruise missiles, but they will be kept in service with their previous armament, R-39 missiles. မူကွဲများ Typhoon-based 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.

In the novel, Red October used a drive system consisting of long shafts cut through the hull containing impellers called a tunnel drive or "caterpillar drive." In the movie, the caterpillar drive was instead said to be a magnetohydrodynamic drive with no moving parts. 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 movie features Red October as an upgraded Typhoon-class submarine with additional length and potentially a towed array sonar (the distinctive "bulb" seen on top of the rudder houses). The latter presumption is questionable as the existence of a functional towed array (thus functional passive sonar capability astern) would eliminate the need for the boat to clear its baffles by maneuvering (executing a "Crazy Ivan"); Though the baffle clearing maneuver might well have been employed per Soviet doctrine and sheer habit, the 688 (Los Angeles) class attack submarine USS Dallas (SSN-700) (close aboard in October's baffles) would have been almost surely counter detected by any functional towed array prior to intentionally cavitating. National Geographic In 2008 National Geographic released a documentary about the scrapping of one of the Typhoons in the series "Break It Down". This ship is TK-13, which was scrapped over the time period 2007-2009.
