The Project 941 Akula heavy missile submarine cruisers (SSBN Typhoon according to NATO codification) are a series of Soviet and Russian nuclear-powered strategic submarines of the third generation. The main armament is 20 ballistic missiles R-39 (RSM-52). The world's largest submarines. In total, six ships were built, as of 2020, three ships have been scrapped, one (TK-208 Dmitry Donskoy) is in service as an experimental ship, two more - TK-17 and TK-20 are in reserve. for the design of the TRPKSN was issued in December 1972, the chief designer of the project was appointed SN Kovalev. The new type of submarine cruisers was positioned as a response to the US construction of the Ohio-class SSBN (the first boats of both projects were laid down almost simultaneously in 1976). The dimensions of the new ship were determined by the dimensions of the new solid-propellant three-stage intercontinental ballistic missiles R-39 (RSM-52), with which it was planned to equip the boat. Compared with the Trident-I missiles, which were equipped with the American Ohio, the R-39 missile had the best characteristics of flight range, throw weight and had 10 blocks versus 8 for Trident. However, at the same time, the R-39 turned out to be almost twice as long and three times heavier than its American counterpart. To accommodate such large missiles, the standard SSBN layout scheme did not fit. On December 19, 1973, the government decided to start work on the design and construction of a new generation of strategic missile carriers.
