The November class, Soviet designation Project 627 Kit (Russian: Кит, lit. 'whale', NATO reporting name November)^[2] was the Soviet Union's first class of nuclear-powered attack submarines, which were in service from 1958 through 1990.^[3][4] All but one have been disposed of,^[5] with the K-3, the first nuclear-powered submarine built for the Soviet Navy, being preserved as a memorial ship in Saint Petersburg


This class of submarines was built as a result of a 1952 requirement to build an attack submarine with the ability to fire nuclear-tipped torpedoes at coastal American cities.^[7]

More than 135 Soviet organizations (20 design bureaus, 35 research institutes, 80 works) participated in the design and construction of this completely new type of submarine in 1952–1958. The chief designer was V.N. Peregudov and the research supervisor was academician A.P. Alexandrov. The class was originally tasked with entering American naval bases and using the battery-powered T-15 torpedo with thermonuclear warhead, to destroy them once in range. (The T-15 torpedo had the following specifications: calibre 1,550 mm, length 23.5 m, range 40–50 km.) However, after expert opinions of Soviet naval specialists were considered, the role of the class changed to torpedo attacks on enemy warships and transport ships during actions along the ocean and distant sea routes. Reflecting this change of mission, the final design of Project 627 was developed with eight 533 mm torpedo tubes instead of the initial plan for one 1,550 mm and two 533 mm torpedo tubes. Project 627/627A submarines could launch torpedoes from 100 m depth. By 1963 this class was still in service but had been overtaken by later technolog
