K-3 Leninsky Komsomol

K-3 "Leninsky Komsomol" was the first Soviet nuclear-powered submarine, which for the first time set sail under nuclear power on July 4, 1958. The submarine received its honorary name on October 9, 1962, in memory of the submarine "M-106" of the Northern Fleet, which was lost in 1943. During its service, the ship completed six combat missions and four long-distance voyages, covering 128,443 nautical miles, and in 1967 it survived a fire in the Norwegian Sea that claimed the lives of 39 people. Since July 2023, the submarine has been one of the main exhibits at the Museum of Naval Glory in Kronstadt.
