Fate

On January 11, 1962, the Soviet Foxtrot class submarine B-37 exploded as the result of a fire which detonated all torpedo warheads in the submarine. The S-350, which was moored next to B-37, was heavily damaged. Eleven crew members of the S-350 were killed. The submarine was salvaged, repaired and returned to service in 1966.^[1]
