S-7 was a Stalinets-class submarine of the Soviet Navy. Her keel was laid down by Krasnoye Sormovo in Gorkiy on 14 December 1936. She was launched on 5 April 1937 and commissioned on 30 June 1940 in the Baltic Fleet. During the WW2, the submarine was under the command of Captain Sergei Prokofievich Lisin and took part in the Soviet submarine campaign on 1942 in Baltic Sea. S-7 scored victories, but was sunk in action.
Loss
While attempting a new campaign (after the successful summer one), S-7 was attacked, torpedoed and sunk by the Finnish submarine Vesihiisi.
Four crewmembers were saved and captured, including the commander Lisin. Commander Lisin was believed KIA and was awarded post-mortem as Hero of the Soviet Union. Once Finland switched sides and joined the Allies, Lisin was freed and was sent by Soviets to an NKVD special camp. However his accusations were dropped (he kept the title of Hero) and was sent as military instructor to an officer school.[1]
Service history
Submarine made all the victories in summer 1942, scoring a good success, against the German-Swedish iron ore shipping lines (the main target of 1942 Soviet submarine campaign). S-7 was lost when attempted to repeat the feat, in fall.
