Shch-310 was a Series V-bis-2 Shchuka-class submarine built for the Soviet Navy in the 1930s under the name of Belukha, but was renamed Shch-310 while under construction. Completed in 1936, she was assigned to the Baltic Fleet. The boat played a minor role during the 1939–1940 Winter War with Finland and in the Second World War. Shch-310 participated in the defense of the Soviet Union after the Axis powers invaded in June 1941 (Operation Barbarossa), but only made six patrols during the war, sinking three or four ships. Shch-310 was renamed S-310 in 1949. She was stricken from the navy list in 1953 and was either scuttled during a training exercise or scrapped in 1958.
