Soviet submarine Shch-307
1934 Shchuka-class submarine

Shch-307 (Russian: Щ-307) was a Series V-bis-2 Shchuka-class submarine built for the Soviet Navy during the 1930s with the name of Treska. Renamed Shch-307 while under construction in 1934, she was completed the following year. The boat was assigned to the Baltic Fleet and participated in the defense of the Soviet Union after the Axis powers invaded in June 1941 (Operation Barbarossa). The ship played a minor role during the evacuation of Tallinn, Estonia, in August. Shch-307 made only four war patrols during the war, but sank a German submarine in 1941. After the war, the boat was decommissioned in 1948, renamed PZS-5 and converted into a floating charging station the following year. She was stricken from the navy list in 1957 and subsequently scrapped, although her conning tower was preserved as a memorial.
Background and description
The Series V-bis-2 Shchuka-class submarines were improved versions of the Series V-bis boats placed into production because Soviet shipyards were having difficulties integrating new German technology. The boats displaced 591 metric tons (582 long tons) surfaced and 708 t (697 long tons) submerged. They had an overall length of 58.75 meters (193 ft), a beam of 6.2 meters (20 ft 4 in), and a mean draft of 4.22 meters (14 ft).
