Project history: Well-known "Shchukas" ("pikes"): the most mass series of Soviet WWII-era submarines. They were designed since 1928 as patrol small (later medium) submarines for Baltic. The big effect on the design was rendered by raised British submarine L55 from which there was borrowed architectural type: saddle-tank with bulge tanks, and a hull form. III series submarines differed by only one 45mm gun, all subsequent submarines received two, nevertheless, weakness of artillery armament during war remained one of the main lacks of the project.
Maximal diving depth for all series was 90m.
Modernizations: 1939, Shch-304: - hydrophone; + Orion sonar
1940-1941, Shch-301, Shch-302, Shch-303: - hydrophone; + Mars-12 hydrophone
1944, Shch-303: + type 129 sonar
Naval service: Shch-301 was lost 28.8.1941 on a mine en route from Tallinn to Kronshtadt. Shch-302 was lost presumably 11-12.10.1942 on mines in Gulf of Finland or sunk 14.10.1942 by Finnish SB bomber at Porkkala-Udd. Shch-304 was lost after 29.10.1942 by unknown cause.
