The Shchuka-class submarines, also referred to as Sh or Shch-class submarines, were a medium-sized class of Soviet submarines, built in large numbers and used during World War II. "Shchuka" is Russian for pike. Of this class, only two submarines entered service after 1945, although they were launched before the war.
Development
On 23 January 1930, the USSR Revolutionary Military Council adapted a proposed submarine concept that were to "execute positioning service on closed theatres". Plans were made to construct up to 200 submarines in three main versions, the later ones would be larger and with longer range than the previous versions. However, due to the outbreak of World War II, only 88 submarines were commissioned. It was still to be the second most numerous submarine class of the Soviet Navy. Seven ship construction yards were involved in the program - No. 189, 190, 194 in Leningrad, No. 112 in Gorky, No. 200 in Nikolaev and No. 202 in Vladivostok. The name of the class was taken from the individual name of the first submarine Shch-301 Shchuka. Their numbering depended on which Soviet fleet they belonged to: the 100-series belonged to the Pacific Fleet, the 200-series to the Black Sea Fleet, the 300-series to the Baltic Fleet, and the 400-series to the Northern Fleet. There were however some special cases, i.e. the Northern Fleet submarineShch-424 was renamed Shch-321 when she was transferred to the Baltic Fleet via the Stalin Canal. The conning tower had brass symbols as identifiers.
Operational service
The Shchukas suffered heavy losses during the war. The Baltic, Black Sea and Northern Fleets lost 60–70% of their submarines. However, the submarines of the Pacific Fleet did not suffer any losses to the Japanese due to the tranquil nature of the theatre. Three submarines were, however, lost to non-combat reasons. In all, 35 Shchuka-class submarines were lost, the vast majority during World War II. The last surviving submarines of the class in the Soviet Navy were decommissioned in the mid-1950s and scrapped during the following years, but two submarines of this class, along with two Soviet M-class submarines were supplied to People's Liberation Army Navy in June, 1954, thus becoming the foundation of the submarine force of the People's Republic of China. However, the two Shchuka-class submarines were not sold, but instead, loaned to China for training Chinese crews and were thus not given new names like the M-class submarines.
