The Shchuka-class submarines (Russian: Щука), 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 (411 and 412) entered service after 1945, although they were launched before the war.
