Shch-421 was a Shchuka-class submarine of the Soviet Navy. She served in the Northern Fleet during World War II. She was led by commander Nikolai Lunin, before he was replaced by his second-in-command Fyodor Vidyayev.

Service history

The submarine operated in the Northern Fleet and made torpedo attacks during 1941 and 1942, missing multiple targets and sinking one.^{[citation needed]} On 19 February 1942, she ran aground in Skorbeevskaya Bay. She was refloated on 6 March and taken in to Polyarny for repairs.^[2] On 8 April 1942 the submarine suffered heavy damage in a minefield: with no more power and close to enemy shores, the crew built a sail out of the canvas cover and managed to move away from the dangerous area. ShCh-421 was then found by K-22. All crew was taken onboard K-22 and the crippled submarine was sunk with a torpedo.
