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.
