On 4 April 1942, the I Fliegerkorps launched a major attack on the Soviet naval forces in Leningrad: 62 Ju 87s, 33 Ju 88s, and 37 He 111s struck the ships in the harbor. Petropavlovsk was hit once (credited by Hans-Ulrich Rudel), suffering serious damage[22], and sunk. The Soviet Navy raised the ship on 17 September 1942 and towed her to the Neva where she was repaired.[6] Renamed Tallinn in 1943, the ship returned to service to support the Soviet counter-offensive to relieve the Siege of Leningrad in 1944.
