Renamed Petropavlovsk in September 1940, work on the ship was delayed by poor German-Soviet co-operation in crew training and provision of technical literature to enable completion of the ship, which was being carried out in the Leningrad shipyards. Still unfinished when Germany invaded the Soviet Union in June 1941, the ship briefly took part in the defense of Leningrad by providing artillery support to the Soviet defenders. She was heavily damaged by German artillery in September 1941, sunk in April 1942, and raised in September 1942.
