Ussr Cruiser
Before the Great Patriotic War started, the Soviet Navy's authorities took measures to strengthen their fleet. Unfinished heavy cruiser Lützow was purchased from Germany in 1940 and renamed Petropavlovsk. The ship, which was in a state of 70% completion, participated in the Siege of Leningrad. She was renamed Tallinn, and it was planned to complete her after the war, adding mechanisms from cruiser Seydlitz and 180 mm guns, but those plans never came to fruition.
