After purchasing cruiser Lützow from Germany and renaming her Petropavlovsk, the question of whether to build more advanced ships of the same type arose. The development of a cruiser codenamed 82 was commissioned. In 1943, a project was developed that took military experience into account: the main armament was represented by 220 mm guns, and the secondary battery was represented by multipurpose 130 mm guns. While the ship was never implemented in this configuration, later improvements to the design led to the emergence of the Stalingrad-class heavy cruisers.
