The project of a Sovetsky Soyuz-class battleship incorporated considerable upgrades in the 1950s. The main battery mounts have been replaced by 457 mm twin-gun mounts—one of the options considered for the project during the development of Project 24. The medium-caliber guns and long-range AA artillery have been replaced by 152 mm dual-purpose mounts, while the small-caliber AA artillery is represented by ZIF-75 and ZIF-31B gun mounts. Such a ship could well have been handed over to China as part of Soviet assistance in their navy development program.
