In 1935, new international challenges pushed Soviet shipbuilding policy toward the development of modern heavy warships—a battleship for the Baltic Sea and a cruiser for the Pacific Ocean. It was planned for the new battleship to have nine 406 mm main guns housed in three turrets, twelve 152 mm secondary guns housed in six turrets, a 380 mm-thick armored belt, and a speed of at least 30 knots. In 1937, it was decided to continue improving the project by increasing its protection and armament. Later on, the project would be implemented in the form of the Sovetsky Soyuz-class battleships.
