The most modern, most powerful battleship of the Russian Federation.  Four battleships of this class will be completed in late 1921.  They are based on a 1914 concept of I.G. Bubnov, with modifications to reflect battleship design advances since 1914. These four ships form the most powerful Battle Squadron in the world.
