In 1934, Japan decided to abandon the displacement limits set by the Washington Naval Conference in order to surpass U.S. battleships in combat capability. The Imperial Japanese Navy General Staff issued an order to design a battleship with nine 460 mm guns and a displacement of 69,500 tons. The presented projects had three triple-gun turrets mounted on the bow, housing 410 mm guns. The preferred project had a combined diesel and steam turbine propulsion plant. While the design was never implemented, further development led to the creation of the Yamato-class battleships.
