with a view to greatly expand the Japanese Empire. Japan withdrew from the League of Nations in 1934, renouncing its treaty obligations. After withdrawing from the Washington Naval Treaty, which limited the size and power of capital ships, the Imperial Japanese Navy began their design of the new "Yamato" class of heavy battleships. Their planners recognized Japan would be unable to compete with the output of U.S. naval shipyards should war break out, so the 70,000 ton vessels of the "Yamato" class were designed to be capable of engaging multiple enemy battleships at the same time.

Japanese battleship Yamato [SEP] Design and construction
The keel of "Yamato", the lead ship of the class, was laid down at the Kure Naval Arsenal, Hiroshima, on 4 November 1937, in a dockyard that had to be adapted to accommodate her enormous hull. The dock was deepened by one meter, and gantry cranes capable of lifting up to 350 tonnes were installed. Extreme secrecy was maintained throughout construction, a canopy even being erected over part of the drydock to screen the ship from view. "Yamato" was launched on 8 August 1940, with Captain (later Vice-Admiral) Miyazato Shutoku in command. A great effort was made in Japan to ensure the ships were built in extreme secrecy to prevent American intelligence officials from learning of their existence and specifications.
