Yamato-class battleship
 The Yamato-class battleships (大和型戦艦 Yamato-gata senkan) were battleships of the Imperial Japanese Navy (IJN) constructed and operated during World War II. Displacing 72000 long tons (73000 t) at full load the vessels were the heaviest and most powerfully armed battleships ever constructed. The class carried the largest naval artillery ever fitted to a warship nine 460-millimetre (18.1 in) naval guns each capable of firing 1360 kg (3000 lb) shells over 42 km (26 mi).
