Named after the ancient Japanese Yamato Province, Yamato was designed to counter the numerically superior battleship fleet of the United States, Japan's main rival in the Pacific. She and her sister ship, Musashi, were the heaviest and most powerfully armed battleships ever constructed, displacing nearly 72,000 tonnes (71,000 long tons) at full load and armed with nine 46 cm (18.1 in) Type 94 main guns, which were the largest guns ever mounted on a warship. Yamato ( 大和) was the lead ship of her class of battleships built for the Imperial Japanese Navy (IJN) shortly before World War II. Sunk by American planes during Operation Ten-Go, 7 April 1945
