Soryu, a 18,800-ton aircraft carrier built at Kure, Japan, was completed in December 1937. One of six carriers that delivered the Pearl Harbor attack on 7 December 1941, she also participated in other early Pacific War operations. Soryu was sunk on 4 June 1942, during the Battle of Midway, after SBD "Dauntless" aircraft from USS Yorktown (CV-5) hit her with several bombs.
