The action of 24 July 1945 was one of the final naval battles during the Pacific Theater of World War II. In an attempt to destroy as many allied ships as possible, the Imperial Japanese Navy began arming their submarine fleet with manned torpedoes called kaitens. The Action of 24 July 1945 concerns the battle between a convoy of U.S. Navy warships off Luzon and the Japanese submarine I-53 and her kaitens.[3][4]
