Ushio (潮 "Tide"?) was the twentieth of twenty-four Fubuki-class destroyer destroyers, built for the Imperial Japanese Navy following World War I. When introduced into service, these ships were the most powerful destroyers in the world. They served as first-line destroyers through the 1930s, and remained formidable weapons systems well into the Pacific War. Ushio was one of only two of the 24 ships in its class to survive World War II, and it was also the only survivor out of the 22 combat ships involved in the Pearl Harbor assault force.
