For more than 60 years after the Japanese attack on Pearl Harbor, the USS Ward’s crew had their doubters. If they had sunk a Japanese sub, where was it? Even famed undersea explorer Robert Ballard came up empty in a 2000 search. Then in 2002 a team of scientists on a routine mission in two submersibles discovered the midget sub 1,200 feet underwater, some three miles south of the harbor. Its hatch was closed, its two torpedoes retained—and its conning tower had a shell hole. Terry Kerby, pilot of one of the submersibles, called it a “sobering moment, realizing that was the shot that started the Pacific War.” Hawaii Undersea Research Library
