USS Ward was laid down as a 1,247-long-ton (1,267 t) Wickes-class destroyer (designated DD-139) in the United States Navy during World War I, later converted to a high speed transport (designated APD-16) in World War II. She was responsible for the first American-caused casualties in the Pacific in World War II when she engaged and sank a Japanese midget submarine before Japanese aircraft arrived in the attack on Pearl Harbor, killing both crewmen on board.
