The Japanese Navy included five Type A midget submarines in the Pearl Harbor raid of 7 December 1941. Transported on board large I type submarines, the midgets were launched near the entrance to Pearl Harbor the night before the attack was to begin. One, spotted trying to enter the harbor before dawn, was attacked and sunk by USS Ward (DD-139) in the first combat action of the as yet unopened Pacific War. At least one of the midgets was able to enter the harbor and was sunk there by USS Monaghan (DD-354). Another, the Ha-19, unsuccessful in its attempts to penetrate Pearl Harbor, drifted around to the east coast of Oahu and was captured there the day after the attack.
