The I-58 was laid down in Yokosuka Navy Yard in September 1944. The vessel
carried a Type 0 small reconnaissance seaplane E-14 (Glen) and a catapult to
launch it. The primary weaponry of the I-58 consisted of six torpedo tubes,
three on each side of the bow. It also served as the mother ship for the Kaiten
human torpedoes. On the night of July 30th 1945, it attacked the U.S. Navy heavy
cruiser Indianapolis with a salvo of six regular torpedoes. Two of those struck
the cruiser and she sunk about fifteen minutes later.
