About the Japanese Submarine I-58The 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.
