The Japanese mini submarines of the Kō-hyōteki class, participated in several attacks during second world war. They were carried on the deck of larger submarines, and launched for attacks when they arrived at the designated targets. They had no names, and was often called the same as the submarines who carried them. One of these submarines were beached under the attack on Pearl Harbor in December 1941, and three were later sunk outside Australia. Three such submarines attacked Sydney harbor 31.May 1942. Two of them were almost immediately spotted and sunk, but the third one attacked and sunk the Australian depot ship HMAS Kuttabul. What thereafter happened to her is uncertain. The wreck was located in November 2006, and rest today on a depth of 54 meter at Bungan Head outside Newport.
