IJN Shinano （山户班）

Shinano (信濃), was an aircraft carrier built by the Imperial Japanese Navy (IJN) during World War II, the largest such built up to that time. Laid down in May 1940 as the third of the Yamato-class battleships, Shinano's partially complete hull was ordered to be converted to a carrier following Japan's disastrous loss of four fleet carrie at the Battle of Midway in mid-1942. Her conveion was still not finished in November 1944 when she was ordered to sail from the Yokosuka Naval Aenal to Kure Naval Base to complete fitting out and trafer a load of 50 Yokosuka MXY7 Ohka rocket-propelled kamikaze flying bombs. Hastily dispatched, she had an inexperienced crew and serious design and cotruction flaws, lacked adequate pumps and fire-control systems, and did not carry a single aircraft. She was sunk en route, 10 days after commissioning, on 29 November 1944, by four torpedoes from the U.S. Navy submarine Archerfish. Over a thousand sailo and civilia were rescued and 1,435 were lost, including her captain. She remai the largest wahip ever sunk by a submarine.[1]
