Nakajima Ki-115

The Nakajima Ki-115 Tsurugi was a one-man kamikaze aircraft developed by the Imperial Japanese Army in the closing stages of World War II in late 1945. The Imperial Japanese Navy called this aircraft Toka. As the Japanese High Command thought that Japan did not have enough obsolete aircraft to use for kamikaze attacks, it was decided that huge numbers of cheap, simple suicide planes should be constructed quickly in anticipation for the invasion of Japan. The war ended before the Ki-115 could be used.
