The Nakajima Ki-115 Tsurugi (剣, "sabre")[5] is a one-man kamikaze aircraft that was developed by the Imperial Japanese Army Air Force during the closing stages of World War II in 1945.

[2][3] The aircraft had a top speed of 550 km/h (342 mph) and could carry a bomb weighing as much as 800 kg (1,760 lb), large enough to split a warship in two.

However, as it was otherwise unarmed and heavily laden with its bomb, it would have made an easy target for enemy fighter aircraft.

Tsurugi had very poor take-off and landing performance and could not be safely flown by anyone other than experienced pilots.
