The Yokosuka MXY-7 Ohka was a desperate attempt during the Second World War by the Japanese to damage enemy ships through a suicide "Kamikaze' attack. The Ohka model 11 had a rocket engine and "human guidance" and a large warhead in the nose. It was usually carried underneath a Mitsubishi G4M2e "Betty" to within range of its target. On release, the pilot would first glide towards the target and when close enough he would fire the Ohka's three solid-fuel rockets and fly very fast to the target. The warhead would explode on impact.
The Ohka model 22 had a reciprocating more conventional jet engine but this type never was used operational.
