The Yokosuka MXY9 Shuka (秋火, "Autumn fire") was a projected development of the MXY8 training glider, adding a small thermojet-style jet engine, the Tsu-11. It was intended to provide further training for pilots who were to fly the Mitsubishi J8M and Mitsubishi Ki-200 rocket-powered interceptor aircraft.
None were built prior to Japan's surrender and the end of World War II.
