Rikugun Ki-202
The Rikugun Ki-202 Shūsui Kai (秋水改, Sharp Sword improved) was a direct development of the German Messerschmitt Me 163 Komet rocket-powered interceptor aircraft. None were produced before Japan's surrender that ended World War II. In a split from the development of the Mitsubishi J8M/Ki-200 Shūsui, the IJA instructed Rikugun to develop a new design based on the Me 163, independent of the IJN's J8M. A fundamental shortcoming of the Me 163, and all other aircraft based on it, was extremely limited endurance, typically only a few minutes.
