The Rikugun Ki-202 "Shūsui-Kai" (Japanese: 三菱 Ki-202 秋水改 , translated as "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. Using only the above description and what you know about the world, "The Rikugun were produced before Japan admitted defeat." is definitely correct, incorrect, or inconclusive?
