Faced with raids by U.S.-built B-29 high altitude bombers over its cities, the Japanese military attaches in Germany arranged to purchase manufacturing licenses for both the Me 163 Komet and its Walter HWK 109-509 rocket engine for the sum of 20 million Reichsmarks.
The task of designing and producing the J8M1 Shusui, based on the Me 163 Komet, was entrusted to the Mitsubishi company who also produced the well-known Zero fighter and Betty bomber. Both Army (designated Ki-200) and Navy J8M1 Shusui (Sword Stroke) versions were envisioned, but the popularity of the Shusui name eventually caused the Army to adopt the name for its model as well.
The Japanese version of the rocket motor was designated Toko Ro.2 and produced over 3,300 Ibs of thrust. As with most Japanese adaptations of foreign technologies, the engine was modified for their unique needs.
Although it was well-known that the Me 163 had severe operational problems and limited combat success, work on the Shusui continued to the end of the war. Fortunately for B-29 crews, the J8M1 did not become operational before cessation of hostilities.
The Mitsubishi J8M1 Shusui has the distinction of being the first aircraft acquired by the Museum's founder Ed Maloney.
It is one of only two surviving J8M1 aircraft in world.
