The Nakajima Ki-87 was designed to meet a 1942 specification for a heavily-armed high-altitude fighter. However, development problems (particularly with the unusual landing gear retraction mechanism and with the aircraft's turbosuperchargers) resulted in only one prototype being completed by February 1945. Flight tests in April 1945 showed that Ki-87 could have been a better performer than the Ki-84, though an even more improved version was on the drawing boards when the war ended.
