, and air-cooled supercharged engine Nakajima Ha-44-12. Armed with two synchronized 20mm cannon Ho 5 and 30 mm cannons Ho 105 wing.
In July 1943, we ordered three prototypes Ki-87, but only one was built. He first flew in April 1945 and the end of the war only five times. After the war, he was captured by the US military.
The next phase of the project stage of the project were Ki-87 II with engine Nakajima Ha-46 to 11 with an output of 3000 k turbodmychalem at the bottom of the hull.
