Several experimental versions of the Ki-67 were designed in the last years of the war. The only design of any consequence was the the transformation of the Ki-67 to a heavy fighter. Twenty-two planes of this model, known as the Ki-109, were built. The only differences from the original were in the armament and the forward part of the fuselage. The glassed-in nose was replaced by a faired 75mm cannon. This gun had 15 projectiles. It was to be used against the American B-29s at high altitude. Test results were satisfactory, but by the time a sufficient number of aircraft were ready, there had been a radical change in Allied tactics and the planes were no longer needed, because the B-29s began making night raids at low altitude.
