Mitsubishi Ki-147
The Mitsubishi I-Gō Model 1 Kō (No.1 Model 1A), otherwise known as Ki-147, was a radio-guided air-to-surface missile developed by Japan in World War II. The Imperial Japanese Army's primary envisaged the missile as a stand-off weapon against U.S. and Allied naval ships, equipped with an 800 kg warhead. The Ki-147 was planned to be installed on the Mitsubishi Ki-67 heavy bombers which would serve as the control aircraft.
