Mitsubishi Ki-147

The Mitsubishi I-Gо̄ Model 1 Kо̄ (No.1 Model 1A), otherwise known as Ki-147 was a radio-guided air to surface missile developed by Japan in World War II.

[1] The Imperial Japanese Army's main envisioned role for the platform was for strikes against U.S. and allied ships.

The Ki-147 was planned to be installed on Ki-67 heavy bombers which would act as the control platform.

[2] The Ki-147 was developed during 1944-1945 along with its sister project of the smaller Kawasaki I-Gо̄ Model 1 Otsu (Ki-148) radio-guided air-to-surface missile and the later Tokyo Imperial University designed I-Gо̄ Model 1 Hei.

Drop tests were later conducted, but due to malfunction of the gyro stabilizer and difficulties in adjusting the radio equipment for operation, it was not put into practical use.
