The Mitsubishi I-Gо̄ Model 1 Kо̄, 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 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. 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.
