Kawasaki Ki-148

The Kawasaki I-Gо̄ Model 1 Otsu (No.1 Model 1B), otherwise known as Ki-148 was a World War II Japanese guided air-to-surface missile designed in 1944. Developed alongside its sister project the Mitsubishi I-Gо̄ Model 1 Kо̄ and the later Tokyo Imperial University designed I-Gо̄ Model 1 Hei, the Ki-148 was a simple radio-controlled guided missile propelled by a liquid rocket engine generating 1.47 kN (330 lbf) of thrust for up to 80 seconds. Compared to the Ki-147, the Ki-148 was physically smaller and carried a 300 kg warhead versus the 800 kg warhead of the Ki-147.

Test trials were carried out in late 1944 and the weapon was quickly ordered by the war ministry. Launched during tests from a modified Kawasaki Ki-48 light bomber, its standard mother aircraft was to be the modern Kawasaki Ki-102 attack aircraft. Although approximately 180 missiles were built, none saw service before the end of World War II.
