Kawasaki Ki-148

Kawasaki Igo-1-B, otherwise known as Kawasaki Ki-148 was a World War II Japanese guided air-to-surface missile designed in 1944. Developed along its sister projects of Mitsubishi Igo-1-A and Tokyo Imperial University-designed Igo-1-C, the Igo-1-B was a simple radio-controlled guided bomb propelled by a rocket engine generating 150 kilograms (330 lb) of thrust for up to 80 seconds.^[1]

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 heavy fighter. Although approximately 180 missiles were built, none saw service before the end of World War II.^[2]
