The Kawasaki Ha-140 was a twelve-cylinder inverted "V" engine with bore of 154mm (6.06 inches) and stroke of 4.06 inches (103mm) for a nominal power rating of 1450 horsepower (1081 kW). It was based on the German DB 605 engine. The engine was used on the Ki-61 "Tony", but proved so unreliable (having tight tolerances that stretched the capacity of Japanese manufacturing) that the "Tony" was redesigned to use a radial engine, the Ki-100.
