The Kawasaki Ki-61 was the only fighter with a liquid-cooled engine that the Japanese Army Air Force put into the field during World War II. It was this that made the Ki-61 Hien ("Swallow") so unlike the other Japanese planes that the Allies initially thought that it was German or Italian-made. While the engine was a license-built version of a German Daimler Benz engine, the rest of the aircraft was an all-Japanese design. The Ki-61, known as "Tony" in the Allied code, proved to be a match for Allied fighters, due chiefly to its particularly heavy armament, good protective armor, and high speed in dives. The Ki-61 was one of the few interceptors that could reach the same altitude as the the American B-29 Superfortresses. Because it was so successful a total of 3078 aircraft were built between August 1942 and August 1945. However, problems with production and with its engine kept it from being even more widely used during the war. The plane's engine problems included being difficult to tune and being subject to constant breakdowns. A solution to the engine problem was to substitute a more reliable radial engine for the liquid-cooled one. This caused a slight redesign of the fuselage, with the resulting aircraft type being designated the Ki-100, which turned out to be an even more outstanding fighter.
