Added from my previous comment dated
20 Feb 2009:


The Kawasaki Ki-100 was an air-cooled radial engine variant of the Ki-61 in-line liquid-cooled engine, "Tony" used by the Imperial Japanese Army Air Force (IJAAF).

Developed due to shortages caused by B-29s
bombing the engine production plant for the Ki-61, Kawasaki was left with 280 airframes
without engines, a solution was found, by
using the Mitsubishi Ha-112 or Ha-33 air-cooled radial engine, of 1,500hp for takeoff
The engine led to improved power and maneuverability, but its high-altitude performance against US B-29s was limited by the lack of a super-charger, nevertheless the Ki-100 was an excellent dog-fighter holding its own, against the P-51 Mustang, the P-47 Thunderbolt and the F6F Hellcat.

In the hands of an experienced pilot, the Ki-100 was a deadly combat aircraft.
Armed w/2x20mm cannons and 2x12.7mm machine guns with a top speed of 580km/h or 360mph


During WWII the Japanese captured different types of Allied aircraft, among them were the
North American P-51 Mustang and Grumman F6F Hellcat.
The most experienced instructors and combat veterans, would fly the captured Allied fighters in mock combat, against other Japanese fighter aircraft, at Army bases throughtout Japan the training was used to
show the pilot's how to best combat these
enemy fighters.
The Ki-100 was never given a Allied code name, it was just designated by its Japanese aircraft number, the Ki-100.


At wars end the US shipped four Ki-100s for
tests, among the 40 Japanese aircraft sent to the United States after WWII, only 8 have survived.

In 1959 the last Ki-100 was broken up, due to being left outside to rot.
Another Ki-100 is maintained in beautiful condition at the RAF Museum, Hendon outside of London.
