The Kawasaki Ki-100 was a fighter aircraft used by the Imperial Japanese Army in World War II. The Japanese Army designation was "Type 5 Fighter". No Allied code name was assigned to this type, although it may have been misidentified as a Tony due to the similar profile and appearance.
An overall assessment of the effectiveness of the Ki-100 rated it highly in agility and a well-handled Ki-100 was able to out-manoeuvre any American fighter including the formidable P-51D Mustangs and the P-47N Thunderbolts which were escorting the B-29 raids over Japan by that time, and was comparable in speed especially at medium altitudes. In the hands of an experienced pilot, the Ki-100 was a deadly opponent and together with the Army's Ki-84 and the Navy's Kawanishi N1K-J, the only other Japanese fighters being able to defeat the latest Allied types.
