History
As quoted from the introduction in the book "The Nakajima Ki-84 Hayate, known as "Frank" in allied jargon, was one of the best IJAAF (Imperial Japanese Army Air Force) fighters during the final year of the Pacific war. Featuring an enclosed cockpit and retractable landing gear, this all-metal cantilever low-wing monoplane of an elegant body was the successor of the previous Nakajima fighters - Ki-43 Hayabusa and Ki-44 Soki. The Ki-84 proved it's value fighting in China and the Philippines, although the highest number of these machines were lost there, too. When in the hands of an experienced pilot, it was a good match for the best of Allied fighter aircraft. After the war a small number of Ki-84s served with the Chinese air forces, taking part in the civil war of 1945-1949".
