About the Ki-84 "Frank"

The Nakajima Ki-84, known as the Type 4 fighter by the Japanese army, was nicknamed the 'Frank' by the US pilots who fought against them. The aircraft was designed as a replacement for the Ki-43 'Oscar', which was just entering service when the Ki-84 design process started in 1942. The design imperative was to improve the already capable Oscar by increasing its armament, improving its climbing performance and making it more durable. The Nakajima design team achieved these objectives and produced a very capable fighter.

However, the engine design had a very complicated direct injection system which was difficult to maintain, especially late in the war, with US air efforts making resupply of remote Japanese outposts difficult. While it was probably the best Japanese fighter, it could debateably outclass a mustang, these maintenance issues made them difficult to keep in the air. Close to 3000 were made and saw combat in China as early as March 1944. Most were utilized in the Phillipines and in the defense of Okinawa and Japan.
