The Nakajima Ki-116 was a late-World War II aircraft developed for the Imperial Japanese Army Air Force. It was essentially a Ki-84 Hayate with the Nakajima Ha-45 engine replaced with a Mitsubishi Ha-112. The design was handled by Mansyū Aircraft in Manchukuo, and thus it is often designated Mansyū Ki-116.

Design and development[edit]

The Ki-116 was essentially the last variant of the Nakajima Ki-84 Hayate to enter flight trials. It was originally the fourth Mansyu-built Ki-84-I, adapted to take a 1,500 hp Mitsubishi Ha-112-II (aka Kinsei 62) engine, the same engine used in the Kawasaki Ki-100, driving a three-blade popeller borrowed from a Mitsubishi Ki-46-III Dinah. This conversion proved to be very successful, a reduction of 1,000 lb in empty weight being registered. The aircraft was still undergoing tests at the time of Japan's final defeat.[1][2][3] It appeared somewhat longer and had an increased tail surface area compared to the original Ki-84.[3][4][5]

This aircraft was created as a fighter-interceptor. There is no indication that it was intended for the Special Attack suicide role (shimbu-tai).

One aircraft was built at Manshūkoku Hikōki Seizo KK at their plant in Harbin in 1945.
