Nakajima Ki-116

The Nakajima Ki-116 was a late World War II fighter-interceptor developed for the Imperial Japanese Army Air Force, essentially a Nakajima Ki-84 Hayate with its Nakajima Ha-45 engine replaced by a Mitsubishi Ha-112. Design work was handled by the Manchuria Airplane Manufacturing Company, known as Manshu or Mansyu, in Manchukuo, which is why it is often called the Mansyu Ki-116. It was converted from the fourth Manshu-built Ki-84-I to take a 1,100 kW Mitsubishi Ha-112-II (Kinsei 62), the engine of the Kawasaki Ki-100, driving a three-blade propeller borrowed from a Mitsubishi Ki-46-III. The change cut empty weight by about 450 kg, and the aircraft looked somewhat longer with a larger tail surface area than the Ki-84. One aircraft was built at the company plant in Harbin in 1945 and was still under test when Japan was defeated. There is no indication that it was meant for the suicide role.
