Nakajima Ki-106

The Nakajima Ki-106 was a version of the Ki-84 Army Type 4 Fighter constructed with a wooden fuselage in an attempt to save light alloys. Three airframes were completed by Ohji Koku K.K. (Prince Aircraft Co. Ltd) during 1945. These aircraft were powered by a 1,990hp Nakajima Ha-45 engine, and had larger vertical control surfaces than the standard Ki-84. The thick coat of lacquer also meant that they had a noticeably smoother finish.  Successful tests began in July 1945 but the war ended before the Ki-106 could enter production. The Ki-106 would have been slightly heavier (because of the lacquer) and slightly slower than the Ki-84.
