Nakajima (JAAF Ki-84, type 4) Hayate (Hurricane): ‘Frank’ (Richard M. Bueschel)  First ordered by the JAAF in May 1942, ten months later the prototype (8401) was completed and five weeks after completion (April 1943) took to the air.  Second model (8402) which incorporated numerous changes was completed in June and flew in August.  A third experimental machine (8403) quickly followed.  The new fighter had a top speed of 388 mph, which was faster than previous JAAF fighters but did not have the performance hoped for.  There were, however, considerably production advantages.
