P loving of the Ki-84 (in one of these paches in the place to make things as ju to load bombs variaçao of the equal Ki could place one to that the text shows! ) Its maneuverability and reason of ascent were inquestionavelmente superior that the North American P-51H Mustang and Republic P-47N Thunderbolt that were the disposal of the USAAF in the theater of war of the Pacific. The Japanese Imperial Navy introduced in service the KI-84 in the 1944 summer, was its new interceptador/caça-bomber known monorank as Hayate. Found in all the operational zones, it was highly efficient in great altitudes. "Frank" had codinome; to the Allies and, it would be a great problem to be surpassed by the Americans if they were frabricados in a bigger number. The Japanese overloaded its Hayates, bringing to tona problems of operation and maintenance that would not appear with the use most moderate of the device. The drawing of this new hunting started in the beginning of 1942 and the first archetype flied in April of 1943, with its first tests going so well that the first lot of 83 aircraft for tests in service was ordered only four months later. It was a monoplane of wing low total constructed in metal(exceto its surfaces of control) e, had retractable landing gear. The Ki-84 possuía Hayate a radial engine Nakajima Ha-145 of 1.900 hp and was armed with two machine guns of 12,7 mm in the fuselage and two cannons of 20 mm in the wings. Tests of service in operational conditions had been enough convincing so that the Nakajima Ki-84 entered in wide production in the 1943 end. Its variants incluíam the armed Ki-84-Ib with four cannons of 20 mm, and the Ki-84-Ic with two cannons of 20 mm and others two of 30 mm. First the great operational envolvement of "Frank" it was in the battle of the Gulf of Leyte in 1944 ends, and of that moment until the end of the war in the Pacific the Ki-84 was joined in any place where it had intense action. He was used as hunting to attack and to repel the Americans and as bombing of diving to destroy the tracks of enemy landing insulares. In the attempt to obtain a composition in light league of the three variants of the Hayate, it appeared a new construction. But the first one entered in production, the Ki-84-II, that introduced tips of the wings and back fuselage in wood. Constructed in two sub-variants, these only differed between itself for having similar armament to the Ki-84-Ib or Ki-84-Ic. The others two aircraft of this category had been the three Ki-106 archetypes, total constructed in wood, and an only Ki-113, that a predetermined quota of steel used, for the same intention to save the metal. Another alone archetype was only constructed and flied, the experimental Ki-116, that was converted of Ki-84-Ia, being lighter and equipped with a radial engine Mitsubishi 1.500 Ha-33 of hp. When the production was locked up in August of 1945, a total of 3.514 Ki-84s Hayate had been delivers, constructed for Nakajima(3.416), Mansyu(95) and Tachikawa(3). An impressive fact carried through in very little time, resulted of one program that gave to the Hayate the most absolute priority. Without shade of doubts the Ki-84 was an incredible weapon, and a test of that Japanese aeronautical engineering was to the height of any adversary. The situation of the conflict when of its appearance already it was total favorable to the Allies, who exactly being in superior number incrivelmente, still respected the Nakajima Ki-84. Many times when it blunted in some viewfinder of American radar, the operator communicated to the pilots of Mustang and Corsair in air: they "Esqueçam, is a Frank".

had ki-84 no problems on altitude, japans would not make high-altitude inteceptors ki-102b, j2m, d4y-j, ki-46-iii etc. actually altitude performance of hayate was not satisfactory. engine is not ha-145. it is ha-45-11 (1800) for early types and ha-45-21 (1900) for late ones. i think this source is a bit more detailed and correct: http://www.csd.uwo.ca/~pettypi/elevon/baugher_other/ki-84.html
