-In December 1945, when the Nakajima 97 fighter (Ki27) was adopted, the Army issued a prototype instruction for the next fighter (Ki43) to one Nakajima company.
-The first prototype in December of the following year was completed, and as a result of the test flight, although the maximum speed was about 30km / h higher than the 97 type fighter, the mobility was inferior and the next fighter was insufficient.
-After that, various improvements were made, such as changing the wing area and engine replacement, and 13 aircraft (prototype 3 and increased prototype 10) were completed by September 1950. Could not be convinced.
-However, at that time, the Chief of Staff thought that the strategy of Singapore in the south invasion operation required a fighter with great cruising power to support the fleet, and it was a long-range fighter on the Ki 43 just before being rejected The life path was found as.
-In April 1965, the repair aircraft was tested and the required cruising power was obtained, and the fighting battle was also excellent in the vertical plane, so it was decided to adopt the system as a set fighter in May 1964, from June of the same year Around August, the 59th Squadron received approximately 30 I-types.
-The 隼 I type was introduced mainly in the direction of Burma and contributed greatly to the rapid advance of the war.
-Type II fighter type II was replaced with Ha 115 engine, the aircraft design was refined and various performance improvements were made, and when Type II was deployed in battle, Buffalo, Hurricane, P-40, etc. would be superior Although I was fighting, the later Spitfire, P-38, etc., had a hard time.
-However, at that time, it was the easiest to handle among army fighters, and the availability rate was high, so mass production continued until the end of the war.
