The Raiden was created by engineer Jiro Horikoshi and his designers that has taken fee of the Zero Fighter. To reduce air resistance, had not been best suited to be utilized in a fighter. The Raiden had been designed by engineer Jiro Horikoshi and his designers that has taken fee of this Zero Fighter. To minimize atmosphere resistance, the propeller shaft regarding the engine had been made longer as well as the cowling had been made slenderer. To have greater cooling efficiency, the forced-cooling fan ended up being utilized. The body had been spindle-shaped along with its biggest area on 40percent of its general size. The wing load was because big as 145 kg/m? and, in due consideration of dogfights, Fowler flaps had been used. The retracting system and propeller pitch changing system of electric type had been used in host to those of hydraulic kind which had a bad reputation.
The 14-Shi Interceptor made its very first flight at Kasumigaura Airfield on twentieth March, 1942. As a result of different tests routes made thereafter, defects particularly insufficient power regarding the Kasei engine, bad vibration associated with extended propeller shaft and bad visibility were described. A production type which bettered presence by shortening the nose and remodelling the canopy and mounted the more powerful Kasei 23 engine loaded with the water-methanol injection system made its very first journey on 13th October, 1942. The manufacturing kind also developed numerous troubles into the motor as well as other parts, therefore was in December 1943 that the airplane ended up being accepted to be used underneath the title of Raiden Type 11 (J2M2). In the meantime, the Raiden Type 21 (J2M3), an anti-bomber fighter which had more powerful armament comprising four belt-fed 20mm device firearms, had been finished in October 1943 and today became the primary object of production. The production of the kind 21 totaled about 300.
The Raiden Type 21 very first saw action in the Battle of Mariana in September 1944. Afterwards, some were provided for the Philippines and Formosa and participated in actions, but the outcome wasn't as effective as the Japanese had anticipated. It was in air protection actions the mainland by the Raiden product of 302nd Air Group based on Atsugi that the Raiden exercised unique power to the entire and showed the absolute most brilliant activity. The Raiden product distinguished it self by shooting down a complete of approximately 300 enemy planes in the short period from end of 1944 toward end of this war. It owed much of its success towards the proven fact that it could easily obtain necessary material through the nearby Koza naval air arsenal which produced the Raiden, the geographical conditions that its base Atsugi ended up being situated nearby the length of B29 bombers intruding to the Kanto district, together with best consolidated air immune system and air control through radar network.
