Mitsubishi J2M
The Mitsubishi J2M ''Raiden'' (雷電, "Thunderbolt") was a single-engined land-based fighter aircraft used by the Imperial Japanese Navy Air Service in World War II. The Allied reporting name was "Jack".
==Design and development==
The J2M was designed by Jiro Horikoshi, creator of the A6M Zero, to meet the 14-Shi (14th year of the Showa reign, or 1939) official specification. It was to be a strictly local-defense interceptor, intended to counter the threat of high-altitude bomber raids, and thus relied on speed, climb performance, and armament at the expense of manoeuvrability. The J2M was a sleek, but stubby craft with its over-sized Mitsubishi Kasei engine buried behind a long cowling, cooled by an intake fan and connected to the propeller with an extension shaft.
Teething development problems stemming from the Kasei engine cooling system, and the main undercarriage members led to a slowdown in production.〔Air Enthusiast, 1971. p 68〕 A continual set of modifications resulted in new variants being introduced with the ultimate high-altitude variant, the J2M4 Model 34 flying for the first time in August 1944. It had a 1,420 hp Kasei 23c engine equipped with a turbo supercharger (mounted in the side of the fuselage just behind the engine) that allowed the rated power to be maintained up to Two upward-aimed, oblique-firing (aimed at seventy degrees) 20 mm cannons, mounted in the German ''Schräge Musik'' style, were fitted behind the cockpit with the four wing cannons retained. Unresolved difficulties with the turbo supercharger caused the project to be terminated after only two experimental J2M4s were built.
