Description

From the beginning of hostilities in China in 1937, the Japanese Navy had been the target of small but annoying bombing attacks by Chinese air forces. Feeling the need for a high-speed, quick-climbing interceptor to combat such raids, work began on what was to eventually become the Raiden ("Thunderbolt") in 1938. Slowed by priority work on the A6M Zero, Jiro Horikoshi's team at Mitsubishi eventually chose to employ the powerful 14-cylinder Mitsubishi Kasei 13 radial engine in the new plane despite concerns about it's large size and high fuel consumption. To combat the big powerplant's drag, it was decided to mount it deep within a long, tapered cowling, connecting the propeller via an extension shaft and incorporating a cooling fan. The first prototype flight finally took place in March of 1942, but problems with the engine and its cooling system, poor pilot visibility and sub-specification performance led to numerous modifications. These included replacement of the engine and extension shaft system with the more-powerful Kasei 23a, resulting in a shorter nose and improved visibility. Satisfied, the Navy ordered production of the Raiden Model 11 (J2M2) beginning in September 1943. Work also quickly began on the Model 21 (J2M3), which boosted armament from the two 7.7mm machine guns in the fuselage and two wing-mounted 20mm cannon of the Model 11 to four wing-mounted cannon, dropping the MGs completely. This was by far the most-produced model of the plane. Other minor variants included the turbo-supercharged Model 32 (J2M4) and larger-cockpit, supercharged Model 33 (J2M5). Total production of all Raiden variants totaled approximately 500 aircraft by war's end. In service, the Raiden -- code-named "Jack" by the Allies -- proved a fine aircraft and it was the preferred bomber-destoyer of IJN pilots late in the war, where it frequently faced incoming U.S. B-29s with some success. Nevertheless, confusion over its role in the Navy -- many advocated the faster Shiden in the interceptor role -- and persistent technical problems slowed its production to levels where its impact on the outcome of the conflict was limited. The Raiden's of the 302nd which were equipped with the angled guns had a gunsight installed in the center of the front windscreen, with the muzzle of the gun extending slightly from the left side of the fuselage. They were used with effect in the group's attacks on incoming American bombers during the latter's raids on Tokyo.
