Information About

Mitsubishi J2m




The Mitsubishi J2M "Raiden" (雷電, "Thunderbolt") was a single-engine, land-based Fighter Aircraft used by the Imperial Japanese Navy in World War II . The Allied codename was "Jack".

The J2M was designed by Jiro Horikoshi , creator of the Mitsubishi A6M "Zero" . It was strictly a 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 maneuvrability. The J2M was a sleek but stubby craft with its oversized Mitsubishi Kasei engine buried behing a long cowling, cooled by an intake fan and connected to the propeller with a long extension shaft. Pilot visibility was poor.

A surviving J2M is on display at the Planes of Fame museum in Chino, California.

  • Loaded: 3,482 kg (7,676 lb)

  • Maximum takeoff: kg ( lb)

  • Powerplant: 1x Mitsubishi MK4 U-A 14-cylinder radial, 1,358 kW (1,820 hp)



Performance

  • Maximum speed: 615 km/h (382 mph)

  • Maximum speed: 698 km/h(Test/USA・AirForce))

  • Range: 555 km (345 miles)

  • Service ceiling: m ( ft)

  • Rate of climb: 925 m/min (3,838 ft/min). 6,000 m (19,685 ft) / 6 min 20 sec.

  • Wing loading: 174 kg/m&2 (35 lb/ft&2)

  • Power/Mass: 0.39 kW/kg (0.24 hp/lb)



Armament

  • 2x 20 mm Type 99-II Mk 4 Cannon in each wing. Ammo: 200 rpg approx. A 3rd oblique mounted cannon in some interceptors could fire upward as it passed underneath a bomber.

  • The Type 99-I pair of the J2M3 mix were dropped from the J2M5. Now all 4 wing cannon were harmonized in trajectory and ballistics performance like the Shiden fighters but with more ammo than they had (200 vs 70-125 rpg).


The 20x101 cartridge gave the 128 g HE (6-8 %) projectile an effective range of 1,000 m and a muzzle velocity of 750 m/s. The rate of fire was only 500 rpm each however (down from 520 rpm for the 99-I Mk 4 which only had a muzzle velocity of 600 m/s and a range of 730 m with it's 20x72 cartridge).
