Code-named "Jack" by the Allies, this single-engine, land-based fighter was used by the Imperial Japanese Navy Air Service in World War II. Jiro Horikoshi, creator of the A6M Zero, also designed the J2M. Equipment included a Mitsubishi MK4R-A Kasei 23a engine, two wing-mounted 20mm Type 99 Model II cannon, and two wing-mounted 20mm Type 99 Model I cannon. Raiden made its combat debut in June 1944 during the Battle of the Philippine Sea. A surviving J2M is displayed in Chino, California, at the Planes of Fame Museum.
