Description
It was the standard hand-held machine gun in multi-place IJN aircraft during the most part of the Pacific War. It proved to be seriously inadequate. Aircraft produced in the later part of the conflict often were equipped with weapons such as Type 1 and Type 2 machine guns or Type 99 cannon.
Essentially a copy of the shroudless post-World War I aircraft-mounted version of the British Lewis gun, the Type 92 was fed with a 97-round drum magazine and used on a flexible mount. It was chambered in a Japanese copy of the .303 British cartridge. The main external difference between the two models was the trigger guard, and cooling fins around the barrel and gas piston tube. Neither the post-World War I British aircraft Lewis nor the Japanese copy featured the distinctive thick barrel shroud of the original gun (although ground-based versions generally retained it). It was removed as it was found that the airflow past the aircraft was sufficient for cooling the barrel and eliminating the shroud reduced the mass.
