 The '''Type 1 12.7 mm machine gun''', more commonly known as the '''Ho-103''' and '''Ho-104''', is a Japanese copy of the [[M2 Browning (12.7 mm)|AN/M2 Browning]] (Colt MG53-2), but redesigned for the the Italian ''12.7×81mmSR Breda'' cartridge.
-The history of the Type 1 aircraft machine gun starts in 1937 when the Imperial Japanese Army Air Service (IJAAS) bought Italian made Fiat BR.20 bombers (designated ''Type 1 bomber'' in Japanese service) armed with [[Breda-SAFAT (12.7 mm)|12.7 mm Breda-SAFAT]] guns chambered for the 12.7×81mmSR Breda cartridge. This was the first proper heavy machine gun in IJAAS service, leading to Japan cloning the design as the ''Ho-102''. However, after getting their hands on the more modern "Colt MG52-2" (1930s M2 Browning for aircraft use, designated .50 AN/M2 Basic aircraft machine gun in US-service), japan decided to instead clone its design and rework it for the already in use Italian cartridge as the ''Ho-103''. As the Italian "12.7×81mmSR Breda" cartridge is shorter and lighter than the "12.7×99mm Browning" cartridge used in the original Colt MG53-2 design, the Ho-103 design achieves a slightly higher rate of fire compared to its progenitor, as the bolt needs less power and travel time to extract and chamber ammunition, but at the cost of range and muzzle velocity due to the smaller propellant charge. To compensate, the Ho-103 was mostly loaded with High-Explosive Incendiary ammunition.

-The Ho-103 was intended as fixed armament, however it could be mounted in a flexible mount as defencive armament. In this configuration it is often incorrectly called the "[[Ho-104 (12.7 mm)|Ho-104]]", which was a different 12.7 mm flexible machine gun, developed from the fixed "Ho-101" 12.7 mm machine gun, a derivative of the 7.7 mm Type 89 machine gun reenginered for the 12.7×81mmSR Breda" cartridge.
