Description
The Ho-103 is a variant of the Japanese Type 1 short-recoil operated heavy machine gun. The design was based on the M1921 Browning and chambered for the Italian 12.7x81SR cartridge. Compared to contemporaries such as the M2 Browning, the Ho-103 weighed less but had significantly lower muzzle velocity and projectile mass.

General info
The Ho-103 is the variant of the Type 1 machine gun intended for fixed mounting. It is directly related to the Ho-104; the Ho-104 being intended for flexible mounting.

Comparison with analogues
The Ho-103 is one of the weakest aircraft HMGs in War Thunder.
Projectile mass (and thus explosive/incendiary payload) is lower than both the American .50 BMG and the German 13x64B cartridges. Muzzle velocity is slightly higher than the German MG 131, but over 100 m/s lower than the American M2. The low mass and low velocity reduce the effective range of the weapon and increase the necessary angle for bullet drop compensation.
Usage in battles
- Due to the low velocity, it is often impractical to use the Ho-103 at anything other than close range
- The typically low ammunition count of Japanese aircraft using the Ho-103 means that ammunition must be conserved judiciously.
- The Default and Tracer belts should not be used if possible. The lack of explosive incendiary bullets greatly reduces damage dealt.
Pros and cons
Pros:
- The weapon itself is fairly light
- The fired 12.7 mm rounds consistently do more damage than 7.7 mm
Cons:
- Low muzzle velocity
- The available shells have comparatively weak payloads
History
The Type 1 machine gun, more commonly known by the Ho-103 is a Japanese copy of the M2 Browning. However, despite the M2's design inspiration the ammunition was first supplied from Italy from their Breda-SAFAT da 12.7 mm machine guns before Japan began domestic production of ammo for the gun. The Japanese produced ammunition, roughly between the .50 BMG and the 13mm rounds from the German MG 131, gives the Ho-103 a slightly higher rate of fire of compared to the M2 Browning but at the cost of range and muzzle velocity. To compensate, the Ho-103 was mostly loaded with High-Explosive Incendiary ammunition. The Type 1 came in two varieties. The Ho-103 is primarily used to refer to the fixed mounted version while the Ho-104 is considered the flexible mounted variant.
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
