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.

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 as the Ho-103 or Ho-104, 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 machine guns before Japan began domestic production of ammo for the gun. The Japanese-produced ammunition, roughly between the .50 BMG and the 13 mm rounds from the German MG 131, gives the Ho-103 a slightly higher rate of fire 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.
