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.
The action of the Ho-103 was developed from the American M1919/M1921 Browning. It was badly suited for use in a synchronized mounting, reducing the fire rate from 900 to 400 RPM. The Type 1 machine gun (Ho-103/Ho-104) is distinct from the identically named Type 1 machine gun derived from the German MG 15.

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.
The Ho-103 is nose-mounted and synchronized in many Japanese aircraft, cutting the fire rate in half. The result is a machine gun that fires a weak cartridge with high drop and a short effective range at as little as half the fire rate of its contemporaries.
Usage in battles
- Due to the low velocity, it is often impractical to use the Ho-103 at anything other than close range
- The low damage output and (frequently) low fire rate means a sustained burst is generally required to disable a target.
- 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 12.7mm rounds consistently do more damage than 7.7mm.
- The unsynchronized rate of fire is high.
Cons:
- Low muzzle velocity.
- The available shells have comparatively weak payloads.
- Low synchronized fire rate.
History
Examine the history of the creation and combat usage of this weapon. If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article.
Media
An excellent addition to the article would be a video guide, as well as screenshots from the game and photos.
