A large calibre weapon mounted on an aircraft, the 75 mm can deliver a good amount of fire onto target if the plane is flown right for the weapon system to be utilised. The user must be experienced in its usage as its mount design on an aircraft as well as its rather slow rate of fire mean that a user will have one, or maybe two, shot onto target before the plane passes over.

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

The cannon is hard to aim, so you should try to only go for ground targets only. It is possible to destroy other planes with it, but very hard. One other thing to keep in mind is that you have very little ammo, always watch the ammo count!

Pros and cons

Summarise and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.

Pros:

  • Great damage
  • Pretty short reload

Cons:

  • Hard to aim
  • Only 13 ammo

History

From June 1944, only 25 examples of the Hs 129 B-3 arrived at frontline units before the production line was shut down in September and a small number were reportedly also created by converting B-2 aircraft. In the field the B-3 proved effective, but its small numbers had little to no real effect on the war effort.

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
