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!

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.
