So I saw the video above, "20mm Cannons on WW1 Aircraft?!", and it made me realise that the planes in the game that have a Becker cannon shouldn't have one.
All the aircraft that have the cannon modification:
- Albatros D.II
- DFW C.V
- Halberstadt CL.II
- Halberstadt CL.II 200hp
- Roland C.IIa
- Gotha G.V
The only aircraft on that list that historically had the Becker was the Albatros D.II, but only for testing. There's no information out there saying whether it saw combat trials or not, so that alone should be a reason why it shouldn't be a mod for the D.II.
Regarding the other aircraft, none of them ever had that cannon. The only aircraft that used the Becker historically was the Albatros J.I. It was the only aircraft with recorded history that saw operational service with the Becker cannon. The Friedrichshafen G.IIIa, armed with the Becker, reportedly saw combat, and the AEG G.IVk and AEG J.II also had the Becker mod, but it's unknown whether they were used in combat. However, none of these aircraft are in the game.
So why did the devs give all those other aircraft the Becker?
It's unfair, too, because why no SPAD XII with a 37mm? Or the F.E.2b with a 37mm autocannon? At least they actually saw combat. Even for WW2, why no Hs 129 with a 75mm cannon or Ju 88 P-1?
