Sorry, you're wrong. The Spit Vc to Vb had nothing to do with the Vc being rare,
Jumping the gun there, mate. I never said it was. I said it was more representative... It was one of the examples of how they are moving to a more representative planeset, and since the only major SpitV matchup of EPIC proportions is against the Bf109F over the English Channel, it made sense to pair those 2 planes up properly.
I'm saying they're trying to do something other than just throw in random rarely-used guns, guns that never saw the light of day, or test kits, etc. I'm saying they're doing the responsible thing. With that in mind, the responsible thing IMO ought to be "remove the 20mm from the B-29 tail."
Ack Ack, I thought there was also a large component of the guns being unreliable, jamming, or just not being desired by the crews.
Beef, 5pointoh, "field mods" are different from general changes made at the depot level per orders from above. I think they make a difference for HTC. Those 2 changes weren't just some renegade ground crew sticking guns on planes at random.
Also, Beef: The 20mm is Hispano. It's about as close to 50cal trajectory as you can get, especially when firing rearward at 350+mph...
