Thanks for the info on the Fw190A-6.
I think you guys are getting too granular though.
I was thinking of aircraft needed to fill gaps in the timeline.
For example, we have no Bf109 to represent the time between our early Bf109G-6 and the high performing Bf109G-10. That is why the Bf109G-14 would make a great addition.
In the same vein, the Spitfire LF.Mk IX would give us the mainstay fighter of the RAF for 1943 and 1944.
These aircraft both fill gaps in the timeline. Gaps in which the Bf109G-6 and Spitfire F.Mk IX that we have were not the mainstay fighters, but are forced to be in AH setups.
Unless I am gravely mistaken, the Fw190A-6 never replaced the Fw190A-5, but rather served along side it. Thus that time gap is adequately represented by the Fw190A-5. We do not need the Fw190A-6 any more than we need the Spitfire Mk Vc, even though it could be said to close a two Hispano gap.
The same is true of the Bf109E-7. While neat and nice, it doesn't really fill a time gap because it served along side the Bf109E-4. For the same reason the Spitfire Mk IIa isn't needed.
A needed Fw190 is an early version like an Fw190A-1 or Fw190A-2 and a fighter (not bomber killer or Jabo) that is between the Fw190A-5 and Fw190D-9.
