I always take exception and the use of production nummbers to argue the inclushion of aircraft, it is not realy a good point of departure for an arguement like "it should be added since more were made" I prefer the point that it was revelent because it was the apponit of this plane in this theater, and represented the best of what that country had at the time frame ou are looking at. Take the case of the Ki 84, certainly many many more P 51's were made but it was one of the bet fighters of the war and Certainly one of the most important Japanese Fighters of the war, and withen that time fram their are other clases of planes that were very important and capable planes. Like the Ki 67 one of the best in it's type out of any of the countries in the war and certainly a very important plane for Japan. Now bearing this in mind and looking at what we have now, and not wanting to be reduntant in terms of capabalities( at leaset in term's of everything but fighters), lets consider the above list...
Yak-1 *, A good choice.
Polikarpov I-16 * An excelent Choice A very important plane for the U.S.S.R. and a great plane for AH, very capable and verstile.
P-39 * A popular plane but the above plane are neaded more I think, and we have good Russian plane from this time frame now.
He-111 * A redundant adation we have the JU 88 a much better plane, Any new German Bomber should be late war imo, He 177.
Tupolev SB-2 or Ilyushin IL-4* Il-4 or Pe-2 would be Nice,TU-4 would be Best imo.
Ju-87 * A popular plane and a capable dive bomber.
I realy feal the Italians nead a new toy, and their are at least 3 planes that would be great adations, The Cant Z 1007, MC 200, or a RE 2000 series plane, not to mention a G 55.
The Japanese plane set is so mismatched time wise it is extreamly dificult to creat a well balenced CT set up with it, their are a number of Great late and early war planes that could be included, the Grace, the Frank, the Randy(late war), the Kate, Oscar,Nick, Ki 44(mid to early).
The Russians have some good planes no doubt, but they too are sufering from a mismatvhed plane set and sorely nead a buff, the TU-4 is the way to go here I feal.
The US and Brition and Germany are doing prety good I think, and CV strike plane for England would be nice, and a Stuka or a He 177 for Germany (or a Me 163:) ), would be cool to, the USA well I just cant say they realy nead anything.
A New GV would be nice as well.
