Oh I see what you mean now Grun... sorry about that.
They fly for the USAAF/VVS/etc, correct. But they aren't built by them.
I just leave out Air Force affiliations to the planes because it doesn't have any bearing on what it fought for just who it fought for. (WWII LuftWaffe can easily be associated with fighting for Nazis, which is why I leave off air force designations and stick to the country it fought for)
