Oh, i thought the theatre headline was "The planes we truly need most". not "What planes are still missing?".
Imho some russian planes are badly missing, like the I-16, Ya1/7, Yak3, Mig3, Lagg3, but also the P39 and Ki-43 was pretty important planes in WWII.
Regarding bombers, of course the He111, Blenheim and Pe-2, but also the Ju87G(allieds already have their tank hunter).
Out of this i miss the early VVS fighters( i count the P39 to them) most!!
