Yaks? 30.000 out of memory. The Il-2 and the La series also had enormous production numbers.
Spitfire 20.000, Hurricane some 13.000, 109 some 35.000 with the post war models (avia and hispano).
The USSR sheer numbers are funny, for AFAIK in only one year is the air more draining on the LW on the eastern front than the western/southern one, - 1943. LOL, now I'll have to find that source again...
