In june 1941, there were twice as many mig3 in service as the yak1.
Compare the performance of the mig3, yak1, and lagg1 and produced by june 1941 and you find that the mig3 is pretty good in comparison and far better at high altitude.
WWII was being fought long before pearl harbor.....ask the finns who ran up huge scores shooting down russian planes.
Have to remember than late war main is not the only arena in aces high.
