Stalin is quoted that "Quantity has a quality all its own". In some situations that may be true. I had some Air Force guy tell me that our aircraft can handle 10 enemy aircraft at one time. When I asked him what happens when nos. 11-15 show up I got a deer in the headlights reaction.
With the F-22, you can handle 10 or more, but realistically, you are talking 11 trained enemy pilots.
That is very, very expensive and hard for anyone to do, even the US.
With drones, the training becomes infinitely less expensive.
Support costs, however, could increase.
Recovering certain downed drowns may be required, for example.
