According to various sources the number of Russian airframes lost range from 105 (Oryx, Dutch open-source intelligence project) to 672 (Ukraine). U.S. General Christopher Cavoli (former NATO Commander) stated that Russia had lost approximately 10% of it's airframes. Assuming he meant of all types across the entire Russian Air Force and using 2022 numbers that's about 426 aircraft. I'd venture the number is pretty close to what Gen. Cavoli stated; probably a little lower.
I don’t deny they’ve a few dozen helicopters and a few jets, but that’s what the silly claim was that I was referring to said.
