Hehe, this might catch fire, but the fact remains that wherever the USSR hardware on wings met western hardware on wings, the USSR hardware was the underdog, - statistically. I am talking of any significant conflicts, like Finland vs USSR, LW vs USSR, Korea, Nam, Syria. All I left is smaller stuff.
Now, lot of it was tactics, I know. Especially WW2 and Korea, where you basically had very well matched aircraft with a difference in performance/maneuverability that would even be with the USSR. But, anyway, I could not resist to bring up the point. USSR aircraft in combat have in most conflicts been shot down in more numbers than any....
