If China’s Stealth Fighter Is So Good, Why Is Beijing Still Buying Russian Warplanes?
War Is Boring

Fact is, no one knows how good any of these planes are, not even the F-22. A great deal of the quality of the latest fighters comes from sensors and avionics. Kinetic performance is less important. You can have a plane that has ZERO stealth characteristic and if it can still see and kill its opponent at a longer range then vice versa it will still rule. That ability may come from outside the fighter and instead in the overall combat system in which it operates. Hopefully we never find out who has the best.
