ut do you have a source? It appears like Ukrainian AF wasn't that active. My point is superpowers can employ cruise or ballistic missiles to take out aerial defense systems in rapid fashion and even regional powers cannot counter that. Who knows what kind of jamming/electronic warfare techniques employed too. It seems to come down to offensive power. Best defense is offense indeed. Which is why nation's with high missile capabilities or air force capabilities are able to assert their will. Except potentially against superpowers.
