Most of the modern American aircraft have a level of communication integration that the Russian planes do not have.

More advanced radars, and more information live and in real time compared to the Russians. In fact I believe the mantra of the current air force and planes are, if you see your enemy plane you are already dead.

Why? The idea is to use stealth and advanced missiles to pick off competition from a distance. What once was a book/theoretical exercise where one could host a B-52 from tens of miles away and shoot massive amounts of air missles with the guidance of stealth, is now a reality.
