5th generation tactics/thinking

I have some very valid questions concerning the F-22,F-35,T-50 and J-X.

even though some will disagree with me some web sites are claiming that 5th generation tactics will offer a paradigm shift in the way we fight. for instance:

-The publication second line of defense believes that in the future AWACS will have less relevance due to stealthy platforms carrying advanced AESA over hostile air space, all while data linked and sensor fused.

But the difference between a Hornet or a Viper and the Raptor isn’t just the way you turn or which way you move the jet or what is the best way to attack a particular problem. The difference is how you think. You work totally differently to garner situational awareness and make decisions; it’s all different in the F-22. With the F-22 and certainly it will be the case with the F-35, you’re operating at a level where you perform several functions of classic air battle management and that’s a whole different experience and a different kind of training.

SLD: When you’re in a classic tactical aircraft, basically somebody else is doing the battle management in an AWACS or CAOC or somewhere. With this aircraft, with the F-22 and certainly the F-35, you’re really moving from a classic air battle management approach and that’s got to be a whole different experience and require a different kind of training.

Lieutenant-Colonel Berke:It absolutely is. The irony is that when you talk about distributed battle management it is based on how the F-22 and F-35 provide for situational awareness. With an F-18 or F-16, you have federated sensor systems; the information is stovepiped and the pilot must fuse the information in his own mind.

-In light of these developments, will traditional tactics for merging totally change?

– Even with only short range IR missiles why would you ever approach an enemy aircraft from a head on merge and come with in radar range when you can exploit stealth?

– Why would you ever enter into radar range when you could approach to BVR from the rear sector or find another vector out of sensor view?

-All of these aircraft claim advanced sensor fusion. in what other ways will this cause a shift in tactics?

-And finally please explain in layman terms just what SLD means when they talk about 5th generation thinking.

I await thoughtful and brilliant answers.
