If they are going to use stealth in dogfighting combat, they are going
to have to to toss any vestige of the visual ID of the enemy concept,
because if you can see and identify him, he can see and identify you,
unless you are using some sort of magnified visual ID system, which
neither the F-22 or F-35 seem to be equipped with.
This also leaves one wondering about putting close range AAM's like
Sidewinders on stealth aircraft, because to get within range to use
them, you are also inside the visual range of your opponent.
That's sort of the point...it's not useful at all in a dogfight, and has
it's limitations in avoiding an airborne intercept altogether. Not to
mention that in the context of an integrated defense system you don't
necessarily even "need" a radar to find who you're looking for. It's
sort of middle-aged to old tech now that the cat is out of the bag.
...oh yeah - radar's highly over-rated, too.
