I think the biggest problem w/ stealth is the inability to carry lots of weapons. I think the JSF and the F22 should atleast have the option to have external hardpoints. I wonder if they could coat bombs/missiles with Radar Absorbent Material (or RAM).
i think they will have the options for the pylons, they will be used for stealth at the beginning, taking out the sam sites, then when air superiority is established they can mount bombs and stuff onto the pylons and serve as multi-role aircraft ive heard. no need for stealth if there's nothing left to shoot you down.
