Isn't stealth pretty much defeated for the last 40 years? I recall reading that Soviet ground radars were perfectly capable of detecting US stealth planes, as well as there being a crash of a stealth plane which was then recovered by the enemies of US.
Stealth is not a boolean property. What you can do on the ground with giant arrays of huge antennas and/or supercomputers is way ahead of what can be done in a fighter plane, and that is way ahead of what can be done in the seeker of a small-diameter missile.
I think there's only been one stealth aircraft detected and shot down in history and that was because they got a fix on it when the bomb doors were open rendering it non stealthy. Stealth isn't perfect but it makes hitting the things pretty hard.
