The fact of the matter is, stealth technology means that an aircraft needs to be significantly closer to a radar for it to be detected compared to a normal aircraft. That also means it has to be closer still for a threat radar to develop a weapons quality track. Theres not really any known radar technology that can mitigate this, it’s basic physics. It’s much easier to see an object on radar that returns orders of magnitude more energy to the radar.
Stealth does not a limited utility. In fact it’s rapidly going to become an absolute bare minimum for any tactical aircraft.
