stealth fighter is that the enemy fighters cannot use radar guided AAM to lock on you. It doesn't really matter if the enemy can detect your existence using land based or even AWS based long wave radars, or passive radars, those radars cannot give precise position and guide missle to attack it. Without radar guided missle, the enemies cannot use BVR to attack F-22, and F-22 also have powerful countermeasure for laser and infrared guided missles. That why F-22 is the most powerful air superiority fighter.
