Yeah so some years back Iran managed to hack one of our stealth drones and make it crash land on an Iranian airstrip.
The big take away from this event is not the fact that the Iranians were able to hack one of our stealth drones.
The big take away is that the Iranians even knew it was there.
At this point, any adversary with the ability to shoot down these aircraft will also be capable of seeing through their stealth capability. As a consequence, we should abandon stealth technology in favor of high speed, high maneuverability, with a low cost, unmanned and disposable design with the expectation that losses will be massive.
