The Global Hawk is controlled via satellite.
It flew missions that went from Ed- wards AFB and back nonstop. Basically, they come into the fight at a high mach # using military thrust power, fire their AMRAAMS, and no one ever sees them or paints with radar. There is practically no radio chatter because all the guys in the flight are tied together electronically and can see who is targeting who, and they have AWACS (Airborne Early Warning and Control Systems) direct input, as well as 360 situational awareness from that and other sensors.
The enemy had a definite morale problem before it was all over. It is to air superiority what the jet engine was to aviation. It can taxi out, take off, fly a mission, return, land and taxi back on its own. There are no blackouts, pilot fatigue, relief tubes, ejection seats, and best of all, no dead pilots, and no POWs…
