Just thought I'd post this photo that someone sent me of a Global Hawk UAV that returned from Iraq recently. It flew back under its own power... That's Iraq to Edwards Air Force Base in California non stop.
Notice the mission paintings on the fuselage. This UAV has flown over 250 missions. On really long missions the Global Hawk can stay up for almost 2 days at altitudes above 60,ooo feet. It is controlled through satellite communication. The Global Hawk can taxi, take off, fly a mission, return, land and put itself back in the hanger without a pilot inside.
When the Global Hawk attacks a target, it flies in at very high speed and fires AMRAAMS and other homing munitions... and is gone without ever being seen.
And for those who thought India has net-centric capability, this UAV shows what net-centric really means. It has direct AWACS and satellite input and, therefore, 360 degree situational awareness. When it is assigned to strike a target, everything this is needed --- maps, target recognition, weaponry data, etc --- is fed to it AUTOMATICALLY from the assigned controller.
