all flight and ISR instructions– No man-in-the-loop required– In-flight changes made by
ground operators
• Longer wing span than a Boeing 737
• Operates for over 28 hours without refueling
• Operates at altitudes up to 65,000 feet

Operation Iraqi Freedom• Flew only 3% of air breathing Imagery Intelligencemissions and 5% of hi-altitude reconnaissance sorties yet accounted for 55% of the Time Sensitive Targetsgenerated to kill air defense equipment.
• Over 15 combat missions (as of 23 April 03)
• Over 350 combat flight hours • Over 4,800 Images taken during Operation Southern Watch
/ Operation Iraqi Freedom (as of 23 April 03)• Electro-Optic (EO) – 1,296
“… Global Hawk unmanned aerial vehicles have been proven to be invaluable in providing long dwell surveillance, tracking, positive identification, and collateral and strike damage assessment. … Global Hawk, for example, flew sorties approaching 30 hours in duration and imaged over 600 targets during a single mission over Afghanistan.”
