  • CyberBug interface

    A close-up of the CyberBug's ground control software interface. The drone can fly for up to three and a half hours, depending on the payload, with a top speed of about 20 mph.

  • Global Hawk UAV

    One of the largest UAVs is the Global Hawk, which has a wingspan of 116 feet. (A Cessna 152 has a wingspan of just 34 feet, and a DC-10 has a wingspan of 155 feet.) The U.S. military used the Global Hawk during the invasion of Afghanistan. It can fly at altitudes up to 65,000 feet at about 400 mph with a range of 12,000 nautical miles. Surveillance images are relayed in near-real time through satellites or direct radio links. The 12th Reconnaissance Squadron pictured here is the home unit for the Global Hawk mission.

  • Long haul Hawk

    The Air Force's Global Hawk made aerospace history as the first UAV to fly without refueling 7,500 miles from Edwards Air Force Base, Calif., to Australia.
