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.
