RQ-4 Global Hawk UAV from Northrop Grumman.
Habitat: High above Iraq, Afghanistan and Pakistan—or anywhere else the U.S. Central Command wants to keep under watch.
Behavior: Soaring at 65,000 feet with an endurance of 36 hours, the Global Hawk can keep watch over 40,000 nautical square miles per mission. Carrying a full suite of electro-optical, infrared and synthetic aperture radar sensors, it can operate day and night in all weather conditions. The larger variation has a 130-foot wingspan.
Notable Feature: The fact that it can take off and land autonomously greatly reduces the potential for crashes, which have handicapped the Predator and Reaper.
