Global Hawk Hits 5K: 
An Air Force’s RQ-4 Global Hawk unmanned aerial vehicle recently surpassed the 5,000 combat flying hour mark while flying a mission in the global war on terror, says Northrop Grumman. The UAV began flying combat missions in 2001, accumulating more than 233 missions to its credit. A single RQ-4 has flown 157 of those sorties.
There is a new entrant in the highly competitive field of collaborative combat aircraft—semi-autonomous drones meant to fly alongside manned combat aircraft. Northrop Grumman unveiled its new Project Talon aircraft to a small group of reporters at the facilities of its subsidiary Scaled Composites.
