ANDERSEN AIR FORCE BASE, Guam, Sept. 21 (UPI) -- Northrop Grumman's Global Hawk unmanned aerial vehicle has been permanently based in the Pacific region by the U.S. Air Force.
The high-altitude aircraft, designated AF-20, landed at its home station in Guam earlier this month after an 18-hour flight from Beale Air Force Base in California, the company said.
