A full-scale model of Northrop Grumman's RQ-4 Global Hawk will be on static display at the Air Tattoo.
Global Hawk is an unmanned aerial vehicle (UAV) used by the United States Air Force and Navy as a surveillance aircraft and has just entered the test and evaluation phase with the German Air Force.
In role and operational design, the Global Hawk is similar to the Lockheed U-2, the venerable 1950s spy plane. It provides a broad overview and systematic target surveillance mthat can penetrate cloud-cover and sandstorms. It can survey as much as 40,000 square miles (103,600 square kilometers) of terrain a day.
In the RQ-4 name, the "R" is the Department of Defense designation for reconnaissance and "Q" means unmanned aircraft system. The "4" refers to the series of purpose-built remotely piloted aircraft systems.
