The Northrop Grumman RQ-4 Global Hawk is an American unmanned surveillance and reconnaissance aircraft that first flew in 1998, establishing high-altitude persistence reconnaissance as practical doctrine. With a 39.9-meter wingspan, single engine, and 629 kilometers per hour maximum speed, it provides comprehensive area surveillance from extreme altitude. The extended endurance allows extended observation of continental and oceanic areas from distant bases. This sophisticated platform revolutionized intelligence collection, establishing template for contemporary unmanned reconnaissance doctrine.
