RQ-4  

Definition

  • A high-altitude, remotely-piloted, surveillance aircraft. It was initially designed by Ryan Aeronautical (now part of Northrop Grumman), and known as Tier II+ during development. The RQ-4 provides a broad overview and systematic surveillance using high-resolution synthetic aperture radar (SAR) and electro-optical/infrared (EO/IR) sensors with long loiter times over target areas. It can survey as much as 40,000 square miles (100,000 km2) of terrain per day, an area the size of South Korea or Iceland. The Global Hawk is operated by the United States Air Force (USAF). It is used as a High-Altitude Long Endurance platform[2] covering the spectrum of intelligence collection capability to support forces in worldwide military operations. According to the USAF, the superior surveillance capabilities of the aircraft allow more precise weapons targeting and better protection of friendly forces. (en)
