The RQ-4 Global Hawk unmanned aircraft system (UAS) is the premier provider of persistent intelligence, surveillance and reconnaissance information. Able to fly at high altitudes for greater than 30 hours, Global Hawk is designed to gather near-real-time, high-resolution imagery of large areas of land in all types of weather – day or night. Beyond intelligence collection a portion of the Global Hawk fleet has supported air and ground users with communications relay support. The EQ-4B Global Hawk previously carried the Battlefield Airborne Communications Node (BACN) payload providing life-saving support to warfighters. Global Hawk has amassed more than 320,000 flight hours with missions flown in support of military operations in Iraq, Afghanistan, North Africa, and the greater Asia-Pacific region. The system provides an affordable and flexible platform for multiple sensor payloads to be used together, delivering mission-critical information to various users around the world. In active operation with the U.S. Air Force since 2001, Global Hawk sees potential threats to allow commanders to gain greater understanding of an area of interest. These same intelligence-gathering capabilities also allow civil authorities greater ability to respond to natural disasters, conduct search-and-rescue operations and gather weather and atmospheric data to help forecasters predict the paths of storms.
