The RQ-4 Global Hawk is an American strategic reconnaissance unmanned aerial vehicle. Developed by the American company Teledyne Ryan Aeronautical, a subsidiary of Northrop Grumman.
The fuselage of the RQ-4 Global Hawk is made of aluminum alloys. The wing is made entirely of carbon fiber composite material. The V-shaped tail is also made of composite materials.
The Global Hawk is equipped with the HISAR (Hughes Integrated Surveillance & Reconnaissance) integrated surveillance and reconnaissance system. The complex includes a SAR/MTI radar, as well as optical and infrared sensors.
All three subsystems can work simultaneously, and their data is processed by a single processor. Digital data can be transmitted to earth in real time within a line of sight or via a satellite channel at speeds of up to 50 Mbit/s.
RQ-4D UAV and its maintenance infrastructure are located at all US and NATO military bases.
