Global Observer UAS achieves historic first hydrogen-powered flight

AeroVironment, Inc.(AV) today announced that the Global Observer unmanned aircraft system has successfully completed its historic first flight powered by the aircraft's hydrogen-fueled propulsion system at Edwards Air Force Base (EAFB) in California. This milestone marks the beginning of high altitude, long endurance flight testing for the demonstration and operational utility phase of the Joint Capability Technology Demonstration (JCTD) program.

"Global Observer has moved quickly from development and testing toward demonstrating mission-ready, affordable persistence," said Tim Conver, AV chairman and chief executive officer. "Similar to a satellite, Global Observer is the first system designed to provide a 24/7/365 unblinking eye and continuous communications link over any location on the earth's surface for as long as needed. The joint AV and US government team developed Global Observer to meet today's urgent requirements for persistence and to enable the development of much more cost-effective solutions for the future. The speed with which we have achieved this milestone reflects the benefits of an effective government-industry partnership."

Because of its extreme endurance and range, Global Observer can be based out-of-theater, which will further reduce operating costs and local air traffic congestion while significantly reducing risk to operational personnel. AV plans to make Global Observer systems available for procurement and for operation as a turnkey service to provide communications and remote imaging in a manner similar to satellite services, but at a much lower cost.

The hydrogen-powered flight lasted for four hours and reached an altitude of 5,000 feet above sea level over the United States Air Force Flight Test Center at EAFB. This first flight follows the successful battery-powered flight test phase of the demonstration program that took place during the months of August and September.

The flight test team will now systematically expand the altitude and duration of test flights to validate the aircraft's high-altitude, long endurance performance. These flights will include the Air Force's Joint Aerial Layer Network (JALN) Tactical Communications Suite (TCS) payload. The JALN TCS provides persistent, IP-based aerial communications infrastructure that extends communications from a Global Observer aircraft positioned at 65,000 feet above sea level over a wide area. The joint operational utility of the Global Observer system will also be assessed during this flight test series for future US Government, civil, and military uses.
