AeroVironment (AV), a world leader in the development of unmanned High-Altitude Long-Endurance (HALE) aircraft, has successfully completed the world’s first liquid hydrogen powered Unmanned Aerial Vehicle (UAV) flight tests.

The fifty-foot wingspan prototype aircraft accomplished a major milestone in AV’s Global Observer HALE system development. The Global Observer prototype demonstrates the practicality and operational robustness of the enabling technologies and concept of operations for the Global Observer system.

AeroVironment’s Global Observer HALE platform will be able to operate at 65,000 feet for over a week with a flexible payload-carrying capacity of up to 1,000 pounds. Using only two aircraft in rotation, with one Global Observer replacing the other on station once per week, this capability will provide seamless communication relay and remote sensing systems at breakthrough affordability.
