The High Altitude Airship is a next-generation military blimp. Lockheed Martin describes it as an untethered, unmanned lighter-than-air vehicle that operates above the jet stream in a geostationary position. Its potential functions include surveillance, telecommunications relay and weather observance. Lockheed Martin and the U.S. Army launched this prototype in July 2011, demonstrating its communications capabilities, solar array electricity generation, and remote piloting and control.
