7 The Lockheed-Martin High Altitude Airship The Lockheed Martin High Altitude Airship, an unmanned lighter-than-air vehicle, will operate above the jet stream in a quasi-geostationary position to deliver persistent stationkeeping as a telecommunications relay, a weather observer, or a surveillance platform. Lockheed Martin, Akron, received its first production contract for a lighter-than-air vehicle in Since that time, Lockheed Martin has built more than 300 airships and several thousand aerostats (an unmanned ground-tethered blimp). The Lockheed Martin Airdock, which is 1,175 feet long, 325 feet wide and 211 feet high, may serve as a final assembly facility.
