SUNNYVALE, Calif., April 14th, 2009 — Lockheed Martin [NYSE: LMT] has successfully completed thermal vacuum testing of the second Advanced Extremely High Frequency (EHF) military communications satellite, a major program milestone that proves spacecraft performance and functionality in a complete test-like-you-fly environment.
The U.S. Air Force’s Advanced EHF system will provide global, highly secure, protected, survivable communications for warfighters operating on ground, sea and air platforms.
Conducted between Jan. 26 and March 14 inside Lockheed Martin’s Dual Entry Large Thermal Altitude (DELTA) chamber, the successful test verified Advanced EHF spacecraft functionality and performance in a vacuum environment where the satellite was stressed at the extreme hot and cold temperatures it will experience in space throughout its 14-year design life.
