[11-21-07 – Satellite Today] Lockheed Martin has delivered the core propulsion module for the Advanced Extremely High Frequency (AEHF) system, the company announced Nov. 20.
    AEHF, a military communications system that will provide secure, protected, survivable communications for warfighters serving under the U.S. Department of Defense, is essential for maneuvering the satellite during transfer orbit to its final location as well as conducting on-orbit repositioning maneuvers throughout its mission life.
     The delivery allows Lockheed Martin Space Systems, the AEHF prime contractor, and Northrop Grumman Space Technology, the payload supplier, to prepare for the spacecraft and payload mate planned for mid-2008, followed by environmental and acceptance testing of the completed satellite. The launch of the satellite is scheduled for 2009.
