Northrop Grumman Corporation (NYSE:NOC) has completed integrating all electronic units of the payload module for the third Advanced Extremely High Frequency (EHF) military communications satellite. The company is under contract to provide three communications payloads to Advanced EHF prime contractor Lockheed Martin (NYSE:LMT), Sunnyvale, California. The Advanced EHF system will provide global, highly secure, protected, survivable communications for warfighters operating on ground, sea and air platforms. Integrated with Lockheed Martin's A2100 space vehicle structure, the payload module consists of the complete set of radio frequency, processing, routing and control hardware and software that perform the satellite's protected communications function. The equipment includes approximately 20 electronics units and approximately 500,000 lines of software code.

Advanced EHF is the successor to the current Milstar system, the only protected satellite communications system operating in geosynchronous orbit. It alone provides our nation's warfighters and leaders with assured, global communications in the face of jamming and other threats. One AEHF Satellite will provide greater total capacity than the entire Milstar constellation. Individual user data rates will be five times better. The higher data rates will permit transmission of tactical military communication such as real-time video, battlefield maps and targeting data. In addition to its critical tactical mission, AEHF will also provide the survivable, assured communications to National Command Authority in all levels of conflict.
