SBIRS propulsion module done

SUNNYVALE, Calif. -- Lockheed Martin completed the propulsion module for the fourth Space-Based Infrared System (SBIRS) Geosynchronous Earth Orbit (GEO-4) space vehicle and is now proceeding with satellite assembly, integration and test. SBIRS provides continuous early warning of ballistic missile launches and other tactical intelligence. Final assembly and test of the GEO-4 satellite's propulsion module occurred earlier this year at Lockheed Martin's Mississippi Space & Technology Center at Stennis Space Center. The propulsion module maneuvers the satellite during transfer orbit to its final location and conducts on-orbit repositioning maneuvers throughout its mission life. (Source: Lockheed Martin, 05/06/14)
