LOS ANGELES AIR FORCE BASE, Calif. —
The Space and Missile Systems Center’s next Space Based Infrared System satellite reached a major milestone on its the road to launch when Thermal Vacuum testing began on April 16 at Lockheed Martin’s production facility in Sunnyvale, Calif\. SBIRS uses infrared surveillance to provide missile warning for national defense. The system consists of a constellation of satellites in both Geosynchronous Earth Orbit and Highly Elliptical Orbit. The newest SBIRS satellites, GEO-5 and GEO-6, are based upon Lockheed Martin Space’s modernized LM 2100 spacecraft – an update that improves overall system resiliency to provide mission assurance to the warfighter.
