Lockheed Martin builds missile warning system

The U.S. Air Force chose a Lockheed Martin-lead industry team to develop the satellite portion of the Space-Based Infrared System, better known as SBIRS, a missile-warning and tracking system intended to detect ballistic missile attacks on the U.S. or on its deployed forces or allies. SBIRS is to replace the aging Defense Support Program satellites and ground stations. Lockheed Martin Missiles & Space in Sunnyvale, Calif., is the prime contractor. Aerojet of Azuza, Calif., and Northrop Grumman of Bethpage, N.Y., supply the primary infrared sensor payload. - J.K.
