SBIRS delivered to Cape

The U.S. Air Force and Lockheed Martin have delivered the second Geosynchronous Earth Orbit (GEO-2) Space Based Infrared System (SBIRS) spacecraft to Cape Canaveral Air Force Station, Fla., where it will be prepared for a March liftoff aboard a United Launch Alliance Atlas V. Featuring a mix of satellites in geosynchronous orbit, the SBIRS program provides improved missile warning capabilities. The contracts include four HEO payloads, four GEO satellites, and ground assets to receive, process, and disseminate the infrared mission data. The team has also begun initial work on the fifth and sixth GEO satellites. Two HEO payloads and GEO-1 have already launched into orbit.
