New LM-Built Missile Warning Satellite Progressing in Critical Test Phase

(Sunnyvale, Calif., March 19, 2008) -- Lockheed Martin [NYSE: LMT] announced today that the first Space-Based Infrared System (SBIRS) geosynchronous orbit (GEO-1) spacecraft is progressing through a series of key tests that will demonstrate the integrated satellite's readiness to enter the critical environmental test phase in preparation for launch in late 2009.

SBIRS is designed to provide early warning of missile launches, and simultaneously support other missions including missile defense, technical intelligence and battlespace characterization.

The test phase, known as Baseline Integrated System Test (BIST), is conducted at Lockheed Martin's Space Systems facilities in Sunnyvale, Calif. and is designed to characterize the overall performance of the GEO-1 satellite and establish a performance baseline prior to entering environmental testing.

The first phase of BIST, which included the GEO-1 spacecraft in an expanded configuration, was completed on Jan. 23, 2008. Following the successful test, the team assembled the satellite into the flight configuration, including the GEO-1 bus and payload and other critical subsystems. A comprehensive test of the integrated satellite is now underway.

Upon the completion of BIST in May, the team will integrate the satellite's solar arrays, deployable light shade, and thermal blankets and then prepare for acoustic and pyroshock testing where the integrated spacecraft will be subjected to the maximum sound and vibration levels expected during launch into orbit.

Prior to the start of environmental testing, the team will also conduct a major test to validate that the SBIRS ground components and the GEO satellite can work together during launch and on-orbit operation.

"Our steady progress in this critical integrated satellite test phase reflects the entire team's hard work and dedication to operational excellence on this vital national security program," said Jeff Smith, Lockheed Martin's SBIRS vice president and GEO-1 program manager. "This first-of-its-kind satellite will provide unprecedented new capabilities for our warfighters and we look forward to achieving mission success for our customer."
