COLORADO SPRINGS, Colo., Nov. 13, 2012 /PRNewswire/ -- The Air Defense, Missile Warning, and Space Defense systems that support the missions of North American Aerospace Defense, U.S. Northern Command, and U.S. Strategic Command will continue to be sustained by Lockheed Martin [NYSE:LMT]. The U.S. Air Force Life Cycle Management Center (AFLCMC) awarded Lockheed Martin a contract to provide operations, maintenance, and sustainment of these missions under the Integrated Space Command and Control (ISC2) system. The contract consists of three one-year options, with a total potential value of $250 million.

"Lockheed Martin is honored to sustain these critical missions," said Cliff Spier, vice president of Command & Control Solutions for Lockheed Martin Information Systems & Global Solutions-Defense. "We'll work with AFLCMC to ensure that ISC2 continues to provide commanders with synchronized C2 operations that improve strategic and tactical coordination among our forces." By integrating mission critical networks between U.S. Northern Command, U.S. Strategic Command and North American Aerospace Defense, ISC2 provides geographically disparate commanders the ability to monitor and assess multi-mission threats concurrently. Under the sustainment contract, Lockheed Martin will support the Space, Air Defense and Missile Warning missions, ensuring that information and data is seamlessly shared between those and other C2 systems. The Air Defense and Missile Warning missions are part of the Integrated Tactical Warning Attack Assessment mission, which provides warning to the President if North America is under attack. The Space mission system is used to catalog space objects and perform conjunction assessments to provide manned space flight safety and protect other key space assets. Since 2000, Lockheed Martin has supported geographically diverse components of the ISC2 system worldwide. The system has personnel at Offutt Air Force Base, Peterson Air Force Base, Vandenberg Air Force Base, Cheyenne Mountain Air Force Station, and other locations.
