Lockheed Martin to continue sustainment of defense systems COLORADO SPRINGS, Nov. 13 (UPI) -- A new U.S. Air Force contract to Lockheed Martin will continue company operations, maintenance and sustainment for vital U.S. air defense systems and commands. The sustainment contract in support of the Integrated Space Command and Control system was issued by the U.S. Air Force Life Cycle Management Center and consists of three one-year options with a potential total value of $250 million. Lockheed said that under the award, it will continue to serve the needs of support the North American Aerospace Defense, U.S. Northern Command, and U.S. Strategic Command by modernized the Air Force's air defense, missile warning and space command and control information technology infrastructure, integrating and replacing more than 30 legacy systems. "Lockheed Martin is honored to sustain these critical missions," said Cliff Spier, vice president of Command and Control Solutions for Lockheed Martin Information Systems and 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. The ISC2 program integrates the mission critical networks of NORAD and the two commands, enabling commanders in disparate geographic location to concurrently monitor and assess multi-mission threats.
