KWAJALEIN ATOLL, Marshall Islands, March 24 (UPI) -- Construction of facilities for the new Space Fence radar system has been started in the Marshall Islands by the U.S. Air Force and Lockheed Martin.
Space Fence is an S-band ground-based radar system. It will replace the 1960s Air Force Space Surveillance System to track objects in orbit around the Earth and increase the ability to predict and prevent space-based collisions.
