USAF Space Fence Program on hold

The U.S. Air Force is ready to award a long-overdue contract for its next-generation space-object tracking system, but the project is being held up due to a Pentagon review of its major acquisition program.
Lockheed Martin Mission Systems and Sensors, and Raytheon Integrated Defense Systems, have developed competing designs for the next-generation Space Fence, a system of ground-based radars that would be capable of tracking greater numbers of smaller objects than the current system.
