US: The US Air Force budget request for fiscal year 2015 includes a USD 215million line item for the Space Fence, an advanced space surveillance system expected to be put under contract in the coming months. Lockheed Martin and Raytheon have developed competing designs for the next-generation Space Fence, a system of ground-based radars that would be capable of tracking golf ball-sized objects in Earth orbit. Air Force officials have said the multibillion-dollar contract award, delayed from last year, is now expected in mid-May.

Previously, the Space Fence was included under a broader budget account called Space Situational Awareness. The Air Force expects to spend USD 731 million on the program through 2019, budget documents show. In 2013, the Air Force reduced the number of planned Space Fence radar sites from two to one, although the development contracts include the option for a second site, if needed, according to the Government Accountability Office. The first site is expected to be built on the Kwajalein Atoll in the Pacific.
