Space Fence on Kwajalein will allow Air Force to monitor debris, threats - Pacific - Stripes Apr 2017
"The Air Force Space Surveillance System, which shut down in 2013 after 50 years, tracked about 20,000 objects. Space Fence, a tracking system being built by Lockheed Martin on the remote South Pacific island of Kwajalein, is expected to be able to track 200,000."

"Space Fence will be able to detect objects as small as marbles at the roughly 250-mile height of the International Space Station. Such a small speck of debris might sound benign, but NASA has replaced space shuttle windows damaged by flying paint flecks."
