North Warning System : ウィキペディア英語版 | North Warning System
The North Warning System (NWS) is a joint United States and Canadian early-warning radar system for the atmospheric air defense of North America. It provides surveillance of airspace from potential incursions or attacks from across North America's polar region. It replaced the Distant Early Warning Line system in the late 1980s. ==Overview== The NWS consists of both long range AN/FPS-117 and short range AN/FPS-124 surveillance radars, operated and maintained by the North American Aerospace Defense Command (NORAD). The Alaska Regional Operations Control Center (ROCC) at Elmendorf AFB, Alaska controls the stations in Alaska; the Canada East and Canada West Regional Operations Control Centres (ROCCs) at CFB North Bay, Ontario control the stations in Canada. ROCC information is then passed to the NORAD Combat Operations Centre (COC) at Colorado Springs, Colorado.
