The North Warning System (NWS) is an early warning system replacing the old Distant Early Warning (DEW) Line from the early 1950ís. NWS became operational in 1988 and is still being used on a 24/7 basis today.
North Warning System is a US/Canadian program located across northern Alaska and Canada consisting of General Electric AN/FPS-117 Long-Range Radars (LRR) and Unisys AN/FPS-124 shortrange automated Unattended Radars (UARS). The maintenance and control facilities are at the Alaskan Regional Operations Control Center (ROCC) and Canadian Sector Operations Control Center (SOCC). A satcom network provides connectivity between the LRRS, UARS and ROCC/SOCC. Ground-to-Air-to-Ground (G/A/G) communication equipment installed at LRRS provide G/A/G comms between the control centers and airdefense aircraft in those regions.
