The PAVE Phased Array Warning System (PAVE PAWS) was a Cold War system of computer and radar equipment developed to "detect and characterize a sea-launched ballistic missile attack against the United States". With the first solid-state phase-scanned array deployed, the system at the perimeter of the contiguous United States used a pair of Raytheon AN/FPS-115 Radar Sets at each site (2 sites in 1980, then 2 more used 1987–95) as part of the United States Space Surveillance Network.
