PAVE PAWS (Precision Acquisition Vehicle Entry Phased Array Warning System) is a complex Cold War early warning radar and computer system developed in 1980 to "detect and characterize a sea-launched ballistic missile attack against the United States". With the first solid-state phased 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 (two sites in 1980, then two more used 1987–95) as part of the United States Space Surveillance Network. One system was sold to Taiwan and is still in service.
