'''{{PAGENAME}} Long Range Missile Detection Radar Set''' - A Long Range Missile Detection Radar set built by Raytheon in the late 1970s. Designed to detect sea launched ballistic missiles (SLBM). Deployed in a system called Pave Paws.

The initial concept had two FPS-115 systems deployed in the continental United States in 1980, one on the east coast at [[Cape Cod Air Force Station|Cape Cod AFS]] and one on the west coast at [[Beale AFB Pave Paws Radar Site|Beale AFB]]. The concept expanded in the mid 1980s with two more sites, one at Dobbins AFB Georgia and one at [[Eldorado Air Force Station|Eldorado AFS]], Texas. Coincident with the end of the [[Cold War]] both of the later sites were closed in 1995. The equipment at [[Eldorado Air Force Station|Eldorado AFS]], was relocated to [[Clear Air Force Station|Clear AFS]], Alaska to replace the FPS-50.

Additional FPS-115 Pave Paws radars were installed in the 1990s at BMEWS sites at Thule, Greenland, and Fylingdale Moor, England.
