Editing Safeguard Program (section)

==Components==
The Safeguard system consisted of several primary components, the Perimeter Acquisition Radar, the Missile Site Radar, the Spartan missile launchers, co-located Sprint missile launchers, and Remote Sprint missile launchers.{{citation needed|date=September 2015}}

===Perimeter Acquisition Radar (PAR)===
[[Image:Cavalierairforcestationparcs.jpg|thumb|right|The PAR, known now as PARCS (for Perimeter Acquisition Radar Cueing System) is still operational]]

The PAR was a large [[passive electronically scanned array]] radar that was intended to detect incoming ballistic missile warheads as they crossed over the North Pole region.  Potential targets detected by the PAR would be sent to the Missile Site Radar (MSR) and to [[North American Aerospace Defense Command]].  Two radar sites were intended to be constructed on the northern border of the United States, one in Montana and one in North Dakota.  Construction was begun at both locations, but because of the ratification of the [[Anti-Ballistic Missile Treaty]], only the site at North Dakota was completed.  That site, near [[Cavalier, North Dakota]], is now operated by the [[United States Space Force]] as [[Cavalier Space Force Station]].<ref>[https://www.buckley.spaceforce.mil/News/Article-Display/Article/2715043/cavalier-afs-renamed-as-us-space-force-installation/ Cavalier AFS renamed as U.S. Space Force installation]</ref>

Remnants of the Montana PAR site are located east of [[Conrad, Montana]], at {{coord|48|17|15.83|N|111|20|32.39|W|type:landmark}}.

===Missile Site Radar (MSR)===
The Missile Site Radar was the control of the Safeguard system. It housed the computers and a phased array radar necessary to track and hit back at incoming ICBM warheads. The radar building itself is a pyramid structure several stories tall. Construction was begun in both Montana and North Dakota, but only the North Dakota site remains standing. The MSR complex included 30 Spartan missile launchers and 16 Sprint missile launchers.<ref>{{cite web |url=https://srmsc.org/images1/7002c.jpg |title=SRMSC Reunion - MSR site large map |access-date=December 25, 2021}}</ref>

Remnants of the Montana MSR site {{coord|48.13831|-111.76152}} were dismantled and buried.<ref>{{cite web |url=https://srmsc.org/mnt0040.html |title=SRMSC Reunion - Montana MSR Trip Report |access-date=December 25, 2021}}</ref>

===Remote Sprint Launchers (RSL)===
Remote Sprint Launchers were established around the MSR main complex in order to place missile launchers closer to their intended targets, and thus reduce the flight range to the targets. Four sites were completed, and they still remain there, {{convert|10|to|20|mi}} around the MSR complex in [[Nekoma, North Dakota]].<ref>{{cite web |url=https://srmsc.org/run0120.html |title=SRMSC Reunion - RSL Tour Guide |access-date=December 25, 2021}}</ref>
