===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>
