The Stanley R. Mickelsen Safeguard Complex (SRMSC) was a cluster of military facilities near Nekoma, North Dakota, that supported the United States Army's Safeguard anti-ballistic missile program. The complex provided launch and control for 30 LIM-49 Spartan anti-ballistic missiles, and 70 shorter-range Sprint anti-ballistic missiles. The deployment area of the complex covered the Minuteman launchers of the 321st Strategic Missile Wing, based at Grand Forks Air Force Base, North Dakota.
