Stanley R. Mickelsen SAFEGUARD Complex

SRMSC Site Future

Currently, the Cavalier County Job Development Authority’s largest project is the redevelopment and acquisition of the eastern third of the Stanley R. Mickelsen SAFEGUARD Complex Missile Site Radar.

The Cavalier County Job Development Authority (CCJDA)  is seeking respondents to an Expression of Interest regarding both the redevelopment of certain portions of the existing and now decommissioned Stanley R. Mickelsen Safeguard Complex (the “SRMSC”) and development of the greenfield portion of the site totaling almost 200 acres and 235,000 sq.ft. of shell space.  To view the EOI please click here.

From industry outreach and trends, the CCJDA understands that this site appears well regarded as a location where both secure and top-secret/highly-secure Data Centers can be constructed due to the location and secure-site history, in addition to other site and community development features including but not limited to a distribution warehousing hub, hotel, Industrial Park, and museum/site experience of the existing SRMSC.  

In its time, the SAFEGUARD System was the largest processor in the free world with an overall processing capability of 22.5 million instructions per second assuring the smooth operation and response in real-time to ballistic missile threats. It had redundant emergency generators, dual power systems, thermal storage tank and raised floor computational rooms; and a hardened concrete shell

SRMSC Site History
The Stanley R. Mickelsen SAFEGUARD Complex (SRMSC) was authorized by congress in 1969, construction began the following year, and Northeastern North Dakota thrived. The population of the community of Langdon swelled from 2,180 in 1970 to over 4,500 in 1974. In January of 1973 installation and testing of components at the Missile Site Radar (MSR) Complex and Remote Site Launch sites began and by December of 1973 live satellite tracking had been accomplished.

Limited operations began in October of 1974 at which time the equipment was manned by command personnel twenty-four hours a day, seven days a week. In April of 1975 initial operational capability at the SRMSC was achieved. Stages of operational capability were determined by how many missiles were in the ground. The site became fully operational on October 1, 1975 when 100% of the missiles were in the ground. Then, the following day, October 2, 1975 Congress voted to deactivate the system. Keys to the system were pulled on February 10, 1976 at 2:58 pm. On January 3, 1979 the doors to the MSR pyramid were welded shut. Overall the government had spent $5.7 billion on the site.
