No.

While the U.S. Congress voted to decommission Nekoma Pyramid a day after it became fully operational, the ballistic missile defense site continued to operate for around six more months before it was shut down.

The North Dakota News Cooperative is partnering with Gigafact to produce timely fact briefs, which are quick, evidence-based fact checks about trending claims relevant to North Dakota.

The Stanley R. Mickelsen Safeguard Complex, commonly called the Nekoma Pyramid, achieved initial operating capability on April 1, 1975 and full operational capability on October 1, 1975. The next day, Congress voted to shut down the entire Safeguard missile defense program, citing high costs, limited effectiveness, and arms control concerns.

While the vote came just one day after the system reached full operational status, the shutdown process was not immediate. The Nekoma site, along with its supporting radar and Cinterceptor installations, remained active until April 1976.

The decision affected other planned Safeguard locations, which were canceled or never completed. The October 2 vote effectively ended the nation’s first and only operational anti-ballistic missile defense network.

This fact brief is responsive to conversations such as this one.
