The U.S. Nuclear Weapons Cost Study Project was completed in August 1998 and resulted in the book Atomic Audit: The Costs and Consequences of U.S. Nuclear Weapons Since 1940 edited by Stephen I. Schwartz. These project pages should be considered historical.
An aerial view of the Stanley R. Mickelson Safeguard complex in Nekoma, North Dakota, the only operational antiballistic missile system ever deployed by the United States.
The pyramid-shaped building is the missile site radar, used to track incoming missiles and guide Spartan and Sprint missiles to their targets. A separate long-range detection radar was located further north at Concrete, North Dakota. The missile field in the foreground contains reinforced underground launchers for thirty Spartan and sixteen Sprint missiles (an additional fifty or so Sprint missiles were deployed at four remote launch sites). The complex was deactivated in 1976 after being operational for less than four months.
