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.
Workers building the new underground command post for the Strategic Air Command, circa 1955
To provide some protection against the effects of a Soviet nuclear strike, the Strategic Air Command (SAC) decided to bury its new headquarters building underground at Offutt Air Force Base in Omaha, Nebraska. Construction began on April 16, 1955 and was completed in 1956, at a cost of about $65 million (in constant 1996 dollars). On June 1, 1992, SAC became the U.S. Strategic Command.
