Post-Attack Command and Control System Facility, Hadley is a defunct Post-Attack Command and Control System facility that operated from June 2, 1958 until 1970. It is located on and under Bare Mountain in Hadley, Massachusetts. The facility was known by many different names: 8th Air Force Combat Operations Center (COC), "The Notch", and "Westover Communications Annex" since it was related to nearby Westover Air Force Base.
The facility has been described as having two underground stories amounting to 40,000 square feet. It was designed to house 135 people.
In 1957, Strategic Air Command began construction for a hardened bunker to contain the command post for the 8th Air Force, which was located at nearby Westover Air Force Base, Chicopee, Massachusetts. The facility was located inside Bare Mountain, off Route 116, and was nicknamed "The Notch." The underground facility, built into the side of Bare Mountain, was hardened to protect it from the effects of a nearby nuclear blast and designed so that the senior military staff could facilitate further military operations.
The facility was shut down in 1970, when the 8th Air Force was relocated to Barksdale Air Force Base, Louisiana. After the U.S. Air Force abandoned the site in 1970, the Federal Reserve took over and used it as a secure storage facility for their records. Allegedly they stored large sums of money there as well, to be used to restart the economy after a nuclear war.
