Massachusetts played a pivotal role during the Cold War era. In 1957, the Strategic Air Command established the Notch Bunker, a three-story hardened facility built into the Holyoke Mountain Range near Westover Air Force Base. The state led the nation with a groundbreaking $3 million underground Emergency Operations Center in Framingham, dedicated on November 16, 1963, designed to run state government post-nuclear blast, capable of withstanding a twenty-megaton missile explosion within three miles. In 1964, AT&T constructed a forty-thousand-square-foot underground bunker in Chesterfield, built for both military and civilian purposes, intended to resist nuclear, biological and chemical attacks. By 1966, there were a total of 6,623 fallout shelters in Massachusetts. Utilizing vintage photographs and maps, local author Joshua Shanley explores the state's bunkers, bases and missile silos and their impact on current emergency planning.
