In the early years of the Cold War, the U.S. Air Force had a problem--it lacked early warning capabilities that could detect Soviet nuclear bombers flying towards North America from the North Pole. At the time, the Air Force needed three to six hours of advanced warning to disperse Strategic Air Command bombers, launch air-defense interceptors, and implement civil defense measures. The issue was brought to the Massachusetts Institute of Technology Summer Study Group in 1952, where a team of 20 engineers and scientists examined US radar shortfalls and ultimately recommended the construction of Distant Early Waring Line Radars that would stretch across the 69th parallel, from the northwest corner of Alaska, to Baffin Island on the east coast of Canada. An early warning system employed at this latitude would give the Air Force hours to prepare for nuclear strikes, but quickly building this complex line of automated radar systems across the desolate Arctic landscape was easier said than done.
