On This Day in Telephone History February 25TH 1955

On This Day in Telephone History February 25TH 1955 the SAGE plan for Semiautomatic Air Defense System appeared in AT&T’s Ownership and Encumbrance Report (O&E).

Shortly after, the Air Force awarded a contract to Western Electric for the construction and operation of a radar and communications network across northern Canada. SAGE was the nation’s first air defense system and was the impetus for the establishment of MIT Lincoln Laboratory. The Department of Defense (DoD) reevaluated the nation’s defenses against nuclear attack. As a part of the process, the DoD assigned the U.S. Air Force the task of improving the nation’s air defense system. The Air Force, in turn, asked the Massachusetts Institute of Technology for assistance and this led to the formation of MIT Lincoln Laboratory.
