Project Lincoln at MIT was under the cognizance of the ERD, and the integration of the project s radars became a major activity at the ERD . In March 1952, radar data was sent from Bedford to the Whirlwind computer at MIT over an 8-digit telephone link developed by the ERD, allowing the first fully automated aircraft interception using SAGE . By the end of 1952, there were 12 radars operating at Cape Cod in the experimental SAGE system.
