MIT Lincoln Laboratory

MIT Lincoln Laboratory is a federally funded research and development center (FFRDC) managed by the Massachusetts Institute of Technology on behalf of the United States Department of Defense. Located at Hanscom Air Force Base in Lexington, Massachusetts, it was established in 1951 to develop an air defense system for the United States.

An outgrowth of wartime radar research at MIT, the lab's first project produced the Semi-Automatic Ground Environment (SAGE), the first large-scale computerized command-and-control network. After SAGE, the laboratory's mission broadened into radar, space surveillance, satellite communications, and solid-state electronics. Among its largest spinoffs were the MITRE Corporation, spun off in 1958 to manage SAGE deployment, and Digital Equipment Corporation, founded in 1957 by former Lincoln staff. The laboratory's defense work has centered on sensor technology, signal processing, and system prototyping; it designs and tests advanced systems, then transfers the resulting technology to industry for production.

Lincoln also has significant non-defense research programs. Its early computing work produced Reed–Solomon codes and Sketchpad, a foundational program for computer graphics. Its solid-state research contributed to the development of the semiconductor diode laser. For the Federal Aviation Administration, it developed the Terminal Doppler Weather Radar and the Traffic Alert and Collision Avoidance System, both now standard in civil aviation. The Lincoln Near-Earth Asteroid Research (LINEAR) program discovered more near-Earth asteroids than any other survey.

The laboratory employs approximately 4,500 people and operates on an annual budget exceeding $1 billion, the majority of which comes from the Department of Defense. It follows a research-and-prototype model, distinct from defense contractors, and does not compete for production contracts.
