# MIT Lincoln Laboratory

The MIT Lincoln Laboratory, located in Lexington, Massachusetts, is a United States Department of Defense federally funded research and development center chartered to apply advanced technology to problems of national security. Research and development activities focus on long-term technology development as well as rapid system prototyping and demonstration. Its core competencies are in sensors, integrated sensing, signal processing for information extraction, decision-making support, and communications. These efforts are aligned within ten mission areas. The laboratory also maintains several field sites around the world.
The laboratory transfers much of its advanced technology to government agencies, industry, and academia, and has launched more than 100 start-ups.

## History
### Origins

At the urging of the United States Air Force, the Lincoln Laboratory was created in 1951 at the Massachusetts Institute of Technology (MIT) as part of an effort to improve the U.S. air defense system. Primary advocates for the creation of the laboratory were veterans of the World War II-era MIT Radiation Laboratory, including physicist and electrical engineer Ivan A. Getting, physicist Louis Ridenour, and physicist George E. Valley Jr.
The laboratory's inception was prompted by Valley's investigations into the U.S. air defences, culminating in the Air Defense Systems Engineering Committee's 1950 report that concluded the United States was unprepared for the threat of an air attack. Because of MIT's management of the Radiation Laboratory during World War II, the experience of some of its staff on the Air Defense Systems Engineering Committee, and its proven competence in advanced electronics, the Air Force suggested that MIT could provide the research needed to develop an air defense that could detect, identify, and ultimately intercept air threats.
James R. Killian, the president of MIT, was not eager for MIT to become involved in air defense. He asked the United States Air Force if MIT could first conduct a study to evaluate the need for a new laboratory and to determine its scope. Killian's proposal was approved, and a study named Project Charles (for the Charles River that flows past MIT) was carried out between February and August 1951. The final Project Charles report stated that the United States needed an improved air defense system and unequivocally supported the formation of a laboratory at MIT dedicated to air defense problems.
This new undertaking was initially called Project Lincoln, and the site chosen for the new laboratory was on the Laurence G. Hanscom Field (now Hanscom Air Force Base), where the Massachusetts towns of Bedford, Lexington and Lincoln meet. A Project Bedford (on antisubmarine warfare) and a Project Lexington (on nuclear propulsion of aircraft) were already in use, so Major General Putt, who was in charge of drafting the charter for the new laboratory, decided to name the project for the town of Lincoln.

### SAGE

The Semi-Automatic Ground Environment (SAGE) Air Defense System is the beginning of MIT Lincoln Laboratory's history of developing innovative technology. The system was conceived to meet the challenge of providing air defense to the continental United States. SAGE was designed to collect, analyze, and finally relay data from a multitude of radars, all quickly enough that defense responses could be initiated, if needed. The key to this system was a computer that could perform reliably in real time.
MIT's Whirlwind computer, built in the 1940s, looked to be a possible candidate for the system. However, the Whirlwind was not reliable or fast enough for the processing needed for analyzing data coming in from dozens of, perhaps even 100, radars. Jay Wright Forrester, an MIT professor instrumental in the development of the Whirlwind, found the breakthrough to enable the computer to achieve outstanding reliability and doubled speed — the magnetic-core memory. The magnetic-core memory revolutionized computing. Computers became machines that were not just large and fast calculators; their uses for varying applications grew. Industry followed this development closely, adopting the magnetic-core memory that expanded the capabilities of computers.
The TX-0 computer, in essence, a transistorized version of Whirlwind, was built in 1955 and made operational in 1956. It was smaller and slightly faster than Whirlwind.
Whirlwind II was not completed, but the AN/FSQ-7 Combat Direction Central, based on elements of its design, became the command and control system for the SAGE air defense network and Lincoln Laboratory Division 6 participated in this development.
Lincoln Laboratory quickly established a reputation for pioneering advanced electronics in air defense systems. Many of the technical developments that later evolved into improved systems for the airborne detection and tracking of aircraft and ground vehicles have formed the basis for current research.

### Today

Since MIT Lincoln Laboratory's establishment, the scope of the problems has broadened from the initial emphasis on air defense to include programs in space surveillance, missile defense, surface surveillance and object identification, communications, cyber security, homeland protection, high-performance computing, air traffic control, and intelligence, surveillance, and reconnaissance (ISR). The core competencies of the laboratory are in sensors, information extraction (signal processing and embedded computing), communications, integrated sensing, and decision support, all supported by a strong advanced electronic technology activity.
Lincoln Laboratory conducts research and development pertinent to national security on behalf of the military services, the Office of the Secretary of Defense, and other government agencies. Projects focus on the development and prototyping of new technologies and capabilities. Program activities extend from fundamental investigations, through simulation and analysis, to design and field testing of prototype systems. Emphasis is placed on transitioning technology to industry.
The work of Lincoln Laboratory revolves around a comprehensive set of mission areas:
* Space control
* Air, missile, and maritime defense technology
* Communication systems
* Cybersecurity and information sciences
* Intelligence, surveillance, and reconnaissance systems and technology
* Advanced technology
* Tactical systems
* Homeland protection
* Air traffic control
* Engineering
* Biotechnology
Lincoln Laboratory also undertakes work for non-DoD agencies such as programs in space lasercom and space science, as well as environmental monitoring for NASA and the National Oceanic and Atmospheric Administration.
The dissemination of information to the government, academia, and industry is a principal focus of Lincoln Laboratory's technical mission. Wide dissemination of technical information is achieved through annual technical workshops, seminars, and courses hosted at the laboratory. Toward the goal of knowledge sharing, the laboratory publishes the Lincoln Laboratory Journal, which contains comprehensive articles on current major research and journalistic pieces highlighting novel projects. Other publications include "Tech Notes", brief descriptions of Laboratory capabilities and technical achievements; the "Annual Report", which highlights technical accomplishments and ongoing corporate and community outreach initiatives; and an overview brochure "MIT Lincoln Laboratory: Technology in Support of National Security". Current news about Laboratory technical milestones is featured on the laboratory's website.
MIT Lincoln Laboratory maintains a strong relationship with the MIT campus. Ongoing research collaborations, student internship programs, reciprocal seminar series, and cooperative community and educational outreach projects are just a few of the ways the laboratory and the campus share the talents, facilities, and resources of each other.

## Staff and organization

Approximately 1,700 technical staff members work on research, prototype building, and field demonstrations. The technical staff come from a broad range of scientific and engineering fields, with electrical engineering, physics, computer science and mathematics being among the most prevalent. Two-thirds of the professional staff hold advanced degrees, and 60% of those degrees are at the doctoral level.
The technical work is organized into eight divisions: Air, Missile, & Maritime Defense Technology; Homeland Protection and Air Traffic Control; Cyber Security and Information Sciences; Communication Systems; Engineering; Advanced Technology; Space Systems and Technology; and ISR and Tactical Systems.
Lincoln Laboratory supports its research and development work with an infrastructure of services from six departments: Contracting Services, Facility Services, Financial Services, Information Services, Security Services, and Human Resources. Approximately 1300 people working in the service departments or as technical specialists support the research and development mission of the laboratory.
Lincoln Laboratory supports several community outreach programs. Programs that promote education in science, technology, engineering, and mathematics for students in grades kindergarten to high school are offered to the local community and are supported by volunteers from across the laboratory. The Lincoln Laboratory community service program raises awareness of both local and national needs by organizing fund-raising and outreach events that support selected charitable organizations, medical research, and U.S. troops abroad.

### Field sites
#### Lincoln Space Surveillance Complex

Since 1995, the Lincoln Space Surveillance Complex in Westford, Massachusetts, has played a key role in space situational awareness and the laboratory's overall space surveillance mission. The site comprises three major radars – Millstone Deep-Space Tracking Radar (an L-band radar), Haystack Long-Range Imaging Radar (W-band and X-band), and the Haystack Auxiliary Radar (Ku-band). Lincoln Laboratory is also engaged in field work at sites in the continental U.S. and the Pacific region.

#### Reagan Test Site, Kwajalein Atoll, Marshall Islands

Lincoln Laboratory serves as the scientific advisor to the Reagan Test Site at the U.S. Army Kwajalein Atoll installation located about 2500 miles WSW of Hawaii. The laboratory also supports upgrades to the command-and-control infrastructure of the range to include applications of real-time discrimination and decision aids developed as a result of research at the laboratory.

#### The Experimental Test Site at White Sands Missile Range

The Lincoln Laboratory Experimental Test Site (ETS; obs. code: 704) is an electro-optical test facility located on the grounds of the White Sands Missile Range in Socorro, New Mexico. The ETS is operated by the laboratory for the Air Force; its principal mission is the development, evaluation, and transfer of advanced electro-optical space surveillance technologies. The ETS has been a contributing sensor to the U.S. Air Force Space Command. A spin-off program for NASA, Lincoln Near-Earth Asteroid Research (LINEAR), uses the ground-based electro-optical deep-space surveillance telescopes at White Sands to discover comets and asteroids, in particular near-Earth objects. A large percentage share of all known minor planets in the Solar System have been discovered through this program. As of 2020, the Minor Planet Center credits LINEAR with the discovery of 149,793 minor planets from 1997 to 2012. In terms of the total number of discoveries, LINEAR is the most successful asteroid survey program ever conducted.
In 2013, NASA's lunar-orbiting Lunar Atmosphere and Dust Environment Explorer (LADEE) carried an optical communications terminal built by Lincoln Laboratory that communicated with a ground terminal at another site at the White Sands Missile Range. This system, the Lunar Laser Communication Demonstration (LLCD) transmitted data in both directions at the fastest speeds ever recorded for deep-space communication. The demonstration is now being followed by a number of optical systems that will allow much higher volumes of data transfer for both scientific discovery and human exploration.
