Defense Advanced Research Projects Agency
The Defense Advanced Research Projects Agency (DARPA) is a U.S. government agency established in 1958 by President Dwight D. Eisenhower in response to the Soviet launch of Sputnik. Operating under the Department of Defense, DARPA conducts classified and unclassified research and development projects to maintain American technological superiority and prevent technological surprise. Key activities include advanced weapons systems, sensor technology, directed energy research, and information processing. Notable achievements include ARPANET (foundation of the Internet), stealth technology for aircraft, GPS development, and autonomous vehicles. DARPA emphasizes high-risk, high-reward research through small, flexible project teams with minimal bureaucracy. Most projects remain classified, though many innovations have influenced civilian technology in electronics, telecommunications, and computer science.
