DARPA

The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense. It was created on February 7, 1958, by President Dwight D. Eisenhower after the Soviet Union launched Sputnik 1 in 1957. DARPA works with universities, companies, and government groups to develop new technologies for the military.

DARPA has helped create many important technologies we use today, such as weather satellites, GPS, drones, stealth technology, voice interfaces, the personal computer, and the internet. Because of its success, many other countries have started their own research agencies.

DARPA is led by Stephen Winchell and has about 220 government employees. These employees manage around 250 research and development programs, working on projects that push the limits of technology and science.

History

Early history (1958–1969)

The Advanced Research Projects Agency (ARPA) was created in 1958 by President Dwight D. Eisenhower after the Soviet Union launched the first satellite, Sputnik. Its job was to work on new technology ideas that could help the military, but often went beyond what the military needed right away. It started with about 150 people and $520 million.

ARPA worked on many important projects. When NASA began in 1958, ARPA gave its space projects to NASA. This let ARPA focus on riskier and more unusual research. ARPA helped start the Internet by supporting a network called ARPANET. It also worked on missile defense, nuclear test detection, and new computer ideas.

Later history (1970–1980)

In the 1970s, laws limited ARPA to projects that had clear military uses. This caused many bright scientists to leave for private companies, helping start the personal computer industry. ARPA worked on technology for airplanes, ships, and space, as well as new computing ideas.

Recent history (1981–present)

In the 1980s and beyond, ARPA, later renamed DARPA, kept working on new technology. It explored fast airplanes, small satellites, and new ideas for defense. In recent years, DARPA has worked on computer security, new vehicles, and even ideas for space travel. It has also started prize competitions to encourage new inventions.

Organization

DARPA has six main technical offices that manage its research projects, plus two special project offices. All of these offices report to the DARPA director.

The Defense Sciences Office (DSO) looks for new, exciting research ideas in science and engineering that could become important technologies for U.S. national security. The Information Innovation Office (I2O) works to keep U.S. technology strong in areas where information gives a military advantage. The Microsystems Technology Office (MTO) develops tiny, smart microsystems and parts to keep U.S. leadership in important military systems. The Strategic Technology Office (STO) focuses on technologies that affect large areas and involve many military services. The Tactical Technology Office (TTO) does advanced military research on airplanes, space systems, and land vehicles. The Biological Technologies Office (BTO) started in 2014 to bring together biology, engineering, and computer science for national security.

In the past, DARPA had other offices with different focuses, like helping soldiers use new technologies and developing ways to protect against underground threats. These offices have since changed or been combined.

Directors of DARPA have included many leaders over the years.

Projects

A list of DARPA's active and archived projects is available on the agency's website. Because of the agency's fast pace, programs constantly start and stop based on the needs of the U.S. government. Structured information about some of the DARPA's contracts and projects is publicly available.

Notable fiction

DARPA is often shown in books, TV shows, and movies because it is a high-tech government agency. It appears in stories like Tom Swift and the Visitor from Planet X, where it helps with a technical problem. DARPA is also mentioned in TV shows such as The West Wing and Numb3rs, as well as in the Netflix film Spectral.
