Defense Advanced Research Projects Agency

From Wikipedia, the free encyclopedia

The Defense Advanced Research Projects Agency (DARPA) is an agency of the United States Department of Defense responsible for the development of new technology for use by the military. DARPA was responsible for funding development of many technologies which have had a major impact on the world, including computer networking (starting with the ARPANET, which eventually grew into the Internet), as well as NLS, which was both the first hypertext system, and an important precursor to the contemporary ubiquitous graphical user interface.

Its original name was simply Advanced Research Projects Agency (ARPA), but it was renamed DARPA (for Defense) on March 23, 1972, then back to ARPA on February 22, 1993, and then back to DARPA again on March 11, 1996

DARPA was established in 1958 in response to the Soviet launching of Sputnik in 1957, with the mission of keeping the US's military technology ahead of its enemies. DARPA is independent from other more conventional military R&D and reports directly to senior Department of Defense management. DARPA has around 240 personnel (about 140 technical) directly managing a $3.2 billion budget. These figures are "on average" since DARPA focuses on short-term (two to four-year) projects run by small, purpose-built teams.

[edit] DARPA's Mission

From DARPA's own introduction (pdf): "DARPA is a Defense Agency with a unique role within DoD. DARPA is not tied to a specific operational mission: DARPA supplies technological options for the entire Department, and is designed to be the “technological engine” for transforming DoD.

Near-term needs and requirements generally drive the Army, Navy, Marine Corps, and Air Force to focus on those needs at the expense of major change. Consequently, a large organization like DoD needs a place like DARPA whose only charter is radical innovation.

DARPA looks beyond today’s known needs and requirements. As military historians note, “None of the most important weapons transforming warfare in the 20th century – the airplane, tank, radar, jet engine, helicopter, electronic computer, not even the atomic bomb – owed its initial development to a doctrinal requirement or request of the military.” None of them. And to this list, DARPA would add unmanned systems, Global Positioning System (GPS) and Internet technologies.

DARPA’s approach is to imagine what capabilities a military commander might want in the future and accelerate those capabilities into being through technology demonstrations. These not only provide options to the commander, but also change minds about what is technologically possible today."

DARPA was created as the Advanced Research Projects Agency (ARPA), by Public Law 85-325 and Department of Defense Directive 5105.41, in February 1958. Its creation was directly attributed to the launching of Sputnik and to U.S. realization that the Soviet Union had developed the capacity to rapidly exploit military technology. Additionally, the political and defense communities recognized the need for a high-level Department of Defense organization to formulate and execute R&D projects that would expand the frontiers of technology beyond the immediate and specific requirements of the Military Services and their laboratories. In pursuit of this mission, DARPA has developed and transferred technology programs encompassing a wide range of scientific disciplines which address the full spectrum of national security needs.

From 1958-1965, ARPA's emphasis centered on major national issues, including space, ballistic missile defense, and nuclear test detection. In 1960, all of its civilian space programs were transferred to the National Aeronautics and Space Administration (NASA) and the military space programs to the individual Services. This allowed DARPA to concentrate its efforts on the DEFENDER (defense against ballistic missiles), Project Vela (nuclear test detection), and AGILE (counterinsurgency R&D) Programs, and to begin work on computer processing, behavioral sciences, and materials sciences. The DEFENDER and AGILE Programs formed the foundation of DARPA sensor, surveillance, and directed energy R&D, particularly in the study of radars, infrared sensing, and x-ray/gamma ray detection.

In the late 1960s, with the transfer of these mature programs to the Services, ARPA redefined its role and concentrated on a diverse set of relatively small, essentially exploratory research programs. The Agency was renamed the Defense Advanced Research Projects Agency (DARPA) in 1972, and in the early 1970s, it emphasized direct energy programs, information processing, and tactical technologies.

In the area of information processing, DARPA made great strides, initially through its support of the development of time-sharing (all modern operating systems are descendants of the Multics system, developed by a cooperation between Bell Labs, General Electric and MIT, which DARPA supported by funding Project MAC at MIT with an initial two-million-dollar grant), and later through the evolution of the ARPANET (a telecommunications network and precursor to the Internet), and research in the artificial intelligence (AI) fields of speech recognition and signal processing. DARPA also funded the development of the Douglas Engelbart's NLS computer system and the Aspen Movie Map, which was probably the first hypermedia system and an important precursor of virtual reality.

The controversial Mansfield Amendment of 1973 expressly limited appropriations for defense research (through ARPA/DARPA) to projects with direct military application. Some contend that the amendment devastated American science, since ARPA/DARPA was a major funding source for basic science projects at the time; the National Science Foundation never took up the slack as expected. But the resulting brain drain is also credited with boosting the development of the fledgling personal computer industry. Many young computer scientists fled from the universities to startups and private research labs like Xerox PARC.

From 1976-1981, DARPA's major thrusts were dominated by air, land, sea, and space technology, such as follow-on forces attack with standoff weapons and associated Command, Control, and Communications; tactical armor and anti-armor programs; infrared sensing for space-based surveillance; high-energy laser technology for space-based missile defense; antisubmarine warfare; advanced cruise missiles; advanced aircraft; and defense applications of advanced computing. These large-scale technological program demonstrations were joined by integrated circuit research, which resulted in submicron electronic technology and electron devices that evolved into the Very Large Scale Integration (VLSI) Program and the Congressionally mandated charged particle beam program. Many of the successful programs were transitioned to the Services, such as the foundation technologies in automatic target recognition, space based sensing, propulsion, and materials that were transferred to the Strategic Defense Initiative Organization (SDIO), now known as the Ballistic Missile Defense Organization (BMDO).

During the 1980s, the attention of the Agency was centered on information processing and aircraft-related programs, including the National Aerospace Plane (NASP) or Hypersonic Research Program. The Strategic Computing Program enabled DARPA to exploit advanced processing and networking technologies and to rebuild and strengthen relationships with universities after the Vietnam War. In addition, DARPA began to pursue new concepts for small, lightweight satellites (LIGHTSAT) and directed new programs regarding defense manufacturing, submarine technology, and armor/anti-armor.

[edit] Current organization

DARPA has eight program offices, all of which report to DARPA director Dr. Anthony J. Tether. (Note that as of July 2006 SPO and ATO have been merged into a single Strategic Technology Office (STO) that complements the Tactical Technology Office (TTO) as one of the two "systems" offices.)

The Advanced Technology Office (ATO) researches, demonstrates, and develops high payoff projects in maritime, communications, special operations, command and control, and information assurance and survivability mission areas.
The Defense Sciences Office (DSO) vigorously pursues the most promising technologies within a broad spectrum of the science and engineering research communities and develops those technologies into important, radically new military capabilities.
The Information Processing Technology Office (IPTO) focuses on inventing the networking, computing, and software technologies vital to ensuring DOD military superiority.
The Information Exploitation Office (IXO) develops sensor and information system technology and systems with application to battle space awareness, targeting, command and control, and the supporting infrastructure required to address land-based threats in a dynamic, closed-loop process. IXO leverages ongoing DARPA efforts in sensors, sensor exploitation, information management, and command and control, and addresses systemic challenges associated with performing surface target interdiction in environments that require very high combat identification confidence and an associated low likelihood for inadvertent collateral damage.
The Microsystems Technology Office (MTO) mission focuses on the heterogeneous microchip-scale integration of electronics, photonics, and microelectromechanical systems (MEMS). Their high risk/high payoff technology is aimed at solving the national level problems of protection from biological, chemical and information attack and to provide operational dominance for mobile distributed command and control, combined manned/unmanned warfare, and dynamic, adaptive military planning and execution.
The Special Projects Office (SPO) researches, develops, demonstrates, and transitions technologies focused on addressing present and emerging national challenges. SPO investments range from the development of enabling technologies to the demonstration of large prototype systems. SPO is developing technologies to counter the emerging threat of underground facilities used for purposes ranging from command-and-control, to weapons storage and staging, to the manufacture of weapons of mass destruction. SPO is also developing significantly more cost-effective ways to counter proliferated, inexpensive cruise missiles, UAVs, and other platforms used for weapon delivery, jamming, and surveillance. SPO is investing in novel space technologies across the spectrum of space control applications including rapid access, space situational awareness, counterspace, and persistent tactical grade sensing approaches including extremely large space apertures and structures.
The Tactical Technology Office (TTO) engages in high-risk, high-payoff advanced military research, emphasizing the "system" and "subsystem" approach to the development of aeronautic, space, and land systems as well as embedded processors and control systems.

[edit] ARPA and DARPA in fiction

In the video game series Metal Gear Solid, both ARPA and DARPA are mentioned as part of the plotline, and references how ARPA eventually became DARPA in the future. In these games, DARPA funded and created an experimental battle tank that utilises a bipedal design and is capable of carrying nuclear warheads, alongside a compliment of conventional weaponry including cannons, rocket launchers, a rail gun, and a futuristic laser rifle. This vehicle was named "Metal Gear REX".

DARPA is mentioned in the Matthew Reilly books Temple and Hell Island. In Temple, DARPA plays a role in creating the super thermonuclear missile, the "Supernova". In Hell Island, DARPA is part of the villains testing out a "super trooper" experiment.

DARPA and ARPA are brought into context in episodes of The West Wing. In one, a DARPA employee, Dr. Max Milkman, discusses the difference between the two, and focuses on some of the organization's operations and projects.

In James Rollins' books "Map of Bones" and "Black Order" the main characters are part of a fictional organization called Sigma, a covert branch of DARPA, tasked with safeguarding, acquiring, or neutralizing "technologies vital to U.S. security."

In "The Patriot" Steven Seagal's character was a former DARPA scientist who specialized in biological research.
