Johnson and York were both keen on space projects, but when [[NASA]] was established later in 1958 all space projects and most of ARPA's funding were transferred to it. Johnson resigned and ARPA was repurposed to do "high-risk", "high-gain", "far out" basic research, a posture that was enthusiastically embraced by the nation's scientists and research universities.<ref name = Wizards21,22 >"The staff of ARPA saw an opportunity to redefine the agency as a group that would take on the really advanced "far-out" research....The scientific community, predictably, rallied to the call for a reinvention of ARPA as a "high-risk high-gain" research sponsor— the kind of R& D shop they had dreamed of all along" Lyon, Matthew; Hafner, Katie (1999-08-19).

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 that address the full spectrum of national security needs.

From 1958 to 1965, ARPA's emphasis centered on major national issues, including space, [[ballistic missile defense]], and [[nuclear test]] detection.<ref name = Wizards23a >projects in ballistic missile defense and nuclear test detection, couched in terms of basic research, were the top priorities." Lyon, Matthew; Hafner, Katie (1999-08-19). ''Where Wizards Stay Up Late: The Origins of the Internet'' (p. 23). Simon & Schuster. Kindle edition.</ref>  During 1960, all of its civilian space programs were transferred to the [[NASA|National Aeronautics and Space Administration]] ([[NASA]]) and the military space programs to the individual services.<ref>{{Cite web|title=Defense Advanced Research Projects Agency {{!}} United States government|url=https://www.britannica.com/topic/Defense-Advanced-Research-Projects-Agency|access-date=2021-05-19|website=Encyclopedia Britannica|language=en}}</ref>

This allowed ARPA to concentrate its efforts on the Project Defender (defense against ballistic missiles), [[Project Vela]] (nuclear test detection), and [[Project 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 [[radar]], [[infrared]] sensing, and [[x-ray]]/[[gamma ray]] detection.

ARPA at this point (1959) played an early role in [[Transit (satellite)|Transit]] (also called NavSat) a predecessor to the [[Global Positioning System]] (GPS).<ref>{{cite book | title=Transit to Tomorrow.

During 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 during the early 1970s, it emphasized direct energy programs, information processing, and tactical technologies.{{Citation needed|date=April 2020}}

Concerning information processing, DARPA made great progress, initially through its support of the development of [[time-sharing]].  All modern operating systems rely on concepts invented for the [[Multics]] system, developed by a cooperation among [[Bell Labs]], [[General Electric]] and [[MIT]], which DARPA supported by funding [[Project MAC]] at [[Massachusetts Institute of Technology|MIT]] with an initial two-million-dollar grant.<ref>{{cite web|url=http://mit.edu/6.933/www/Fall2001/AILab.pdf |author1=Stefanie Chiou |author2=Craig Music |author3=Kara Sprague |author4=Rebekah Wahba |date=5 Dec 2001 |title=A Marriage of Convenience: The Founding of the MIT Artificial Intelligence Laboratory |url-status=live |archive-url=https://web.archive.org/web/20110514101306/http://mit.edu/6.933/www/Fall2001/AILab.pdf |archive-date=2011-05-14 }}</ref>

DARPA supported the evolution of the [[ARPANET]] (the first wide-area packet switching network), Packet Radio Network, Packet Satellite Network and ultimately, the [[Internet]] and research in the [[artificial intelligence]] fields of speech recognition and signal processing, including parts of [[Shakey the robot]].<ref name="ieee">{{cite web |url=http://ghn.ieee.org/wiki/index.php/Oral-History:Bertram_Raphael |title=Oral History: Bertram Raphael |work=IEEE Global History Network |publisher=[[Institute of Electrical and Electronics Engineers]] |access-date=2012-02-25 |url-status=dead |archive-url=https://web.archive.org/web/20130516195054/http://ghn.ieee.org/wiki/index.php/Oral-History%3ABertram_Raphael |archive-date=2013-05-16 }}</ref> DARPA also supported the early development of both [[hypertext]] and [[hypermedia]]. DARPA funded one of the first two hypertext systems, [[Douglas Engelbart]]'s [[NLS (computer system)|NLS]] computer system, as well as [[The Mother of All Demos]].  DARPA later funded the development of the [[Aspen Movie Map]], which is generally seen as the first hypermedia system and an important precursor of [[virtual reality]].

===Later history (1970–1980)===
The [[Mike Mansfield#Mansfield Amendments|Mansfield Amendment]] of 1973 expressly limited appropriations for defense research (through ARPA/DARPA) only to projects with direct military application.

The resulting "[[Human capital flight|brain drain]]" is credited with boosting the development of the fledgling personal computer industry. Some young computer scientists left the universities to startups and private research laboratories such as [[PARC (company)|Xerox PARC]].

Between 1976 and 1981, DARPA's major projects were dominated by air, land, sea, and space technology, 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.

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|Strategic Defense Initiative Organization]] (SDIO), later known as the [[Ballistic Missile Defense Organization]] (BMDO), now titled the [[Missile Defense Agency]] (MDA).

===Recent history (1981–present)===
During the 1980s, the attention of the Agency was centered on information processing and aircraft-related programs, including the [[Rockwell X-30|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 (DARPA)|LIGHTSAT]]) and directed new programs regarding defense manufacturing, submarine technology, and armor/anti-armor.

In 1981, two engineers, Robert McGhee and Kenneth Waldron, started to develop the Adaptive Suspension Vehicle (ASV) nicknamed the "Walker" at the [[Ohio State University]], under a research contract from DARPA.<ref>{{cite journal |author1=Kenneth J. Waldron |author2=Vincent J. Vohnout |author3=Arrie Pery |author4=Robert B.

However, DARPA lost interest in the ASV, after problems with cold-weather tests.<ref>{{cite web |url=https://library.osu.edu/site/archives/2012/11/30/not-so-long-ago-in-an-osu-engineering-lab-nearby/ |title=Not so long ago, in an OSU engineering lab nearby… |website=The Ohio State University |date=30 November 2012 }}</ref>

On February 4, 2004, the agency shut down its so called "LifeLog Project". The project's aim would have been, "to gather in a single place just about everything an individual says, sees or does".<ref>{{cite magazine|url=https://www.wired.com/2004/02/pentagon-kills-lifelog-project/|title=Pentagon Kills LifeLog Project|first=Wired|last=Staff|magazine=Wired|date=2004-02-04|access-date=2019-03-06}}</ref>

Between 2014 and 2016, DARPA shepherded the first [[Intelligent agent|machine-to-machine]] computer security competition, the [[Cyber Grand Challenge]] (CGC),
bringing a group of top-notch computer security experts to search for security [[Vulnerability (computing)|vulnerabilities]], [[Exploit (computer security)|exploit]] them, and create fixes that patch those vulnerabilities in a fully automated fashion.<ref>{{cite web|url=https://www.yahoo.com/tech/darpa-grand-cyber-challenge-hacking-000000417.html |title=Darpa to create Cyber Grand Challenge to fight security vulnerabilities |last=Howley |first=Daniel |date=17 July 2016 |access-date=17 July 2016 |url-status=live |archive-url=https://web.archive.org/web/20160718190614/https://www.yahoo.com/tech/darpa-grand-cyber-challenge-hacking-000000417.html |archive-date=18 July 2016 }}</ref><ref>{{cite web|url=https://www.darpa.mil/program/cyber-grand-challenge|title=Cyber Grand Challenge (CGC)|publisher=DARPA|access-date=26 April 2020|archive-url=https://web.archive.org/web/20190610210818/https://www.darpa.mil/program/cyber-grand-challenge|archive-date=10 June 2019|url-status=dead}}</ref> It is one of [[DARPA Prize Competitions|DARPA prize competitions]] to spur innovations.

In June 2018, DARPA leaders demonstrated a number of new technologies that were developed within the framework of the [[DARPA GXV-T|GXV-T]] program.

* The [[Tactical Technology Office (DARPA)|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
* The [[Biological Technologies Office (DARPA)|Biological Technologies Office (BTO)]] fosters, demonstrates, and transitions breakthrough fundamental research, discoveries, and applications that integrate biology, engineering, and computer science for national security. Created in April 2014 by then Director [[Arati Prabhakar]], taking programs from the MTO and DSO offices.<ref>{{cite web|url=https://www.darpa.mil/news-events/2014-04-01|title=DARPA Launches Biological Technologies Office |date=1 April 2014 |website=Defense Advanced Research Projects Agency}}</ref>

===Former offices===
* The [[Adaptive Execution Office|Adaptive Execution Office (AEO)]] was created in 2009 by the DARPA Director, [[Regina Dugan]]. The office's four project areas included technology transition, assessment, rapid [[productivity]] and [[adaptive system]]s. AEO provided the agency with robust connections to the warfighter community and assisted the agency with the planning and execution of technology demonstrations and field trials to promote adoption by the warfighter, accelerating the transition of new technologies into DoD capabilities.
* [[Information Awareness Office]]: 2002–2003
* The [[Advanced Technology Office (DARPA)|Advanced Technology Office (ATO)]] researched, demonstrated, and developed high payoff projects in maritime, communications, special operations, command and control, and information assurance and survivability mission areas.<ref>[https://www.militaryaerospace.com/communications/article/16709225/darpa-looks-to-ultrawideband-technology-for-advanced-tactical-networking/ DARPA looks to ultra-wideband technology for advanced tactical networking] 
 militaryaerospace.com. May 1, 2003</ref>
* The [[Special Projects Office (DARPA)|Special Projects Office (SPO)]] researched, developed, demonstrated, and transitioned technologies focused on addressing present and emerging national challenges. SPO investments ranged from the development of enabling technologies to the demonstration of large prototype systems. SPO developed 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 developed significantly more cost-effective ways to counter proliferated, inexpensive cruise missiles, UAVs, and other platforms used for weapon delivery, jamming, and surveillance. SPO invested 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 Office of Special Development (OSD) in the 1960s developed a real-time [[remote sensing]], monitoring, and predictive activity system on trails used by insurgents in Laos, Cambodia, and the Republic of Vietnam.  This was done from an office in Bangkok, Thailand, that was ostensibly established to catalog and support the Thai fishing fleet, of which two volumes were published.  This is a personal recollection without a published citation.  A report on the ARPA group under which OSD operated is found here.<ref>{{cite web |last1=Joanne |first1=Sandstrom |title=The United States and Thailand |url=https://digitalassets.lib.berkeley.edu/ieas/IEAS_12_0002.pdf |archive-url=https://web.archive.org/web/20210722140418/https://digitalassets.lib.berkeley.edu/ieas/IEAS_12_0002.pdf |archive-date=2021-07-22 |url-status=live |website=digitalassets.lib.berkeley.edu/ |publisher=Berkeley.edu |access-date=22 July 2021}}</ref> 
A 1991 reorganization created several offices which existed throughout the early 1990s:<ref>{{cite news| url=http://findarticles.com/p/articles/mi_6712/is_n27_v171/ai_n28601257/ | archive-url=https://archive.today/20120708012812/http://findarticles.com/p/articles/mi_6712/is_n27_v171/ai_n28601257/ | url-status=dead | archive-date=2012-07-08 | work=Defense Daily | title=DARPA restructures/creates new offices | year=1991}}</ref>
* The [[Electronic Systems Technology Office]] combined areas of the Defense Sciences Office and the Defense Manufacturing Office. This new office will focus on the boundary between general-purpose computers and the physical world, such as sensors, displays and the first few layers of specialized signal-processing that couple these modules to standard computer interfaces.
* The [[Software and Intelligent Systems Technology Office]] and the [[Computing Systems office]] will have responsibility associated with the Presidential High-Performance Computing Initiative. The Software office will also be responsible for "software systems technology, [[machine intelligence]] and software engineering."
* The [[Land Systems Office]] was created to develop advanced land vehicle and anti-armor systems, once the domain of the Tactical Technology Office.
* The [[Undersea Warfare Office]] combined areas of the Advanced Vehicle Systems and Tactical Technology offices to develop and demonstrate submarine stealth and counter-stealth and automation.

A 2010 reorganization merged two offices:
* The [[Transformational Convergence Technology Office|Transformational Convergence Technology Office (TCTO)]] and the [[Information Processing Techniques Office|Information Processing Techniques Office (IPTO)]] were combined in 2010 to form the [[Information Innovation Office|Information Innovation Office (I2O)]].
** TCTO's mission was to develop new crosscutting capabilities from a broad range of emerging technological and social trends, particularly in areas related to computing and computing-reliant subareas of the life sciences, social sciences, manufacturing, and commerce.<ref name="darpa.mil"/><ref>{{cite web |url=http://www.hpcwire.com/2010/09/22/embedded_clouds_a_look_back_at_hpec_2010/ |title=Embedded Clouds: A Look Back at HPEC 2010 |work=HPCwire |access-date=7 July 2015 |url-status=dead |archive-url=https://web.archive.org/web/20150707185535/http://www.hpcwire.com/2010/09/22/embedded_clouds_a_look_back_at_hpec_2010/ |archive-date=7 July 2015 |date=2010-09-22 }}</ref>
