Where the Future Becomes Now

The Defense Advanced Research Projects Agency was created with a national sense of urgency in February 1958 amidst one of the most dramatic moments in the history of the Cold War and the already-accelerating pace of technology. In the months preceding the official authorization for the agency’s creation, Department of Defense Directive Number 5105.15, the Soviet Union had launched an Intercontinental Ballistic Missile (ICBM), the world’s first satellite, Sputnik 1, and the world’s second satellite, Sputnik II… More

SEMATECH
1986
Beginning in 1987, the SEMATECH consortium received funding from the Federal Government to help revitalize the U.S. chipmaking industry. SEMATECH is an acronym that derives from Semiconductor Manufacturing Technology A decade after its founding, in 1997, the consortium was standing on its own without annual funding from the Government. It has since spawned other organizations, such as the International Semiconductor Manufacturing Initiative with a focus on manufacturing equipment and operations.
Microwave and Millimeter Wave Integrated Circuit (MIMIC)
1987

The Microwave and Millimeter Wave Integrated Circuit (MIMIC) program’s objective was, according to a review by one of its program managers, “to develop microwave/millimeter-wave subsystems for use in military weapon system ‘front ends’ that are affordable, available, and broadly applicable.” The program catalyzed multi-faceted research in materials (gallium arsenide), device design, integration, defect management, manufacturing, and other areas. The work yielded a new infrastructure for MIMIC technology with specific applications proliferating throughout the military and commercial sectors.

Phased-array radar systems were among the technology’s earliest uses for defense, but as the technology progressed toward greater yields and cost reductions, cell phone designers turned to MIMIC-based power amplifiers, which placed far more communications reach in smaller packages than ever before. The program provided foundations for follow-on technology development and has served as a model for subsequent programs for pushing microwave, millimeter-wave, submillimeter-wave and THz-frequency solid-state electronics forward. In 1993, The Space Foundation, citing DARPA’s pivotal role, inducted MIMIC Technology into its Hall of Fame.

Tank Breaker
1987
Beginning in the 1970s, DARPA began the Tank Breaker program in response to deficiencies identified by the U.S. Army and U.S. Marine Corps in their existing infantry anti-tank weapon. The Army evaluated two Tank Breaker designs by industry participants against alternatives in a shoot-off conducted in 1987-1988. The results led to selection of the Texas Instruments (later Raytheon) solution to the tank warfare challenge. Department of Defense officials approved it for full-scale development in 1989 under the Army’s Advanced Anti-armor Weapon System-Medium (AAWS-M) program. The Army later renamed the weapon Javelin, which entered full-scale production in 1997. It was the world’s first medium-range, one-man-portable, fire-and-forget anti-tank weapon system.
UAVs
1988
Under a joint program (Teal Rain) with the U.S. Navy, DARPA funded the development of the first endurance unmanned aerial vehicle (UAV), Amber, which in 1988 flew for more than 38 straight hours and reached an altitude of 25,000 feet. The Amber demonstration featured innovations in many technologies (digital flight controls, composite materials, microprocessors, and satellite navigation) and led to the Gnat 750 and the Tier 2 Predator. DARPA also supported development of the Global Hawk, a related high-altitude UAV system. These platforms have been transformative with respect to warfighting and ISR (intelligence, surveillance, and reconnaissance) capabilities.
Undermanned Undersea Vehicle
1988
Full-sized, staffed ships and other sea platform cannot perform safely in all Navy missions in near-shore, or littoral waters. These missions include mine location and avoidance as well as remote surveillance. In 1988, a joint DARPA/Navy Unmanned Undersea Vehicle (UUV) Program was initiated, with the goal of demonstrating that UUVs could meet specific Navy mission requirements. The program started with a memorandum of agreement between DARPA and the Navy that specified the design and fabrication of test-bed autonomous vehicles, the independent development of mission packages, and their subsequent integration. The Navy initially pursued a submarine-launched UUV that would either guide the submarine through an area that might be mined or search an area for mines. When the Cold War ended, however, the Navy revised the program with the objective of developing a tethered shallow-water mine reconnaissance vehicle for littoral warfare. The work in the UUV led to many follow-on projects, along with a range of technology developments. Even as the Agency enters its seventh decade, UUV R&D remains part of its portfolio.

High Definition Systems
1989
The High Definition Systems program was started in 1989 as the High Definition TV program. It was renamed High Definition Systems in 1990 and continued until 1993. The program supported work on display-related technologies, including materials and manufacturing techniques. One novel technology supported by the program, digital mirror projection technology, became a commercial success in electronic projectors, and led to an Emmy Award and an Oscar Technical Achievement Award.

RF Wafer Scale Integration
1989
The microelectronics revolution led to a ubiquity of fingernail-sized chips bearing integrated circuits made of large numbers of tiny transistors, interconnects, and other miniaturized components and devices. DARPA challenged the research community to achieve the tight integration of chips to the scale of the entire semiconductor wafer from which, normally, hundreds of chips would be diced and then packaged into separate components of electronic systems. Among the motivations were the expectations of higher computation or storage capability in a smaller volumes, higher-reliability systems; and reduced power consumption of the wafer-based systems. The research included work in materials, defect management, manufacturing techniques, among other areas. The approach opened up novel engineering opportunities particularly for fabricating multi-element, phased-array, antenna modules on gallium-arsenide wafer for both transmitting and receiving signals.
Taurus Launch Vehicle
1989
DARPA initiated a Small Standard Launch Vehicle (SSLV) program that led to the Taurus, a launch vehicle designed to supply the Department of Defense with quick-response, low-cost launch of tactical satellites from ground facilities. The initial DARPA model was first test-launched in 1989 and first used operationally in 1994. The prime contractor subsequently offered the vehicle in four versions.
Vertical-Cavity Surface-Emitting Lasers
1989
First proposed in 1977 by Japanese researcher Kenichi Iga, the vertical-cavity surface-emitting laser (VCSEL) would have characteristics similar to light-emitting diodes and could be coupled to optical fibers. Over the next decades, a small research community began chipping away at the technical challenges it would take to produce practical VCSEL devices. But not until 1989 when DARPA began a series of programs that would support, among other technology goals, the government-wide High Performance Computing and Communications (HPCC) Initiative, did the financial and institutional resources become adequate to move technical promise toward technological reality. VCSELs could provide short-distance, high-speed digital interconnections that would be important to meet goals of the HPCC initiative. One thrust of this effort led to the formation of the Optoelectronic Technology consortium, which led to an industry-stimulating demonstrating of multi-gigabit optoelectronic interconnect components that were based on VCSELs. At this point, still with some DARPA support, industry began to take the development baton. By 2000, VCSELs began to emerge from their developmental status into applications in fiber-fiber interconnections, optical data storage, and sensing applications. They later subsequent find roles in technologies, such as free-space chip-to-chip communications and atomic clocks, which were supporting or leading players in later DARPA programs.
Cermet Armor Material
1991

In addition to supporting advanced materials development since its early years, DARPA has at times been called upon to identify technologies for specific near-term applications. One of these tasks occurred for Operation Desert Storm (1991-1992) when ground forces experienced a critical need for more effective armor. The DARPA solution in this case, particularly for roof protection for the U.S. Marine Corps’ Light Armored Vehicles (LAVs) against artillery, was to ask the Lanxide Corporation to modify its cermet (ceramic/metallic) process and to work with a partner Foster Miller to produce appliqué armor.

From 1984 to 1986, DARPA supported the materials research and engineering that led to these cermet materials. With DARPA funding, 75 LAVs were up-armored with the tough composite materials. In the early 1990s, M-9 Armored Combat Earthermoves (ACE) also employed this lightweight armor. Variations of these cermet materials have been used for cockpit armor by the U.S. Air Force in C-130, C-141, and C-14 aircraft in Bosnia.

The Lanxide material has also been employed as high-power-density heat sinks for the F/A-18 and F-16 radars, turbine tip shrouds, commercial satellite heat sinks, very stiff parts for semiconductor lithography machines, and as vehicle brake components. All of the military and civil uses of Lanxide evolved directly from DARPA’s program. The military uses were under DARPA support, and then transitioned to U.S. Army and Air Force programs.

Interferometric Synthetic Aperture Radar – Elevation (IFSARE)
1991
In the early 1990s, DARPA developed an airborne, all-weather, radar-based mapping capability that generated maps of the terrain with an accuracy to within six feet of elevation and that could do so day or night, and in adverse weather conditions, such as thick cloud cover or rain. Under DARPA sponsorship, the Environmental Research Institute of Michigan (ERIM) carried out the project and mounted an interferometric radar system on a Learjet 36A to collect data, which was then processed on the ground into digital elevation models.
Affordable Short Takeoff Vertical Landing
1991

In 1983, DARPA began working with the U.K. Ministry of Defense (MoD) to develop a follow-on supersonic generation to the AV-8 Harrier, a pioneer aircraft for short takeoff and landing (STOL) capabilities. The international program that emerged from this intention, the Advanced Short Takeoff Vertical Landing (ASTOVL), expired in 1991, but various component efforts toward the same end continued. For its part, DARPA worked with the U.S. Navy to establish a development program for an STOVL Strike Fighter with capabilities specified by the Navy in 1988. The program evolved toward an aircraft that could build on much of the design base for the Air Force F-16.

In 1992, DARPA and the Navy initiated a revised ASTOVL program with an objective of demonstrating an affordable STOVL strike fighter for the U.S. Marine Corps with a conventional takeoff and landing version for possible U.S. Air Force service. In 1993 and 1994, this morphed into the DARPA-managed Common Affordable Lightweight Fighter (CALF) and into subsequent evolutionary incarnations managed by other Department of Defense entities.

Uncooled IR Detection
1991
DARPA proved that practical, uncooled infrared detector technology was possible under the Low Cost, Uncooled Sensor Program (LOCUSP) of the late 1980’s. Previous generations of IR sensors used cryogenics to cool the detector materials and reduce system noise. Although these steps proved to be effective – these earlier systems were credited with being a major factor in the U.S. ground victory in Desert Strom, for example – the sensors were costly to develop, prohibiting widespread distribution to combat troops. Under the LOCUSP program, cost-effective, uncooled IR detector technology was developed, fabricated, and demonstrated for use across various military applications. In 1991, the Uncooled Focal Plane Arrays (UCFPA) project was started under the Balanced Technology Initiative to create practical applications of DARPA’s research into uncooled sensor arrays. Under this effort, uncooled focal plane arrays were advanced for applications such as surveillance systems for perimeter defense and weapon sights.
Brilliant Anti-Tank Munition
1992
DARPA and the U.S. Army’s Fort Belvoir Research, Development and Engineering Center ran a series of concept studies in the early 1970s to define requirements for an anti-tank weapon referred to as the Terminally Guided Anti-Armor Indirect Fire Weapon System. Under DARPA’s wing, that morphed into the Brilliant Anti-Tank Munition (BAT)), a terminally guided anti-armor munition originally intended to be carried aboard the TriService Standoff Attack Missile. Its design featured dual seekers to minimize spoofing and a novel acoustic sensor that could cue on the sound of running tank engines. A decade after the program began, more than 1,100 pre-production and low-production units had been built.
Non-Penetrating Periscope
1992

In response to a call by Congress to establish a program to develop and efficiently transfer new hull, mechanical, and electrical technologies outside of normal U.S. Navy research and development channels, DARPA answered with the Advanced Submarine Technology (SUBTECH) program. Among ten technology demonstrations that successfully transitioned from the program to the Navy between 1989 and 1994 was the Non-Penetrating Periscope (NPP).

The NPP transformed submarine mast development when a prototype system using commercial visible and infrared spectrum cameras was built and demonstrated on the submarine USS Memphis in 1992. Using fiber optic data transmission, the new telescoping mast eliminated the need for the deep, hull-penetrating well that had been required to accommodate the optics tube on the then-current generation of submarines. The NPP also allowed greater flexibility in hull and interior design for future submarines.

DARPA becomes ARPA
1993
In character with President Clinton’s emphasis on economic growth, the Department of Defense restored DARPA’s original name, ARPA, to, in the words of a letter distributed by William Perry, then Deputy Secretary of Defense, “to expand the agency’s mission to pursue imaginative and innovative research and development projects having a significant potential for both military and commercial (dual-use) applications.” In 1996, the Agency again would pick up that D, for Defense, and become known once again as DARPA.
