The efficacy of nighttime aerial reconnaissance operations in Southeast Asia was diminished due to engine noise that provided the enemy with advanced warning of approaching aircraft. With an eye on making quiet aircraft that could better serve this reconnaissance mission, ARPA funded the Lockheed Missile and Space Company to develop a quiet, propeller-driven aircraft. This fast-paced program quickly yielded a successful prototype, the QT-2, which in 1968 was deployed and proven in combat. The program transitioned to the U.S. Army, which sponsored a limited production of an advanced version of the quiet aircraft, the YO-3A.

In what ended up being for the Agency an extremely rare practice of direct or near-direct support of active military operations, ARPA initiated Project Agile in 1961, which grew into a large and diverse portfolio of counterinsurgency research programs in Southeast Asia. The project ran through 1974. Along the way, subprojects included weapons (among them flamethrowers and what became known as the M-16 assault rifle), rations, mobility and logistics in remote areas, communications, surveillance and target acquisition, defoliation, and psychological warfare.

One of the first major efforts supported by ARPA's Information Processing Techniques Office (IPTO) was the Project on Mathematics and Computation (Project MAC), the world’s first large-scale experiment in personal computing, at the Massachusetts Institute of Technology (MIT). Orchestrated within the general context of broad-based command and control research suggested by the Office of the Secretary of Defense, and based on the vision of the founding IPTO Director, J.C.R. Licklider, Project MAC was oriented toward achieving a new level of human-computer interaction.

As part of the then three-year-old Quantum Information Science and Technology (QuIST) program, DARPA-funded researchers established the first so-called quantum key distribution network, a data-encryption framework for protecting a fiber-optic loop that connects facilities at Harvard University, Boston University, and the office of BBN Technologies in Cambridge, Mass.

New materials that perform better than previous ones or with unprecedented properties open pathways to new and improved technologies. F-15 and F-16 fighter aircraft, still in use by the U.S. Air Force today, owe much of their performance advancements to materials technologies that emerged from DARPA materials development programs conducted in the 1970s and early 1980s. One of many notable successes from these efforts was the development of rare-earth permanent magnets with magnetic strengths far stronger than conventional magnetic materials and, in some cases, over larger operational conditions. The samarium- and cobalt-based rare-earth magnetic material Sm2Co17, for example, remains reliable over the entire militarily relevant temperature range of -55°C to 125°C. These magnets ultimately assumed a role in a key component of the AN/ALQ-135 electronic warfare system, permitting operation of the F-15 to 70,000 feet in altitude.
