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.

DARPA’s Extreme Accuracy Tasked Ordnance (EXACTO) program conducted the first successful live-fire tests demonstrating in-flight guidance of .50-caliber bullets. EXACTO rounds maneuvered in flight to hit targets that were offset from where the sniper rifle was aimed. EXACTO’s specially designed ammunition and real-time optical guidance system help track and direct projectiles to their targets during flight by compensating for weather, wind, target movement, and other factors that could impede successful hits.

Beginning in the mid-1970s, DARPA orchestrated extensive research into the semiconductor material gallium arsenide, which could host faster transistors operating at higher power than could silicon. The work would contribute to subsequent DARPA-spurred achievement in the 1980s to miniaturize receivers for GPS. That technology, in conjunction with DARPA-developed advances in inertial navigation, expanded the Nation’s arsenal of precision-guided munitions (PGMs) through such innovations as “bolt-on” Joint Direct Attack Munitions (JDAM) GPS kits, which gave otherwise unguided or laser-guided munitions new, high-precision capabilities. Key to these developments were gallium arsenide chips developed through DARPA’s Monolithic Microwave Integrated Circuit program, which also enabled the radio frequency (RF) and millimeter-wave circuits needed in precision weapons.

Early GPS receivers were bulky, heavy devices. In 1983, DARPA set out to miniaturize them, leading to a much broader adoption of GPS capability.

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.
