Today's dismounted squads use many different technologies to gather and share information. In many instances, however, these valuable but disparate inputs are not well integrated, leaving squad members without the degree of real-time situational awareness and support for decision-making that warfighters typically experience while on board aircraft and ships and in vehicles.

The U.S. military’s investments in unmanned aircraft systems (UAS) have proven invaluable for missions from intelligence, surveillance and reconnaissance (ISR) to tactical strike. Most of the current systems, however, require constant control by a dedicated pilot and sensor operator as well as a large number of analysts, all via telemetry. These requirements severely limit the scalability and cost-effectiveness of UAS operations and pose operational challenges in dynamic, long-distance engagements with highly mobile targets in contested electromagnetic environments.

Warfighters in aircraft, on ships and in ground vehicles have benefited tremendously from technological advances in recent decades, with advanced capabilities ranging from real-time situational awareness to precision armaments. But many of these benefits depend on equipment with substantial size, weight and power requirements, and so have remained unavailable to dismounted infantry squads who must carry all their equipment themselves.

Close air support (CAS)—delivery of airborne munitions to support ground forces—is difficult and dangerous because it requires intricate coordination between combat aircrews and dismounted ground forces (for example, joint terminal attack controllers, or JTACs). DARPA’s Persistent Close Air Support (PCAS) program focuses on technologies to enable sharing of real-time situational awareness and weapons systems data through approaches designed to work with almost any aircraft. PCAS envisions more precise, prompt and easy air-ground coordination for CAS and other missions under stressful operational conditions and seeks to minimize the risk of friendly fire and collateral damage by enabling the use of smaller munitions to hit smaller, multiple or moving targets.

State-of-the-art military sensors today rely on “active electronics” to detect vibration, light, sound or other signals. That means they constantly consume power, with much of that power and time spent processing what often turns out to be irrelevant data. This power consumption limits sensors’ useful lifetimes to a few weeks or months when operating from state-of-the-art batteries, and has slowed the development of new sensor technologies and capabilities. Moreover, the chronic need to redeploy power-depleted sensors is not only costly and time-consuming but also increases warfighter exposure to danger.
