Missions in remote, forward operating locations often suffer from a lack of connectivity to tactical operation centers and access to valuable intelligence, surveillance, and reconnaissance (ISR) data. The assets needed for long-range, high-bandwidth communications capabilities are often unavailable to lower echelons due to theater-wide mission priorities. DARPA’s Mobile Hotspots program aims to help overcome this challenge by developing a reliable, on-demand capability for establishing long-range, high-capacity reachback that is organic to tactical units. The program is building and demonstrating a scalable, mobile millimeter-wave communications backhaul network mounted on small unmanned aerial vehicles (UAVs) and providing a 1 Gb/s capacity.

In the heat of battle, lives can depend on being able to coordinate troop positions safely while directing aircraft to provide close air support for ground forces. DARPA’s Persistent Close Air Support (PCAS) program aims to help overcome those challenges by providing warfighters with advanced digital tools for situational awareness and targeting in place of legacy communications systems and traditional paper maps.

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.

For decades, U.S. military air operations have relied on increasingly capable multi-function manned aircraft to execute critical combat and non-combat missions. Adversaries’ abilities to detect and engage those aircraft from longer ranges have improved over time as well, however, driving up the costs for vehicle design, operation, and replacement.

DARPA recently demonstrated its Persistent Close Air Support (PCAS) prototype system on an A-10 Thunderbolt II attack aircraft, marking the system’s debut on a U.S. Air Force platform. The tests, which involved 50 successful sorties near Nellis Air Force Base in Nevada, showed that a warfighter serving as a joint terminal attack controller (JTAC) on the ground could, in seamless coordination with a pilot, successfully command an airstrike with as few as three clicks on a tablet.
