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.

Modern airborne warfare is becoming increasingly complex, with manned and unmanned systems having to rapidly share information in a volatile environment where adversaries use advanced, commercially available electronic systems to disrupt U.S. and allied communications. Complicating the communications challenge for allied warfighters, many current airborne radio networks are incompatible with each other, the result of security and radio frequency (RF) format differences between aircraft types. Specialized data-link gateways facilitate communication across network divides, but these gateways have limited capability and don’t allow high-data-rate information to flow freely and seamlessly among multiple types of manned and unmanned aircraft.

DARPA has awarded a contract for the third and final phase of its Advanced RF Mapping program, known as RadioMap, which seeks to provide real-time awareness of radio spectrum use across frequency, geography and time. Akin to smartphone maps that show color-coded current traffic conditions, RadioMap is developing technology that visually overlays spectrum information on a map enabling rapid frequency deconfliction and maximizing use of available spectrum for communications and intelligence, surveillance and reconnaissance (ISR) systems.

DARPA today announced the newest of its Grand Challenges, one designed to ensure that the exponentially growing number of military and civilian wireless devices will have full access to the increasingly crowded electromagnetic spectrum. The agency’s Spectrum Collaboration Challenge (SC2) will reward teams for developing smart systems that collaboratively, rather than competitively, adapt in real time to today’s fast-changing, congested spectrum environment—redefining the conventional spectrum management roles of humans and machines in order to maximize the flow of radio frequency (RF) signals.

DARPA has awarded Phase 1 contracts for its Gremlins program, which seeks to develop innovative technologies and systems enabling aircraft to launch volleys of low-cost, reusable unmanned air systems (UASs) and safely and reliably retrieve them in mid-air. Such systems, or “gremlins,” would be deployed with a mixture of mission payloads capable of generating a variety of effects in a distributed and coordinated manner, providing U.S. forces with improved operational flexibility at a lower cost than is possible with conventional, monolithic platforms.
