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 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.

DARPA’s Tactical Undersea Network Architecture (TUNA) program recently completed its initial phase, successfully developing concepts and technologies aimed at restoring connectivity for U.S. forces when traditional tactical networks are knocked offline or otherwise unavailable. The program now enters the next phase, which calls for the demonstration of a prototype of the system at sea.

DARPA recently completed Phase 1 of its Gremlins program, which envisions volleys of low-cost, reusable unmanned aerial systems (UASs)—or “gremlins”—that could be launched and later retrieved in mid-air. Taking the program to its next stage, the Agency has now awarded Phase 2 contracts to two teams, one led by Dynetics, Inc. (Huntsville, Ala.) and the other by General Atomics Aeronautical Systems, Inc. (San Diego, Calif.).

The physical sphere of computers, home appliances, vehicles, cameras, and the ever-growing menagerie of handheld devices has become increasingly intertwined-by way of wireless connections to the internet-with the digital spheres of data and information. This expanding new technology arena brings with it vast opportunities for innovation, challenging and growing demand for access to the electromagnetic spectrum, and new vulnerabilities to ill-willed interference. Catalyzing interest and awareness in this cyber-physical intersection —and the development of new technology with an eye on both its promise and peril—is what program manager Tom Rondeau hopes his yearlong campaign, known as DARPA Software Defined Radio (SDR) Hackfests, will help to achieve.
