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.

Unveiled in March 2016, DARPA’s Spectrum Collaboration Challenge has reached an early milestone by choosing 30 contenders for the first of the three-phase competition, slated to culminate at the end of 2019 with a live match of finalists who have survived the two preliminary contests. In addition to 22 teams from academia and small and large companies, eight individuals have made it into the competition.

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.).

If human ears could hear the electromagnetic spectrum, the noise levels these days would be overwhelming. The skyrocketing use of wireless devices in military and civilian domains has created a complicated and cacophonous environment, filled with signals of widely varying frequency and amplitude and a menagerie of modulations. For warfighters trying to maintain critical communications links, interpret ambiguous radar returns, or defend against electronic warfare tactics, the ability to sort through that thicket of waveforms is essential—to identify where key signals are coming from, what kind of signals they are, and how best to send and receive information via the least contested spectral bands.

Today is the grand opening of the Colosseum. We are not referring here to the storied concrete Colosseum in Rome, which was completed in 80 A.D. and remains famous for its ancient gladiatorial spectacles. We are talking here about DARPA’s Colosseum, a next-generation electronic emulator of the invisible electromagnetic world. Though it resides in a mere 30-foot by 20-foot server room on the campus of the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, MD, the Colosseum is capable of creating a much larger, and critically important wireless world.
