The Contested Space Domain In modern military operations, information dominance is paramount. Satellite communication systems play a critical role in maintaining beyond-line-of-sight (BLOS) connectivity, allowing widely distributed or forward-deployed units—such as special operations teams in remote theaters—to maintain constant contact with command centers and allied forces. These capabilities are not …

The End of Federated Systems For decades, military aircraft, ships, and land systems have been overloaded with a patchwork of dedicated sensors and antenna arrays. Each mission-specific system—radar dishes for targeting, electronic warfare (EW) arrays for jamming, SATCOM domes for communication, and SIGINT pods for interception—demanded its own physical aperture …

The Challenge: Securing Communications in the Age of Persistent Surveillance Modern military operations depend on communication networks that are not only secure but also invisible to adversaries. Traditional approaches to hidden networking—ranging from VPNs to Tor and custom-encrypted channels—have provided limited protection, but they rely on heuristic assumptions rather than …

The Quantum Countdown Has Already Begun Imagine a scenario unfolding in the shadows of global cyberspace: nation-state adversaries quietly harvesting encrypted data from defense contractors, financial institutions, and critical infrastructure operators. This strategy, known as “Harvest Now, Decrypt Later” (HNDL), involves stockpiling encrypted data today with the intention of decrypting …

The Obsolescence Crisis: A $125.6 Billion Time Bomb Across America’s military landscape, critical systems such as the F-15 fighter jets, Arleigh Burke-class destroyers, and Patriot missile batteries still depend on microelectronics designed decades ago—some dating back to the 1980s. Today, nearly 70% of U.S. defense systems contain obsolete electronic components. …
