Blue-green lasers are breaking the silence beneath the seas—enabling stealthy, high-bandwidth communication that is reshaping submarine warfare, autonomous systems, and the future of naval power. The Undersea Communication Dilemma Modern submarine operations are constrained by a long-standing limitation: radio frequency signals cannot effectively penetrate seawater. Acoustic communication systems, while useful …

Over-the-horizon radar is restoring strategic foresight, enabling nations to detect stealth aircraft, carrier groups, and hypersonic missiles thousands of kilometers beyond line-of-sight—before threats ever reach the horizon. Why Conventional Radars Fall Short Traditional microwave radars operate in straight lines, limiting their detection range to what is known as the radio …
