🚨 The U.S. Navy is now testing Leonidas H2O — a high-power microwave (HPM) system engineered specifically for maritime operations, designed for deployment on both warships and small boats.

Compact, modular, and software-defined — it successfully disabled 40–90 HP outboard engines during live trials using directed electromagnetic energy.

Safe around fuel, munitions, and personnel.
Silent, precise, and scalable — this is the future of naval force protection.
