Leveraging the scalable Leonidas energy-based, high-power microwave technology platform, new maritime-based system demonstrated effectivity at record ranges against outboard boat motors at U.S Navy exercise.

Epirus announced today the introduction of Leonidas H2O, a, high-energy, high-power microwave (HPM) system developed to counter boat motors, unmanned surface vessels (USV) and unmanned aerial vehicles (UAV). The system is built using the scalable Leonidas energy-based, high-power microwave technology platform.

Leonidas H2O demonstrated effectivity against vessel motors at record ranges during the U.S. Navy’s Advanced Naval Technology Exercise Coastal Trident (ANTX-CT) program, during which the system was tested against four commercially available vessel motors ranging from 40 to 90 horsepower at a multitude of ranges.  

The Leonidas H2O prototype was successful against all four targets at operationally relevant ranges, despite range limitations which mandated testing occur at roughly half the maximum potential output power and with limited waveforms. The live fire demonstration was coordinated by Naval Surface Warfare Center Port Hueneme’s Office of Technology.

“The Department of Defense has spent years of research and development and poured tens-of-millions of dollars into developing a non-kinetic vessel stop solution, with no operational system deployed to date. With Leonidas H2O, we are bringing forth a proven technology with demonstrated effectiveness to fill this capability gap, today,” said Andy Lowery, Epirus CEO.  

“Epirus’ participation in these experiments helps to facilitate early eyes on leading edge technologies that are key to enabling the Navy’s mission and helps provide valuable resources to the project team in support of their own technical development and assessment,”added Brendan Applegate, ANTX-Coastal Trident program Principal Investigator.

Leonidas H2O leverages Epirus’ solid-state, software-defined, high-energy HPM technology platform that delivers unmatched counter electronics capabilities. Tested and proven as a scalable counter-swarm solution, all Leonidas variants boast an open architecture, unlimited magazine and demonstrated non-kinetic effects against a range of electronic threats. Epirus HPM technology emits non-ionizing radiation, ensuring Leonidas systems are safe for ordnance, fuel and personnel when properly managed.
