Leonidas neutralized 61-of-61 drones, culminating in a 49-drone swarm kill with one pulse of electromagnetic interference

Los Angeles, Calif—September 10, 2025—Epirus announced today the results of an August 26 demonstration of the company’s Leonidas high-power microwave (HPM) system that delivers weaponized electromagnetic interference to counter swarms of robotic, asymmetric threats.
