Overview

• Epirus says its Leonidas high‑power microwave system was tested on August 26 at Camp Atterbury, Indiana, before U.S. Department of Defense officials, other agencies, and representatives from nine allied nations.
• The company reports a 100% success rate against 61 drones, capped by a single pulse that disabled a 49‑drone swarm with what it describes as low‑collateral electromagnetic interference.
• Demonstrated scenarios included selective targeting of one of two closely spaced drones and a precision intercept that dropped a drone into a pre-identified safe zone.
• Epirus highlights software-defined waveforms, Gallium Nitride–based hardware, and the ability to sustain continuous fire as differentiators for one‑to‑many counter‑drone engagements.
• The firm says its July 2025 Leonidas update more than doubles range and lethality versus the 2022 version, with public evidence so far limited to company-provided video and statements from the controlled event.
