Epirus is a defense technology company that develops high-power microwave systems for counter-drone defense.
Epirus offers the Leonidas family of software-defined solid-state high-power microwave systems for counter-UAS, counter-swarm, and counter-electronics missions.
Variants include fixed Leonidas, Leonidas Mobile, and Leonidas Pod with open API integration to FAAD C2 and allied air-defense networks.
The global counter-drone market is expanding rapidly as asymmetric aerial threats from unmanned systems become more accessible to adversaries.
Government demand for scalable, non-kinetic defense layers is driving investment in directed-energy and electronic-warfare solutions, with high-power microwave systems positioned as cost-effective swarm defense.
Epirus targets rising demand for scalable counter-drone defeat as adversary UAS production accelerates.
A March 2025 Series D round raised two hundred fifty million dollars to hyperscale Leonidas production for critical asset protection.
Epirus leverages gallium nitride semiconductor technology to deliver software-defined, solid-state high-power microwave systems with rapid target engagement capabilities.
Its Leonidas platform offers a lower cost-per-engagement profile compared to kinetic interceptors, with open command-and-control architecture enabling integration with existing defense networks.
Leonidas uses software-defined waveforms and GaN solid-state HPM to deliver lower size-weight-power than legacy microwave systems.
Epirus positions the platform for pennies-per-kill economics against mass-produced drones versus costly kinetic interceptors.
Epirus positions Leonidas as a lower cost-per-engagement alternative to traditional kinetic counter-drone systems, reducing operational expenditure through reusable directed-energy effects.
The company offers fixed, mobile, and pod form factors with open C2 integration, targeting government and enterprise customers seeking scalable swarm-defense capabilities without recurring munitions costs.
