Software-defined, high-power microwave (HPM) directed-energy weapon. Defeats drone swarms by frying onboard electronics. Multiple target engagement per pulse.
Drone Intelligence Assessment
Epirus has built the most operationally credible non-kinetic counter-drone capability in the US defence industrial base. The Leonidas platform addresses the strategic problem that conventional kinetic counter-UAS cannot solve cost-effectively: defeating saturating drone swarms at scale without expending one missile per target.
The directed-energy microwave architecture inverts the cost equation. A single Leonidas engagement can disable multiple inbound drones simultaneously, with no consumable munition cost per kill. This is the capability profile that the FY27 DAWG budget request anticipates the autonomous-warfare environment will require, and Epirus is the only publicly known US company shipping it at deployable scale.
The March 2025 Series D of $250 million, taking total venture funding past $550 million, reflects investor positioning ahead of the procurement cycle. The participation of General Dynamics Land Systems as a strategic investor is particularly significant. It signals that one of the largest US defence primes views Epirus's HPM technology as integration-grade for vehicle-mounted air defence rather than as an isolated point capability. As the counter-UAS segment compounds with the broader autonomous warfare procurement, Epirus is positioned as the directed-energy specialist most defence primes will need to either partner with or replicate.
