Epirus
Critical-point-defense company centered on software-defined, solid-state high-power microwave systems for defeating drones and swarms.
The product
Leonidas high-power microwave systems, expeditionary and vehicle-mounted counter-UAS variants, RF test equipment, and supporting sensing, command-and-control, modeling, training, and sustainment capabilities.
The thesis
High-power microwave effects can counter multiple low-cost drones at once without expending a missile per target, addressing the unfavorable economics and saturation risk of drone swarms.
How it runs
Develops solid-state RF hardware and continuously tunable software, then integrates the systems into fixed, maritime, and manned or unmanned ground configurations with government and industrial partners.
How it earns
Government development, delivery, training, sustainment, and follow-on production contracts; test-equipment sales and integration partnerships. Commercial critical-infrastructure revenue remains less visible.
Why it wins
A solid-state, software-defined architecture designed for one-to-many effects and rapid waveform tuning, with operational integration across Army, Navy, Marine Corps, autonomous ground, and maritime contexts.
