About
About Epirus
Epirus develops software-defined, solid-state high-power microwave systems for counter-electronics and counter-UAS missions. Leonidas produces long-pulse electromagnetic effects intended to disable drones and other electronic systems without firing a finite supply of kinetic interceptors. Fixed and semi-fixed configurations can operate alongside radar, optical sensors and other weapons in layered short-range air defence.
The family also extends to vehicle-mounted and expeditionary forms, while Epirus Pod packages the technology for smaller platforms and specialised missions. Power management, gallium-nitride electronics and software-controlled waveforms let the company tune system performance and update effects through software. Leonidas-derived prototypes have been delivered to the U.S. Army, and later demonstrations have addressed large swarms and fibre-optic-controlled aircraft.

Timeline
Events
- 2026-10-05 - Contract Award - AeroVironment, Epirus, Kord and Boeing selected for JIATF-401 pilot
Selected systems are AeroVironment's P-HEL, Epirus' Leonidas, Kord's Firefly and Boeing's Compact Laser Weapon System. The evaluation will gather performance, cost, sustainment and operating-practice data in coordination with the FAA, U.S. Northern Command and the services. A separate December shoot-off at Dugway Proving Ground will assess additional laser and microwave candidates.
Source - 2026-08-10 - Contract Award - Epirus receives $11 million Marine Corps award for HAVOC
HAVOC packages Leonidas-derived high-power-microwave technology on a universal sled mount to protect mobile forces and forward assets from drone swarms. The Office of Naval Research manages the programme, which follows Epirus's earlier ExDECS delivery for Marine Corps evaluation. Epirus said the award includes a HAVOC system, testing, training and support; its facilities can support low-rate output of roughly one system per week.
