Epirus product offering
Product offeringCore offering
Epirus designs, develops, and manufactures software-defined high-power microwave (HPM) systems, anchored by its Leonidas family of products, that deliver counter-electronics effects against drones, drone swarms, and other electronic threats. The company also offers SmartPower, a software-based power management platform that uses AI/ML to dynamically allocate and optimize power across mission systems. Epirus primarily serves U.S. Department of Defense customers and allied international defense agencies.
Product overview
Epirus is a defense technology company built around a platform-plus-modules architecture centered on its SmartPower machine-intelligent power management platform and its flagship Leonidas family of solid-state, software-defined, long-pulse high-power microwave (HPM) systems. The core offering, Leonidas, is offered across multiple form-factor variants — including the portable Leonidas Pod, maritime Leonidas H₂O, expeditionary Leonidas Expeditionary and ExDECS, vehicle-mounted Leonidas VehicleKit, and the integrated platform products Stryker Leonidas (GDLS), Leonidas AR (GDLS TRX), and Leonidas AGV (Kodiak AI / Ford F-600) — which together provide layered short-range air defense, maneuver short-range defense, long-range HPM air defense, and compact electronic warfare capabilities. These are complemented by the Air Domain Awareness module (always-on UAS perception/tracking) and the Advanced Electronics module (hardware, software and AI capabilities for high-power applications). Underlying all products is SmartPower, which uses real-time machine intelligence and software-defined waveforms to deliver counter-electronics and counter-swarm effects across ground, air, sea, and space domains for government and commercial customers.

Epirus competitors and assessment
Company assessmentDirect peers
- Anduril Industries: Closest direct peer - venture-backed defense tech company building autonomous systems, counter-UAS, and command-and-control (Lattice) software. Anduril and Epirus have an active software integration partnership for C-UAS kill chains, and both compete in the same DoD counter-drone programs.
- Shield AI: Venture-backed defense tech company developing AI-piloted autonomous aircraft and counter-UAS solutions. Competes with Epirus in the same venture-backed defense startup ecosystem and DoD autonomous systems programs.
- Helsing: European defense AI company building software-defined defense capabilities including AI for autonomous systems and electronic warfare. Comparable venture-backed defense AI peer serving allied nations' asymmetric threat challenges.
- Dedrone: Counter-UAS specialist focused on detection, tracking, and identification of small drones. While Dedrone focuses on the detect/track layer of the C-UAS kill chain (similar to Epirus's Air Domain Awareness), it competes for the same DoD and allied counter-drone budgets.
- DroneShield: Counter-UAS solutions provider offering RF-based detection and soft-kill defeat capabilities. Competes directly with Epirus in the soft-kill counter-drone space and serves similar government and critical infrastructure customers.
Emerging players
- Fortem Technologies: Emerging counter-UAS player specializing in airspace awareness and interceptor drones for drone-on-drone defeat. Adjacent to Epirus in the counter-UAS space with a different defeat mechanism (kinetic interceptor vs. HPM).
Broad incumbents
- Palantir Technologies: Larger, publicly-traded data analytics and defense software company operating broadly across defense and intelligence. Palantir runs the Warp Speed Cohort 2 program in which Epirus participates, and both serve overlapping DoD customers in command-and-control.
- RTX (Raytheon): Legacy defense prime with established directed energy, electronic warfare, and counter-UAS programs. Epirus leadership team came from Raytheon, and RTX competes for the same DoD HPM and counter-drone contracts at a much larger scale.
- L3Harris Technologies: Major defense prime and strategic investor in Epirus (Series B). L3Harris has broader defense electronics and tactical radio portfolios but partners with Epirus on power efficiency for tactical radios, signaling overlapping technology interests.
Others
- General Dynamics Land Systems: Defense prime and Epirus' flagship platform integration partner for Stryker, TRX, and Leonidas AGV. While not a direct competitor (GDLS is a customer/investor), it is a peer in delivering integrated counter-UAS solutions to the DoD.
