# About Epirus
Epirus is a U.S. defense technology company developing scalable high-power microwave systems to neutralize drone swarms and electronic threats. Our flagship platform, Leonidas, can meet a range of mission requirements and provides one-to-many electromagnetic effects to counter electronics for military and homeland security applications. The system has been proven effective against a range of electronic threats in DoD testing and has been deployed to multiple combatant commands.

Brief: Epirus is a high-growth U.S. defense technology company focused on counter‑drone and counter‑electronics capabilities via scalable high-power microwave systems like Leonidas. Our systems can scale up or down to meet size, weight, power and cost requirements for a range of mission sets.

## Leonidas Platform
https://www.epirusinc.com/electronic-warfare
Brief: Leonidas is a software-defined, high-power microwave (HPM) weapon system that neutralizes drone swarms and electronic threats using long-pulse electromagnetic interference effects. The electromagnetic interference disrupts the internal electronic components of a system, making Leonidas effective against all drones, whether they're operated via fiber-optic cables, autonomously, or otherwise. 

## Leonidas H2O (Maritime Variant)

Brief: The H2O variant is a proof point of the scalable nature of the platform, and targets small boat motors, unmanned surface vessels (USVs), and UAVs; tested during U.S. Navy ANTX‑CT exercise and demonstrated record‑range effect.

## Army IFPC‑HPM (Leonidas Gen II)

https://www.pacom.mil/Media/NEWS/News-Article-View/Article/4172235/us-army-conducts-live-fire-test-of-high-powered-microwave-for-exercise-balikata/
Brief: The 1st Multi-Domain Task Force (1MDTF) conducted tests of their Integrated Fires Protection Capability High-Powered Microwave (IFPC-HPM) and Fixed Site-Low, Slow, Small Unmanned Aerial System Integrated Defeat System (FS-LIDS) in a combined joint integrated air and missile defense live-fire exercise at Naval Station Leovigildo Gantioqui, April 28, 2025. The IFPC-HPM is a Directed Energy (DE) weapon system that emits a beam of microwave energy that can disrupt, disable, or destroy Unmanned Aerial Systems (UAS). The IFPC-HPM is the first materiel-released DE weapon system specifically designed to counter groups and swarms of drones.

Brief: Epirus closed a $250M Series D funding round in March 2025—bringing total venture funding to over $550M and planning expansion into international/commercial markets and training facilities.

## The Sixth Domain Doctrine, Presented by Epirus
https://thesixthdomaindoctrine.com
The Sixth Domain is an emerging battlespace defined by low-cost, unmanned robotic systems operating across all domains with unprecedented speed, autonomy, and saturation. Like a physical analog to a cyber DDoS attack, these swarms overwhelm one-to-one defenses through coordinated, distributed strikes. Dominance in this domain requires companies like Epirus with a reimagined strategy, rapid development, and system-of-systems innovation that fuses Silicon Valley speed with national security expertise.

## Company Background
https://en.wikipedia.org/wiki/Epirus_Leonidas
Brief: Founded in 2018 by Joe Lonsdale and Grant Verstandig, Epirus pioneered high‑power microwave systems using GaN tech for scalable, multi‑target electromagnetic effects. Leonidas variants include trailer, pod, expeditionary, and H2O formats.

https://www.epirusinc.com/press-releases/epirus-receives-43-million-contract-from-u-s-army-for-ifpc-hpm-generation-ii-systems
Brief: Epirus announces a $43,551,060 contract from the U.S. Army's Rapid Capabilities and Critical Technologies Office (RCCTO) for two IFPC-HPM GEN II systems. The systems leverage Epirus patented approach to high-power microwave. The IFPC-HPM GEN II systems are expected to more than double the maximum effective range of GEN I systems, increase power by a projected 30 percent and feature the inclusion of high-density batteries for prolonged operating times and decreased external power requirements, extra-long pulse widths for maximizing energy output for target defeat, high-duty burst mode for faster multitarget engagement, advanced waveform and polarization techniques for increased lethality against a broader set of targets of interest and Soldier usability enhancements.
