Company Description

Epirus is a technology company founded in 2018 that develops software-defined directed energy systems. Headquartered in Torrance, California, the company's primary offering is Leonidas, a high-power microwave (HPM) platform designed for electronic warfare and to counter unmanned aerial systems (UAS). The system utilizes artificial intelligence and intelligent power management for applications in the defense, security, energy, and communications sectors. Since its founding, Epirus has raised $144.7 million in total funding and had a market valuation of $1.4 billion as of February 2022.

Looking ahead, Epirus is scheduled to participate in multiple technology demonstrations, including a U.S. Department of Homeland Security event in the summer of 2025 and a live-fire test in December 2025 to showcase its system's ability to defeat fiber-optic guided drones. Recent announcements include a partnership with Singapore's Defence Science & Technology Agency to expand its presence in the Indo-Pacific and a collaboration with L3Harris Technologies to integrate an imaging system with its HPM platform. The company also recently demonstrated the defeat of a fiber-optic controlled UAS and appointed defense industry executive Stu Shea to its Board of Directors.
