Leonidas is a state-of-the-art, scalable HPM technology that has been tested by the US Department of Defense, proving its effectiveness in neutralising electronic threats. The system offers a revolutionary approach to modern warfare, capable of countering multiple threats simultaneously with a single operator.
The funding round was led by 8VC and Washington Harbour Partners LP, alongside returning investors such as StepStone Group, T. Rowe Price Investment Management, Gaingels, and strategic defence partner General Dynamics Land Systems. New investors, including Oppenheimer’s Private Market Opportunities Vista VI Fund, NightDragon, Manhattan Venture Partners, and Centaurus Capital LP, also contributed to the financing.
Epirus CEO Andy Lowery emphasised the importance of adapting to modern battlefield challenges, stating, “A new era of threats mandates a shift from a ‘1 to 1’ mindset to a ‘1 to many’ way of thinking for short-range air defence.” This funding will accelerate the manufacturing of Leonidas systems and support their deployment across various defence applications.
Joe Lonsdale, founder of 8VC, highlighted the system’s significance, describing Epirus’ directed energy technology as the “best protection against drone swarms today.” He also noted that future applications could extend to aircraft, ships, satellites, and space-based platforms, making it a key asset in future military strategies.
General Dynamics Land Systems (GDLS), a key partner, reaffirmed its support for Epirus, with GDLS President Dave Paddock stating, “We are excited to continue our strategic partnership and explore the potential of high-power microwave solutions in counter-UAS military applications.” The partnership will further integrate Leonidas™ technology into existing military defence systems.
Beyond military applications, Epirus envisions Leonidas becoming a core component of layered defence systems, protecting critical infrastructure such as military bases, borders, airports, and power plants. The company also sees potential for integration into next-generation military vehicles, aerial platforms, and helicopters.
To support its expansion, Epirus is set to open a new simulation centre in Oklahoma in Q3 2025. This facility will feature immersive training environments, including surround-sound audio, stadium seating, and agile training modules, ensuring operators can effectively deploy and manage Leonidas™ technology.
