$250 Million Series D Funding

On March 5, 2025, Epirus announced the completion of an oversubscribed $250 million Series D fundraising round. This funding is aimed at expanding their production capabilities for directed-energy weapons, specifically targeting counter-drone technology. Following this round, Epirus has raised a total of over $550 million in funding, reflecting strong investor confidence and interest in their innovative approach to defense technology aimed at neutralizing drone threats.

Strategic Teaming Agreement with Peraton

Earlier, on February 27, 2025, Epirus unveiled a strategic teaming agreement with Peraton, focusing on a collaborative effort under a contract vehicle that has a ceiling of $48 billion. This partnership aims to leverage Epirus’ advanced energy solutions, including their Leonidas system, to enhance defense capabilities for both government and commercial applications.

Expansion and Production Plans

With the recent influx of capital, Epirus intends to enhance its production of high-power microwave technologies suitable for various defense applications. The company’s focus is not only on military use but also on potential civilian applications and international markets, reflecting a strategic move to broaden their market reach and applicability of their technologies.

Epirus continues to position itself as a leader in the defense tech startup space, seeking innovative solutions to emerging threats such as drone swarms, and their recent activities signify a strong growth trajectory supported by substantial investment.

On March 5, 2025, it was reported that the Series D funding round was led by 8VC and Washington Harbour Partners LP, with participation from several other notable investors including General Dynamics Land Systems and Gaingels. This further underscores the strategic importance and investor confidence in Epirus, especially as they aim to scale their Leonidas product line for both military and commercial markets, stating that their technology is already being recognized as the best protection against drone swarms today.

Furthermore, the company is looking to open a new simulation and training center in Oklahoma, which is expected to play a crucial role in training military personnel on counter-drone techniques and showcases their commitment to enhancing operational effectiveness.

Additionally, their strategic partnership with Peraton aims not only at improving existing defense systems but also at developing next-generation technologies that align with the future defense needs of the U.S. military, emphasizing the agile and innovative nature of Epirus’ operational model.
