Defense tech startup Epirus has raised a massive $250 million to scale up its anti-drone weapon production, marking a major milestone in modern warfare technology.
Epirus’ Big Funding Win
Epirus, a defense technology startup specializing in anti-drone weapons, has successfully raised $250 million in a Series D funding round. While the company has not disclosed its latest valuation, it was previously valued at $1.35 billion after raising $200 million in its Series C round.
This latest funding comes at a time when the demand for advanced defense technology is soaring. Russia’s invasion of Ukraine has led to an increased need for weapons and counter-drone solutions, with global military forces racing to secure next-generation defense tools.
A Growing Demand for Anti-Drone Weapons
As drones become an integral part of modern warfare, governments and defense organizations are investing heavily in counter-drone technology. Epirus’ flagship product, Leonidas, is a directed energy weapon designed to disable enemy drones using powerful microwaves. The U.S. Army has already recognized its potential, awarding Epirus a $66 million contract in 2023 to supply Leonidas systems.
With this new funding, Epirus aims to scale up production, ensuring that military and security forces have access to cutting-edge defense systems capable of neutralizing drone threats.
Key Investors Betting on Epirus
The Series D funding round was oversubscribed, demonstrating strong investor confidence in Epirus’ technology and market potential. The round was co-led by venture capital firm 8VC and Washington Harbour Partners LP, a Washington D.C.-based investment firm. Notably, General Dynamics Land Systems, a unit of U.S. defense giant General Dynamics (GD.N), also participated in the round.
Epirus’ total funding now exceeds $550 million, positioning it as a key player in the defense industry’s shift toward next-gen warfare solutions.
What’s Next for Epirus?

With this fresh infusion of capital, Epirus plans to expand its market reach beyond the U.S. military. The company aims to enter international and commercial markets, strengthen its supply chain, and grow its workforce. Additionally, Epirus is set to open a new simulation center in Oklahoma, where soldiers will be trained in counter-drone warfare using its advanced technology.
The move signals Epirus’ ambition to dominate the anti-drone defense sector, an area that is becoming increasingly critical as nations seek to protect their airspace from evolving threats.
The Future of Drone Warfare
The rise of drone warfare has reshaped military strategies worldwide. Countries are now prioritizing investments in counter-drone systems to safeguard their assets and personnel. With its innovative approach to directed energy weapons, Epirus is well-positioned to lead this revolution in modern defense.
As the global arms race intensifies, companies like Epirus will play a crucial role in shaping the future of military technology. This $250 million investment ensures that Epirus remains at the forefront of the battle against unmanned aerial threats.
