Epirus Raises $250M to Expand Anti-Drone Defense Technology

The California-based startup plans to scale production, grow its workforce, and enter international and commercial markets.

Epirus secured $250 million in an oversubscribed Series D funding round led by 8VC and Washington Harbour Partners.
The company specializes in high-energy microwave systems for countering drones and drone swarms, with its flagship product, Leonidas, already in use by the U.S. Army.
General Dynamics Land Systems participated in the funding round, marking a strategic investment by a major U.S. defense contractor.
The funds will be used to expand into international and commercial markets, strengthen the supply chain, and open a new soldier training simulation center in Oklahoma.
Epirus has now raised over $550 million since its founding in 2018, positioning itself as a key player in the growing defense tech sector.
