Epirus Secures $250 Million in Funding to Combat Drone Threats
Torrance, California—Epirus, a defense technology startup, has successfully closed a $250 million Series D funding round, the company announced Wednesday. The investment will fuel Epirus’s efforts to ramp up production of its anti-drone weapons, reflecting a growing demand for such technologies.
The company did not disclose its valuation for this round. However, Epirus was previously valued at $1.35 billion during its Series C funding round, which raised $200 million.
This latest influx of capital comes as defense contractors are working to meet the surge in demand for advanced weaponry, particularly following the ongoing conflict in Ukraine.
“The cash infusion comes at a time when defense contractors are straining to meet the surge of demand for weapons following Russia’s invasion of Ukraine about three years ago.”
Epirus’s flagship product, Leonidas, secured a $66 million contract with the U.S. Army in 2023. Epirus is among a number of aerospace companies developing weapons that can neutralize unmanned aerial vehicles (UAVs) using both laser and microwave technologies.
The oversubscribed funding round was co-led by 8VC, a venture capital firm, and Washington Harbour Partners LP, an investment firm based in D.C. General Dynamics Land Systems, a tank manufacturing unit of the U.S. defense giant General Dynamics, also participated in the investment.
With this funding, Epirus’s total investments now exceed $550 million. The company plans to use the new funds to expand into international and commercial markets, consolidate its supply chain operations, and increase its workforce. In addition, Epirus will establish a new simulation center in Oklahoma to provide specialized training to soldiers in counter-drone warfare.
