Mach Industries, a manufacturer of uncrewed defense systems, yesterday said it has raised $300 million in Series C funding. This brings the company’s total funding to $1.8 billion since it was founded in 2023.

“Today’s Series C funding is a powerful accelerator for our mission,” said Founder and CEO Ethan Thornton. “We’re delivering advanced unmanned systems at the pace the threat environment demands, and we’re grateful to our investors for believing in our ability to strengthen American and allied superiority on the battlefield.”

Founded in 2023, Mach Industries develops autonomous defense systems and the infrastructure to scale their production. By vertically integrating weapons, propulsion, and manufacturing, The Huntington Beach, Calif.-based company said it “delivers the speed, adaptability, and resilience required to preserve the allied edge in an increasingly contested world.”

Mach Industries said it aims to build next-generation systems that preserve an allied American technological edge. As drone warfare accelerates and adversaries field autonomous systems at scale, the company asserted that superiority will belong to those who can develop, manufacture, and deploy faster.

Mach recently acquired Exquadrum , now rebranded as Mach Energetics, integrating its energetics systems, engineering team, manufacturing infrastructure, and test facilities. The company said the acquisition enhances testing throughput and enables faster iteration across all platforms, advancing its long-term strategy to build more independent and resilient development and production.

The latest funding will enable Mach Industries to accelerate its execution of government contracts, acquire talent, develop products, and expand its Forge manufacturing network. To support this next phase of growth, the company has strengthened its executive team with senior technical, operational, and government engagement leaders to help drive system development, manufacturing scale, and long-term strategic initiatives.

The capital will also expand Mach Propulsion, advance second-generation systems, and deepen partnerships with U.S. Department of War customers, including the Army, Air Force, and SOCOM, as well as allied governments, it said.

Infinite Capital and Ribbit Capital led the round. The new investors join longstanding backers including Bedrock Capital, Sequoia Capital, and Khosla Ventures, an investor group that has supported Mach Industries across multiple stages of its growth.

“Mach will be vital to the safety and future of free societies,” said Nathan Doctor, founder of Infinite Capital. “As an outlier in defense innovation, Mach has proven with unprecedented speed to flight, production trajectory, and contract success that rebuilding America’s industrial base is of prime importance. The team’s mission-first ethos drives this strategy with urgency and operational discipline.”
