Huntington Beach, California-based defense manufacturer Mach Industries raised a $600 million Series C funding round led by Ribbit Capital and Sequoia, valuing the company at $3.7 billion, Crunchbase News reported. Mach develops unmanned aircraft, long-range weapons systems and propulsion technology.
The company said the funding will go toward building infrastructure to produce defense systems at scale, part of a broader wave of venture capital flowing into defense-technology manufacturing in 2026.
Why it matters: The scale of the round — among the largest for a pure defense-hardware manufacturer this year — reflects a broader shift in venture investment toward physical defense manufacturing capacity rather than purely software-based defense-tech, a trend with downstream implications for the unmanned-systems and counter-UAS markets this publication tracks closely.
