About the Company

Mach Industries

Develops unmanned military systems and propulsion

Mach Industries designs and builds unmanned military systems, including VTOL drones, long-range strike weapons, and counter-UAS, along with propulsion and energetics. Its products combine flight hardware, power plants, and munitions into compact, military-ready systems, with most components produced in-house to lower costs. The company differentiates itself through vertical integration, a large California manufacturing footprint, and acquisitions (like Exquadrum) to expand solid-rocket-motor capability and reduce bottlenecks. Its goal is to scale manufacturing and accelerate programs to meet defense contracts and national security needs, supported by large funding rounds to grow production and operations.
