Exquadrum

Exquadrum was acquired by Mach Industries in May 2026 for $50 million, addressing one of the most acute supply-chain bottlenecks in US defence: the collapse of domestic solid-rocket-motor production to just two suppliers, Aerojet Rocketdyne and Northrop Grumman, leaving tactical munition programmes facing seven-to-ten-month lead times. Mach outbid more than eight rival acquirers. All 85 Exquadrum employees joined Mach, along with the company's intellectual property and a 70,000-square-foot production facility anchored by an energetics and rocket propulsion test site in Adelanto, California. The business was rebranded Mach Energetics with a new commercial division selling rocket motors to external customers .

Founded in 2002 by Kevin Mahaffy and Eric Schmidt, both former Air Force Rocket Propulsion Laboratory engineers, Exquadrum spent over two decades working more than 70 contracts in solid rocket motors, controllable solid rockets, divert and attitude control systems, and counter-WMD munitions. Mahaffy was the Laboratory's former Chief of the Solid Rocket Motors Branch; Schmidt oversaw refurbishment of the test stands once used for Saturn V engines. The company chose Adelanto, California for its campus due to cost-effective real estate and a business-friendly city government.

Exquadrum's absorption into Mach is emblematic of the broader consolidation in US defence propulsion: a specialist firm with two decades of SBIR-funded innovation that could not scale through commercial markets alone, absorbed by a venture-backed startup with the capital and production ambition to industrialise its technology. The 70,000-square-foot Adelanto facility and test range give Mach a hardware moat that purely software-heavy rivals cannot replicate quickly.
