The Huntington Beach-based defence startup Mach Industries has completed a $50 million cash-and-equity acquisition of Exquadrum to secure direct control over its rocket motor supply chain. CEO Ethan Thornton confirmed on 19 May 2026 that the deal brings all 85 employees from the solid rocket motor (SRM) specialist into the fold, rebranding the entity as Mach Energetics. The acquisition addresses a critical bottleneck in the American industrial base, where lead times for propulsion systems currently stretch into years due to market consolidation.
By absorbing Exquadrum, Mach Industries secures a 70,000-square-foot facility in Victorville, California, which includes a dedicated test site for rocket propulsion and energetics. This physical infrastructure allows the three-year-old firm to bypass the established duopoly of Aerojet Rocketdyne and Northrop Grumman. As modern drone warfare drives up demand for high-volume munitions, internalising motor production has become essential for startups aiming to scale without relying on legacy contractors.
Mach Industries reports that the deal will improve unit economics across its five core vehicle programs: Viper, Glide, Stratos, Dart, and Forge. Controlling the production of energetics is a strategic move to stabilise
infrastructure reliability within its own manufacturing pipeline. The company plans to enter production on at least three of these platforms this year, leveraging its new in-house propulsion expertise to meet Department of Defense requirements.
Securing vertical integration in the missile supply chain
Founder Ethan Thornton, who left the Massachusetts Institute of Technology (MIT) at age 19 to start the venture, maintains that vertical integration is no longer optional for defence hardware manufacturers. High costs and poor availability of independent SRMs have slowed innovation across the sector. By owning the IP and the production lines, Mach Industries can iterate faster than competitors tied to the delivery schedules of major prime contractors.
The deal originated from a chance encounter at an MIT recruiting event last September, where a recruiter heard an Exquadrum customer mention the firm’s specific propulsion capabilities. Mach Industries initially engaged as a customer before outbidding eight other potential buyers to acquire the company outright. Beyond internal use, Mach Energetics will sell components and testing services to other firms, positioning itself as a foundational supplier for the wider
industrial connectivity and defence ecosystem.
This expansion mirrors recent Pentagon efforts to diversify the supply base. In February, the US Department of Defense awarded Anduril $43.7 million to expand domestic SRM production, citing a “critical bottleneck” in munitions manufacturing. Mach Industries is now positioning its Victorville hub as part of a decentralised solution to these capacity constraints, offering the military an alternative to traditional, centralised production models.
Strategic alignment of the Mach Industries flight portfolio
The acquisition specifically supports the “Forge” network, which Mach Industries describes as its distributed manufacturing system. Unlike traditional factories, Forge is designed to be a flexible, scalable production network capable of generating revenue from allied nations and other defence manufacturers. This model integrates with the company’s autonomous weapons systems, such as the Viper—a jet-powered VTOL UAV with a range of 290 kilometres and a unit cost reportedly under $100,000.
Other platforms in the portfolio benefit from the propulsion and sensor integration now handled in-house. This includes Glide, a high-altitude glide bomb, and Stratos, an ultra-high-altitude balloon platform designed to operate above 60,000 feet. By controlling the energetics, Mach Industries can standardise parts across these diverse systems, a common challenge in
industrial and engineering sectors where bespoke components often drive up costs and assembly times.
Integrating Exquadrum co-founders Kevin Mahaffy and Eric Schmidt into leadership roles within Mach Energetics ensures technical continuity. The combined workforce now totals approximately 350 employees. This bolstered engineering team will oversee the launch of “Venom,” a prototype flight demonstration aircraft developed in partnership with Divergent Technologies earlier this year, which utilises 3D-printed structures and Mach’s baseline avionics architecture.
Capital deployment and the path to scale
To fund this expansion, Mach Industries has raised a total of $185 million across three funding rounds as of February 2026. Its capital journey began with a $5.7 million seed round in June 2023, followed by a $79 million Series A that valued the firm at $335 million. The most recent infusion was a $100 million Series B round, which closed on 17 June 2025 and established a post-money valuation of $470 million.
The $50 million investment in Mach Energetics represents a significant allocation of this capital toward hardware sovereignty. By owning the “stack”—from the physical rocket motors to the flight software—the company remains insulated from the supply shocks that frequently disrupt traditional aerospace firms. This focus on domestic manufacturing capability is a response to the “unmanned era” of defence, where speed and attrition resistance are the primary metrics of success.
While Mach Industries operates primarily within the US defence sector, the move toward distributed, low-cost manufacturing has clear parallels for emerging industrial regions. As African nations increasingly look toward domestic production and industrial autonomy, the Mach model of high-value, small-footprint manufacturing hubs offers a template for building sophisticated hardware outside of classic industrial centres. For now, the successful integration of Mach Energetics will determine if the firm can deliver on its promise to produce high-performance munitions at a fraction of the traditional cost.
