$15M Deal Brings World-Class COPV Manufacturing In-House as SpaceX Scales Production for Starship and Orbital Infrastructure
Hexagon Purus ASA divests its aerospace subsidiary Masterworks Inc. to SpaceX for ~$15M. The acquisition gives SpaceX direct control over high-pressure composite storage cylinder manufacturing critical to its launch vehicles and emerging orbital infrastructure programs.

Hexagon Masterworks Inc. manufactures high-pressure composite storage cylinders for aerospace and space launch applications in North America. These are composite overwrapped pressure vessels (COPVs)—precision-engineered containers that store helium, nitrogen, and other pressurants at extreme pressures inside launch vehicles. COPVs are flight-critical hardware: they pressurize propellant tanks, operate pneumatic systems, and support life-support in crewed vehicles.
Hexagon Purus' parent technology platform (originally developed through Hexagon Composites) is considered world-class in Type 3 and Type 4 composite pressure vessel design. The company's cylinders are used across aircraft, launch vehicles, and spacecraft applications. Masterworks specifically serves the aerospace vertical, supplying high-pressure composite cylinders to launch providers.
SpaceX's defining operational philosophy is vertical integration. The company manufactures engines (Raptor, Merlin), avionics, structures, and even the silicon for its Starlink satellites in-house. This acquisition extends that philosophy to composite pressure vessels—a component category where SpaceX has historically relied on external suppliers.
The timing is strategic. SpaceX is scaling on multiple fronts simultaneously:
This is a textbook SpaceX vertical integration play. The $15M price is trivial relative to SpaceX's ~$350B valuation—effectively a rounding error. But the strategic value is asymmetric: SpaceX gains a proven manufacturing platform with established processes, quality certifications, and experienced personnel. Building this capability from scratch would take years; acquiring it takes months. For institutional allocators tracking SpaceX's supply chain maturation, this signals preparation for a significant production scale-up.
For Hexagon Purus, this divestiture is part of an ongoing portfolio review. CEO Morten Holum noted the aerospace business "has developed well in recent years and has now reached a stage where an industrial owner with a dedicated aerospace focus is deemed to best support its future." The company simultaneously acknowledged that the North American hydrogen mobility market does not represent significant near-to-medium term potential.
The transaction strengthens Hexagon Purus' balance sheet and extends its liquidity runway—critical for a company navigating the slow ramp of hydrogen infrastructure adoption. Masterworks' existing hydrogen customer contracts are being transferred to other Hexagon Purus entities prior to closing, ensuring the parent company retains its core hydrogen business.
Hexagon Purus trades on the Oslo Stock Exchange (HPUR.OL) with a market cap of approximately NOK 1.5B (~$140M). The divestiture proceeds represent approximately 10% of the company's market capitalization—material for the seller even if immaterial for the buyer.
This acquisition fits a broader pattern of launch providers vertically integrating their supply chains as production scales. Rocket Lab has similarly brought composite manufacturing in-house. As launch cadence increases industry-wide, the suppliers of flight-critical components become strategic assets rather than commodity vendors.
OED tracks over 3,000 suppliers in SpaceX's extended supply chain. Each acquisition like this removes a node from the external network and brings it into SpaceX's vertically integrated production system. For remaining independent space suppliers, the strategic implication is clear: as launch providers scale, they will increasingly acquire rather than contract for critical components.
For allocators tracking the orbital data center thesis (see OED SIA No. 1), this acquisition provides a minor but confirmatory data point. SpaceX is not merely filing regulatory applications—it is building the manufacturing supply chain required to execute at scale. Owning COPV production is a necessary precondition for producing satellites and orbital infrastructure modules at the volumes implied by the FCC filing.
