TLDRs;
- SpaceX signs decade-long $1.05B deal with Korea’s Sphere Corp for high-performance rocket alloys.
- Deal signals SpaceX’s shift from in-house manufacturing to strategic outsourcing of specialized materials.
- FAA approval to increase Starship flights pushes SpaceX to scale supply partnerships.
- Sphere’s Tier 1 status reflects rare capability in aerospace superalloys amid rising space sector demand.
SpaceX has entered a $1.05 billion supply agreement with South Korea’s Sphere Corporation, a move that underscores the evolving dynamics of the aerospace supply chain.
The decade-long deal, which runs through 2035 with an optional three-year extension, will see Sphere provide aerospace-grade nickel and superalloys essential for rocket engines and launch vehicle components.
Sphere, which became a Tier 1 supplier for SpaceX in 2023, will deliver $55.48 million worth of materials in 2026 alone. The company noted that volumes may grow as SpaceX increases its Starship launch cadence following regulatory approval from the U.S. Federal Aviation Administration (FAA).
Shift to Strategic Outsourcing
SpaceX, long known for its vertically integrated production model, is now strategically outsourcing components that require ultra-specialized manufacturing.
Historically, the Elon Musk-led firm prided itself on in-house production, helping control costs and accelerate innovation. However, as its operations scale, the company is pivoting toward selective outsourcing, particularly for components that demand rare materials and certification-intensive processes.
The Sphere deal represents this shift. Rather than diverting internal resources to create high-precision superalloys, SpaceX is opting to rely on vetted external partners, freeing up capacity to focus on core innovation areas such as rocket reusability, in-space manufacturing, and interplanetary logistics.
Sphere Enters Elite Aerospace Alloy Circle
The aerospace-grade alloy sector is highly exclusive, with just five Tier 1 suppliers globally capable of meeting the stringent performance and certification standards required for spaceflight.
These materials must endure temperatures above 2,000°F and withstand intense structural stress in rocket engines and nozzles.
Despite being lesser-known internationally, Sphere’s ability to land a $1 billion deal suggests its technological and quality credentials are on par with global leaders. The company’s status as a trusted vendor for SpaceX marks a significant milestone in South Korea’s emerging aerospace sector.
SpaceX Growth Spurs Supply Chain Expansion
SpaceX’s growing demand for materials is fueled not just by its Starship expansion but also by its broader ambitions in orbital manufacturing.
The company is working on “Starfall,” a new program to deploy capsules for microgravity-based manufacturing in pharmaceuticals, semiconductors, food, and cosmetics.
As the global space economy is forecast to hit $1 trillion by 2030, SpaceX’s proactive supply deals reflect its need to lock in capacity and reliability ahead of surging demand. In this context, the Sphere agreement isn’t just a purchase order, it’s a strategic move to future-proof SpaceX’s supply lines in a rapidly industrializing low-Earth orbit.
