Innovative Semiconductor Manufacturing in Space: A Game Changer
As tensions escalate between the United States and China over Taiwan’s pivotal chip factories, a Welsh startup is garnering attention for its groundbreaking approach to semiconductor manufacturing in orbit. The vision is clear: to achieve an unparalleled quality of chips that cannot be replicated on Earth.
Understanding the Context
The geopolitics surrounding semiconductors present one of the most significant challenges for global powers today. In Europe, a staggering 80% of the chips required for various technologies are imported, with 90% of the most advanced ones sourced from Taiwan. Any escalation of conflict in this region could lead to catastrophic implications for global supply chains.

Interestingly, the answer to this complex problem may lie not on Earth but in space. This is where the innovative company Space Forge, headquartered in Cardiff, comes into play, aiming to utilize reusable satellites for manufacturing semiconductors and advanced materials beyond our atmosphere.
Manufacturing Chips in Space
But why venture to space for such small, yet essential components? The answer lies in physics . The vacuum and microgravity present in space provide ideal conditions for the creation of ultrapure crystals , the essential building blocks of any semiconductor. On Earth, gravity can introduce minor imperfections and defects in the crystalline structure of materials during their formation.
NASA has been examining the benefits of in-space manufacturing for decades. Gravity leads to phenomena like convection and sedimentation of molten materials, which hinder the homogenous distribution of components, generating defects. In space, these challenges vanish, allowing for the formation of materials that are more perfect, translating into higher quality chips that offer greater efficiency and consume less energy.
The First Satellite: An Achievable Milestone
Space Forge’s potential is underscored by its first manufacturing satellite , named Forgestar-1 , which was successfully launched in June 2025 aboard a SpaceX rocket. This satellite, developed entirely in Wales, is considered the first British spacecraft designed specifically for in-space materials production . Serving as a demonstration mission, it aims to confirm whether an appropriate manufacturing environment can be created and test various production techniques.
NATO’s Investment: A Vote of Confidence
In a significant achievement, Space Forge secured $30 million in its first funding round—making it the largest investment for a space technology company in the UK. The most notable contributor is the NATO Innovation Fund ( NIF ), which emphasizes the need for a long-term supply chain independence and resilience as a key reason for their investment.
This financial backing will accelerate the development of Forgestar-2 , the next generation of the company’s returnable manufacturing satellite. The mission underscores NATO’s focus on innovative technologies to enhance industrial capabilities.
Microgravity: The Future of Manufacturing
The applications of microgravity extend far beyond the realm of semiconductors. Potential innovations in metal alloys , which are difficult to mix on Earth, could prove beneficial. Moreover, the pharmaceutical industry stands to gain significantly, witnessing improvements in the shelf life of medicines and administration methods .
Microgravity as a Service
Space Forge envisions a business model termed “ microgravity-as-a-service ,” akin to the licensing model used by tech companies like Arm Holdings. Instead of merely selling chips, Space Forge plans to lease out spaces within its “orbital factories,” allowing other companies to produce their own advanced materials in microgravity conditions.
This model presents an innovative opportunity for various industries to leverage the advantages of space manufacturing. By reducing defects in material formation and improving efficiency, Space Forge could fundamentally shift how we approach technology production on Earth.
As the race for semiconductor supremacy continues, Space Forge’s efforts to establish a new paradigm for manufacturing could lead to a revolution in how these critical components are produced and utilized in technologies across the globe.
