Though it is framed as an economic and technological strategy, the goals of Pax Silica -- a US-led initiative launched in December that is supported by 14 nations and other key global technology allies -- naturally extend to the space domain.

The expanding, multinational initiative aims to secure the global supply chain for silicon and critical elements essential to artificial intelligence (AI), semiconductor manufacturing and advanced technologies.

Space systems depend on semiconductors. Satellites, launch vehicles, ground stations and spacecraft rely on microelectronics that must function in austere environments and withstand radiation and oscillating temperatures.

As governments and private space companies expand satellite constellations and pursue lunar exploration, strategic priorities have shifted to focus on securing the supply chain behind key components.

Pax Silica seeks to secure supply chains related to critical minerals, energy, advanced manufacturing, semiconductors, AI infrastructure, and logistics.

It aims to reduce what the US State Department describes as "coercive dependencies" while protecting technologies considered essential to future economic and national security.

Coalition members include Japan, South Korea, Singapore, the Netherlands, the United Kingdom, Israel, the United Arab Emirates, and Australia.

On February 20, India joined the initiative, adding one of the world's largest technology markets and a growing semiconductor sector to the partnership.

Indian officials said membership would support the country's electronics, semiconductor and critical-minerals industries.

Supply chain security

US Under Secretary of State for Economic Affairs Jacob Helberg, who spearheaded the initiative, outlined the geopolitical logic behind it in his testimony before a House Foreign Affairs Committee hearing on February 24.

Helberg argued that technological competition has become a central arena of statecraft and warned against allowing hostile powers to exploit supply-chain chokepoints.

He said the initiative reflects a broader US effort to coordinate industrial policy, supply-chain security, and diplomacy among partners and allies.

With its need for advanced, mineral and chip heavy technologies, the space sector is a particular area of emphasis for Pax Silica.

It is difficult to repair spacecraft once they have been deployed. Components need to be structurally sound and reliable before launch. A compromised microchip can create vulnerabilities that persist throughout a mission's lifespan.

Hardware-level malware, counterfeit components, or production issues can affect satellite communications, navigation services, missile warning systems, and scientific missions -- potentially causing disruptions during critical moments.

The challenge is compounded by demand.

Governments and commercial operators are launching thousands of satellites to support communications, imaging, and data services, as everything from navigation systems to financial transactions leans on space-based infrastructure.

Each platform requires processors, sensors, memory devices and power-management systems. Many components depend on complex supply chains that span countries and continents.

Radiation-hardened semiconductors are one of the most critical links in that chain, as they are designed to operate in environments where conventional electronics may fail.

Yet production capacity remains limited, with only a handful of companies capable of manufacturing them that rely on specialized facilities, materials, and testing processes.

Any disruption can delay spacecraft production and deployment schedules.

Technological competition

Pax Silica aims to establish the foundation for future space infrastructure by securing access to semiconductor manufacturing, critical minerals and advanced industrial capacity.

Meanwhile, the Artemis Accords are promoting cooperation through a framework governing civil exploration of the moon and other celestial bodies, emphasizing transparency, interoperability, and coordination among participating nations.

At the same time, lunar programs led by China and Russia are advancing separate visions for exploration and infrastructure development.

While competition is often discussed in terms of competing visions for lunar bases or satellite networks, the reality is that it is unfolding at the industry level.

Access to trusted semiconductors, manufacturing capacity, and critical minerals will shape which countries can build and sustain large-scale space architectures over the coming decades.

In that sense, the technological competition referenced by Pax Silica on Earth parallels the geopolitical competition unfolding in orbit.

As governments invest in satellite constellations, lunar exploration and deep-space missions, the resilience of semiconductor supply chains may become as important as launch capabilities.
