Space: Europe´s Next Dual-Use Frontier

Satellites guide planes, track crops, and enable secure communications. They also underpin military operations and national sovereignty. As Europe rethinks its place in space, the question is clear: can it transform its civilian-first legacy into a model that secures both resilience and values?

 

Space has always been a dual-use domain. The same satellites that guide aircraft and ships, monitor forests and seas, and connect remote communities also provide secure communications, precision navigation, and strategic awareness. For decades, Europe approached this reality with a civilian-first mindset: flagship programmes such as Galileo and Copernicus were designed for public benefit, with security implications left largely implicit.

That posture is now harder to sustain. The war in Ukraine showed how commercial space services can shape operations on the ground, while rapid advances in launch, small satellites, and sensing have lowered barriers to entry. Major powers are investing heavily, treating space as critical infrastructure for both economic resilience and national security. Europe, meanwhile, has uncovered dependencies on foreign launch capacity, commercial imagery, and communications that sit uneasily with its ambition of strategic autonomy.

A shift is under way. New initiatives aim at secure connectivity, better space situational awareness, and closer ties between civilian and defence users. National space commands are expanding, and a new generation of European startups is entering the market. Yet fragmentation persists, and the policy vocabulary still trails technological reality.

This article asks whether Europe can turn its civilian-first heritage into a competitive advantage in a world where space is unavoidably dual-use. It examines what makes space unique, where Europe stands, what is at stake for autonomy and industry, and how a coherent European model could align civil, commercial, and defence needs without losing sight of European values.

 

1. Why Space is the Ultimate Dual-Use Domain

Few domains illustrate dual-use more clearly than outer space. The same systems that underpin daily civilian life also provide critical military capabilities.

• Navigation: GPS in the U.S. and Europe’s Galileo serve billions of civilian users, from smartphones to aviation. At the same time, they deliver secure and encrypted signals essential for military operations and critical infrastructure.
• Earth Observation: Copernicus is a cornerstone of climate monitoring, disaster response, and agriculture management. Yet its satellites and data services also support border surveillance, maritime security, and intelligence gathering.
• Communications: Satellite broadband enables digital inclusion and rural connectivity, but the same constellations provide secure communications for armed forces and emergency responders. The Ukraine war highlighted this duality vividly, as commercial satellite internet became a strategic lifeline.
• Launch and Access: Rockets that deliver scientific payloads or commercial satellites to orbit also provide states with independent access to space – a capability with clear defence implications.
• Space Situational Awareness: Tracking debris ensures the safety of satellites and astronauts, but also forms the foundation for protecting assets against hostile interference.

In each of these cases, the boundary between civil and military use is not just blurred but fundamentally artificial. The technologies are the same, the infrastructures overlap, and the users often draw from identical data streams. Space is therefore not only a textbook case of dual-use — it is perhaps the most inescapable one.

 

2. Europe’s Civil-First Legacy

Europe’s space policy has long been shaped by a deliberate choice to emphasise civilian benefit over military application. When the European Space Agency (ESA) was founded in 1975, it was established as a civil organisation, distinct from NATO’s defence-oriented activities and national military programmes. The idea was that space should be a field of scientific cooperation and peaceful use, not a platform for strategic competition.

This legacy carried through to Europe’s flagship space initiatives. Galileo, the EU’s global navigation system, was framed explicitly as a civilian alternative to the U.S. GPS. Its purpose was to guarantee Europe autonomous access to positioning and timing data for transport, energy, and communications infrastructure, while its secure military-grade service remained a secondary element. Copernicus, launched in the late 1990s, was designed as the world’s most ambitious Earth observation programme, focused on environmental monitoring, climate science, and disaster response.

These programmes demonstrated Europe’s ability to lead in space, but they also reinforced the division between civil and defence. Military space capabilities remained the domain of national governments, developed separately through defence budgets and largely outside EU coordination. As a result, Europe built powerful civil systems without integrating defence users or reaping the economies of scale that come from pooling civil, commercial, and military demand.

The consequence of this civil-first approach is a fragmented ecosystem. The EU and ESA lead in environmental and scientific space programmes; Member States operate their own defence satellites; and commercial actors are beginning to carve out niches. Yet the absence of a shared framework has meant duplication of effort, gaps in capability, and a weaker collective response to emerging geopolitical challenges.

 

3. The Geopolitical Wake-Up Call

The war in Ukraine has transformed how Europe views space. What was once seen primarily as an enabler of scientific progress and environmental monitoring has emerged as a cornerstone of national security and military operations.

Commercial providers played a decisive role. High-resolution imagery from private Earth observation satellites gave Ukrainian forces near real-time situational awareness. Starlink satellite internet became a vital communications lifeline when terrestrial infrastructure was disrupted (though it also exposed the risks of reliance on a single private actor). These contributions underscored how easily commercial, ostensibly civilian space assets could be repurposed in conflict — and how valuable they could be when speed and resilience mattered most.

At the same time, Europe became acutely aware of its own vulnerabilities. The continent remains dependent on U.S. GPS for navigation, on American launch providers such as SpaceX for access to orbit, and on foreign commercial providers for some of its imagery and communications needs. These dependencies sit uneasily with Europe’s ambition of strategic autonomy, particularly at a time when both the United States and China are accelerating the integration of space into their dual-use innovation ecosystems.

For Washington, space has long been a national security priority, backed by the Pentagon and NASA’s coordination with commercial space. In Beijing, civil and military space programmes are fused by design, with massive state-led investment in satellites, launchers, and space stations. China has rapidly become the West’s most formidable rival in orbit, fielding anti-satellite capabilities, building a permanent space station, and investing in mega-constellations that compete directly with U.S. and European initiatives. Its model demonstrates not only scale but also an uncompromising fusion of economic, technological, and military goals.

Against this backdrop, Europe’s civil-first posture looks increasingly out of step. Space is no longer a benign, cooperative domain; it has become a field of strategic competition where civilian, commercial, and defence interests converge. If Europe wants to safeguard its autonomy, it must treat space not as a secondary concern but as a core pillar of its security and industrial strategy.

 

4. Europe’s Emerging Shift

Europe is not standing still. Over the past three years, the EU and its Member States have begun to recalibrate their approach, slowly but unmistakably moving from a civil-first paradigm toward one that recognises space as a strategic, dual-use frontier.

The most visible sign is IRIS², the EU’s secure connectivity constellation launched in 2022. For the first time, Brussels has explicitly designed a flagship space programme with both civilian and security objectives. The system will provide encrypted communications for governments and critical infrastructure, while also serving commercial broadband markets — a clear acknowledgment that resilience in space must serve both citizens and armed forces.

The European Defence Fund has also opened a pathway for space-related defence research, with calls supporting areas such as space situational awareness, secure satellite communication, and protection of space infrastructure. Meanwhile, the European Space Agency and the European Commission are intensifying coordination, with new efforts to bridge the divide between ESA’s civil mandate and the EU’s security agenda.

At the national level, momentum is equally visible. France has established a Space Command and declared space a “military domain.” Germany and Italy are investing in new military satellites. Smaller Member States are also finding niches: Luxembourg has positioned itself as a hub for space finance, while Poland has expanded investment in space-based reconnaissance. Slovakia, too, is beginning to carve out a role, with promising advances at the Technical University of Košice and the opportunity to draw on Ukraine’s legacy as a hub of the Soviet space industry. This is not only about integrating skilled individuals but about leveraging deep technical know-how and industrial experience – assets that, with the right support, could help anchor a meaningful national contribution to Europe’s wider ambitions. A new generation of European startups, from launch services to in-orbit servicing and Earth observation, is entering the market, bringing commercial energy into a field long dominated by state actors.

What makes this shift particularly European is its emphasis on integration rather than militarisation. The emerging model is not about creating a Pentagon-in-space, but about ensuring that civil, commercial, and defence needs are met through shared infrastructure, open standards, and transparent governance. If successful, it could become a competitive advantage: a way to deliver security without abandoning Europe’s values of openness and cooperation.

Yet this shift remains fragile. Funding is fragmented, coordination between EU and national programmes is incomplete, and startups still face obstacles in scaling to global markets. Without greater clarity and investment, Europe risks missing the window to secure its place in the rapidly evolving space economy.

Still, the direction of travel is clear: Europe is beginning to treat space not just as a laboratory of science or a market for services, but as critical infrastructure for autonomy, resilience, and security.

 

5. What’s at Stake

The choices Europe makes in space policy over the next decade will shape far more than its presence in orbit. At stake are three interlinked priorities: strategic autonomy, industrial competitiveness, and technological resilience.

Strategic autonomy. Without secure access to space-based navigation, communications, and Earth observation, Europe cannot guarantee the independence of its security or foreign policy. Dependence on U.S. or commercial providers may be workable in peacetime, but in a crisis it leaves Europe vulnerable to decisions made elsewhere.

Industrial competitiveness. Space is not just a sector; it is an enabler of the wider economy. From logistics to agriculture, from disaster response to finance, countless industries rely on satellite services. If Europe fails to build competitive space industries, it risks ceding not only defence capability but also entire markets to U.S. and Chinese companies. Political uncertainty in the U.S. may also open unexpected windows. Shifting priorities in Washington, from fluctuating NASA budgets to questions about long-term commitment to civil space programmes, create both risks and opportunities. A disengaged United States could weaken transatlantic cooperation, but it could also allow Europe to attract talent, capture investment, and advance capabilities that might otherwise have remained dominated by Washington.

Technological resilience. Space infrastructure underpins both climate monitoring and cyber-physical security. Without European systems in place, everything from environmental modelling to critical infrastructure protection is exposed to external shocks. In a world of rising geopolitical competition, this resilience is as vital as decarbonisation or digitalisation.

The dual-use nature of space makes the stakes higher still. A satellite constellation is not just a scientific instrument or a commercial service; it is a potential security asset. A launch capability is not just an industrial achievement; it is a guarantee of sovereignty. Europe’s ability to integrate these realities without losing sight of its values will determine whether space becomes a source of vulnerability or a pillar of strength.

 

6. Europe’s Path Forward

If space is the ultimate dual-use frontier, Europe’s challenge is not to copy the models of others, but to design its own. The task is to reconcile civil, commercial, and defence needs in a way that reflects European values while closing the gaps that leave the continent vulnerable.

Three priorities stand out:

• Signal demand clearly. European startups and industries need certainty that their technologies will find buyers at scale. That requires joint procurement, coordinated EU-level programmes, and early adoption of new systems by public authorities. Without predictable demand, investment will remain hesitant.
• Help companies scale. Europe has strong research and promising startups, but too few make the leap to global competitiveness. Tailored financing from the European Investment Bank, the European Defence Fund, and national promotional banks could de-risk private capital and create the conditions for a vibrant NewSpace sector serving both civil and defence markets.
• Streamline governance. Space in Europe is still divided between ESA’s civil mandate, the EU’s industrial and security programmes, and national military systems. Greater integration — without new silos or duplicated institutions — is essential if Europe is to act with speed and credibility.

Above all, Europe must speak honestly about space as a dual-use domain. Pretending that satellites and launchers are “civilian only” no longer matches technological reality or geopolitical context. A European model should embrace transparency and accountability, but also accept that resilience and security are legitimate goals of space policy.

 

Conclusion

The Dual-Use Gap That Puts Europe at Risk  is nowhere clearer than in space. Europe has the scientific talent, the industrial base, and the political momentum to catch up, but only if it has the courage to break with old silos and the clarity to design its own model. The choice is no longer between civilian space and defence space, but between shaping the future of dual-use space on Europe’s terms or depending on others to do it.

If Europe can rise to this challenge, it will not only safeguard its autonomy but also strengthen its industry, its economy, and its societal resilience. More than a frontier, space will become a foundation — for security, for competitiveness, and for Europe’s place in the twenty-first century.
