Securing the High Ground: How Europe’s Militaries Are Adapting to the Contested Space Domain

The militarization of Earth’s orbit is no longer a theoretical scenario for science fiction writers or a distant concern for strategic planners. Today, space is recognized as a contested operational domain where geopolitical rivalries are actively playing out. From the jamming of Global Positioning System (GPS) signals in Northern Europe to the deployment of sophisticated anti-satellite (ASAT) technologies, the threats facing Western space assets are growing in both frequency and severity.

At the "Small Sat Europe" conference held in Amsterdam, SpaceNews hosted a panel on its defense stage to address a critical question: How should Europe’s militaries respond to space threats?

Led by SpaceNews journalist Emma Gatti, the panel brought together military strategists, defense analysts, and industrial experts to dissect Europe’s current defense posture, identify vulnerabilities, and chart a path forward. The discussion, recorded as a special episode of the Space Minds podcast, highlights a continent at a geopolitical crossroads, striving to balance national sovereignty with collective defense in an increasingly hostile orbital environment.


Chronology of Vulnerability and Awakening: The Road to Space Defense

To understand Europe’s current defense posture, one must trace the rapid escalation of space-based threats and the corresponding shift in European security policy over the last decade.

  • November 2019: NATO Declares Space an Operational Domain
    Recognizing that space is essential to modern warfare—supporting navigation, communications, intelligence, and early warning systems—NATO officially declared space its fifth operational domain, alongside land, sea, air, and cyber. In the same year, France established its specialized Space Command (Commandement de l’Espace), signaling a shift toward active defense.
  • November 2021: The Russian ASAT Test
    Russia conducted a direct-ascent anti-satellite (DA-ASAT) missile test, destroying its defunct Cosmos 1408 satellite. The destruction generated more than 1,500 pieces of trackable debris, threatening international assets in Low Earth Orbit (LEO) and demonstrating a kinetic willingness to disrupt orbital operations. This event accelerated the establishment of the UK Space Command and Germany’s Weltraumkommando.
  • February 2022: The Viasat Cyberattack
    On the eve of Russia’s invasion of Ukraine, a massive cyberattack targeted Viasat’s KA-SAT network. The attack successfully disabled thousands of satellite modems across Europe, disrupting Ukrainian military communications and accidentally knocking out wind turbines and civilian internet access in Germany and neighboring countries. This proved that commercial space infrastructure is a primary target in modern conflict.
  • March 2023: The EU Space Strategy for Security and Defence
    The European Commission released its first-ever dedicated space defense strategy. The document emphasized the need to protect EU space assets, enhance resilience against cyber and electronic threats, and foster a robust, autonomous European space defense industrial base.
  • May 2024: The Small Sat Europe Panel
    Meeting in Amsterdam, defense experts gathered to debate the execution of these strategic frameworks. The consensus was clear: while policy documents are vital, operational execution, rapid procurement, and industrial resilience must be accelerated to counter near-peer adversaries.

Supporting Data: The Proliferation of SmallSats and Electronic Warfare

The strategic calculus of space defense has been fundamentally altered by two physical and operational realities: the rise of proliferated Low Earth Orbit (pLEO) constellations and the persistence of electronic warfare.

The Power of Proliferated LEO Constellations

Historically, military space operations relied on a small number of highly capable, multi-billion-dollar satellites positioned in Geostationary Orbit (GEO). These systems were highly centralized, making them lucrative targets for adversaries.

Today, the paradigm is shifting toward "proliferated LEO" (pLEO)—networks of hundreds or thousands of smaller, cheaper satellites working in unison.

Attribute Legacy GEO Systems Proliferated LEO Constellations
Asset Count 1–5 large satellites 100–1,000+ SmallSats
Unit Cost $500M – $1B+ per satellite $1M – $5M per satellite
Target Resilience Low (Single point of failure) High (Adversary must target dozens to disrupt)
Launch/Refresh Cycle 10–15 years 3–5 years
Latency High (~240ms) Low (~30-50ms)

As defense analysts on the Space Minds panel noted, a proliferated architecture drastically increases the cost-to-kill ratio for adversaries. To disable a network like SpaceX’s Starlink or Europe’s upcoming IRIS² constellation, an adversary would have to expend hundreds of ASAT missiles or execute highly coordinated, large-scale cyberattacks, making kinetic interception economically and strategically unviable.

The Reality of Electronic Warfare in Europe

While kinetic ASAT attacks remain a worst-case scenario, electronic warfare (EW) is an ongoing, daily reality. GPS jamming and spoofing have become routine occurrences in Europe, particularly around the Baltic Sea, Poland, and the Black Sea regions.

Data collected by civil aviation authorities and open-source intelligence platforms reveals that thousands of commercial flights in European airspace have experienced GPS interference, largely attributed to Russian EW installations in Kaliningrad and the Kola Peninsula. This constant "gray zone" warfare highlights the urgent need for Europe to develop highly secure, jam-resistant military communications (MILSATCOM) and alternative positioning, navigation, and timing (PNT) systems.


Official Responses: From Sovereign Commands to Allied Synergy

European governments and international bodies are actively restructuring their organizations to address these vulnerabilities, though challenges remain regarding integration and sovereign pride.

France’s Active Defense Doctrine

France remains the vanguard of European military space policy. French officials have advocated for "active space defense," which includes the development of laser-armed nano-satellites (such as the Yoda-patroller program) designed to deter and disable snooping adversary satellites. French space doctrine does not seek offensive escalation but asserts the right to defend French orbital assets through proportional active measures.

How should Europe’s militaries respond to space threats

NATO’s Joint Space Operations Centre

In response to the fragmented nature of European militaries, NATO established its Joint Space Centre at Ramstein Air Base in Germany. The center serves as a clearinghouse for space domain awareness (SDA) data, coordinating information from national space commands to provide a unified picture of orbital threats. NATO’s approach emphasizes integration, ensuring that space-derived intelligence, surveillance, and reconnaissance (ISR) data is delivered seamlessly to commanders on the ground, in the air, or at sea.

The European Union’s Push for Autonomy

The European Union, through the European Space Agency (ESA) and the EU Agency for the Space Programme (EUSPA), is pushing heavily for strategic autonomy. The flagship initiative is IRIS² (Infrastructure for Resilience, Interconnection and Security by Satellite), a multi-orbital secure connectivity constellation. IRIS² is designed to provide European governments, militaries, and critical infrastructure operators with sovereign, secure, and jam-resistant communication channels, reducing reliance on commercial US providers like Starlink.


Implications: Deterrence, Supply Chains, and the Industrial Imperative

The discussions on the SpaceNews stage in Amsterdam pointed to several critical implications for the future of European security and the global space industry.

1. The Blurring Line Between Commercial and Military Assets

The war in Ukraine has demonstrated that commercial space systems are critical national security infrastructure. This reality poses legal and operational challenges: If an adversary hacks or physically attacks a commercial satellite used by a European military, does that constitute an act of war? European policy must establish clear red lines regarding the protection of commercial space providers operating on behalf of national defense.

2. Supply Chain Resilience and Standardized Hardware

To deploy resilient, proliferated constellations quickly, the defense industry must move away from bespoke, slow-moving procurement cycles. This shift requires a robust supply chain capable of delivering high-reliability, space-grade components at scale.

This industrial need highlights the vital role of global technology distributors. Companies like Arrow Electronics (sponsor of the Space Minds podcast) serve as critical links in the aerospace and defense ecosystem. By sourcing, integrating, and managing the lifecycles of electronic components and enterprise computing products, such distributors enable defense contractors to build and deploy next-generation satellite systems faster.

For Europe to achieve strategic autonomy, it must cultivate a domestic supply chain that leverages commercial-off-the-shelf (COTS) components ruggedized for the harsh environment of space, reducing lead times from years to months.

                                    +---------------------------+

3. The Sovereign vs. Allied Dilemma

Perhaps the greatest hurdle for Europe is coordination. Unlike the United States, which has a unified Space Force, Europe’s space capabilities are fragmented across national commands (France, Germany, Italy, the UK) and intergovernmental bodies (the EU and ESA).

While national governments are reluctant to cede control over their defense assets, the physics of space warfare demand unified action. An attack on a French satellite could easily create debris that destroys a German or Italian asset. Achieving true interoperability—where sensor data, command structures, and satellite networks are shared seamlessly across European allies—remains the ultimate goal, and the ultimate challenge, for the continent’s military planners.
