Facing waning trust in US support, Europe is investing billions in satellite systems—but internal divisions reveal limits to strategic autonomy.
Key Role of Satellite Data for National Security
Access to satellite reconnaissance is now essential for any nation prioritizing its security, a reality underscored by the Ukraine conflict where US satellite data proved critical.
Russia’s provision of satellite data to Iran and previously to the Houthis demonstrates how such information amplifies capabilities and enables aggressive actions, including attacks on commercial shipping.
US Strategy and Limited Support for Allies
The US National Security Strategy signals a shift towards “limited but critical” support for allies, with intelligence sharing—reliant on its vast satellite fleet of approximately 1,500 satellites—being a key component.
Europe’s Push for Strategic Autonomy with IRIS²
Following decades of reliance on US military and intelligence assets, Europe is accelerating efforts to close the gap, exemplified by the December 2024 agreement to build the IRIS² system—a constellation of 290 satellites for secure communication and reconnaissance—at a cost of nearly 11 billion euros.
The European Commission frames the program as a foundation for strategic autonomy in the digital age.
Potential for Significant Change in European Defense
The IRIS² constellation, covering from the Arctic to North Africa, could provide substantial communication and reconnaissance capabilities for European governments and militaries, potentially strengthening allied commitments.
However, the initiative also reflects a lack of confidence in the US’s willingness to consistently share satellite intelligence.
Germany Pursues Independent Satellite System
Despite the EU-wide IRIS² project, Germany plans to invest 10 billion euros in a separate constellation of 100 military satellites, partially duplicating IRIS²’s capabilities.
While IRIS² will serve both civilian and commercial purposes, Germany’s system will be strictly military, with Berlin prioritizing sovereign control over data utilization and reconnaissance direction.
Political Motivations Behind Germany’s Decision
Germany’s decision to pursue its own system may stem from concerns that the European system won’t meet its technical requirements, but ultimately reflects a political desire for independent control over critical defense assets.
Even opposition parties, like the AfD, support the investment, viewing it as responsible national security policy.
Erosion of Trust and the Value of Sovereignty
In an increasingly fragmented world, trust is a valuable commodity, as evidenced by the US-Israel relationship and the growing divergence between Europe and the US.
The drive for European satellite capabilities, spurred by eroding transatlantic trust, underscores the renewed importance of sovereignty in matters of existential significance.
