EU Defense Officials Resist Legislation to Restrict Use of U.S. Cloud Services

Senior EU defense officials are openly resisting the Cloud and AI Development Act's mandate to use domestic technology, warning that Europe trails the US by eight to ten years in cloud and AI defense platforms — and that a forced switch would undermine NATO interoperability.
What does the bill actually require?
The European Commission proposed the Cloud and AI Development Act in June, requiring member states to classify public services by sensitivity — the highest tier mandates European-only technology.
The Commission's own estimate: only about 1% of public services would hit that top threshold.
This means → the scope looks narrow on paper, but defense systems sit squarely inside that 1% — the real impact is far larger than the number suggests.
Why do defense officials say it cannot be done?
Two senior EU defense officials told the Financial Times that the US leads Europe by roughly eight to ten years in cloud and AI defense platforms.
One official was blunt: "We are still buying a lot of American equipment because not doing so would be less safe."
In plain terms = Europe's defense digital backbone already runs on US technology. One defense executive called it a "spinal cord" — "transplanting it without killing the patient is impossible."
Why is the F-35 the core obstacle?
US cloud services are deeply embedded in frontline hardware, including the F-35 fighter jet's operating systems.
Camille Grand, secretary-general of AeroSpace and Defence Industries Association of Europe, said: "No country will throw away an F-35 because it runs on an American digital cloud that is hard to replace quickly."
This means → the weapons platform is locked to the cloud platform. Switching clouds means replacing the entire combat system — the switching cost is not "high," it is "unbearable."
Grand added that restricting US cloud providers could also hinder the growing need for large-scale battlefield data sharing among allied forces.
What does Finland's "kill switch" worry reveal?
Finnish Foreign Minister Elina Valtonen said Helsinki is preparing for the risk that a foreign supplier could use a "kill switch" to cut off critical computing capacity.
But her goal is not wholesale replacement: "Not owning every piece of the AI stack, but making sure no critical piece can be switched off at will."
This reflects a pattern: even the most dependency-aware countries pursue a pragmatic line — not "build everything ourselves," but "no single point of foreign shutdown."
Why does the Commission believe it can push this through?
The Commission argues the bill hands classification decisions to member states, not a one-size-fits-all mandate — and the timeline from negotiation to enforcement leaves room for industry to catch up.
Supporters contend that without government procurement demand, European cloud providers can never reach scale.
Airbus announced in July it would migrate some of its most critical applications from AWS to French cloud provider Scaleway — one of the few concrete cases of a major European company pursuing cloud sovereignty.
Where is the real fault line in this fight?
One European diplomat called the strictest tier "unrealistic" — "no company today, American or European, can meet that standard."
People familiar with the matter say several US tech firms have already engaged European defense ministers and NATO officials over the proposed legislation.
In plain terms = the real question is not whether Europe wants digital sovereignty — it is whether a path exists that neither rips Europe's defense systems off American technology nor leaves the continent without a backup.
