Palantir rules out 'kill switch' on NATO AI system amid US tech reliability fears

European allies seek reassurances after Starshield disruptions in Ukraine

US software firm Palantir has moved to allay European fears over dependence on American technology, declaring that neither the company nor the US government can switch off the Maven Smart System AI platform used by NATO. The reassurance comes after recent disruptions to Ukraine's Starshield satellite service raised alarm over political leverage on allied military systems.

Louis Mosley, Palantir's executive vice president for the UK and Europe, told Reuters that customers who have bought the company's software are in full operational control. 'There is no ability for Palantir or the US government to reach in and switch it off,' he said, referring to reports that the White House ordered SpaceX to limit Ukraine's access to Starshield, the military-grade version of Starlink. Both the civilian and military networks are operated by Elon Musk's SpaceX.

Maven, an AI system that fuses data from satellites, radar, drones and other sensors to accelerate battlefield decisions, was supplied to NATO under a €480 million contract awarded in 2025. It is now fully operational at NATO's Allied Command Operations at SHAPE. However, some European members have opted out: France developed its own service, Arcadia, to maintain technological sovereignty, while Germany's Vice Admiral Thomas Daum said allowing industry personnel access to national datasets is 'out of the question'.

Mosley characterised the Starshield incident as 'extremely concerning' but stressed Palantir's platform has no kill switch. The conflicting accounts from President Donald Trump and Elon Musk over who ordered the restrictions underscored European unease. The episode has sharpened debate about transatlantic tech reliance and whether allies can trust US-controlled systems in a crisis.

Analysis

Why This Matters

European NATO members rely on US technology for military communications and data processing; the Starshield episode shows how that dependency can be exploited as political leverage.
Palantir's categorical denial of a kill switch aims to restore trust but may not reassure countries that have already developed alternatives.
The incident is likely to accelerate European calls for strategic autonomy in defence technology.

Background

Palantir won a €480 million contract in 2025 to supply its Maven AI system to NATO. The platform, now fully operational at SHAPE, processes battlefield data from multiple sensors to speed up decision-making. In October 2026, Ukraine accused Washington of deliberately slowing Starshield, its military satellite service, sparking a dispute between President Trump and Elon Musk over who ordered the limits and raising broader questions about US control over allied infrastructure.

Key Perspectives

Palantir: Argues customers retain full operational control; neither the company nor the US government can disable the Maven system. Palantir says its contractual arrangements prevent any remote kill switch. European skeptics (France, Germany): France has built its own Arcadia system; Germany refuses to allow private-company access to national defence datasets. Both see dependence on a US firm as a sovereignty risk. US Government / SpaceX: Conflicting accounts from Trump and Musk over responsibility for Starshield restrictions have fuelled distrust, leaving allies uncertain about future access.

What to Watch

Whether additional NATO members follow France and Germany in pursuing independent AI systems.
Potential EU policy moves to mandate sovereign control over critical defence technology.
Any evidence that US authorities can influence Maven operations despite Palantir's denials.
