Palantir has told European officials that neither it nor the US government can switch off the Maven Smart System, the AI platform its software provides to NATO’s military headquarters and several European armed forces. Louis Mosley, Palantir’s executive vice president for the UK and Europe, gave the assurance in a Reuters interview in Brussels on Wednesday, as a dispute over Ukraine’s restricted satellite services sharpened European concern about depending on American defence technology.
The comments land days after Ukraine reported that its use of the military-grade Starshield service, which runs on SpaceX’s Starlink constellation, had been restricted so that terminals stopped working on fast-moving platforms, hampering tasks such as flying interceptor drones against Russian attacks.
What Sparked The Kill Switch Question
US and Ukrainian officials and SpaceX chief executive Elon Musk have offered conflicting explanations for the Starshield disruption. Ukrainian and European officials, Reuters reports, suspected a political motive because the restriction came after US President Donald Trump demanded that Ukraine stop hitting Russian oil refineries.
That suspicion has widened into a broader policy question in European capitals: if a US supplier or the US government can restrict one battlefield system, what stops it doing the same to the AI platforms now woven into allied command structures? Maven is exactly such a platform, which is why Palantir moved to answer the question publicly rather than let it circulate.
What Mosley Said About Maven’s Controls
“What we have seen in the news over the past few days around Starlink is extremely concerning,” Mosley told Reuters. “But as concerns Palantir, I can provide categorical reassurance that where customers have bought our software, they are in full operational control of that software.”
“There are no kill switches,” he said. “There’s no ability for Palantir or the US government to reach in and switch it off.” The claim is architectural as much as contractual: Palantir is saying the software, once bought and deployed by a customer, runs under that customer’s operational control, with no remote disablement path held by the vendor or by Washington.
What The Maven Smart System Does
Maven Smart System processes vast amounts of data from satellites, radars and other sensors to give military officers a single picture of the battlefield and speed up decision-making. It is used by NATO’s military headquarters and by several European armed forces, making it one of the most deeply embedded American AI systems in European defence.
The reassurance also arrives while the politics of military AI are unsettled inside the industry itself. Researchers at Google DeepMind have been resigning over Google’s military AI contracts, arguing that vendors have limited visibility into how the Pentagon deploys their models — the mirror image of the European concern that vendors might retain too much control.
Why It Matters
Maven Smart System sits at the point where Europe’s two defence anxieties meet: allied forces now depend on American AI for the sensor fusion their commanders use, yet the Starshield episode showed how quickly access to a US-run service can become a political variable. Palantir’s answer is that Maven is sold software under customer control, not a service Washington can throttle — a distinction that matters for every European procurement officer weighing US platforms against sovereign alternatives, and for defence-AI suppliers such as Helsing and Destinus, whose European ownership is part of their pitch. The claim will be tested less by statements than by contract terms: whether European buyers negotiate the audit and escrow rights that would let them verify there is no switch to flip. It also contrasts with the offensive side of military AI, where state-linked groups are already running AI agent frameworks against allied supply chains.
Background
Project Maven began in 2017 as a Pentagon effort to use machine learning on drone footage, and Palantir took over the programme’s main contract in 2019 after Google withdrew amid employee protests; the Maven Smart System has since grown into NATO’s and the US military’s central platform for fusing sensor data, and Palantir has expanded it across European armed forces as defence AI spending surged after Russia’s invasion of Ukraine.
