European governments spent this week watching a US satellite service slow down over a battlefield and asking who is actually in charge. Into that stepped Palantir, whose military AI platform runs inside NATO's headquarters in Brussels. There is no kill switch, its UK and Europe chief Louis Mosley told Reuters in Brussels on 22 October: "There are no kill switches. There's no ability for Palantir or the US government to reach in and switch it off."
The same day, in a separate interview with Bloomberg, the same executive said Europe "is going to have to accept some dependency" on the United States, at least for now. Both statements can be true at once. The gap between them is where Europe's digital sovereignty argument actually sits.
What Palantir promised, and what it did not
Maven Smart System is the AI platform NATO's military headquarters uses to fuse satellite, radar, drone and other sensor data into a battlefield picture. NATO bought it for its Supreme Headquarters Allied Powers Europe in 2025 and declared full technical operational capability in June this year.
- The assurance: customers keep full operational control of software they have bought, Mosley said. Whether Palantir employees help run it is at the customer's discretion, and any such employees would be cleared nationals of that country. "It can absolutely be operated independently of us," he added.
- The limit: what was offered is a verbal guarantee in an interview. There is no published audit, no independent verification, and no technical document showing how deployment is separated from the vendor. For a NATO deployment, that is a weaker promise than it sounds.
Why the question came up at all
On 14 October Ukraine reported that its military-grade Starshield service, which runs on SpaceX's Starlink constellation, had been restricted so that terminals stopped working on fast-moving platforms — exactly the condition interceptor drones fly at. The speed cap, around 160 km/h, was imposed without explanation, and the explanations that followed contradicted each other: Musk said the US military and the president decide usage limits, while Secretary of State Marco Rubio said the administration cannot direct SpaceX because it is a private company.
The confusion dragged on. On 23 October Politico reported that limits of 140–160 km/h were still in place despite Donald Trump's claim that Elon Musk had lifted them, with a drone pilot describing connections that drop above 180 km/h. Only on 24 October did Ukraine's defence ministry say speeds had recovered past 400 km/h, a confirmation Volodymyr Zelensky repeated — while a source in Donetsk told CNN that day that speeds there were still capped at 160 km/h.
The refusals were never about switches
Two European NATO members have declined to field Maven for their own forces. In April, the head of Germany's cyber command, Vice Admiral Thomas Daum, said it was "inconceivable" to grant industry staff access to the national military database. In June, France announced its domestic intelligence agency would end its Palantir contract in favour of a local provider.
Notice what those objections are about: people, access and update flows — not a hidden off button. A kill switch is the dramatic version of dependence. The boring version is a vendor whose staff touch your data, whose releases your systems depend on, and whose government can lean on it. Palantir's reassurance addresses the first thing; Europe's policy is about the second.
What Europe is choosing between
Mosley's pitch in the Bloomberg interview was that competition should be judged on performance, not politics, and that Maven is "a massive enabler of lots of European defence". He also pointed out that Europe's hardware chokepoints run through China: "You can't manufacture drones without magnets."
The trade-off is real on both sides. Refusing US tools costs capability, integration work and money; keeping them keeps a dependence that a single phone call just rattled across a war zone. The EU's technology-sovereignty package, including the proposed Cloud and AI Development Act, is the legislative answer, but it is still being negotiated rather than built.
One honest note: Starshield speeds came back, and NATO's Maven has never been switched off. What Europe learned this month is not that someone did pull a plug. It is that nobody can prove who could.
