Palantir has told European allies that nothing it sells them comes with an off switch. Louis Mosley, the company’s executive vice president for the UK and Europe, said in a Reuters interview in Brussels that neither Palantir nor the US government can disable the Maven Smart System, the AI platform used by NATO’s military headquarters and several European armed forces. “There are no kill switches,” Mosley said. “There’s no ability for Palantir or the US government to reach in and switch it off.” The reassurance landed at an awkward moment, days after disruptions to Ukraine’s Starlink and Starshield services made European capitals ask a question they had mostly left theoretical: who can turn off the American technology that their militaries now run on?
What Palantir actually said
The Maven Smart System fuses data from satellites, radars, drones and other sensors into a single battlefield picture, cutting the time officers need to make decisions. NATO bought Maven for its Supreme Headquarters Allied Powers Europe (SHAPE) in 2025 and declared it at “full technical operational capability” in June. Mosley said customers who have bought the software hold “full operational control” of it, and that whether Palantir employees help operate the system is “entirely at the discretion of the customer”. Where such staff are used, he said, they are citizens of the country concerned and hold the required security clearance. He added that many military and corporate customers already run Palantir software independently of the company.

The Starlink scare behind the reassurance
Why now? Because in mid-October Ukraine’s access to SpaceX’s Starshield service was throttled to around 160 km/h, breaking the link between drones and their operators whenever the aircraft flew faster than that — routine speed for the strike and interceptor drones Kyiv depends on. Ukraine said service was restored on 15 October, then said it was still limited; President Volodymyr Zelensky said this week that normal speed had not fully returned, and President Donald Trump said Elon Musk had “put it back”. Musk said Starshield is controlled by the US government. Reuters reported the order came from inside the White House. Ukrainian and European officials suspect a political motive, because the throttling followed US pressure on Kyiv to stop striking Russian oil refineries. Mosley called the Starlink news “extremely concerning”.
Why Berlin and Paris still hesitate
Germany and France have so far declined to adopt Maven for their own armed forces, citing concern about reliance on a US supplier. That hesitation is not really about the software’s quality. A battlefield AI system is not a box you buy once: it is licensed, updated, patched and increasingly tied to cloud services and models hosted somewhere else. Buying it means accepting a long-term relationship with a company and a government that can both change policy overnight. Palantir’s assurance addresses the most dramatic scenario, the remote kill switch. It does not address the quieter dependencies.

Analysis: control is a contract, not a configuration
The kill-switch debate is partly about code and mostly about leverage. No evidence has emerged that any switch was flipped on NATO systems, and Palantir’s claim is a promise about future behaviour rather than something a customer can verify from the outside. That is why the practical European response is likely to be contractual and architectural rather than rhetorical: source-code escrow, on-premises hosting, locally cleared operators, documented exit paths, and a requirement that critical functions keep working if a vendor relationship ends. Redundancy is the other half. A military that can only plan with one AI system has a single point of failure whether or not that system has a kill switch. Europe’s sovereignty funds and procurement rules point in the right direction, but they take years to bite — and Ukraine’s experience suggests the next test may arrive in days.
What to watch
- Whether Germany or France moves toward Maven, or backs a European alternative instead.
- Whether NATO writes escrow, local-hosting and exit clauses into future AI contracts.
- Whether Ukraine’s Starshield speeds stay restored — and whether anyone admits who ordered the throttling.
- Whether Palantir offers independent verification of its “no kill switch” claim, or relies on trust.
