Palantir moved to calm European nerves on Wednesday, saying the Maven Smart System AI platform used by NATO has no “kill switch” and cannot be shut off remotely by either the company or the United States government. The assurance comes as European policymakers grow increasingly anxious about their dependence on American defense technology.
The message was delivered by Louis Mosley, Palantir’s executive vice president for the UK and Europe, in an interview with Reuters in Brussels, and it is notable for how categorical it was.
What Palantir Said
Mosley told Reuters on Wednesday that neither Palantir nor the US government can switch off the Maven Smart System AI platform used by NATO’s military headquarters and several European armed forces.
“What we have seen in the news over the past few days around Starlink is extremely concerning,” Mosley said. “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.”
He continued: “There are no kill switches. There’s no ability for Palantir or the US government to reach in and switch it off.”
Why This Matters Now
The timing of the reassurance is no accident. Last week, Ukraine reported disruptions to its military-grade Starshield satellite service, which runs on SpaceX‘s Starlink constellation. Terminals reportedly stopped working on fast-moving platforms, hampering tasks such as operating interceptor drones against Russian attacks.
US and Ukrainian officials, along with SpaceX CEO Elon Musk, have offered conflicting explanations for the disruption. But Ukrainian and European officials said they suspected a political motive, because the outage came after US President Donald Trump demanded that Ukraine stop striking Russian oil refineries.
Those suspicions have revived a long-running European worry: that reliance on American technology vendors gives Washington an implicit veto over Europe’s ability to defend itself.
What Maven Does for NATO
The Maven Smart System processes vast amounts of data from satellites, radars and other sensors to give military officers a picture of the battlefield and speed up decision-making. NATO bought the system for its Supreme Headquarters Allied Powers Europe (SHAPE) in 2025, and the alliance declared it had achieved “full technical operational capability” in June 2026.
European Skepticism Runs Deep
Despite NATO headquarters’ adoption, several European members have not followed suit. Germany and France have not adopted Maven for their own armed forces, citing concerns about relying on a US company amid frequent tensions between Trump and European leaders.
In April this year, the head of Germany’s cyber command ruled out buying Maven, calling it “inconceivable” for employees of a private company to have access to the country’s national military database.
Mosley responded that customer involvement of Palantir staff was “entirely at the discretion of the customer.” Such employees would be citizens of the country concerned and hold the required security clearance, he said, adding: “It can absolutely be operated independently of us, and we have many, many customers around the world, both actually in the military and in the corporate world, who do that.”
Why It Matters
Palantir’s public pledge puts the company on the record about one of the most sensitive questions in defense technology: who really controls AI systems that military alliances depend on. Whether the reassurance satisfies European skeptics remains an open question, but it signals how the Palantir-NATO relationship has become a focal point in the broader debate over technological sovereignty. As AI systems take on more critical military roles, questions of kill switches, remote access and vendor dependence are likely to intensify, not fade.
