US software company Palantir Technologies has sought to ease European concerns about dependence on American defence technology, insisting that neither the company nor the US government can remotely disable the military artificial intelligence platform it supplies to NATO. The reassurance comes as recent disruptions to Ukraine’s satellite communications have intensified questions about whether European countries can rely on foreign technology during a security crisis.
Louis Mosley, Palantir’s executive vice president for the United Kingdom and Europe, told Reuters on October 21 that customers retain operational control over the Maven Smart System, an AI-powered platform He said the software contains no mechanism that would allow Palantir or US authorities to shut it down remotely.
Mosley described the recent developments involving satellite services in Ukraine as deeply concerning but stressed that Palantir’s arrangements with customers were different. According to him, organisations that purchase the company’s software maintain control over how it operates, without an external party being able to deactivate it.
The issue has attracted greater attention following reports that Ukraine experienced restrictions affecting its use of military-grade satellite communications. Starshield, a service connected to SpaceX’s Starlink satellite constellation, reportedly imposed restrictions that prevented terminals from functioning on fast-moving platforms. The disruption affected activities including the use of interceptor drones designed to counter Russian attacks.
US and Ukrainian officials, along with SpaceX chief executive Elon Musk, have provided differing explanations for the incident. However, Ukrainian and European officials reportedly suspected that political considerations may have played a role. The disruption occurred after US President Donald Trump called on Ukraine to stop attacking Russian oil refineries, adding to concerns about the potential influence of Washington’s political decisions on access to critical military technology.
These developments have intensified debate among European policymakers over the risks of relying on US companies for essential defence capabilities. Officials are increasingly concerned that technology supplied by private American firms could become unavailable or restricted during periods of political disagreement, potentially affecting Europe’s ability to defend itself.
Palantir’s assurances are intended to distinguish its military software from satellite services whose availability depends on decisions by their operators. Mosley said the Maven platform could continue functioning independently of Palantir, allowing customers to manage the system themselves.
The Maven Smart System collects and analyses large volumes of battlefield information from satellites, radar installations and other sensors. By combining these sources, the platform helps military personnel build a clearer picture of conditions on the battlefield and make decisions more quickly.
In June 2026, the alliance announced that the platform had reached what it described as full technical operational capability, marking a significant milestone in its deployment.
Despite NATO’s adoption, several European member states have not introduced Maven across their national armed forces. France and Germany, in particular, have expressed reservations about becoming dependent on American technology at a time when political relations between Trump and European leaders have frequently been strained.
Germany has raised specific concerns about the potential access of private-sector employees to sensitive military information. In April 2026, the head of the country’s cyber command ruled out purchasing Maven, arguing that allowing staff from a private company to access Germany’s national military database was unacceptable.
Mosley responded that the involvement of Palantir personnel in operating the system was determined by each customer. Where employees were required, he said, they would be citizens of the relevant country and would hold the necessary security clearances.
He also maintained that customers could run the platform without assistance from Palantir staff. According to Mosley, the company already has numerous military and commercial clients worldwide that operate its software independently.
The distinction between owning software and controlling its day-to-day operation remains central to the wider debate. Even if a system can be managed independently after installation, governments must still consider questions surrounding maintenance, technical support, software updates and the long-term ability to operate without the original supplier. These issues are particularly important when the technology supports military planning and operational decisions.
The recent satellite disruption has therefore highlighted a broader strategic challenge for European governments: determining how much control they retain over defence systems developed or supplied by foreign companies. While Palantir says its Maven platform cannot be remotely disabled by the company or the US government, European officials must weigh such assurances against their wider security requirements.
For NATO, the system offers a way to process complex battlefield information and improve the speed of military decision-making. For countries such as France and Germany, however, concerns about data access, national sovereignty and dependence on external suppliers remain important barriers to adoption.
The debate is likely to remain significant as European governments assess their defence capabilities and the risks associated with relying on technology providers based outside the continent. Palantir’s position is that its customers retain control over Maven, but the broader question of technological independence continues to shape discussions about Europe’s future military preparedness.
