A Ukrainian defense technology adviser says geographic and speed limitations on Starlink's civilian system made Elon Musk's terms-of-service allegation physically impossible, as Ukraine and its allies accelerate efforts to build sovereign satellite alternatives.
A Ukrainian defense technology adviser publicly contested Elon Musk's assertion that Ukraine's military broke Starlink's terms of service by using the satellite network to conduct offensive drone strikes, deepening a dispute that has drawn in governments on both sides of the Atlantic.
Serhii Beskrestnov, a defense technology adviser to Ukrainian President Volodymyr Zelenskyy, wrote on Telegram on Sunday that pre-existing operational limitations on Starlink's civilian system made it "physically impossible" for Ukraine to have carried out the strikes Musk described.
"It is very strange that Elon Musk is unaware of the operational limitations of Starlink in Ukraine," Beskrestnov wrote, noting that Starlink's civilian network "does not function over the territory of Russia" and that Ukrainian drones operating with Starlink have been subject to a speed restriction of 70 to 90 km/h — roughly 43 to 56 miles per hour — for months.
"Consequently, it is PHYSICALLY IMPOSSIBLE for us to use commercial Starlink for deep-strike or medium-range strike operations," Beskrestnov wrote.
Musk had said on Saturday in a post on X that "Ukraine military violated Starlink terms of service and used it for offensive drone strikes to kill people," adding that SpaceX had closed the alleged loophole the previous week. Musk and SpaceX did not respond to requests for comment.
Ukrainian officials had previously said the service restrictions disrupted the country's military drone operations and left Ukraine exposed to Russian air attacks. Officials acknowledged on Saturday that high-speed service for both Starlink and Starshield — SpaceX's military-focused satellite network built on Starlink technology — had since been restored.
The episode has been marked by conflicting accounts over who authorized the restrictions. Musk at one point wrote on social media that the U.S. government was responsible for the decision, though President Donald Trump said he had no knowledge of it. Ukrainian officials said neither Starlink nor U.S. authorities gave advance warning before implementing the changes.
Musk has not addressed the reported absence of prior notification to Ukraine.
The dispute has accelerated efforts by Ukraine and its allies to build alternative satellite communication systems that would not depend on a single commercial provider. Poland's Deputy Minister of National Defense, Cezary Tomczyk, discussed his country's plans on a podcast called Influence Zone earlier this month.
Ukraine has also formalized partnerships with Nokia and satellite maker ICEYE: the two companies signed a letter of intent with Ukraine's Defense Ministry on Oct. 22 to explore sovereign communications infrastructure. Norway is also involved in those efforts.
At a broader European level, the EU is developing IRIS², a constellation of hundreds of satellites, though the bloc does not expect its first launches until 2029.
The financial stakes surrounding Starlink underscore the scale of what is in dispute. SpaceX's Starlink generated $5.25 billion in revenue in the third quarter of 2026, up from $3.1 billion in the same period a year earlier. Consumer subscribers accounted for $3.12 billion of that total, with government and enterprise customers contributing $2.13 billion. Customers funding Starlink access for Ukraine include the governments of Poland and France, the Pentagon, and a range of non-government entities.
With high-speed service now restored, the more immediate question is whether Ukraine can accelerate its sovereign alternatives quickly enough to reduce its operational dependence on SpaceX — a single provider whose decisions have twice left Kyiv scrambling to maintain communications during active combat.
