Starlink’s 160-Kilometer-Per-Hour Limit Disrupts Ukrainian Drone Missions
Key Facts
Ukraine said on October 14 that SpaceX had imposed a limit on some Starlink services in the country, disrupting combat drone missions, according to a Reuters report. The limit cuts data connectivity when a terminal is moving at more than about 160 kilometers per hour, according to the Associated Press, which said the measure was imposed without warning. An adviser to the Ukrainian president said the military version of the service stopped working above that speed. This puts a commercial satellite connection at the heart of military operations that rely on drones. A Ukrainian adviser said the forces had received no advance warning and that the restrictions disrupted several missions.
The effects of the limit appeared, according to Ukraine’s Seventh Corps, even at speeds below the stated threshold. The corps said connectivity could drop for between 10 and 20 seconds at a speed of between 110 and 120 kilometers per hour. It added that the interruption makes it harder to control drones in flight. Reuters reported that the corps said some missions had been canceled. The Associated Press also cited Ukrainian commanders’ reports of lost drones and disrupted missions. Officials described Starshield as Starlink’s military version and a communications backbone for Ukrainian drone operations, while their reports point to some drones being lost, not all of them crashing.
Ukrainian President Volodymyr Zelenskyy said the speed restrictions undermine frontline supply, medium-range strikes and Ukraine’s ability to counter Shahed drones. The statement highlights the scope of the impact Kyiv attributes to the connectivity limit, from drone control to supply and air-defense missions. The Associated Press reported that U.S. Defense Secretary Pete Hegseth denied that the service had been withdrawn and referred the question of the decision to the terms of use and the company’s options. Hegseth said, "Starlink has the option to make those decisions." The comments place the decision within the company’s authority, but do not establish whether the limit was imposed independently by SpaceX or in coordination with the U.S. administration.
Published accounts have differed over who was responsible for the decision. A Wall Street Journal report attributed the restrictions to an order from Elon Musk, but also noted conflicting accounts over whether U.S. President Donald Trump had advance knowledge and whether Musk acted alone or at the administration’s request. The report said the question was whether "the world’s richest man acted alone or at the administration’s request." Officials’ comments cited in the reports did not resolve the dispute. The Associated Press said Ukraine had not received a clear official explanation of who was responsible for the restrictions or why they were imposed.
On October 22, a European official familiar with the matter told the Associated Press that the speed limit remained at about 160 kilometers per hour. The agency noted that Ukraine had not received a clear official explanation of who was responsible for the measure or what motivated it as of that date. This came after EL7 published a report on October 15 about technical restrictions on military Starlink terminals in Ukraine. On the same day, EL7 data showed SPCX shares closed at $144.75. The available data do not include the stock’s high or low during the session.
Ukraine said it was in talks with SpaceX and the Pentagon to lift the limit, while acknowledging that it did not know why it had been imposed, according to the Associated Press. In a separate statement, an adviser to the Ukrainian president said the restrictions had not been lifted, despite Trump’s announcement that the service had returned to full speed. The agency quoted the adviser as saying the restrictions were still in place on Friday. A Ukrainian official also told the Kyiv Independent that claims the service had been fully restored were incorrect, and that the limit continued to constrain medium-range strikes and the interception of fast drones. Zelenskyy’s office said the Ukrainian president and U.S. Secretary of State Marco Rubio had agreed to speak again soon to follow up on the status of Starlink and Starshield. In Washington, Democratic Senator Richard Blumenthal announced an investigation into how communications systems used in Ukrainian defense systems were slowed.
