Ukraine’s military has suddenly had its access to Starlink satellite internet terminals restricted as the Trump administration has increased pressure on Ukraine to halt long-range strikes on Russia’s oil industry immediately.
The terminals, which are produced by Elon Musk’s SpaceX but managed by the US government, are a key component of Ukraine’s military operations and the sudden restrictions on the terminals travelling at high speeds on Tuesday evening led to the failure of several combat missions, said an adviser on military technology to Ukraine’s president, Volodymyr Zelenskyy.
The sudden outage came as Russia launched ballistic missiles at Ukraine without any advance warning from the US for a second night. For years, the US has provided Ukraine with intelligence when strikes were about to take place.
Donald Trump has denied that his administration has cut intelligence sharing with Ukraine. Zelenskyy also indicated that the US was continuing to share intelligence with Ukraine in an interview with NPR aired on Wednesday, but confirmed that military advisers had received threats from the US that intelligence sharing could be limited.
Ukraine did not receive any warning before Russia launched its first barrage of ballistic missiles on Tuesday evening, according to Col Yurii Ihnat, a spokesperson for the air force. But it did receive warnings from “foreign partners” about three subsequent barrages, leaving further confusion about whether or not the US is intentionally withholding intelligence from Ukraine.
Musk said that Starlink is not licensed to clients who are using weapons, and that the Ukrainian military was linked to a separate network called Starshield, which is operated by the US government. “This is not under SpaceX control,” Musk wrote.
Terminals travelling at more than 100mph and using a version of Starlink for the military and other national security agencies suddenly lost connectivity, said Serhiy Beskrestnov, in what appeared to be a targeted outage meant to disrupt military operations.
“Our armed forces did not receive a warning about these restrictions and this led to the failure of a number of missions,” said Beskrestnov, who is also a popular military blogger. “It’s clear that this action cannot be a coincidence and is connected to the current political situation.”
Limiting Starlink’s access speeds would have a significant effect on Ukraine’s air defences because it is being used, according to Beskrestnov, in “the most current effective solution”: interceptors that target the jet-powered Shahed drones now deployed in large numbers to bomb Ukraine.
“With their actions our partners are depriving us of one of the few chances we have to defend ourselves,” he added in a follow-up post. Shahed interception rates had already dropped from more than 90% to about 60% when Russia upgraded its engines to jet power in the early summer.
But there have been no reports that access for static Starlink terminals has been cut, meaning critical battlefield communications for soldiers should remain unaffected. The detection of incoming Russian missiles and drones relies on other technologies.
Musk has supported Trump’s calls for Zelenskyy to be replaced as Ukraine’s leader – an extraordinary act of political interference against a wartime ally – as a personal feud between the two presidents has burst into the open.
The reports that Starlink was being throttled on the frontlines were interpreted by some as further pressure on Ukraine to end the fighting and make a deal with Russia at any cost.
Serhii Sternenko, a political activist with close ties to the military, first reported the outage and later said that the speeds at which the loss of connectivity occurred had fallen even lower. “It is likely that the company ‘SpaceX’ resorted to such measures at the request of the Trump administration,” he said. “Ordinary satellite communication terminals are currently operational.”
Trump has demanded that Ukraine stop striking Russian oil refineries, which he has blamed for the high cost of diesel, although most analysts say that the closure of the strait of Hormuz has had a far larger impact on global energy prices.
Zelenskyy had suggested, though not said, that the US was intentionally withholding intelligence from Ukraine about impending Russian missile strikes.
Russia carried out a massive strike against Ukrainian energy infrastructure late on Tuesday evening, Zelenskyy said, launching 39 ballistic missiles and 120 attack drones against Kyiv and Kharkiv. The strikes hit five big power plants, key substations and other infrastructure that sustains major cities including Kyiv.
“The strike was entirely deliberate and demonstrative in its scale – Russia has never before shown such ostentatious disrespect toward the United States,” Zelenskyy said. “Russia does not consider the American president’s statements strong.”
At least 600,000 people were now without power, he said, adding that outages could become even more widespread.
Trump last week announced an “energy ceasefire” between Russia and Ukraine that has not been confirmed by either side. Zelenskyy said he had not heard of the deal until Trump announced it on his Truth Social site, and the Kremlin on Wednesday claimed it was abiding by the ceasefire because Trump had not specified which energy infrastructure it included.
Dmitry Peskov, the Kremlin’s spokesperson, told reporters: “The energy truce proposed by Trump was not specified in detail, so it cannot be claimed that Russia is failing to observe it.”
Ukraine is observing a short-term moratorium on striking Russian refineries while Kyiv seeks to show that it is ready for talks with Russia. Zelenskyy arrived in London on Wednesday to meet Andy Burnham, Britain’s prime minister. He will also be received by King Charles.
Zelenskyy is seeking new negotiations with the US. He has sent proposals to the Trump envoys Steve Witkoff and Jared Kushner, the president’s son-in-law, saying Ukraine was ready to work towards a ceasefire and “Russia must also be part of this agreement”.
