BRUSSELS — The European Union is under pressure to keep Ukrainian troops fully online after Elon Musk’s Starlink was restricted amid volatile U.S. support for Kyiv.

“It was a very dangerous and unpleasant surprise,” Ukrainian President Volodymyr Zelenskyy told reporters after EU leaders met in Brussels, referring to Starlink speed limitations experienced by military troops in recent days. “We were using Starlink to intercept jet-powered Shaheds [combat drones] that are attacking our civilian infrastructure and killing our families … When the speed limits were lowered, we became incapable of shooting [them] down.”

Ukraine has long relied critically on Musk’s satellite constellation for wartime efforts. Reuters reported Friday that the order to slow Ukraine’s military-grade Starshield service came from the White House, days after Washington pressed Kyiv to halt strikes on Russian refineries, amid soaring energy prices and ahead of November’s midterm elections.

“It is unacceptable for Ukraine’s defense — and therefore Europe’s security — to depend on the goodwill of a single American billionaire or on Donald Trump’s decisions,” French centrist Member of the European Parliament Christophe Grudler told POLITICO.

Ahead of Thursday’s high-level meeting, European lawmakers had been calling on the EU executive to fast-track Kyiv’s access to satellite capabilities already pooled under the bloc’s Govsatcom program — which gives participating governments secure communications capabilities.

Negotiations between the EU executive and Ukraine over this access have been ongoing since March, with no breakthrough. Norway and Iceland secured such an agreement earlier this year.

“What I don’t understand is why the European Commission and the Member States have not done everything possible to quickly reach an agreement that would allow Ukraine to benefit from it,” added Christophe Grudler, who wrote to EU leaders.

He also called on them to speed up work on IRIS² — the EU’s in-house, planned satellite network and full-fledged match to Starlink, which is only expected to come online in 2030.

Commission spokesperson Thomas Regnier confirmed in a statement that it is “currently in talks with Ukraine to fully associate” the country with the EU’s Govsatcom program. “The war in Ukraine shows that our security also depends on space. And the EU has been doing quite a lot. We are ready to support Ukraine where we can support Ukraine,” he added.

Calls to crack down on dependence on foreign providers and boost alternatives to Starlink also come at a time when legislators are negotiating a series of laws that could tame Musk’s ambitions in Europe.

“Ukraine’s dependence on Starlink highlights the vulnerability of European defence systems that rely on U.S. technology, Another reminder that Europe must reduce its dangerous technological dependencies — ASAP,” center-right Finnish lawmaker Aura Salla said on social media.

Policymakers across Europe have been joining forces to curb Starlink’s dominance in low-Earth orbit, where satellites fly close to Earth to deliver faster connections.

“As legislators, we must ensure that European operators are well positioned in the market and limit the dominance of foreign players,” German center-left lawmaker Matthias Ecke said. In Brussels, lawmakers, including Ecke, are backing European telcos gunning for prized satellite frequencies, currently licensed to U.S. operators until next year and eyed by Starlink.

Meanwhile, Zelenskyy said Ukraine was working bilaterally with EU countries to secure more capabilities, citing France. He also expressed hopes that Starlink restrictions could be lifted. “My partners told me there were signals from the White House that they would return these capabilities.”

SpaceX — Starlink’s parent company — didn’t respond to POLITICO’s request for comment.

Ukrainian frontline soldiers are alarmed that Elon Musk’s Starlink satellite service is reportedly being restricted on fast-moving military platforms, warning of severe operational consequences.

“This is comparable to a nuclear strike against us. All operations are on hold. This will cost many of us our lives,” an experienced Ukrainian officer told POLITICO and the Axel Springer Global Reporters Network.

The officer commands a medium-range drone strike unit in southeastern Ukraine. The unit relies heavily on Starlink for the operation and navigation of its American-made Hornet drones, used to strike targets at a range of up to 150 kilometers.

“Since last night, all Starlink and Starshield terminals used by our forces have been subject to a speed limit of 100 kilometers per hour,” the officer said.

POLITICO talked to three frontline soldiers, who all spoke on condition of being granted anonymity, as well as a Ukrainian defense ministry spokesperson and the EU’s top defense official.

The reported restrictions have revived a question Ukrainian commanders have worried about for years: how much of the country’s battlefield communications can rely on a service controlled by a U.S. company.

Ukrainian soldiers say the restrictions have halted some medium-range drone strikes over Ukraine, disrupting attacks on Russian logistics and leaving frontline Ukrainian troops with less support. The scale of the disruption — and whether it was deliberate — remains unclear.

In a comment on X, Musk said: “Starshield systems are owned and controlled by the US government. Any limits on speed or usage are decided by the US military and ultimately POTUS,” referring to the Starshield division of Starlink that is used for military purposes.

“Starlink is a commercial service owned and controlled by SpaceX,” he added. “Usage of Starlink is limited to civilian or defensive activities and cannot be used for offensive military action, as doing so would be inappropriate for a commercial company.”

Mykhailo Fedorov, Ukraine’s former defense minister who has good contacts in Silicon Valley, said late Wednesday: “Starlink connectivity at speeds of up to 160 km/h is being restored. Removing Starshield’s speed limit entirely is now critical for Ukraine’s defense.”

The White House and the Pentagon did not immediately respond to a request for comment.

The restrictions have brought “all medium-range strike operations to a complete halt,” the officer said, including those using mesh-based systems. These rely on a single Starlink-equipped UAV to receive and relay signals to other drones connected through a mesh network, allowing them to strike targets deep inside Russian-held territory or in areas heavily protected by Russian electronic warfare systems.

Such targets include the Donetsk region, the strategically important Novorossiya highway linking Russia to Crimea, the Crimean Peninsula itself, the Kerch area and the Black Sea.

“We can no longer fight effectively to support our infantry on the battlefield. We can no longer strike multiple-launch rocket systems, North Korean-supplied heavy self-propelled artillery positioned deep behind enemy lines, ammunition depots, command centers and other targets,” the officer said.

“The Ukrainian frontline is very much dependent on Starlink-operated mid-strike drones,” Iryna Terekh, CEO of Ukrainian missile-maker Fire Point told POLITICO.

Ukraine’s devastating campaign

For months, Ukrainian medium-range strike drones have inflicted significant damage on Russian logistics in frontline regions. They have disrupted the supply of fuel, ammunition and other military equipment, slowing Russia’s advance. 

The officer said he feared that the Starlink restrictions will give Russian troops a critical opportunity to strengthen their positions.

“Starting today, the enemy will build up its logistics routes to Crimea to reinforce its forces there,” he warned.

Two other Ukrainian frontline soldiers operating ground robots and conventional first-person-view drones in the Donbas confirmed to POLITICO that Starlink services for Ukrainian units were abruptly restricted on Wednesday. 

“On the night of October 14, without prior notice to the Defense Forces, SpaceX unilaterally restricted the operation of Starshield terminals while in motion,” a Ukrainian defense ministry official told reporters in Kyiv. 

The official added that the problems occur at speeds varying from 72 kph to 161 kph, “depending on the specific vehicle and unit.”

The slowdown in Starlink terminals comes as U.S. President Donald Trump exerts fierce pressure on Ukraine to stop attacking Russian refineries. That follows his deal with Russian leader Vladimir Putin to release diesel onto global markets — part of Trump’s effort to reduce fuel prices ahead of next month’s U.S. midterm elections.

“Obviously, this action cannot be a coincidence and is associated with the current political situation,” Ukrainian presidential adviser Serhii Beskrestnov said in a Facebook post.

Asked about the rising American pressure on Ukraine, EU Defense Commissioner Andrius Kubilius said at a POLITICO event on Wednesday: “Political development sometimes makes strange influence. Elections are coming.”

“We are quite dependent on American space capabilities,” Kubilius acknowledged. “The answer to that situation is to develop our own capabilities.”

The Starlink slowdown was condemned by one of Ukraine’s key European allies.

“Hey, @elonmusk, big man, are you playing politics with your products again? As your European customers, we are watching you,” wrote Polish Foreign Minister Radosław Sikorski.

Ukraine depends on Starlink

Since Russia launched its full-scale invasion of Ukraine, Starlink has become central to Kyiv’s war effort. In the spring of 2022, Ukrainian defenders trapped in the besieged city of Mariupol used satellites operated by SpaceX to send messages to the outside world. Ukrainian units relied on the system to coordinate operations during the fierce urban fighting around Bakhmut in 2023.

To this day, soldiers use Starlink to rapidly adjust artillery fire and navigate naval drones during attacks on Russia’s Black Sea Fleet. Ukraine’s former army chief, Valerii Zaluzhnyi, once praised the terminals for their “extraordinary utility.”

That reliance always carried risk. In the early months of the war, Starlink reportedly shut off terminals that were going to be used in a naval attack on the Russian fleet.

But SpaceX has also acted to favor Ukraine. In February, SpaceX shut down access to Starlink terminals being used illegally by Russia, causing immediate chaos. Ukraine then ramped its own use of the terminals.

Kyiv’s armed forces began widely equipping medium-range strike drones with Starlink terminals. Without them, operations would become considerably more complex. The military would, for example, have to calculate terrain elevations and antenna availability itself and install additional communications equipment.

“Starlink allows you not to have to deal with radio physics,” a Ukrainian officer with the call sign Jura said in August. “Starlink allows operators to maintain a live video connection with a drone until shortly before impact.”

Starlink can also provide so-called “synthetic GPS coordinates,” which can help drones navigate when conventional GPS signals are jammed.

But Ukrainian officers feared that decisions made in Washington or in the executive offices of American companies could suddenly weaken Ukraine.

“Many of my colleagues and I myself are very nervous about the question of how we would operate without Starlink,” Jura said. “We have discussed this question several times among our officers: ‘What if Elon Musk or someone at SpaceX switches it off?'”

As Trump has ramped up pressure on Kyiv in recent weeks, Ukrainian officers reported growing problems with Starlink.

One Ukrainian drone pilot, who operates medium-range strike drones, reported severe connectivity problems on Sept. 11 and 12, as well as further disruptions on Sept. 17. He said soldiers from several Ukrainian units had experienced similar problems.

The incidents occurred shortly after U.S. envoys Steve Witkoff and Jared Kushner had concluded visits to Kyiv and Moscow. “After few days, the normal work with Starlink come back. But I believe that was the signal,” the pilot said.

He argued that Russian jamming equipment could not plausibly have produced such geographically consistent disruptions across multiple sectors of the front.

“So that was, I guess, administered from some office,” he said. POLITICO could not independently establish whether the disruptions resulted from deliberate restrictions imposed by the American satellite provider or another technical cause.

The incidents have reinforced concerns among Ukrainian military personnel about their dependence on American-controlled technology.

“The reason is politics and the American option to ‘switch off’ or critically decrease” U.S. systems, the pilot said.

WARSAW — NATO must modernize its military infrastructure to move forces and equipment from Western to Eastern Europe “where we would expect any future conflict,” U.S. Ambassador to NATO Matthew Whitaker said Monday.

Speaking on a panel at the Warsaw Security Forum, Whitaker’s comments came as Washington reviews its military presence on the continent — with the ambassador saying that Europe ranks fourth among Washington’s strategic priorities, behind homeland security, the Western Hemisphere and the Pacific.

He pointed to outdated military bases, fuel supply chains and agreements governing the stationing of American troops in Europe as areas requiring attention under the ongoing U.S. force posture and basing review.

He emphasized the importance of military mobility and “moving things from the west to the east,” citing discussions with EU Defense Commissioner Andrius Kubilius. European officials warn that Russia could be ready to attack a NATO country by the end of the decade.

Whitaker did not announce any decisions to relocate or withdraw American forces. He nevertheless made clear that Washington is reassessing its global commitments to avoid spreading its military resources too thin.

“Superpowers and great global powers have mostly had challenges when they get overextended,” Whitaker said, adding that U.S. President Donald Trump wants allies to become “capable and not dependent.”

“The United States isn’t stepping back. We’re just asking you to step forward,” he said.

Whitaker also criticized countries that are falling short of their defense-spending commitments.

He said he had recently delivered a “very strong message” to political leaders in Czechia. The country’s defense spending for this year is approximately 1.8% of GDP, falling short of NATO’s current 2% benchmark.

European governments must continue strengthening their armed forces, he argued, warning that the continent still lacks many of the capabilities it needs to defend itself.

Kubilius, meanwhile, stressed the need to reduce Europe’s military dependence on Washington, highlighting EU efforts to develop its own drone defenses, satellite communications and surveillance capabilities.

Polish presidential adviser Marcin Przydacz, also on the panel, urged Western European allies to accelerate defense spending while emphasizing that NATO, rather than the EU, must remain responsible for Europe’s collective defense.
