A 100 mph Starshield cap has Kyiv seeking answers from SpaceX while Musk points to Washington
Ukraine's defence adviser Serhiy Beskrestnov says an unannounced 100 mph speed cap on Starshield's military package caused several missions to fail. Accounts of who imposed it conflict, so supplier risk and political risk cannot yet be separated.

Drones or missiles at more than 100mph lost guidance; logistics, reconnaissance and signal relaying were reduced. Beskrestnov says SpaceX set the limit. Musk says the U.S. military and POTUS decide. Reuters's sources cite the White House; a senior official denies a presidential request.

What happened
- Al Jazeera reported that drones or missiles flying faster than 100 mph lost their guidance connection under the cap.
- Musk wrote on X: "Starshield systems are owned and controlled by the U.S. government. Any limits on speed or usage are decided by the U.S. military and ultimately POTUS."
- Reuters, citing three US officials, reported that the decision came from inside the White House.
- A senior US official told TIME: "No such request was ever made by the President."
- Ukrinform reported Thursday, citing Ministry of Defense sources, that Starshield service had resumed.
Why it matters
- What doesn't add up contradiction Only one of four accounts has SpaceX setting the cap, while Musk and Reuters's sources place the decision with the US government, so a single-vendor risk is asserted but not shown.
- What's now possible capability A ceiling at 100 mph hits fast drones and missiles first, so whoever sets it holds a selective switch that a general outage would not give.
- Who has to decide decision Kyiv has to choose whether to press SpaceX, which it is reportedly doing, or Washington, where Musk and Reuters's sources place the decision.
- Who's exposed exposure Officials said the cap also reduced front-line logistics, reconnaissance and signal relaying, so a throttle with no notice disrupts planning across several functions at once.
Mark Hilborne, a senior lecturer in defense studies at King's College London, told TIME why the loss matters beyond bandwidth: "In and of itself, satellite communications are not military technology, but it enables the military to communicate and amass a real-time, multi-domain picture of the battlefield, which some argue nobody else actually has at this stage." [11] Starshield relies on the Starlink network, and Ukrainian forces have recently used it to strengthen drone strike missions and air defenses [10]. The sources do not report Ukraine moving any traffic to another provider.
We think the dependency is real. It sits at two layers, the network SpaceX runs and the rules set on top of it (the second being the one the sources dispute). There are three ways this goes. Washington set the cap, as Musk and Reuters's sources say [13][14], and then the risk is political with SpaceX as the conduit. SpaceX set it, which is what Beskrestnov is reported to have said on Telegram [4], and then a commercial supplier throttled a customer at war. Or it was a fault: Zelensky said he hoped the restriction was only a "mistake", perhaps "a huge technical problem" at SpaceX [16].
The political reading rests on Beskrestnov, a military technology expert who advises Zelensky, who said the restrictions were "related to the current political situation" and did not offer further details [1][12]. The backdrop is a dispute over diesel. Zelensky has been vocal in his disapproval of Trump's plan to import it from Russia [18], and Trump called Ukraine's fresh strikes on Russian refineries a "disgrace" in an interview that aired Thursday [19]. Zelensky suggested he believed Starlink had been slowed down to damage him [17].
The accounts also differ on detail. Al Jazeera dates Ukraine's first statement to Tuesday [8] and TIME to Wednesday [7]. TIME puts the cap on devices over 100 mph using Starshield's "military package" [1][2], while Al Jazeera puts it on Starlink terminals [4]. We would drop the political reading if SpaceX or the US military documents a fault, and the vendor reading if a named US official confirms the limit as a US decision.
What to watch
- Whether the White House responds to TIME's request for comment on Reuters's report that the decision came from inside it.
- Whether SpaceX answers Kyiv's request for clarification on why service was disrupted between Tuesday and Wednesday.
- Whether Ukraine's Ministry of Defense confirms the Ukrinform report that Starshield service has resumed.
