Ukraine continues to struggle with throttling of the speeds at which weapons using the vital satellite communications services provided by the SpaceX Starlink system can operate, one weapons manufacturer tells us it is rethinking whether to rely on it in the future. As we have previously reported, heavy use of Starlink on both sides of the conflict in Ukraine, including as a means of guiding one-way attackers in the air and at sea, has underscored potential risks of exclusive reliance on Elon Musk’s orbital communications networks in critical tactical tasks.
At issue are complaints by Ukrainian officials that “in various sectors of the front, the equipment ceases to function at speeds of 130–161 kilometers per hour.”
A limit on how fast Starlink terminals on vehicles can travel before the feed is cut off in certain areas impacts a slew of weapons and campaigns, especially strikes on Russian logistics behind enemy lines and in the sea of Asov, as well as the control of defensive interceptor drones critical for taking down Russian long-range one-way attack drones, like the notorious Shahed-136.
The following video shows one such Shahed interception.
The limiting of Starlink/Starshield occurred amid deteriorating relations between the Trump administration and Ukrainian President Volodymyr Zelensky. The latest chill between Washington and Kyiv was sparked by the American leader’s claims that Ukraine’s attacks on Russia’s energy infrastructure have reduced the supply of diesel fuel to the U.S. and other nations more than the conflict in the Middle East. Trump was upset Ukraine kept hitting these targets despite his demanding they stop.
Exacerbating this issue, Trump on Oct. 9 announced via his Truth Social platform that he had made a deal to purchase diesel from Russia, pivoting away from a years-old Western policy that placed massive economic pressure on Moscow.
Who gave the order to limit the speeds at which Ukrainian weapons using the Starlink/Starshield system operate is unclear.
“The order to limit a satellite system used by Ukraine for battlefield communications and drone operations came from inside the White House,” Reuters reported last week, citing two U.S. officials and a Western official briefed on the matter. “The officials said leaders at the Defense Department received a message that the SpaceX Starshield service for the Ukrainian military needed to be slowed.”
“No such request was ever made by the president,” a U.S. official told us on Monday.
“There has been no change to Department of War policy regarding intelligence sharing or any capabilities we are enabling Europeans to provide to Ukraine,” a senior Pentagon official responded to our questions about whether the Pentagon imposed the limits and, if so, why.
When we pushed for a more specific response to the Starlink/Starshield concerns, the Pentagon declined comment. However, Tuesday afternoon, Defense Secretary Pete Hegseth said the Pentagon did not order any changes and that Ukraine violated Starlink’s terms of services.
We reached out to SpaceX as well, but the company did not immediately respond. Last week, SpaceX’s founder and CEO, Elon Musk, said that “any limits on speed or usage are decided by the US military and ultimately” Trump. Musk had previously refused Ukrainian requests to use Starlink against targets inside Russia.
The prohibition against using Starlink inside Russia has drastically limited Ukraine’s ability to strike dynamic targets like mobile ballistic missile launchers and hunt for drone launch sites. However, Ukraine has not had to rely on Starlink in its campaign against oil infrastructure or other fixed targets deep inside Russia which upset Trump in the first place.
Tuesday morning, Zelensky spoke with U.S. Secretary of State Marco Rubio and again brought up Starlink/Starshield in addition to other major concerns.
“…the situation with Starlink/Starshield… needs to be restored,” Zelensky urged.
Rubio denied that any assistance was being withheld from Ukraine. Noting that Starlink “is a private company,” the secretary told reporters that Trump is “frustrated…because he doesn’t like to be blamed for things that aren’t true, including accusations that somehow he had ordered intelligence sharing to be cut off. And that’s not true; he’s said that repeatedly.”
This most recent flap isn’t the first time SpaceX and Musk have faced particularly significant criticism over limiting some Ukrainian use of the network. Actions SpaceX took earlier this year to block unregistered Starlink terminals also had major consequences for Russian forces, which were sent scrambling to find alternatives to fill the massive resulting communications gap.
Given the tenuous nature of Ukraine’s ability to use Starlink/Starshield, the Wild Hornets company is reevaluating whether to use the SpaceX system in future endeavors even though, so far, it has experienced few problems with it. Wild Hornets is a major Ukrainian combat drone maker. Among other weapons, it makes the Sting interceptors, designed to defend against Russian Shahed kamikaze drones.
The Starlink/Starshield issue isn’t affecting current operations, Wild Hornets spokesman Mike Orliuk told us Tuesday morning. “Our own communications system provides the basic connection to our interceptors,” he said. “Plus, our technology for remote control of the interceptors can use various sources of internet connectivity. True, the military often uses Starlink for this, but in our case, the terminal doesn’t need to be moved at high speeds (it simply provides a connection between the command center and the ground station to which the interceptor is connected—it’s somewhat similar to cell towers).”

Concerns about the reduction in speeds at which Starlink terminals can operate has Wild Hornets thinking about ditching a future project, Orliuk told us.
“But we understand that there are other types of interceptors,” added Orliuk. “For example, some drones carry a terminal on board and need to fly at high speed with it. In such cases, Starlink’s limitations make their operation impossible. From this point of view, it also makes us rethink some of the projects we’re currently working on. For example, launching interceptors from aerial platforms.”
“We’re keeping an eye on the situation,” Orliuk continued. “For our current operations (connections with ground stations), we can use any source of stable internet connectivity. Therefore, various solutions are possible in different locations. However, for these needs, everything is operating normally with Starlink at the moment. As for our plans with new projects, we don’t have a clear decision yet, but we will be testing alternatives.”
Orliuk declined to provide further details about what “alternatives” could look like.
There are a number of ways the lack of Starlink for extended-range drone operations could be mitigated to a degree, but the persistent, reliable, high-bandwidth and compact capability SpaceX provides has no direct alternative at this time. The use of drones that work as line-of-sight relays, which can be daisy chained together electronically with other airborne relays, with a connection spanning dozens or even hundreds of miles to a ground entry point is possible. You can read about this concept here. The use of swarms of balloons to create an active network over a battlespace and using starlink on those slower moving platforms to relay line-of-sight connections to multiple drones below is another possibility. You can read more about this concept here. But we must stress again, nothing can fully replace Starlink/Starshield and its seamless beyond line-of-sight communications architecture at this time.
“I believe, in any case, depending on a single solution is very risky,” Orliuk proffered. “Especially if you don’t have full control over it. Especially when it comes to something as critical on the battlefield as communications. That’s exactly why our ecosystem is built around our own communications technology and basically is open to various solutions when it comes to internet connectivity.”
As far as military units are concerned, the commander of the Georgian Legion told us that his forces have been affected by issues with Starlink/Starshield even though the main concerns have been about the speeds at which weapons can travel and still have connectivity. The Georgian Legion is fighting in the heavily contested Kramatorsk region of eastern Ukraine.
“We use Starlink a lot because, in this war, reliable communication is essential,” Mamuka Mamulashvili told us. “It helps us stay connected when everything around us is changing. Of course, we’ve learned not to rely on just one system. There are alternatives, like mobile internet, fiber-optic connections, radio and other satellite systems such as OneWeb. But honestly, none of them can fully replace Starlink in Ukraine right now.”
“The problems were not limited to the speed restriction of approximately 160 km/h,” the Georgian Legion commander pointed out. “Starlink connectivity itself was also intermittent, repeatedly switching on and off. This caused communication disruptions across various drone systems, not just those operating at speeds exceeding 160 km/h. As a result, the impact was broader than the restriction on high-speed interceptor drones. Intermittent connectivity created problems for drone control and communications across multiple systems, affecting their reliability and the ability to carry out missions as intended.”
“We had serious communication problems,” Mamulashvili explained. “At one point, our drone operators were struggling to maintain a reliable connection with the drone systems, which disrupted coordination and made it difficult to carry out missions as planned. When you lose the connection between the operator and the drone, you can lose control of the situation in seconds. We managed to adapt, but it definitely affected our work.”
“We have to adapt and find solutions, as we always do,” the commander said. “This war teaches you one thing every day. You can’t depend on a single technology or expect someone else to solve all your problems. You have to be ready for anything and keep moving forward.”
Russian sources, meanwhile, are gloating over the speed limits placed on weapons using Starlink/Starshield, particularly how it is affecting Ukraine’s mid-range drone attacks that have crippled Russian logistics. As we explained in a previous report, Ukrainian units have relied on the SpaceX system to help extend the range of their drones to reach as far as 150 miles into Russian-occupied territory. The SpaceX system is not used to hit targets inside Russia proper.
The following video shows some of these mid-range attacks.
“Disabling or slowing down Starlink has significantly reduced the enemy’s ability to launch medium-range drone strikes along the ‘Novorossiya’ highway,” influential Russian milblogger Vladimir Romanov reported. The highway, also known as the R-280, is a key link between cities in occupied southern Ukraine and the occupied Crimean peninsula. The road has been a frequent target of Ukraine’s mid-range strike campaign.
“The success of these strikes depends on the Ukrainian Armed Forces’ access to American satellite communication,” Romanov noted. “For the past six months, the Ukrainian Armed Forces have been attacking civilian transport – trucks, cars, and buses – exclusively through the use of ‘Starshield.’ This means that, for the past six months, American military satellite infrastructure has been used to carry out terrorist acts against Russian civilians, and so on. In other words, the United States is still directly involved in the war with Russia!”
As for how widespread worries among Ukrainian weapons manufacturers are, Orliuk suggested that Wild Hornets is not alone. He said he has spoken with other companies relying much more heavily on Starlink/Starshield who have expressed concerns. He pointed to growing interest in the European Eutelsat satellite constellation as an example of companies seeking options, but noted that “of course, creating something like Starlink won’t be easy.”
We’ve reached out to the Ukrainian Brave1 defense technology incubator and the National Association of Ukrainian Defense Industries (NAUDI) for additional insights into how this issue is affecting Ukraine’s defense manufacturing base.
It will be interesting to see if other Ukrainian weapons companies also consider scrapping plans to rely on Starlink in the future and what architectures will emerge at least as a backstop to it.
