SpaceX founder Elon Musk says that if Ukraine fires through Starlink, Russia would be entitled to shoot the network down. That is why Starlink must remain a civilian operation and cannot be used for outright offensive strikes that would put its very existence at risk.

The warning lands in the middle of a fight over Musk’s own hand on that network. Weeks ago, his company unexpectedly throttled the service Ukraine’s drones depend on amid US President Donald Trump diesel deal with Russia, which led to the disruption of a few operations on the front.

The US Treasury authorized the sale, delivery, offloading, and import of Russian-origin diesel fuel, effectively suspending sanctions on that trade until 7 April 2027, the Office of Foreign Assets Control (OFAC) said on its website on 9 October.

The diesel deal combining intelligence halt and military Starlink, with pressure on Ukraine to make a quick peace deal, has angered both Democrats and Republicans ahead of the US elections on 3 November, where Democrats could win.

Meanwhile, a Ukrainian official interprets Musk's talk of strikes as an attempt to build an alibi before a possible investigation into that decision.

A civilian network, or a target

Musk was responding to a post warning that if Starlink shifted from a civilian network into a military system, Russia could treat it as a target for retaliation, and that destroying satellites in orbit could scatter enough debris to make space unusable for years or centuries.

“An adversary blowing up Starlink satellites would create a domino effect of destruction that would generate a vast field of debris, making space unusable," he writes.

When the shield and the warnings failed together

Overnight into 14 October, SpaceX quietly capped the speed of Starshield, the military version Ukraine’s drones run on, without telling Kyiv. Ukrainian units said the limit broke a series of missions, with connections dropping mid-flight and leaving drones hard to control.

At the same time, President Volodymyr Zelenskyy said Ukraine relies on the network for air defense, not attack, to intercept the Russian drones Moscow sends to its cities, and that once the speed was cut, his forces could no longer stop some of them as effectively as before.

Simultaneously, Ukraine's other American lifeline also went dark: for about three days, the US stopped passing the intelligence that warns of Russian ballistic launches. On 12 October, Russian ballistic missiles hit Kyiv before the air-raid alert reached people, with no advance data from partners. In a strike during that window, three people were killed in the capital, the sirens sounding only after the blasts.

A Ukrainian official sees alibi-building

Meanwhile, Andrii Kovalenko, the ex-head of Ukraine’s Center for Countering Disinformation, read Musk’s statement as self-protection rather than physics

“Musk, having taken responsibility for the restrictions on Starlink and Starshield for Ukraine, is now trying to build himself an alibi before a possible investigation into that decision,” he wrote.

He said that regardless of who was behind the idea of restricting Starlink and Starshield access for Ukraine, it represents a strategic setback for the US in the long run, as it risks portraying the country as an unreliable partner that may fail to honor its commitments.

"Europe purchases around 60% of its imported weapons from the US. Trust in the US as a security guarantor directly supports sales for American defense companies. Moves like this only undermine that trust and encourage European countries to develop their own systems," he said.

The US has sent a message that its guarantees may not be reliable and that even paid-for services can be subject to political decisions, Kovalenko stressed.

• A Ukrainian drone maker was surprised by how much explosive weight soldiers loaded onto one of its drones.
• A drone's payload is limited by the weight of its battery, camera, and other equipment.
• Drone makers push technical limits, but Ukrainian soldiers often go even further.

A major drone maker said Ukrainian soldiers surprised it by packing one of its drones with more explosives than the company ever thought it could carry.

When loading up an attack drone with explosives, combat units are limited by how much weight it can carry and still fly. Batteries, cameras, and other essential equipment also take up some of that capacity. That doesn't stop soldiers from pushing the equipment to its limit.

"One of the most surprising videos I've seen recently is that one of the units has managed to put the huge explosive part on our drone," Oleg, an executive at TechEx, told Business Insider.

The drone was carrying "something like five or seven kilos, and they managed to fly into the building and put it completely to the ground with one single FPV."

"I was like, 'How do you literally put this amount of explosives on one single FPV?' But it managed to carry this on and did the mission," the TechEx exec said, speaking on the condition that he be identified only by his first name for security reasons.

TechEx lists a maximum payload of two kilograms for three of its NATO-codified fiber-optic drones: the Stalker XO-10 China-Free, Stalker XO-15 MAX PRO, and Stalker XO-13.

Weight is a major constraint for Ukraine's drone makers, who are constantly trying to accommodate more firepower and bigger batteries, as well as heavier weapons and cameras. It's a constant trade-off, with every gram mattering.

Soldiers fighting for survival often push beyond advertised limits. Last year, a sergeant major in a heavy bomber company told Army Inform, Ukraine's defense ministry media, that while a Bat drone can fly up 8 kilometers and carry up to 12 kilograms, his unit pushed it to fly a little farther and carry a little more.

Weight is an important consideration for TechEx drone development. The company advertises its "ultralight fiber optic reel" as one of its product advantages. Last year, Ukraine's Ministry of Defense characterized TechEx's Stalker series as having a "record-low spool weight among Ukrainian fiber-optic drones."

The struggle with weight is particularly acute for fiber-optic drones because, in addition to gear like batteries, they have to carry the spool containing the fiber-optic cable that trails behind them, maintaining a connection with the drone operator. The cable makes them resistant to enemy jamming, but the added weight limits how many explosives they can carry. The cable spool can weigh several kilograms on some drones.

Olha, a TechEx representative, told Business Insider that the company developed its own technology to reduce spool weight, making "tiny tweaks and changes" to how the spool is assembled and the fiber is wound into it. Those adjustments allow the company to keep the spool lightweight while maintaining a stable connection and minimizing the risk of the cable breaking during flight.

The company needs the "perfect balance" to make sure it stays reliable and durable, as not all drone pilots have a wealth of flying experience, Oleg said.

The company faces trade-off decisions. Extending the range of its fiber-optic drones, for instance, would require larger cable spools, potentially leaving less room for explosives, Olha said. But not every drone needs a heavy payload. For some, speed and agility matter more.

Ukraine's soldiers often surprise the manufacturers of their weapons with how they use and adapt their gear, with troops sometimes repairing and modifying equipment near the front lines and experimenting with new tactics.

Kuldar Väärsi, the founder and CEO of Estonian ground robot maker Milrem Robotics, previously told Business Insider that Ukrainian soldiers used the company's technology in ways it was not expecting, including adding and attaching things to the robots. "Ukrainian troops are really creative, and they really find very simple ways how to get even more out of the equipment," he said.

How gear is used in the field often informs how Ukraine's defense companies update and modify their products. Soldiers give feedback to firms like TechEx every day, and companies send their own employees close to the fight to gather feedback and make changes.

Oleg said that TechEx receives direct feedback from soldiers constantly, resulting in weekly changes to its products. Without changes, a product in Ukraine "within three months, it will be outdated, and nobody will use it, because the industry is moving extremely fast," he said.

TechEx encourages soldier experimentation, including by making its drones with parts that are interchangeable. Soldiers can swap components to repair damaged drones or combine parts to create configurations the company never designed.

"Part of what I think TechEx is really great at is the ability to customize," Olha said.

• Drones in Ukraine act as flying communications bridges between operators and mission drones.
• They repeat the operators' signal to allow drones to fly farther while staying connected.
• The signal-repeating drones make other drones more resistant to Russia's electronic warfare.

Ukraine has created drones that act as flying relay towers, allowing its drones conducting missions to fly farther while making them harder for Russia to jam.

In a war where drones gather intel and account for more than 95% of Russia's front-line losses, Ukraine wants its operators to keep control of their drones over longer distances with stronger signals that are harder for Russia to break.

One solution is the signal repeater drone, a flying signal booster that operates between a pilot and a mission drone, relaying commands to the aircraft and sending back video and intelligence to the operator. Able to fly much higher than a ground antenna, airborne repeaters can extend a drone's range and help preserve the connection under pressure.

It increases the mission drone's operational range by extending how far it can fly while staying connected to its pilot. It's a similar principle to how wifi repeaters work.

Ukrainian arms maker Twist Robotics makes a signal-repeating drone, born from its Saker Scout drone.

Rostyslav Olenchyn, the company's co-founder and chief information officer, told Business Insider that the drone was widely used for reconnaissance and strike operations, but this war changes rapidly, with arms and warfighting technology quickly becoming obsolete. And without updates, this drone was at risk of falling victim to that pattern in the cat-and-mouse technology race.

Drones needed to be effective at longer ranges, and the Saker Scout's range was "not enough" for many missions. So, the drone was redesigned "for another objective. It became the signal relay station," Olenchyn said.

The Saker Scout, able to also be used in other combat roles, can extend the operational range of drones by more than 50 kilometers, according to the company.

The concept of using aircraft as signal middlemen isn't new. Militaries have used helicopters and planes to relay communications between assets and forces disconnected by the terrain, though usually troops rather than drones. These crewed aircraft, however, struggle to operate over Ukraine, but while such air assets are few and far between, drones are prolific.

Large crewed aircraft cannot "necessarily survive in the heavy saturated air of the battlefield," where drones and air defenses are a threatening presence, Olenchyn said. "So the small, versatile platform was a solution." He said that serial production of the Saker Scout with this function started in 2023.

The company's strike drone, the Signal Hunter, can also be used as a relay.

Other Ukrainian companies are also working in the space, with some updating existing drone types and some designing new ones. Roboneers, for example, developed a version of its Wardog drone that can carry relay equipment weighing up to three kilograms, and Skyriper makes the Skyriper-R Airborne Repeater, a dedicated drone with the single function of acting as an airborne repeater.

Volodymyr Zinovskyi, the CEO of the Ukrainian defense firm TAF Industries, told Business Insider that his company started making relay drones last year at the request of units, describing the technology as going from optional to essential.

Brave1, Ukraine's state-backed innovation platform, wrote last year that "the use of UAVs over long distances or in difficult terrain requires the use of repeaters - special devices that help increase the range of a stable signal several times."

Some Ukrainian drones are built for this relay mission, while others can be fitted with add-on repeater equipment.

Beyond overcoming geographical challenges, airborne repeaters also help counter Russian electronic warfare by strengthening the communications link between operators and mission drones, making it harder to disrupt, though Russia can still target the relay itself.

An analysis published by the Center for Strategic and International Studies, a US think tank, last year described the creation of relay systems as a response to growing electronic warfare tactics, including the ability that both sides have to trace drone control signals back to their source for strikes on operators, priority targets in this war.

Dmytro "Liber" Zhluktenko, a former drone operator who now serves as a lessons-learned analyst with Ukraine's 413th Unmanned Systems Regiment "RAID," told Business Insider that Ukrainian forces are "keeping somewhat a stable radio link by mass utilizing signal repeaters."

He said that some uncrewed repeater aircraft are fixed-wing drones, while some are repurposed bomber-type drones. Instead of bombs, it just carries the signal repeater," he said.

"We optimize those signal repeater carriers to just stay in the air for an extremely long time, like one hour plus," he said. "That's their only job: to be in the air." Working with strike drones, they give operators a "great radio link over the target."

Oleksiy, the commander of the 2nd UAV engineer platoon of the International Defense Legion of Ukraine, told ArmyInform, the official information agency of the Ministry of Defense of Ukraine, last year that his unit uses repeaters on drones to expand the radio horizon of the drones they want to use and fly further to target Russia.

Russia is using the technology too, including to help attack drones fly deeper into Ukrainian territory.

And these lessons aren't limited to the Ukraine war. The US military is also experimenting with ways to extend drone operations and keep operators connected from farther away. The Marine Corps, for instance, has experimented with using helicopters as FPV motherships, as well as handing off control after launch.

Though different from Ukraine's airborne repeater work, both address a similar battlefield problem, which is that drones are only useful if operators can launch them, control them, and keep receiving information at tactically relevant distances.

Olenchyn said that updates, like the signal repeating ability, are critical in combat. He said that every two weeks, the company has "a new update, new kinds of techniques, new kinds of drones or functionality which are released."
