In February 2026, Starlink began cutting off every terminal in Ukraine that was not on a whitelist. The aim was to stop Russian forces using the network. Elon Musk posted on X: “Looks like the steps we took to stop the unauthorized use of Starlink by Russia have worked.”
The episode, analyzed by the intelligence newsletter Alcon, showed how far both sides have come to depend on one privately run system.
How Starlink got to Ukraine
Russia knocked out much of Ukraine’s communications infrastructure at the start of the 2022 invasion. On February 26, Ukrainian minister Mykhailo Fedorov asked Musk on Twitter for help. Musk agreed. SpaceX activated service across the country, and the first shipment of terminals arrived on February 28. SpaceX president Gwynne Shotwell has said the company had been negotiating to switch on service in Ukraine a month and a half before the invasion.
Service was free for the Ukrainian military at first. By June 2023 the US Department of Defense was involved. According to Alcon, Musk had raised concerns about sustaining free wartime access, and US intervention led to a formal Department of Defense contract that year.
Civilians used it too. Hospitals received 600 terminals in a month. Ukrainian officials declared in 2023 that Starlink had become the core of the country’s communications. Thousands of troops cut off in Mariupol used it to publish photos and videos before they surrendered in May 2022.
Friction over offensive use
On the battlefield, Alcon listed uses that included coordinating isolated units, passing drone-collected intelligence to artillery, and flying reconnaissance and strike drones. It said detection-to-engagement times shrank to 30 minutes or less.
That use strained relations with SpaceX. The company worried about escalation if the network supported offensive operations. It set geofencing limits and refused to extend service for certain operations, including a planned naval drone strike in Crimea. Wikipedia’s account says Musk denied a Ukrainian request in 2022 to extend coverage up to Russian-occupied Crimea because doing so would have violated US sanctions, and that media reports wrongly described this as Musk “turning off” Starlink there.
Russia’s terminals
US sanctions bar official sales to Russia, yet Russian units used thousands of terminals. Reports of Russian use surfaced in February 2024. By September 2024 Russian Shahed drones were reportedly fitted with Starlink antennas. In December 2025 the modified Molniya-2 drone was reportedly equipped with Starlink parts that stretched its range from 30 km to 230 km.
Ukrainian officials judged that Russia obtained terminals through third-party suppliers and battlefield capture. Serhiy Beskrestnov, an adviser to Ukraine’s defense minister, said Russian operatives offered cash to civilians in Ukrainian-held territory to register terminals in their own names. On February 17, 2026, Lt. Gen. Valery Tishkov acknowledged Russian units were using terminals on the front line. He said the use was limited to “individual” units and “primarily to mislead Ukrainian forces.”
The whitelist requires every terminal to be verified and registered. Civilians and businesses can sign up at service points or online. Military units use a separate process.
What the cutoff changed
Ukrainian forces made gains at the same time. President Zelensky said they had liberated 300 square kilometers in the south, while the Institute for the Study of War assessed at least 168.9 square kilometers since January 1, 2026. In a February 20 interview with AFP, Zelensky suggested his forces were “taking advantage” of the connectivity disruptions. Alcon cautioned that direct evidence tying the whitelist to battlefield results is limited and that it was probably one factor among several.
Russian forces are expected to adapt. Alcon reported they were installing antennas and signal amplifiers in central Myrnohrad and, according to pro-Ukrainian hacker groups, using cellular towers in Belarus to route signals for drone strikes. On February 12, Russia’s Foundation for Advanced Research Projects claimed a first flight of the Barrage-1 stratospheric platform, designed to carry 5G communications equipment. Alcon called its effectiveness questionable.
