Ukraine has welcomed Elon Musk's quick action to limit Russian use of Starlink satellites for drone attacks. Defence Minister Mykhailo Fedorov called Musk "a true champion of freedom and a true friend of the Ukrainian people." Russian drones connected to Starlink are linked to deadly attacks, including one that killed six on a passenger train. Musk confirmed on X (formerly Twitter), "Looks like the steps we took to stop the unauthorised use of Starlink by Russia have worked. Let us know if more needs to be done." Starlink, a SpaceX service, provides high-speed internet worldwide and has operated in Ukraine since Russia's invasion in 2022. Russian drones are hard to shoot down as they fly low, can’t be jammed easily, and are remotely controlled in real time. Reports say SpaceX introduced a 75kph speed limit on Starlink terminals moving in Ukraine. Since Russian drones fly faster, this stops them from using Starlink for control. Ukraine plans a whitelist to approve Starlink terminals; unregistered devices will be disconnected, Fedorov said. The Ukrainian government is working with SpaceX on this. Russian military bloggers warn that these limits may affect Russia's frontline internet too. Fedorov first asked Musk for help in February 2022 when Russia invaded. Musk enabled Starlink the same day and promised more dishes. However, Musk later restricted access in Crimea to avoid SpaceX being seen as part of the war. Musk has criticized Western funding for Ukraine but insisted Starlink will never be turned off. "My Starlink system is the backbone of the Ukrainian army," Musk said, warning the front line would collapse without it. Despite past tensions, Fedorov praised Musk last week for providing critical support early in the war. Now Ukraine’s defence minister, Fedorov embraces data-driven and cyber warfare strategies and aims to cooperate closely with Silicon Valley companies to strengthen Ukraine's defence.
