SpaceX blocks Russian Starlink access in Ukraine, Kyiv calls it a ‘catastrophe’ for Moscow

Kyiv: SpaceX has implemented new measures to restrict Russian access to Starlink satellite internet services in Ukraine, while maintaining connectivity for approved Ukrainian terminals through a whitelist system. The move follows repeated claims from Kyiv that Russian forces were using Starlink devices obtained through black market channels to coordinate troop movements and guide long-range strikes.

Ukraine has long warned that Russian troops were deploying Starlink terminals in combat zones despite US sanctions that prohibit SpaceX from selling the equipment to Russia. Ukrainian officials have reported finding Starlink systems in downed reconnaissance drones and, more recently, in long-range strike drones.

Under the new system, SpaceX has disabled broad connectivity in contested areas while allowing registered Ukrainian terminals to function. Ukrainian authorities have urged military units, businesses and civilians to register their devices through the country’s DELTA battlespace management system. Defence Minister Mykhailo Fedorov confirmed that the whitelist is updated daily and said the first batch of approved terminals is already operational.

Elon Musk also called on Ukrainian users to register their terminals to avoid disruptions. Reports indicate that connectivity has been restricted for devices travelling faster than 75 kilometres per hour, a measure aimed at limiting the use of Starlink in guiding attack drones.

Ukrainian military-linked commentators described the development as a significant blow to Russian operations. Some claimed Russian units were experiencing widespread outages along parts of the front line, potentially affecting their ability to coordinate ground assaults and adjust artillery fire.

Russian military bloggers acknowledged temporary disruptions, with some urging the Kremlin to accelerate the development of domestic communication alternatives. Concerns were raised about the lack of ready substitutes for Starlink, with suggestions that forces might have to rely more heavily on fibre optic systems for frontline communications.

However, not all Ukrainian users were unaffected. Some troops reported service interruptions if their devices had not been promptly registered under the new system.

The broader impact of the Starlink restrictions on the conflict remains uncertain. Analysts note that satellite connectivity has played a critical role for both sides in maintaining battlefield coordination, drone operations and real-time communication.

Ukrainian officials have publicly thanked SpaceX for the changes, arguing that restricting Russian access could help limit the use of Starlink-enabled drones in attacks. The development marks a new technological dimension in the ongoing war, highlighting how satellite communications systems have become central to modern military strategy.
