Ukrainian forces have reported the sudden loss of satellite communications during high-speed drone operations after SpaceX imposed new restrictions on its military-grade Starshield service. The disruption revives questions over American control of Ukraine’s battlefield communications and follows earlier controversies involving Elon Musk’s intervention in Ukrainian military operations.
Ukraine’s armed forces have reported serious disruptions to drone operations after Elon Musk’s SpaceX introduced new restrictions on its Starshield satellite communications service overnight on 13–14 October. The changes reportedly caused Ukrainian unmanned aircraft to lose connectivity when travelling faster than 160 kilometres per hour, forcing the abandonment of several military missions.
The restrictions were confirmed by Serhiy Beskrestnov, an adviser to President Volodymyr Zelenskyy on defence technologies, who said Ukrainian forces had received no advance warning. According to his account of the disruption, the new limit of 100 miles per hour applies to Starshield, the military communications service developed by SpaceX for government and defence applications.
Serhiy Sternenko, a prominent Ukrainian volunteer and former adviser to the defence minister, was among the first to report the problem. In a statement published on Wednesday morning, he said satellite connections had begun disappearing once drones exceeded the new speed threshold, disrupting several important missions. Sternenko suggested that the decision might have been taken at the request of President Donald Trump’s administration, although no evidence establishing such an instruction has been made public.
Four Ukrainian military personnel speaking to Ukrainska Pravda independently reported problems with Starshield. One commander provided footage purportedly showing two Ukrainian drones losing their satellite connections during flight and becoming unable to complete their missions.
The restrictions do not appear to affect ordinary Starlink terminals operating within their existing speed limits. However, military-grade Starshield connectivity allows Ukraine to operate certain unmanned systems at considerably higher speeds, including aircraft conducting long-range missions against Russian military and industrial targets.
Previous disputes over Starlink access
The latest interruption is not the first occasion on which SpaceX has limited Ukraine’s military use of its satellite network. Since Russia launched its full-scale invasion in February 2022, Starlink has become an essential component of Ukrainian battlefield communications, supporting frontline command systems, artillery coordination and unmanned operations.
In September 2022, during Ukraine’s counteroffensive in the south, Starlink communications failed in areas where Ukrainian forces were attempting to advance against Russian positions. A subsequent investigation published in July 2025 reported that Musk had personally ordered the suspension of service across parts of the battlefield, including areas around Kherson.
The interruption reportedly affected reconnaissance, artillery targeting and communications between military units at a critical stage of the operation. The investigation raised questions about the ability of a private technology provider to influence military operations through decisions governing access to its infrastructure.
Another controversy emerged in September 2023, when Musk acknowledged refusing a Ukrainian request to activate Starlink coverage near Sevastopol in Russian-occupied Crimea. Ukrainian forces had intended to use unmanned naval vessels against Russia’s Black Sea Fleet.
Musk argued that enabling the operation could have made SpaceX complicit in a major escalation of the war. His explanation also challenged earlier accounts suggesting he had actively switched off an existing connection, rather than declined to activate coverage in the requested area.
In February 2023, SpaceX president Gwynne Shotwell had already confirmed restrictions on Ukrainian drone operations, explaining that the company had not intended its commercial communications network to be used directly as a weapon.
Military dependence and American leverage
The Pentagon attempted to establish a more formal relationship with SpaceX in June 2023, contracting the company to provide satellite communications to Ukrainian forces. However, the contractual arrangements and the extent of American government authority over operational restrictions have never been fully disclosed.
Ukraine subsequently gained access to Starshield, which SpaceX describes as a secure satellite network intended specifically for national security applications. Unlike the commercial Starlink service, Starshield is designed to support government communications and other sensitive operations.
The latest restrictions therefore concern a service intended for military use rather than the civilian network at the centre of earlier disputes. Their introduction without advance notification has renewed concerns about Ukraine’s dependence on communications infrastructure controlled outside the country.
The timing is particularly sensitive as Washington and Kyiv continue to disagree over Ukrainian strikes against Russian energy facilities and the terms of a possible ceasefire. Ukraine has maintained that attacks against Russia’s oil industry are part of its campaign to reduce Moscow’s ability to finance and sustain the invasion.
Nevertheless, there is currently no independently established connection between those diplomatic disagreements and SpaceX’s decision to impose the new speed restriction. Neither a technical explanation nor evidence of an instruction from Washington had been publicly established when the disruption was reported.
For Ukrainian commanders, the immediate problem is operational. High-speed unmanned aircraft depend on reliable communications for navigation, mission management and the transmission of information. A restriction introduced without warning can render previously functioning systems ineffective in the middle of an operation.
The incident has exposed a persistent vulnerability in Ukraine’s military communications arrangements: even where the necessary aircraft, operators and mission capabilities are available, their employment may remain subject to restrictions imposed by an external satellite operator.
