Four senior Democratic US senators have demanded answers from SpaceX over unexpected restrictions on Ukraine’s access to Starlink and Starshield satellite technologies, warning that the disruptions undermined Ukrainian military capabilities during intense Russian attacks and endangered both civilians and US personnel in the country.
Senators Jeanne Shaheen, Richard Blumenthal, Sheldon Whitehouse and Chris Coons raised concerns in a letter to SpaceX Vice President of Legal Christopher Cardaci, seeking clarification about the company’s involvement in restricting Ukraine’s access to critical satellite services.
The lawmakers said the restrictions, reported by Ukrainian military officials on October 14, occurred without warning as Russian forces continued their bombardment of Ukrainian cities and infrastructure.
According to the senators, Ukrainian officials reported that access to Starshield had been restricted for devices travelling faster than 100 miles per hour, or approximately 160 kilometres per hour.
The limitation was particularly damaging to Ukraine’s drone operations, which rely on satellite connectivity for battlefield coordination and other military capabilities.
“On October 14, 2026, without warning and amidst a barrage of attacks from the Russian military, Ukrainian officials reported unexpected restrictions to Starlink and Starshield technologies that the Ukrainian military relies upon for critical capabilities on the battlefield,” the senators wrote.
The lawmakers said recent reports indicated that US government officials had made the decision to impose the restrictions and that access to some services had subsequently been partially restored.
However, they warned that the disruption had already had serious consequences for Ukraine’s defence capabilities.
“The hasty and life-threatening limitation of Ukraine’s access to Starlink and Starshield has already had grave consequences for the Ukrainian people,” the letter said.
The senators also warned that the restrictions had weakened Ukraine’s ability to counter Russian drones, potentially placing American personnel in the country at greater risk.
Musk and Trump deny involvement
The letter raises questions about the respective roles of SpaceX and the US government in controlling access to Starshield, a military and intelligence satellite communications system developed by SpaceX.
SpaceX Chief Executive Elon Musk has previously said that Starshield systems are owned and controlled by the US government and that restrictions on their speed or use are determined by the US military and ultimately the president.
Both Musk and US President Donald Trump have denied involvement in restricting Ukraine’s access to the technologies.
Nevertheless, the senators noted that SpaceX owns and operates the underlying Starlink network and infrastructure on which certain Starshield services depend.
They argued that the arrangement raises serious questions about who ultimately has the authority to interrupt or modify satellite services during military operations or national security emergencies.
“These circumstances raise important questions about the respective technical, contractual, and operational authorities retained by SpaceX and the U.S. government,” the senators wrote.
They also questioned the extent to which SpaceX could independently restrict access to either Starlink or Starshield during active military operations.
Senators set November 2 deadline
The lawmakers have given SpaceX until November 2, 2026, to provide detailed information about restrictions imposed on Ukrainian assets between October 10 and October 15.
They are seeking records identifying the capabilities affected, when each restriction took effect and how long it remained in place.
The senators also want to establish who was involved in making the decisions and whether SpaceX received instructions from US government officials.
If the company was not directly responsible, it must explain when and how it was notified and how the relevant directives were communicated.
The inquiry also extends to Germany, which funds Ukraine’s access to Starlink services.
The senators asked SpaceX to disclose when it notified the German government of the decision to reduce the capabilities available to Ukraine, citing the company’s contractual obligations to Berlin.
In addition, the lawmakers demanded copies of communications between SpaceX and US federal agencies concerning restrictions on Starshield, as well as relevant government contracts and amendments.
They are seeking clarification on who has the legal authority to revoke or modify Ukraine’s access to Starshield and whether SpaceX can refuse, alter or delay restrictions requested by the US government.
The requested documentation also includes contracts related to Starshield operations supporting Ukraine and countries along NATO’s eastern flank.
The senators said they were prepared to review classified information through appropriate secure procedures if necessary.
Restrictions raise broader national security concerns
The dispute comes as Ukraine continues to defend itself against sustained Russian missile and drone attacks targeting cities, energy facilities and other civilian infrastructure.
Satellite communications have become a critical component of Ukrainian military operations, supporting frontline communications, drone deployments, command coordination and efforts to intercept Russian aerial threats.
Starlink has been widely used by Ukrainian forces since Russia launched its full-scale invasion in February 2022.
Starshield, meanwhile, is a specialised military and intelligence system developed by SpaceX that incorporates Starlink technology while providing additional capabilities, including enhanced encryption.
The senators argued that unexpected restrictions on such systems during active combat operations could have immediate consequences for Ukraine’s ability to protect its territory and population.
They also warned that the incident raises broader concerns about US national security and the responsibilities of private technology companies providing essential military infrastructure.
The central question remains whether SpaceX independently imposed the restrictions, acted on instructions from US authorities or was otherwise involved in implementing the changes.
The senators are seeking to establish the circumstances surrounding the disruption and determine who was responsible.
Their intervention adds to growing scrutiny in Washington over the reliability of critical US-provided technologies supporting Ukraine’s defence against Russia.
With Ukraine continuing to face large-scale Russian attacks, the lawmakers have stressed that ensuring uninterrupted access to essential battlefield communications is a matter of both Ukrainian and American national security.
