A bipartisan group of U.S. senators has demanded an urgent investigation into reported speed restrictions on Ukraine’s Starlink satellite internet network. Source: bbc.co.uk.
What Happened
On Tuesday night, Ukraine temporarily limited drone speeds to 100mph (160km/h) to maintain Starlink connectivity.
Any weapon system exceeding that speed lost internet access. This disrupted Ukraine’s ability to guide drones to Russian targets and monitor threats in real time.
On Friday, President Volodymyr Zelensky confirmed Starlink services were still being restored, but said the speed had not yet returned to pre-restriction levels.
Senate Letter and Concerns
The senators, including Democrats Jeanne Shaheen and Richard Durbin, and Republicans Thom Tillis, Susan Collins, and John Cornyn, sent a letter to the U.S. defence department inspector general.
They express ‘grave concern’ about reports of degraded performance between October 12 and 14.
The letter states that such restrictions ‘degraded Ukraine’s ability to conduct defensive operations’ against Russian drone and missile attacks on civilian infrastructure.
It also highlights incidents where U.S. military and diplomatic personnel were unable to reach designated bunkers during Russian air raids.
The senators say these incidents ‘require immediate investigation’ due to potentially deadly consequences.
Who Is Involved?
Starlink is a civilian service operated by SpaceX, owned by Elon Musk.
Starshield, a separate system, is designed for government and military use and is also operated by SpaceX. Musk has suggested that Starshield is under U.S. government control.
On Wednesday, Musk wrote on X: ‘Starshield systems are owned and controlled by the U.S. government. Any limits on speed or usage are decided by the U.S. military and ultimately [the U.S. president].’
However, a U.S. official told the BBC that ‘no such request was ever made by the president [Donald Trump]’ to impose speed limits on Starlink.
Why It Matters
Starlink is critical for Ukraine’s battlefield operations. It enables real-time drone guidance, threat warnings, and secure communication.
Disruptions could compromise defensive capabilities and endanger both Ukrainian and U.S. personnel.
The incident raises questions about coordination between U.S. government systems and Ukraine’s use of commercial satellite services.
Background: How Starlink Works
Starlink uses a network of low Earth orbit satellites to deliver internet to remote and conflict zones.
It is not designed for military command or weapon control, though it has been adapted for battlefield use.
Its civilian nature means it is not subject to direct military command, unlike Starshield.
Limitations and Open Questions
While the source confirms the existence of speed restrictions and the senators’ concerns, it does not establish whether the limits were imposed by Ukraine or by a third party.
There is no verified evidence that the U.S. government directly ordered the restriction.
Ukraine has accused the U.S. of withdrawing intelligence-sharing to pressure Kyiv into halting attacks on Russian energy sites.
Ukraine also criticized a U.S.-Russia agreement to release 300,000 tonnes of diesel, calling it an investment in Russia’s war effort.
That deal was announced to lower fuel prices ahead of the U.S. midterm elections, following months of political pressure related to the Iran war and soaring fuel costs.
What to Watch Next
The inspector general’s findings will be critical in determining whether U.S. agencies played a role in the restrictions.
Ukraine’s continued use of Starlink will remain a key factor in its defence strategy.
Any future coordination between U.S. military and commercial satellite services may depend on transparency and trust.
