The Ukrainian military can again use SpaceX’s Starshield satellite service on the move, a Defense Ministry source told Recorded Future News on Thursday, days after sudden restrictions disrupted drone missions along the front line.

Starshield, a military-grade version of SpaceX’s Starlink internet service, keeps Ukrainian units connected through terminals mounted on vehicles and drones as they travel.

Overnight Tuesday, without warning, that connection was disrupted as new restrictions limited how fast a terminal could move and still hold a connection — forcing troops to cancel combat missions and complicating drone operations, logistics and reconnaissance.

“Starshield connectivity while in motion has now been restored and remains operational,” the source said, citing reports from military units and speaking anonymously because they were not authorized to speak publicly.

The ministry told Recorded Future News on Wednesday that connections had improved at speeds of up to 160 kilometers per hour (about 100 mph), though the formal speed limit remained in place.

The cause of the restrictions remains unclear. Officials are in talks with SpaceX and its partners to find out, the source said.

Musk points to Washington

Responding Wednesday to former Ukrainian Defense Minister Mykhailo Fedorov, who called for the speed limits to be lifted entirely, Musk said the U.S. government controlled Starshield and was responsible for deciding how the service could be used.
