Musk says US government may be behind slowdown of Ukraine drone speeds

Elon Musk has suggested that the US government may be behind restrictions on the speed at which some of Ukraine's weapons can travel and stay connected to SpaceX's Starlink internet network.

Starlink is a vital tool allowing Kyiv to guide drones to Russian targets and also protect its own skies, but on Tuesday night Ukraine said unexpected new speed limits were disrupting its battlefield missions.

An adviser to President Volodymyr Zelensky said he believed the restrictions were not a coincidence and were related to the latest strains between Kyiv and Washington.

Musk said that Starshield, the military-grade sister service to Starlink, is controlled by the US government, and "any limits on speed or usage are decided by the US military and ultimately [the US president]".

Musk - writing on X - had been responding to pleas from Ukrainian officials to restore connectivity, including from Zelensky who told UK media: "I hope that it's a mistake, maybe [a] huge technical problem. I don't know, but we are asking to... switch [it] on."

Starlink, which is owned by Musk's SpaceX, restricted speed limits on Tuesday night to 100mph (160km/h), meaning any weapons that travelled faster than that lost connectivity to the network.

It had been partially restored by Wednesday evening, Ukraine's former defence minister Mykhailo Fedorov said.

"Removing Starshield's speed limit entirely is now critical for Ukraine's defense," he wrote on X, thanking Elon Musk and asking for his "continued support".

About an hour later, Musk replied to that post, defending his company's involvement.

"Starshield systems are owned and controlled by the US government. Any limits on speed or usage are decided by the US military and ultimately POTUS," he wrote.

Musk added that Starlink is for "civilian or defensive activities and cannot be used for offensive military action, as doing so would be inappropriate for a commercial company".

The US government has not commented.

While both companies are owned by Musk's SpaceX, Starlink is a civilian service that uses satellites in low Earth orbit to provide internet access, particularly in remote areas, while Starshield is designed for government and military use.

The restrictions on Tuesday night came as Russia launched deadly attacks against Ukraine that killed several people in Kyiv, officials said, and hit communications and energy facilities used by Ukraine's military.

Zelensky said it was "one of the largest attacks" from Russia, and while "a significant part of the drones were shot down" there were "also hits".

At least 600,000 people across Ukraine were left without electricity, and residents said they received no warning of incoming drones before they hit.

"It is clear that this action cannot be a coincidence and is related to the current political situation," Zelensky's adviser Serhiy Beskrestnov wrote on Telegram on Wednesday morning.
