Pentagon Impressed by Starlink's Fast Signal-Jamming Workaround in Ukraine

SpaceX's Starlink satellite internet service is attracting some attention from the Pentagon for its ability to quickly foil signal-jamming attacks that likely came from Russia. 

"In kind of the way Starlink was able to upgrade when a threat showed up, we need to be able to have that agility," Dave Tremper, director of electronic warfare at the Office of the Secretary of Defense, said during the C4ISRNET military conference on Wednesday.

Few details have emerged about the signal-jamming attack Tremper referred to, or how it was stopped. But on March 4, SpaceX CEO Elon Musk tweeted about the incident, which affected Starlink dishes in Ukraine. Later, he added: "Some Starlink terminals near conflict areas were being jammed for several hours at a time. Our latest software update bypasses the jamming. Am curious to see what’s next." Three weeks later, he added: "Starlink, at least so far, has resisted all hacking and jamming attempts."

Tremper brought up the incident when he was asked during the C4ISRNET conference whether the war in Ukraine is highlighting any "gaps" in the US’s electronic warfare capabilities. 

"It was eye-watering to see the news report that the Russians were trying to jam Starlink, and that almost the next day—I think it was in fact the next day—Starlink had slung a line of code and had fixed it. And suddenly that was not effective anymore," Tremper said. 

He was especially impressed with how quickly Starlink was able to adapt and stop the signal jamming. In contrast, the US military would have needed to go through several steps, involving a "significant timeline" if it faced a similar jamming incident to its equipment.

"There’s a really interesting case study to look at the agility that Starlink had in
