Looking back, it was a prescient warning. Just the day before the Kremlin sent 19 unmanned aerial vehicles deep into Polish territory, prompting NATO to scramble its most advanced fighter jets and anti-missile air defenses, I met with the commander of a Ukrainian air defense unit protecting the city of Sloviansk from Russian drones. We sat outdoors in a quiet courtyard near the city center, just 15 miles from the front line. The officer, who goes by the name Fin—he worked in the financial sector, running a grain export company, before volunteering for combat duty in 2022—explained how his team of advanced IT technicians and other specialists uses signals intelligence (SIGINT) to intercept incoming Russian drones.
A tall, well-built man with a graying beard, Fin took out his phone to show me a video of a typical intercept. The unit had hacked into the frequencies the targeted Russian drone was using to send video images back to its pilot behind the front line, letting us see the battlefield through enemy eyes. Ukrainian forests and fields floated by, bracketed by the drone’s spinning rotors on the edges of the frame. Then it all went gray. The SIGINT unit, code-named Specter, had used the device’s own navigational signals to bring it down, crashing to earth far short of its target.
“We do this for a fraction of what it would cost Europe and the U.S.,” Fin explained. “No jets, no million-dollar weaponry. And we intercept a large number of drones.” Just the night before, he told me, a routine evening in Sloviansk, the unit brought down 198 enemy UAVs. “Europe and the U.S. should start learning from us before it’s too late,” he warned. “They’ll either learn from our experience, or they’ll learn on their own—the hard way.”
