The Invisible Russia-Ukraine Battlefield | WIRED

Russia’s systems were “not very mobile, not very distributed,” Clark tells WIRED. Their relatively small number of big systems, Clark says, “weren’t really relevant in the fight.”

Moscow’s strategy assumed there would be a relatively static battlespace. Along the front, they would deploy the Infauna, a heavily armored vehicle that targets radio communications. Further out, around 15 miles from the front lines, they would send the Leer-3, a six-wheeled truck capable of not only jamming cellular networks but of intercepting communications and even relaying SMS to nearby cell phones. Even further out, from a range of about 180 miles, the fire-truck-sized Krasukha-4 would scramble aerial sensors.

“When you get close to the front, you get electronic weather,” Clark says. “Your GPS won’t work, your cell phone won’t work, your Starlink won’t work.”

This electromagnetic no-man’s-land is what happens when you “barrage,” Clark explains. But there’s a big trade-off, he says. Jamming across the spectrum requires more power, as does jamming in a wider geographic area. The more power a system has, the bigger it must be. So you can disrupt all communications in a targeted area, or some communications further afield—but not necessarily both.

Move Fast and Jam Things

Russia’s military was marred, early in the war, by bad communication, worse planning, and a general sluggishness in adapting. Even still, it had a big head start. “Unfortunately, the enemy has a numerical and material advantage,” a representative for UP Innovations, a Ukrainian defense tech startup, tells WIRED in a written statement.

So Ukraine developed two complementary strategies: produce a large volume of cheaper EW solutions, and make them iterative and adaptable.

Ukraine’s Bukovel-AD anti-drone system, for example, fits comfortably on the back of a pickup truck. The Eter system, the size of a suitcase, can detect the jamming signals from Russian EW systems—allowing Ukraine to target them with artillery. Ukrainian electronic warfare company Kvertus now manufactures 15 different anti-drone systems—from drone-jamming backpacks to stationary devices that can be installed on radio towers to ward off incoming UAVs.

When the full-scale war began in 2022, Kvertus had one product: a shoulder-mounted anti-drone gun, like the EDM4S. “In 2022, [we were producing] tens of devices,” Yaroslav Filimonov, Kvertus’ CEO told me when we sat down in his Kyiv offices this March. “In 2023 it was hundreds. Now? It’s thousands.”
