For more than two years, Ukraine's mid-range strike-drone campaign has leaned on a piece of infrastructure Moscow cannot touch directly: Elon Musk's Starlink satellite constellation. Drones that fly deep behind the front line stay connected to their operators via Starlink terminals, letting crews retarget, correct course, and confirm strikes in near-real time even when local radio links are jammed or the aircraft is well beyond line of sight. Russia has spent years trying to find a way to sever that link. According to a Reuters report published July 8, it may finally have fielded a system built specifically for the job — and Ukraine is already blowing it up.

The system is called Volna Kupol Garant. It is built by Rossiysky Kupol, a manufacturer based in occupied Crimea, and it is now being deployed at scale. Ukrainian officials say Russian forces have moved roughly ten of the units into the field.

What the jammer actually does

Volna Kupol Garant is not a battlefield radio jammer in the conventional counter-UAS sense — it doesn't chase individual drone control frequencies. Instead, it targets the Ku-band uplink that Starlink terminals use to talk to satellites, operating across the 14–14.5 GHz band, which Militarnyi's reporting corroborates; Defense Express additionally reports the band is split into eight channels of 62.5 MHz each. The hardware is spread across six trailers housing satellite dishes under radio-transparent domes, giving the system a distinctive silhouette that Ukrainian reconnaissance has learned to recognize.

Serhii Beskrestnov, an adviser to Ukraine's Defense Ministry who tracks Russian electronic-warfare deployments closely, described the basic method to Reuters: the system uses a set of dishes to blast a signal strong enough to "destabilise the Starlink connection" over a given area. Militarnyi and Defense Express both put that coverage footprint at roughly 20 square kilometers — about 7.7 square miles, per Reuters' conversion — centered on wherever the trailers are parked.

That number is the crux of the problem, both for Russia's ambitions and for anyone trying to judge how much of a threat the system really poses.

Why one satellite at a time isn't enough

Starlink is not a single relay point sitting in geostationary orbit that a jammer can simply point at and disable. It is a mega-constellation of more than 10,000 active satellites in low Earth orbit, each covering an area with a radius of roughly 1,000 kilometers, with new satellites continuously replacing the ones overhead every few minutes, according to Defense Express's analysis. Volna Kupol Garant, per that same reporting, can only jam one Starlink satellite at a time. The moment the constellation hands a terminal off to the next satellite in view — which happens on a cycle of just a few minutes — the jammer has to reacquire and retarget, and the terminal on the ground may simply reconnect through a satellite the jammer isn't touching.

That architecture is precisely why Starlink has proven so resistant to conventional jamming throughout the war: there is no single point of failure to attack, only a rotating cast of thousands of targets, each visible for a short window. A $1.5 million ground system is trying to plug a hole in a net with holes numbering in the thousands.

Rob Lee, a senior fellow at the Foreign Policy Research Institute, told Reuters the systems are nonetheless worth watching if Russia manages to scale production: "If they scale production of the jammers, they could make it more difficult to conduct the middle-strike campaign." The implication is not that any single unit is decisive, but that enough of them, distributed across enough sectors of the front, could impose a persistent tax on Ukrainian drone operations even without ever fully severing the link.

This is not Russia's first attempt to blunt Starlink's role in the war. In April 2022, C4ISRNET reported that SpaceX shut down an earlier Russian electromagnetic-warfare attack on Starlink within about a day of it surfacing, patching the vulnerability with a software update — a turnaround Pentagon electronic-warfare officials said they wanted the military to emulate. Volna Kupol Garant, more than four years later, is a far more deliberate and purpose-built answer to that same problem, but it still runs into the constellation's fundamental design advantage: there is no single link to patch or point to jam.

Ukraine is hunting the jammers directly

Rather than trying to out-engineer the jamming signal, Ukraine's response has been more direct: find the trailers and destroy them. Reuters reports that Ukraine's 422nd Unmanned Systems Regiment has already struck and destroyed at least two of the roughly ten Volna Kupol Garant installations identified so far, using strike drones cued onto the system's own emissions. Militarnyi reported that Ukrainian forces have published footage of one installation's trailers being struck by strike drones, with reconnaissance drones providing support.

The crew commander of one strike drone unit, identified by the call sign "Dyryhent," gave Reuters a blunt after-action assessment: "As soon as we struck that installation, our Starlink-equipped drones flew without problems." In other words, the jammer's own 20-square-kilometer footprint — the very thing that makes it powerful enough to disrupt a satellite link — also makes it a fixed, locatable, and comparatively soft target once its signature is identified. A system built around six trailers cannot hide the way a dispersed network of infantry radios can.

Russian forces are not relying solely on RF jamming to counter the mid-range strike-drone threat, either. Reuters notes that camouflage — including disguising fuel convoys, such as painting fuel tankers to resemble civilian water or milk trucks, to make them harder to identify and target — remains a complementary countermeasure, suggesting Moscow views electronic warfare as one layer in a broader defensive approach rather than a silver bullet.

The economics of the fight

At roughly $1.5 million per unit, Volna Kupol Garant sits in an awkward spot on the cost curve. It is far more expensive than the FPV strike drones that can find and destroy it, but its effectiveness is capped by physics: one satellite link jammed at a time, against a constellation designed to route around exactly that kind of localized interference. Every unit Russia loses to a strike drone erases a seven-figure investment in a matter of seconds, while the strike drones themselves cost a small fraction of that. For now, the exchange rate appears to favor Ukraine — though that calculus could shift if Russia manages to mass-produce cheaper variants or disperses the systems widely enough that finding all of them becomes impractical.

Why It Matters

Starlink connectivity has become one of the load-bearing pillars of Ukraine's deep-strike drone campaign, and this is the clearest evidence yet that Russia has built a dedicated, purpose-made system to attack that specific dependency rather than relying on generic EW jamming. That matters for two reasons. First, it confirms Starlink's role as a contested piece of military infrastructure that adversaries are willing to spend millions of dollars per unit to disrupt — a dynamic with implications far beyond this war, for any force that leans on commercial low-Earth-orbit connectivity for drone operations. Second, the specific failure mode here — a jammer powerful enough to matter but geographically fixed enough to be hunted down — is a preview of a broader pattern in counter-UAS and counter-connectivity warfare: systems capable enough to disrupt a hardened target often can't stay hidden while doing it. How that trade-off resolves, at scale, may say as much about the future of drone warfare as any single munition.
