Ukrainian defense-tech firm BlueBird Tech has begun renting out its Hrets electronic-warfare jammers by the day, in what it calls Ukraine's first such service, the company said on 29 September 2026. Electronic-warfare gear—the devices that scramble the radio links attack drones rely on—is normally bought outright, renting lets a user take a system for a single mission or test it before committing.

The pull is a war where cheap first-person-view (FPV) drones have made portable jamming a routine need, one many users face only for a stint.

How renting works

After paperwork and a deposit equal to the device's full price, the system is handed over, and that handover counts as day one. Each day's rent is then drawn from the deposit, return the system working and undamaged and the renter gets back what is left. Keep it long enough that the fees add up to the full price, and the jammer passes to the renter automatically. Renting is open to individuals, companies, charities, and volunteer groups.

Three models, and what each one jams

The Hrets XL is a modular FPV jammer built from two to 10 working modules, priced case by case. The vehicle-mounted Hrets 4MC is an anti-drop system that jams DJI Mavic-type quadcopters—the drones Russian forces use to drop munitions—for about $56 a day. The lightweight Hrets 4M jams FPV drones at a stated 70 to 400 meters for about $67 a day. One Ukrainian firm has even packed detection, decoding, and jamming of an FPV signal into a single device.

Ukraine likely neutralized Russia's drone defenses north of Lyman before sending armor into the third phase of its Vivaldi counteroffensive, the Institute for the Study of War (ISW) assessed. An intermediate-range strike campaign against Russian logistics and electronic warfare paved the way, the think tank said.

Drones have made this front so deadly that armor now mostly fights from kilometers back. That is what makes Ukraine's armored push onto fortified positions near Lyman stand out. Russia has already shifted its effort south toward Sloviansk after losing the Lyman pincer.

Armor reached Russian bunkers without drawing drone strikes

To break the strongest Russian fortifications, Ukraine used old Soviet BTR-60 armored personnel carriers rebuilt as remote-controlled explosive vehicles, the 3rd Army Corps says.

Ukrainian forces drove them up to heavy Russian fortifications without coming under Russian drone strikes, ISW noted. The think tank said this indicates Ukraine neutralized or otherwise negated Russia's drone defenses in the area.

Strikes on fuel starved Russia's jammers

Ukraine achieved tactical drone overmatch through extensive shaping operations and an intermediate-range strike campaign, ISW said. Those strikes targeted the Russian drones and electronic warfare (EW) systems that would otherwise have hunted the advancing vehicles.

The 3rd Army Corps reported on 17 September that strikes on Russian logistics in occupied Luhansk Oblast had degraded Russian fuel supplies to the front, ISW wrote that day. The corps said that strained Russia's ability to use drones and EW against Ukrainian drones. EW systems consume a lot of power, and Russian troops run them on diesel generators, ISW explained.

Deputy corps commander Maksym Zhorin credited strict information silence and a "Protective Drone" system of EW assets, according to the same assessment. He said it helped neutralize around 20,000 Russian drones. The corps had earlier described mapping Russian command posts and striking them to sow panic.

Five settlements and 2,000 Russian losses

The corps liberated Nove, Ridkodub, and Katerynivka and restored control over Karpivka and Novomykhailivka, it said on 28 September. The phase added 51 km², bringing the total since the offensive began to 176 km².

Russian losses reached 2,000 personnel, and more than 250 Russians were taken prisoner, according to the corps. Corps commander Andrii Biletskyi said a feint from Shandryholove toward Zelena Dolyna drew Russian reserves away from the real target, Nove.

The first two phases had reportedly cleared more than 125 km² north of Lyman.
