A Ukrainian Hornet drone struck a Russian radar system about 120 kilometers behind the front, Taras Myshak, senior communications officer of the 59th Separate Assault Brigade of Unmanned Systems, said on Suspilne on 28 September, ArmyInform reported. The brigade's Signum unmanned systems battalion carried out the strike about a week earlier, he added.

Russia's air defenses depend on radars to see Ukrainian drones and missiles coming. Every radar it loses weakens that watch and gives the next Ukrainian strike a better chance of getting through.

According to Myshak, the target was a "quite expensive" Russian radar system.

A radar system is effectively the "eyes" of the Russian air defense system: it detects aerial targets, determines their coordinates, and transmits information to other elements of the system.

Russians continue probing Ukrainian defenses

Russian forces in the brigade's zone, roughly along the Donetsk Oblast border, continue to operate in small infantry groups and use infiltration tactics, Myshak says. At the same time, the Russians are trying to cut Ukrainian logistics, he adds, saying that the brigade is effectively holding the Russian army back from infiltrating into Dnipropetrovsk Oblast.

The Russians' main means in this sector remain drones and infantry, the serviceman says. The number of infantry has decreased somewhat compared with previous periods, but the pressure from the enemy has not stopped, he adds.

"Of course, they will try, they will constantly probe, so to speak, our defense with their infiltrations. And likewise with drones, of various ranges, working on logistics, making it impossible for us to enter positions, to deliver everything necessary to the positions, in order to make our defense impossible," Myshak emphasized.

At the same time, Ukrainian troops are trying not only to defend against these actions but also to deprive the Russians of radars, electronic warfare systems, and other equipment, the serviceman says. "We likewise don't let them relax," he said.

Ukraine systematically knocks out the "eyes" of Russian air defense

In October 2024, Ukraine's military said it had hit a Russian Nebo-M radar station with ATACMS ballistic missiles to blunt Moscow's ability to spot and shoot down aircraft and missiles, Reuters reported. The military estimated each such system at more than $100 million.

Ukraine is systematically increasing its use of medium-range strike drones, which can hit targets up to 200 kilometers deep inside enemy territory, the Ukrainian Defense Ministry reported in May this year. Russian air defenses and radars are among the main priorities of such operations, as their destruction weakens the system for detecting and intercepting aerial targets, the ministry said. Medium-class drones, including the FP-2, Hornet, and Bulava, play a critical role in such strikes, the ministry noted.

According to the General Staff of the Armed Forces of Ukraine, Ukrainian forces struck at least 25 major Russian air defense and radar systems during April, about 12 of which were radar systems, the Ukrainian Defense Ministry also wrote in May this year.

A Ukrainian jamming-systems maker went to a US Army base to do to candidate drones what Russia does to Ukraine's: flood them with electronic warfare (EW) and see which survives. Unwave company has tested four of its EW systems at Fort Carson in Colorado as part of the Pentagon's Drone Dominance program and has been asked to continue supporting it.

The Pentagon is using Drone Dominance to choose the drones it will buy at scale, more than 200,000 by 2027, and it needs to know they work under jamming, the condition that decides most drone fights in Ukraine.

So it brought in a Ukrainian electronic-warfare maker to supply that jamming, turning Ukraine's hard-won counter-drone experience into the test bench for American hardware. It follows a pattern in which US defense efforts adopt Ukrainian battlefield models.

Ukraine brings the jamming

From 24 August to 2 September, Unwave's team worked at the base, running scenarios that pitted its jammers against drones tasked with protecting fixed positions, moving vehicles, and infrastructure.

The crews operated from three separate positionsat short and long range to compare how drones from different manufacturers held up.

"Our mission was to create conditions as close to the real battlefield as possible," the company said, adding that it judged the tasks successfully completed but could not detail the scenarios for security reasons.

In all, 14 drone makers and three electronic-warfare firms took part.

Four systems on show

Unwave brought four:

• VIHA, which it calls Ukraine's first tactical-operational jammer for directed suppression of drones
• BOOMBOX, built to shield troops and positions from FPV and drop-drones
• SHATRO, for vehicles
• CHOVEN-2, a multi-frequency amplifier for cars.

Its participation was organized by Revenant Technologies, a US firm that specializes in bringing combat-proven defense tech to the American market, and helped design the scenarios using its ties to Ukraine and frontline experience.

A foothold in the US market

For Unwave, the value is a door into the alliance's security architecture. The event showed the importance of Ukrainian, American, and European specialists testing together, the company said, and "such interaction will help integrate Ukrainian technologies into the security architecture of our allies."
