The radio that makes Russia's strike drones resistant to Ukrainian jamming is a Chinese-made part sold openly, and the company that makes it has escaped the sanctions hitting the rest of the drone supply chain, the OSINT group Frontelligence Insight found. The part, a mesh radio modem, has been pulled from downed Russian drones even as Western and Ukrainian sanctions expanded to cover the engines, navigation, motors, cameras, and chips around it.

Russia's war on Ukraine now runs on drones built largely from Chinese parts—a flow China keeps open to Moscow while restricting the same goods to Kyiv.

The part that isn't on any list

The modem is the XK-F358 mesh radio made by Shenzhen Xingkai Technology Co., Ltd. of Guangdong. It sells openly online. The company's Made-in-China storefront lists it at $8,100 to $9,000 apiece, and Serhii "Flash" Beskrestnov previously put the price near $7,000.

Ukraine and its partners have sanctioned Chinese suppliers of drone engines, navigation receivers, motors, cameras, and chips—one Ukrainian round aimed explicitly at parts for drones built to bypass electronic warfare—but not the radios.

Recovered from downed drones, and hard to jam

Ukraine's Defense Intelligence photographed an XK-F358 recovered from a downed Geran-5, and Beskrestnov photographed another taken from a Gerbera, Militarnyi reported on 19 January 2026.

The modem uses COFDM modulation and a mesh design in which each unit relays traffic for the rest, so packets reroute automatically when a node drops.

The same modem also turns up under a second name—HX-50, in a more industrial variant—and its use is no experiment: it spread onto Russia's Shahed-136/Geran-2 strike drones from July 2025 and reached serial integration by early September.

The network keeps working after losing roughly 80% of its nodes and can link drones across more than 100 kilometers, or up to 600 in relay chains, according to Beskrestnov, a Ukrainian defense adviser who has examined the recovered units. That is why conventional jamming struggles against it: an attacker has to suppress every node at once rather than break a single link.

What sanctions cover, and what they skip

Ukraine's National Security and Defense Council (NSDC) has sanctioned Chinese makers of navigation receivers, motors, cameras, and chips. The US Treasury designated Xiamen Limbach and Redlepus in October 2024, the EU added Shenzhen Minghuaxin in June 2026. No maker of radio or data-link modems appears among them.

None of the four sanctions regimes that have pursued Russia's Chinese drone suppliers—the US, EU, UK, and Ukraine—lists Shenzhen Xingkai, a direct check of each register by Euromaidan Press confirms.

The gap cuts both ways. Ukrainian battalion commanders and industry sources put the share of parts in a standard Ukrainian FPV drone—batteries, motor magnets, fiber-optic cable—at up to 65% Chinese-made, and Ukraine buys from Shenzhen too.

Cutting one supplier, then the next

Tatarigami, who founded Frontelligence Insight, argues the fix is to extend controls beyond individual firms to the entire chain—down to the optical fiber, the reels it ships on, and the machines that make it. Fiber-optic drones already make up about 60% of Russian FPVs in key sectors, Euromaidan Press reports. The record on firm-by-firm designation is discouraging: after Washington hit Xiamen Limbach, Beijing Xichao took over the engine shipments, Reuters found, and Kupol's Garpiya order climbed from 2,000 drones in 2024 to more than 6,000 this year. But among all component categories in a Geran drone, the one that enables jam-resistant control is the only one absent from the registers.

What controls can reach, and what they can't

Xingkai also markets the modem for civilian work—mining, firefighting, maritime. And as the Xichao case shows, cutting off one company rarely halts the flow.

China's foreign ministry claims it knew nothing of the parts exports, says it controls dual-use goods under its own law, and rejects sanctions it calls baseless.

The harder problem is that the same civilian electronics feeding Russia also stock Ukraine's drone lines, so any workable control has to reach named military buyers without severing the dual-use trade Kyiv still needs. And sanctions may not decide this contest at all: Ukraine is already testing electronic-warfare methods built to break the very mesh networks these radios create.

Ukraine has built an interceptor that catches Russian drones instead of ramming them. The company WINFLY has unveiled the WINFLY Spider, an interceptor equipped with a net-launcher to neutralize targets with a net and return to its launch point, the defense outlet Militarnyi reported.

The Spider is the newest entry in Ukraine's fast-growing interceptor-drone industry. Ukraine has fielded a widening range of cheap interceptors to counter Russia's massed drone attacks, and the Spider's distinction is reusability.

The netgun makes it reusable

Most interceptors are one-shot weapons that ram or explode against their target. The Spider instead carries the Karakurt net-launcher, made of high-strength aluminum and rated to work from −20°C to +50°C, which snares an enemy drone in a net while the interceptor itself stays intact and ready for repeat flights.

The economics are the point. The developers say each net shot about $27, while the drone remains undamaged. That turns the cost equation of drone defense, where an interceptor is often spent to down a single target, into one where the same aircraft can make many intercepts, paying only for a cheap net each time.

The platform and what it hunts

The Spider is built on an existing WINFLY interceptor. It uses the WINFLY 10 Hunter as its base platform, which operates at up to 5,000 meters, reaches 160 kilometers per hour, and has a range of over 18 kilometers.

It is designed for a range of Russian drones. The system targets fixed-wing UAVs, Mavic quadcopters, FPV drones, and fiber-optic drones, with flight times up to 25 minutes, deployment times of up to 3 minutes, and target detection ranges of up to 500 meters. The maker offers day and night versions.

One tool in a scaling defense

Ukraine is downing tens of thousands of Russian drones a month, per the Defense Ministry, and fielding interceptors from at least 29 licensed makers, with new designs like the high-altitude Tsyklop climbing above enemy drones and others ramming them.

Ukraine is shooting down drones at a fast-rising rate. Ukraine's Defense Forces destroyed 40,438 Russian fixed-wing drones, or "wings", in July 2026, Ukraine's Defense Ministry reported on 11 August.

The July figures mark a defense scaling up as fast as the threat it counters. Since the start of the year, Ukraine's Defense Forces have destroyed 195,000 Russian "wings" and 66,000 copters. A counter-drone effort is growing month by month against a Russian drone campaign that has itself expanded relentlessly.

The numbers climbed across drone types

Both categories of drone kills rose sharply. Fixed-wing "wings," the category that includes long-range attack drones like Shaheds, climbed from 27,711 in May to 40,438 in July, according to the ministry.

Copter kills rose even faster in proportion. The number of destroyed copters grew 42% in a single month, from 14,071 in June to 19,945 in July. The parallel rise in both types reflects a Russian drone offensive attacking on multiple fronts at once, from deep-strike Shaheds to short-range quadcopters over the trenches, and a Ukrainian defense expanding to meet each.

DELTA confirms every kill

Every strike has been confirmed by the DELTA system, and video recording of the shootdowns helps identify the most effective counter-drone tools for development and scaling, the Ukrainian Defense Ministry said.

That verification matters for a claimed tally. Rather than a bare count, the numbers are tied to Ukraine's battle-management system, which logs and video-confirms each kill, the same DELTA platform whose combat data now trains Ukraine's target-detection AI.

The count is one side of the drone war

The figures capture only Ukraine's defensive half of a war fought increasingly by drones. Russia has expanded its drone production and nightly launches throughout 2026, aiming to overwhelm Ukrainian defenses with mass, and the rising Ukrainian kill counts are the answer to that escalation, not a sign it has eased.

Ukraine is testing a new electronic-warfare solution to protect heavy bomber drones and unmanned ground vehicles (UGVs) from cheaper FPV drones. The project has reached field testing, with several prototypes sent to military units, RBC-Ukraine reports.

Ukraine's war has become a laboratory for the economics of unmanned combat, where a mass-produced quadcopter can take down platforms that cost dozens of times more, forcing both volunteer foundations and defense firms to look for asymmetric answers on the electronic side of the front.

$20,000 bomber vs. $300 drone

The gap runs more than 60-to-1. Liuba Shypovych, head of the Dignitas foundation, told RBC-Ukraine that a heavy bomber can cost around $20,000, while an FPV drone capable of damaging or destroying it can cost about $300. Shypovych said the bombers are particularly vulnerable because they are relatively slow and less maneuverable than smaller FPVs, and that shootdowns are becoming increasingly frequent.

Yet Ukraine cannot simply stop using the larger drones. According to Shypovych, they are used to deliver water, food, and ammunition to positions that are difficult or impossible to reach by ground. The military therefore approached Dignitas with a request to protect the platforms, and the team is working on the task together with the company Aura.

The jammer has a problem of its own

Equipping a heavy bomber with electronic warfare creates an unusual technical problem. The bomber needs a communications link with its operator, but the same EW system designed to disrupt an incoming enemy FPV could also interfere with that control channel. The problem extends to UGVs, including platforms used to evacuate wounded soldiers. Shypovych said the goal is to develop EW that can counter hostile drones without cutting the Ukrainian platform's own communications.

From the test range to the first units

Dignitas and Aura are testing the systems at training grounds and have already sent several samples to military units. Shypovych expects the solution to be ready in roughly two months.

The effort comes as Ukraine rapidly expands its use of unmanned ground systems. Kyiv has set a target to contract at least 50,000 UGVs, with robots already taking on logistics and evacuation tasks in high-risk zones. Ukrainian forces have already received 1,028 UGVs through the DOT-Chain Defense marketplace, with the systems handling logistics, evacuation, mine-laying, and combat. Ukrainian Vampire bombers have also been upgraded to shrug off Russian jamming and even hunt the jammers themselves.

Fedir's four and a half years compress a shift the Ukrainian military has been living through since the invasion. Ukraine's forces have moved from Soviet-era systems, through Western precision weapons, to a homegrown drone war that now shapes the front line more than any single piece of hardware. Soldiers have had to relearn their job every year, mastering whatever technology arrives next, because the side that adapts faster survives. Fedir's story shows how fast that reinvention has come, and what it costs the people carrying it out.

"We give battle, boys — this is war," battalion commander Mykhailo Myronenko told the men. Fedir, a former construction worker, was on combat duty with a Lviv air defense brigade, and his job was diesel: keeping the generators running so the S-300 launchers never lost power. On the busiest days, he says, the unit fired eight to ten times.

In 2024, the war upgraded around him. He retrained on the IRIS-T SLS, a German air defense system, and moved from generators to the launch itself. "Three missiles. Three targets down," he says of his first launches on Western hardware.

"I was standing in snow mixed with mud, and I understood I was really useful to my Ukraine," said Fedir.

Then he left. The IRIS-T sits well back from the front, and Fedir gave it up to fly drones, because he wanted to see the results of his work up close, through his own camera rather than on someone else's screen. He flew his first missions in Sumy Oblast, moving onto position in the dark with the headlights off. Through the camera, he saw his first Russian soldier walking a trench.

Drone operators are the eyes of the front, and among the most hunted people on it for exactly that reason. The task that matters most, he says, comes after the flight: not bringing a "tail" home, not letting an enemy drone track the path back to your shelter. One day, he says, it went wrong. A Russian FPV drone found their group, a comrade made cover shouting "FPV," and the blast was followed by artillery meant to finish them off. Fedir took a serious concussion, spent a few days in a hospital, and went back. "I was desperate to return. Because this is my war," he said.

The callsign came by chance, from the work. When the jamming is heaviest, and he is fighting to hold the link to his drone against Russian electronic warfare, he starts to move at the controls, a small involuntary dance. His comrades named him Dancer.

His rotation has ended, and he could go back to the IRIS-T. He has chosen to stay on the zero line. After the war, he says, he wants the ordinary things: a family, and the peace to build again.
