Ukraine's Security and Defense Forces have "put out of action" more than 51% of Russia's oil refining capacity through recent long-range strikes, Defense Minister Yevhenii Khmara said in a statement published by the Defense Ministry on 4 October. These "carefully thought-out" actions were aimed at "bleeding the Russian war machine" and "destroying its military-economic potential," Khmara said.

Ukraine treats Russia's refineries as a priority target because their revenue helps fund the war. Even Russian President Vladimir Putin claimed on 1 October that the strikes had cost Russia 1% of its GDP and had "partially" achieved their goal, Interfax reported.

The ministry did not publish how it calculated the figure.

"The consequences of Ukrainian operations are not always visible immediately. But the effect accumulates and produces a tangible result," the ministry said.

Ukrainian deep strikes continue to bring the war to Russian territory

The ministry named eight recently struck facilities, among others. One of them is the Moscow Oil Refinery, which Ukraine targeted in a massive drone attack on the night of 20 September, Ukrainian President Volodymyr Zelenskyy said. The refinery, operated by Gazprom Neft in Moscow's Kapotnya district, supplies about 40% of Moscow's fuel market and 70% of the Moscow region's demand for gasoline and aviation fuel, according to Russian news Telegram channel Astra.

Another was KINEF, which Ukraine has attacked repeatedly. It is Russia's second-largest oil refinery by capacity, and the Ukrainian military struck it on the night of 30 August, setting off a fire at the facility.

The ministry also named the Yaroslavl, Perm, Ilsky, Saratov, and Syzran refineries and the Ust-Luga port complex.

Ukraine triples production and procurement of long-range drones—and this is not the end

This year, Ukraine has tripled the production and procurement of long-range attack drones, the ministry said.

"This is not the limit. We will continue to scale up deep-strike capabilities," the statement said.

International cooperation is part of that push. Berlin will fund the production of additional DeepStrike-class long-range drones in Ukraine, German Defense Minister Boris Pistorius said after a meeting of the Ukraine Defense Contact Group on 15 April. The sides also agreed to jointly develop and produce a medium- and long-range drone system.

Ukraine and Germany also signed an agreement on the joint production of Bars drones, Ukrainian Foreign Minister Andrii Sybiha said on 8 July. The Bars' modular design allows it to be used for deep strikes, among other missions.

Oil refinery output has fallen

Russian refineries cut crude oil processing by 14% in the first nine months of the year compared with the same period last year amid Ukrainian drone attacks, according to calculations by two industry sources.

Experts' estimates of the decline differ widely. In August, Serhii Vakulenko of the Carnegie Russia Eurasia Center put it at 25–28%, while Russian economic commentator Vyacheslav Shiryaev put it at 65–70%, according to Defense-Aerospace.

Fuel production data give a more concrete picture: in July, Russia's gasoline and diesel output was about a quarter to a third lower than in March 2026, the outlet reported.

Russia is wiring its long-range attack drones together by a mesh network in flight and buying pricier, higher-resolution cameras for them, Ukraine's Air Force reported on 29 September. Its spokesperson said one drone could serve as a scout, strike drone, and relay for the rest, which is why they often fly one behind another over long distances. Chains of them keep crossing near the Belarus border, UkrInform reports.

For Ukraine, the danger in each such upgrade is arithmetic: the more Russia networks cheap, once-disposable drones and pushes its control links away from the front, the harder they become to jam or shoot down, and the more of them reach the cities they are aimed at.

Sharper, pricier eyes

Ihnat said on a national broadcast that Russia is sourcing higher-quality materials and raising the resolution of its drone cameras. The cameras it buys are increasingly expensive and higher-quality, he said, which lets its operators study the ground in fine detail and use each drone for a specific purpose.

On a mesh network, he said, the drones talk to each other and hand the control signal back toward the operator, so no single link has to carry it alone.

Chains along the Belarus border

Asked about relays operating out of Belarus and about Russia's guidance of jet-powered Shaheds, the exploding drones it fires in swarms, Ihnat said Moscow had already claimed its satellite network was ready. He confirmed mesh networks are in use and said their use was quite dangerous. Ukraine has no information yet on whether Russia is using towers, he said.

It often sees drones crossing long distances in chains along the Ukrainian-Belarusian border, so nothing can be ruled out, but intelligence would have to confirm whether such relays exist. Asked whether Russia is preparing a fresh ballistic strike, he said intelligence would warn when extra vigilance is needed.

Ukraine's countermeasures

Ihnat has also said Russia launched more attack drones in September than in August, counting 3,177 jet-powered drones so far this month against 2,850 in August. To knock them down, Ukraine leans mainly on tactical aviation, including F-16 fighters, and on ground-based air defense when missiles are available, he said, with shoulder-fired man-portable air-defense systems (MANPADS) working well against jet drones inside their range. He said Ukraine needs more missiles for both Patriot systems and ground-based launchers, plus faster domestic solutions it can scale up.

Ukrainian company Vyriy Industries is bringing a new tactical reconnaissance drone, Slavic, to the market, Oboronka reports, citing information from the manufacturer. The control system of the new drone will be familiar to DJI Mavic operators, the company also said.

Mavic has long been one of the main reconnaissance tools used by Ukrainian forces, with Ukraine relying heavily on supplies of these drones from abroad. After Ukrainian President Volodymyr Zelenskyy said China had stopped selling drones to Ukraine, the country began seeking alternatives. Slavic is one of these domestic alternatives, designed not only to replace Mavic but also to adapt its capabilities to current battlefield conditions, allowing reconnaissance crews to operate farther from the line of contact and reducing risks to personnel.

Slavic has a tactical range of up to 30 kilometers without GPS

Slavic can remain airborne for up to 1.5 hours because it is equipped with a 40,000 mAh solid-state battery, the media outlet notes. The drone has a tactical range of up to 30 kilometers, the report says.

The aircraft can operate without GPS, as Slavic uses optical positioning for navigation. The pilot can also select a less congested channel and operate more effectively in difficult terrain because the communications system operates across a wide range of channels.

The manufacturer notes that for surveillance, Slavic is equipped with a daytime 2K digital camera mounted on a three-axis stabilized gimbal, with 10x optical and 30x hybrid zoom.

The system is supplied as a ready-to-use package “out of the box,” with all the equipment needed for operation without additional field modifications.

The drone is designed to keep crews farther from the front line

The company said its new drone has successfully completed initial combat trials with seven units of the Ukrainian Defense Forces and is preparing for scale-up, the media outlet notes.

“The war has changed, and so have the working conditions for crews. The kill zone has expanded, while available commercial drones have a limited tactical range. The main task now is to provide the military with a specialized platform that can fly longer and farther, so crews can operate farther from the line of contact. This is exactly why we began developing Slavic,” said Oleksii Babenko, founder and CEO of Vyriy Industries.

At the same time, the team is working on new Slavic configurations, including testing thermal imaging modules for nighttime reconnaissance. The manufacturer is also preparing the platform for scaled-up production and deliveries to the Ukrainian Defense Forces, the company told the media.

“Frankensteins” and Ukrainian-made drones are among the options for replacing scarce Mavics

The Ukrainian military had widely used Chinese DJI Mavic 3 drones, including to adjust artillery fire, monitor infantry positions and conduct surveillance, prompting Ukraine to seek ways to replace the shortage. More than five alternatives to the Chinese drone had already been developed in Ukraine, the Ministry of Strategic Industries of Ukraine confirmed to RBC-Ukraine in July 2025.

There are also other options for replacing them. The main work in military units is being done with “Frankensteins,” drones assembled from two or three damaged aircraft, Mavic UAV pilot instructor “Dobryi” said in an interview with Militarnyi in July this year. At the same time, such drones are less reliable than new ones, he added.

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.

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.
