Ukraine's War on Russia's Refineries: A Target-by-Target Account of May 2026.
May 2026 was the worst month on record for Russia's oil-refining industry. By the time it ended, roughly a quarter of the country's total refining capacity sat idle, and according to Reuters reporting cited by the Institute for the Study of War, virtually every major refinery in central Russia had halted or scaled back fuel output. Ukraine's Unmanned Systems Forces commander, Major Robert "Madiar" Brovdi, counted ten major refining and transshipment facilities hit by his branch alone in the first twenty days of the month - six of them forced offline - and that count excluded strikes carried out by other Ukrainian units. What follows is a facility-by-facility account of where Ukraine struck, what those plants were worth, what was destroyed, and why each one mattered.
1. Kirishi Refinery - Leningrad OblastCapacity: 20 million tons/year (Russia's second-largest refinery)
Struck: night of May 4–5
Kirishi opened the month and set its tone. Ukrainian forces hit the plant on the night of May 4–5, and by Reuters' account it had fully halted operations from May 5 onward. With a processing capacity of 20 million metric tons per year, Kirishi is one of the two largest refineries in the entire country, which made its shutdown the single most significant capacity loss of the month. Its location in the far north - well away from the front - also underlined how little of Russia's interior remains beyond Ukraine's reach. Knocking out a plant of this size in the first week meant that everything Russia lost afterward stacked on top of an already enormous hole in national refining output.
2. Ryazan Refinery - RyazanCapacity: ~17 million tons/year (Rosneft)
Struck: May 15
Casualties: at least 4 killed, dozens wounded.
The Ryazan strike was the deadliest event of the campaign. Drones hit two apartment buildings alongside the refinery and industrial site, killing at least four people and wounding dozens, including children, according to regional governor Pavel Malkov. The attack came a day after a Russian missile and drone strike on Kyiv killed at least 24, and was widely read as direct retaliation, with President Zelensky having ordered his military to plan a response. The damage was severe: satellite analysis published by Dnipro OSINT and reported by Militarnyi showed 90–100% of the refinery's processing capacity disabled, with multiple hits on the AVT-4 and AVT-3 primary crude distillation units, three destroyed product storage tanks, and prior damage to the ELOU-AVT-3, ELOU-AVT-6, and AVT-1 units. Ryazan is one of Russia's largest fuel plants and the main motor-fuel supplier for the regions around Moscow, producing every grade of gasoline, diesel, aviation kerosene, fuel oil, bitumen, and petrochemical feedstock. Russia's Defense Ministry claimed it intercepted 355 Ukrainian drones countrywide on the night of the strike - a nationwide figure, unverified, and not specific to Ryazan.
3. Moscow Refinery - MoscowCapacity: not publicly specified (Gazprom Neft)
Struck: mid-May (suspended ~May 17)
The Moscow refinery suspended operations around May 17 following drone strikes, according to Reuters. Sitting in the capital region, it is one of the country's most politically sensitive industrial sites, and its repeated suspension throughout the year carried a symbolic weight beyond its raw output: if the refinery serving Moscow itself cannot stay online, the message to the rest of the country is hard to miss.
4. Lukoil-Nizhegorodnefteorgsintez (NORSI) - Kstovo, Nizhny Novgorod OblastCapacity: ~17 million tons/year (Lukoil), Russia's second-largest gasoline producer
Struck: May 18 and May 20 (fourth strike on this plant in seven months)
NORSI at Kstovo, about 450 km east of Moscow, was the month's most-targeted refinery, hit on both May 18 and May 20 in what amounted to a fourth strike in seven months. The May 20 attack damaged the AVT-6 primary crude distillation unit - Russia's designation for CDU-6 - and started a fire confirmed by regional governor Gleb Nikitin. The significance is in that single unit: Meduza, citing Reuters industry sources, reported that CDU-6 alone accounts for 53% of the entire plant's processing capacity, so its loss roughly halved output at Russia's second-largest gasoline producer. NORSI supplies an estimated 30% of Moscow Oblast's gasoline, making it a direct lever on fuel availability in the most populous region of the country. The repeated targeting reflects a deliberate pattern: rather than spread strikes thin, Ukraine returned to high-value plants to keep them down while sanctions slow repairs.
5. Syzran Refinery - Samara OblastCapacity: 7–8.9 million tons/year (Rosneft)
Struck: May 21
President Zelensky announced the Syzran strike on May 21, and its headline feature was distance: the plant sits more than 800 kilometers from the Ukrainian border. Russian opposition outlet Astra reported a fire in the city's industrial zone, geolocated footage showed flames near the refinery, and NASA's FIRMS satellite system detected heat anomalies in Syzran that day. Samara Oblast governor Vyacheslav Fedorishchev acknowledged that drones struck industrial targets. Syzran produces gasoline, diesel, aviation kerosene, and bitumen, and by United24's account its CDU-6 unit was destroyed and the plant taken fully offline. The strike demonstrated that Ukraine could reach and disable mid-sized plants deep in the Volga region, expanding the threatened map well beyond the western refineries.
6. Lukoil-Permnefteorgsintez - PermCapacity: among Russia's largest
Struck: during May
The Perm refinery, located in the Ural Mountains, was among the ten facilities on Brovdi's list and was reported halted during the month. Perm is one of the deepest targets Ukraine has reached, far into Russia's industrial interior, and its inclusion showed the campaign was not confined to plants near the front or the export coasts - even Ural-region refining was now exposed.
7. Tuapse Refinery - Black Sea coastCapacity: major export-oriented plant (Rosneft)
Struck: four times across April and May (including ~May 28); indefinitely closed
Tuapse, a coastal resort and port on the Black Sea, absorbed four drone strikes across April and May and was described by Brovdi as indefinitely closed. Beyond lost output, Tuapse produced the month's worst secondary effect: an environmental disaster. The New York Times reported oil-stained rain, massive plumes of dark smoke, hazardous airborne toxin levels, and oil seeping into nearby waterways, with a longtime resident calling it the most significant oil spill on Russia's Black Sea coast in his lifetime. Russian authorities declined to estimate the spill but said about one million cubic feet of contaminated soil and stone had been removed from the shoreline. Because Tuapse supplies fuel to Russia's southern regions and its forces, its closure tightened the supply situation feeding the war in the south.
8. Kuibyshev Refinery - SamaraCapacity: not individually specified (Rosneft)
Struck: during May (part of capacity)
The Kuibyshev plant in Samara had part of its capacity struck during the month, per Brovdi's accounting. Clustered with Syzran in the Samara region, its targeting reinforced a pattern of pressuring entire refining hubs rather than isolated plants, compounding the regional disruption around the Volga.
9. Yaroslavl Refinery (Slavneft-YANOS) - YaroslavlCapacity: ~15 million tons/year (Russia's fourth-largest by volume)
Struck: mid-to-late May (around May 19 and again ~May 28–29)
The Yaroslavl refinery, the fourth-largest in Russia at roughly 15 million tons per year, was knocked down to about 25% of capacity during the month before later resuming work. As a top-tier plant feeding the Russian military machine, its temporary collapse to a quarter of output added meaningfully to the national shortfall even though it was not permanently disabled. Strikes in the area also hit an associated oil pumping station, part of Ukraine's widening focus on the pipelines and transfer nodes that move crude between facilities.
10. Volgograd Lukoil Refinery - VolgogradCapacity: ~15 million tons/year (one of Russia's ten largest, Lukoil)
Struck: late May (~May 28–29)
Casualties: drone strikes on Volgograd and Bryansk around May 29 killed 3
The Volgograd refinery, one of the country's ten largest and a key supplier to the occupation army in the south, was struck in late May. Ukraine's General Staff reported that the primary refining units AVT-1, AVT-3, AVT-5, and AVT-6, along with secondary units, were hit, and that the refinery halted production. Drone strikes on Volgograd and Bryansk around the same window killed three people, according to the Moscow Times. Russia's Defense Ministry claimed 28 drones intercepted nationwide on one of the late-May nights - again, a countrywide and unverified figure.
11. Saratov Refinery - Saratov CityCapacity: significant regional supplier (Rosneft)
Struck: May 24 and night of May 30–31
Ukraine's General Staff reported a strike on the night of May 30–31 that caused a large fire, and geolocated footage indicated damage to the ELOU-AVT-6 processing unit and two struck tanks. Saratov sits near the Engels strategic-bomber airfield and supplies fuel used by the Russian army, giving it both an economic and a direct military dimension. Its repeated targeting late in the month signaled that the campaign was not winding down.
Transport and Export Nodes
Alongside the refineries, Ukraine increasingly went after the network that moves crude and finished fuel. The Primorsk Baltic port was halted during May, and the Tamanneftegaz oil terminal on the Krasnodar coast was hit on May 13. At month's end, drones struck the Taganrog port in Rostov Oblast - hitting a tanker, a fuel storage tank, and an administrative building, with two civilians injured when a drone hit a private home, per Al Jazeera and governor Yury Slyusar. The Lazarevo oil pumping station in Kirov Oblast and a fuel-and-lubricants warehouse at Matveyev Kurgan in Rostov Oblast were both struck on the night of May 30–31, and seven pumping stations plus a linear dispatch station across Nizhny Novgorod, Ryazan, and Yaroslavl oblasts were hit in mid-May. As Brovdi put it, the campaign was visibly shifting from refinery hits toward the pipelines and pumping nodes that connect them.
Why These Targets
Oil and gas taxes make up roughly 25% of Russia's federal budget, and refineries are where crude becomes the high-value, taxable, exportable product that generates that revenue, so disabling refining squeezes Moscow harder than hitting crude extraction. Three motives overlapped throughout the month. First, deny Russia the windfall from the oil-price spike tied to Middle East supply disruptions - strikes were timed to stop Moscow capitalizing on higher prices. Second, starve the front: Saratov, Volgograd, and Tuapse directly fuel Russian forces in the south, and the squeeze fed into an acute fuel crisis in occupied Crimea, where authorities introduced rationing. Third, compound the damage over time - Western sanctions restrict Russia's access to the parts needed for repairs, so repeat strikes on plants like Kstovo kept them down far longer than a single hit would. The largest and highest-value plants were prioritized first, maximizing the capacity removed per strike.
Strategic Significance
Unable to match Russia weapon-for-weapon on the battlefield, Ukraine spent May taxing the economy that funds the war. The scale is captured in Reuters' running tally: about 700,000 barrels per day of refining capacity knocked out from January to May across 16 refineries - double the eight hit in the same period of 2025 - with 35 primary distillation units rendered inoperative this year against 12 a year earlier. The affected plants represent over 30% of Russia's gasoline output and roughly 25% of its diesel, and combined account for more than 83 million metric tons of annual refining capacity.
Russia's oil and gas revenue for January–May 2026 fell about a third year-on-year to roughly 3 trillion rubles ($42.1 billion). Even May's revenue, lifted 39% by high global prices to about 700 billion rubles ($9.8 billion), still dropped 17% from April. One honest caveat belongs in any sober assessment: the kinetic damage is verified and escalating, while the financial squeeze is partly cushioned by the elevated oil prices Russia is still able to capture. The strain on Russia's defenses is real too - authorities have begun authorizing private security firms to use firearms against drones at energy facilities, a sign of how thinly air defense is now stretched across an interior that was once considered safe.
Ukraine struck targets up to 1,000 miles inside Russia, from the Baltic coast to the Urals to the Volga, and demonstrated that no major refining region remains beyond the threat. The only significant oil route Ukraine has not yet touched runs to the port of Nakhodka on the Sea of Japan. For a country that cannot out-produce Russia in tanks and missiles, making every refinery, port, and pumping station a potential target - and forcing Moscow to defend all of them at once - is the heart of the strategy.
