Not Targeted: Ukraine Struck Russia’s Last Major Oil Refinery
6 July 16:12
On Monday, July 6, Ukrainian drones attacked the Omsk Oil Refinery—Russia’s most powerful refinery and the last of the largest oil refineries that had not yet sustained damage from drone strikes. This was reported by "Komersant Ukrainian", citing Russian propaganda media.
Footage of the burning refinery, which has an annual capacity of 22 million metric tons, was published by monitoring channels. Vitaly Khotsenko, governor of the Omsk region, reported that “enemy UAVs” had been shot down over the region and that the consequences of the attack were “being assessed.” Rosaviatsiya announced restrictions for the first time at Omsk Airport, located 2,500 km from the border with Ukraine.

OSINT sources claim that the drones struck the ELOU-AVT-11 primary oil refining unit at the Omsk Oil Refinery, which has a capacity of 8.4 million metric tons per year (accounting for about 40% of the facility’s total capacity). According to eyewitnesses, the plant was attacked by seven drones, none of which were shot down.
The strike on the Omsk refinery was the most severe in a series of attacks on oil refineries, which caused oil refining in Russia to plummet to its lowest levels since the early 2000s, and regions from Kamchatka to the Kaliningrad Oblast have faced a fuel crisis. Last October, the Tyumen Oil Refinery, located 2,000 km from the border, was struck, and in early 2026, the Ukhta Oil Refinery (1,750 km away) was also hit.
After the attack on the plant in Omsk, there were no refineries left in Russia among the top 10 largest that had not been targeted by airstrikes this year. In May, the Kirishinefteorgsintez refinery in the Leningrad Oblast (capacity: 21 million metric tons) and the Ryazan Refinery (17 million metric tons) were attacked; in June, Lukoil’s “Nizhegorodnafteorgsintez” (16 million metric tons) and “Taneco”—Tatneft’s largest refinery in Nizhnekamsk (12.5 million metric tons)—were hit;
The Yaroslavl Refinery (15 million metric tons), which ranks sixth in capacity, was attacked in May and then again on July 6; the Volgograd Refinery (15 million metric tons) shut down on June 1 due to a drone attack. The Permnaftorgsintez plant was hit in late April and became infamous for the “oil rain” that fell in the region following a fire at the facility.
The Moscow refinery (12 million metric tons) shut down in June, and its repairs could drag on until 2027, according to Reuters sources. The Tuapse Oil Refinery, which rounds out the top 10, set a record for the number of attacks it has endured: it was attacked seven times.
