On the night of August 4, Ukrainian drones attacked the Syzran oil refinery in Russia's Samara region, according to Andrii Kovalenko, head of the Center for Countering Disinformation at the National Security and Defense Council.
"The Syzran oil refinery is out of commission," Kovalenko wrote.
According to the monitoring Telegram channels Exilenova+ and Supernova+, a series of explosions was heard in Syzran. A column of thick smoke rose above the refinery grounds.
As of this writing, there have been no official comments from Russian authorities regarding the extent of the damage.
Why Syzran oil refinery is important to Russia
The Syzran oil refinery is part of Rosneft and is one of the largest oil refining facilities in the Samara region. The decision to build it was made as far back as 1939, making it one of Russia's oldest oil refineries.
The facility is located on the Volga River, over 800 kilometers from the Ukrainian border. Together with the Kuibyshev and Novokuibyshevsk refineries, it forms part of the Samara oil refining hub.
The refinery’s nominal capacity is up to 8.9 million metric tons of crude oil per year. It produces gasoline, diesel fuel, fuel oil, and jet fuel, which Russia uses to supply Russian forces on the front lines, as well as some of the country’s central regions.
Not the first attack on refinery
The Syzran oil refinery has been targeted by Ukrainian drones on multiple occasions. Previous strikes on the facility were recorded in December 2025, as well as in March, April, and July 2026.
On May 21, a drone attacked one of the plant’s primary oil refining units. Following the strike, the CDU-6 unit—which accounts for over 70 percent of the plant’s capacity—was shut down; it took more than a month to resume operations.
That same night, drones attacked Wildberries warehouses in Chekhov, near Moscow, and in the village of Krasny Bor in the Leningrad region. In Krasny Bor, a logistics complex covering more than 150,000 square meters was damaged, and in Chekhov, the strike sparked a fire in a residential area.
Russia has significantly stepped up its use of A-50U long-range early warning aircraft, fearing Ukrainian cruise missiles.
On July 7, four such aircraft took to the air simultaneously—effectively the entire operational fleet of Russia.
