Drone Attack on the Ryazan Oil Refinery
On May 15, drones struck the Ryazan oil refinery, with analysts estimating that 90 to 100 percent of the facility's processing capacity was taken offline. This refinery, part of the Rosneft company, ranks as Russia's third-largest by output, with an annual capacity of roughly 17 million metric tons of crude oil. In 2024, it processed 13.1 million tons, accounting for nearly 5 percent of the nation's total refining volume.
Fresh satellite photos have captured the extent of destruction at the Ryazan site following the drone assault. Damage was observed at the primary crude distillation units AVT-4 and AVT-3, and three petroleum product storage tanks located between these units were completely destroyed. Earlier assessments had already noted harm to the ELOU-AVT-3, ELOU-AVT-6, and AVT-1 units. A thick plume of smoke rose above the facility, and eyewitnesses reported hearing more than ten explosions.
Strategic Significance and Aftermath of the Attack
The Ryazan refinery produces all grades of automotive gasoline, diesel fuel, aviation kerosene, fuel oil, liquefied gases, bitumen, and petrochemical feedstock. It serves as the primary supplier of motor fuel to regions surrounding Moscow, and a significant portion of its output is channeled to military needs. In March 2024, a drone hit a primary processing unit, sparking a massive fire. In May 2024, Ukraine's Defense Intelligence (GUR) confirmed its involvement in another attack on the facility.
Ryazan, where the refinery is located, is considered the unofficial capital of Russia's airborne forces. The city hosts the Ryazan Guard Higher Airborne Command School named after General Margelov, which has been awarded the Order of Suvorov and two Orders of the Red Banner. The 137th Guard Parachute Landing Regiment is stationed nearby. In January 2025, the plant halted operations after drone strikes damaged a railway loading rack and a hydrotreatment unit.
The drone attack on the Ryazan oil refinery carries serious implications for Russia's energy security, given its critical role in supplying fuel, particularly for military purposes.
As a key component of the regional energy supply chain, the refinery's incapacitation could disrupt both civilian operations and military units. These events underscore the growing risks to infrastructure amid the ongoing conflict and signal an escalation of tensions in the area.
The recent drone strike on the Ryazan oil refinery highlights a troubling trend in attacks on Russian energy facilities. Similarly, the Syzran oil refinery was also targeted, raising concerns about the vulnerability of critical infrastructure across the country. As these incidents escalate, the implications for energy supply and regional security become increasingly significant.
