Ukrainian forces struck Russian energy facilities across a 1,700-kilometer operational range on May 13-15, hitting refineries and gas processing plants from Ryazan near Moscow to Astrakhan on the Caspian Sea, demonstrating sustained capability to disrupt Russian fuel production that finances the war effort.
The strikes represent the 27th and 28th hits on Russian oil and gas infrastructure in 2026, according to tracking by Ukrainian military observers, continuing a systematic campaign that has targeted over 100 facilities since the war's early days. The latest attacks focused on two strategically important sites: the Ryazan Oil Refinery and Gazprom's Astrakhan Gas Processing Plant.
In the early morning hours of May 15, multiple Ukrainian drones struck the Ryazan refinery, one of Russia's largest oil processing facilities with capacity to refine approximately 17 million tons of oil per year. The attack killed three people and injured 12, according to the regional governor, while causing significant damage to industrial facilities and nearby residential buildings.
The Ryazan facility, operated by Rosneft, produces automotive gasoline, diesel fuel, aviation kerosene, and other petroleum products for regions near Moscow. Thick black smoke was visible across the city following the strike, with residents reporting multiple explosions after 2 a.m.
Two days earlier, on May 13, Ukrainian drones struck the Astrakhan Gas Processing Plant, damaging a condensate processing unit with annual capacity of 3 million tons and destroying equipment for hydrogen sulfide removal and sulfur recovery. The facility suspended all automotive fuel production following the attack.
Before the strike, the Astrakhan plant had produced approximately 800,000 tons of gasoline and 600,000 tons of diesel annually. Russian officials estimated restoration could take representing a significant disruption to fuel supplies for southern .
