Ukrainian drones ignite fires at major Yaroslavl oil refinery as Russia admits fourth plant hit in recent days
Ukrainian long-range drones struck the Slavneft-YANOS refinery in Yaroslavl, causing large fires at a plant that processes about 15 million tons of oil a year. Russian forces say electronic warfare and air defenses repelled most of 124 incoming drones but acknowledge some reached the site, making this the fourth refinery reported damaged in recent days.
As Russia carried out wide-ranging strikes on Ukrainian energy infrastructure, Ukraine hit back deep inside Russian territory, targeting one of the country’s major oil refineries in Yaroslavl.
Ukrainian long-range drones attacked the Slavneft-YANOS oil refinery in the city of Yaroslavl, with reporting from Ukrainian sources stating that the strike led to multiple large fires at the facility. The plant’s annual processing volume is about 15 million tons of oil, which makes it a significant refining site in Russia’s energy system.
Russian accounts say electronic warfare and air defense forces engaged a large wave of incoming drones over the refinery, reportedly 124 Ukrainian drones in total. According to these reports, most of the drones were repelled, but some managed to get through. Russian sources confirm that the refinery sustained damage.
The Yaroslavl site is described as the fourth oil refinery damaged in recent days, according to the same Russian reporting. While the other affected facilities are not detailed in the available material, this admission points to a campaign that is hitting multiple refining assets rather than a single isolated incident.
For people in and around Yaroslavl, fires at a refinery of this size carry immediate safety risks and can temporarily disrupt local fuel supply. For refinery workers, damage raises questions about how long units will remain offline and what that means for income and job security.
Refineries of this scale serve wider economic and military needs, supplying fuel for vehicles, industry and the armed forces. Even limited damage can force temporary shutdowns of specific units, rerouting of fuel flows or delays in deliveries to customers further down the chain.
From Ukraine’s perspective, the strike on Yaroslavl demonstrates the use of long-range drones to hit high-value targets far from the front line. For Russia, it underscores the challenge of defending industrial infrastructure even when large numbers of air defense and electronic warfare systems are deployed.
In the short term, the key indicators to watch will be how Russian officials characterize the extent of the damage, how long the reported fires continue, and whether there are any public statements about reduced output or repair timelines. Any follow-on Ukrainian drone activity against refineries or other energy facilities inside Russia will show whether this was a single high-profile operation or part of an extended campaign against refining capacity.
