Six explosions, four fires: Ukraine hit one of Russia’s five largest refineries, 700 km from border

Ukraine reached one of Russia's largest refineries and hit its coast guard in occupied Crimea in one operation. The Security Service of Ukraine (SBU), together with the Defense Forces, struck the Slavneft-YANOS refinery in Yaroslavl, over 700 kilometers from Ukraine's border, the SBU reported.

The refinery is a major node in Russia's fuel supply to its capital region. The Yaroslavl refinery is one of the five largest oil-refining enterprises in Russia, with a capacity of nearly 15 million tons of oil per year, producing gasoline, diesel, aviation kerosene, and other strategically important products for central Russia and the Moscow metropolitan area.

The refinery took multiple hits

The strike set several parts of the plant on fire. At least six explosions were heard on the refinery's grounds, and fires broke out in four different parts of the plant.

The damage hit both storage and processing. According to preliminary information, four crude oil tanks were damaged, resulting in a spill. Two tanks were engulfed in fire, and key processing units were also damaged and set alight. Striking both the tanks that hold the crude and the units that refine it degrades the plant's ability to produce fuel, not just store it.

The Kerch strike hit FSB coast guard ships

The second target was in occupied Crimea. Drone strikes on the port in Kerch damaged two Project 10410 "Svetlyak" patrol ships of the FSB coast guard, the "Balaklava" and the "Kerch".

Hitting the FSB's patrol vessels chips at Russia's ability to guard the waters around occupied Crimea and the Kerch Strait, the same maritime chokepoint Ukraine's shadow-fleet campaign has targeted.

The strikes fit the campaign against Russia's war economy

The operation extends Ukraine's sustained effort to drain Russia's fuel revenue and military logistics. The SBU said it consistently works to reduce Russia's military-economic potential, and that military sites, fuel-and-energy enterprises, and other legitimate targets working for Russia's aggression will keep coming under fire.
