Ukraine says it struck Russia’s Svetlyak-class warship in Kerch

Ukraine hit a Russian warship at its own dock in Crimea. Ukraine’s Defense Forces struck a Project 10410 Svetlyak-class patrol ship at Kerch, along with tankers, a refinery 700 kilometers inside Russia, and a string of fuel and logistics targets over 16 July and the night into 17 July, Ukraine’s General Staff reports.

Most consequential hit was far to the north

Ukraine also struck the Slavneft-YANOS refinery in Yaroslavl on 16 July, recording an impact followed by fire on the plant’s grounds.

YANOS is one of Russia’s five largest refineries and the biggest in the country’s central region, processing about 15 million tons of crude a year into gasoline, diesel, jet fuel, lubricants, and bitumen, including products that feed Russia’s military-industrial complex and armed forces.

Ukraine has struck YANOS repeatedly throughout 2026 and keeps returning to it, part of a campaign the General Staff says has idled 42.74% of Russian refining and cost the industry $13.5 billion since August 2025.

The degree of damage at YANOS and the results of the other strikes are still being assessed, the General Staff said.

Ukraine hit tankers and gas carrier in Black and Azov seas

Beyond the ships already named, Ukraine struck two tankers — one of them a gas carrier — and a tug in the Black and Azov seas. The tankers move Russian oil, petroleum products, and liquefied gas around nternational sanctions, and carry fuel for the Russian armed forces.

The naval strikes fit a widening Black Sea campaign.

Ukraine has been hitting Russian tankers, warships, and port infrastructure night after night, driving toward the isolation of occupied Crimea and squeezing the shadow fleet Moscow uses to keep oil revenue flowing under sanctions.

Additionally, Ukraine hit the “TES-Terminal-1” oil terminal and a fuel-and-lubricants depot in Kerch, occupied Crimea, and the “Shakhtarsk” oil depot in Shakhtarsk, Donetsk Oblast.

The Kerch strikes compound a fuel squeeze already choking the peninsula. Ukraine’s counter-logistics and energy campaign has forced occupied Crimea to halt civilian fuel sales, ration gasoline, and declare a peninsula-wide state of emergency, as strikes on terminals, substations, and the Kerch Bridge cut the routes that keep Crimea supplied from Russia.
