Ukrainian forces hit the Omsk oil refinery overnight, the General Staff said on July 6, and a fire broke out at the site. Omsk lies nearly 2,500 kilometers (around 1,550 miles) from Ukraine’s border. Few targets sit farther out.
The mechanics matter here. According to the General Staff, preliminary information points to the ELOU-AVT-11 primary oil refining unit, which has a design capacity of 8.4 million metric tons of crude oil per year. That is the front end of the plant, where crude first gets split into fractions. Damage to it can hold up everything fed downstream. The military said the extent of the damage was still being assessed.
What Omsk does
The refinery is Russia’s largest by capacity and processes more than 21 million metric tons of crude oil per year. Its output covers fuels, lubricants and petrochemical products, and the General Staff said it is involved in supplying the Russian military. The military also put its refining depth at around 99%, one of the highest rates in Russia.
The General Staff added a detail that shows the pattern. Omsk was the last of Russia’s 11 largest gasoline producers to be hit by Ukrainian forces.
A busy night for the energy sector
Omsk was not alone. Ukraine’s Security Service (SBU), working with other branches of the Defense Forces, reported a series of strikes on Russian energy infrastructure and on military targets in occupied Crimea.
Drones struck the Yaroslavl oil refinery and the Yaroslavl oil pumping and dispatch station, and the SBU said explosions and smoke were reported near the refinery. At the port of Vysotsk in Leningrad Oblast, an oil terminal took damage: two oil loading arms were disabled and three storage tanks for petroleum products were hit. A fire followed explosions at the First Plant oil refinery in Kaluga Oblast.
Fuel supply to Crimea was a target too. Commander Robert “Madyar” Brovdi of the Unmanned Systems Forces said his units struck two shadow fleet tankers in the Sea of Azov that carried 7,000 metric tons of fuel between them for the occupied peninsula. He compared the load to roughly 200 rail tank cars. Crimea is already short of fuel, and the authorities there suspended fuel sales entirely on June 21.
The SBU described a separate operation in Crimea. Drones hit three aircraft hangars at the Hvardiiske airfield, a Pantsir-S2 air defense system near Simferopol and a mobile fire group in Kerch. A petroleum storage tank and a pumping station at the TES-Terminal-1 oil depot were also struck. Brovdi added that from July 1 to 5, Unmanned Systems Forces drones hit 37 energy nodes across occupied Crimea and other Russian-occupied territories in southern Ukraine.
SBU chief Yevhenii Khmara framed the campaign as payback. “We are doing everything to ensure that Russia pays every day for its crimes,” he said, adding that Russia’s military and fuel infrastructure “will continue to suffer significant losses” while the enemy shells Ukrainian cities.
The strikes came the same day Russia launched another massive overnight attack on Kyiv. It was the second large-scale assault on the capital in four days, and it killed at least 19 people and injured dozens more.
