On Monday, July 6, 2026, a Ukrainian long-range drone strike halted operations at Gazprom Neft’s refinery in Omsk, according to a Grosswald analysis. The plant is Russia’s largest, at around 440,000 barrels a day.
The distance is the headline. Omsk sits about 2,500 kilometres from the border, which makes this one of the deepest attacks of the war and the first to reach the Siberian plant.
What the refinery means
Omsk handles roughly a tenth of Russia’s refining capacity. It also supplies more than half of the motor fuel used in the Siberian Federal District. A loss of output there is felt across a region with few alternatives.
Damage claims, and what Moscow says
Ukrainian and industry accounts say two primary distillation units went offline after the strike, which would be on the order of three-quarters of throughput. They also say the plant has suspended sales on the St Petersburg (SPIMEX) commodity exchange. None of that is independently confirmed. Grosswald stressed that the damage figures come from Ukrainian and trade sources.
Russia’s Defence Ministry says its air defences downed the drones. The Omsk governor conceded only that drones reached the northern industrial zone, and said there was a fire but no casualties. Footage of a large blaze, Grosswald wrote, is hard to square with a clean interception.
A wider two days of strikes
The refinery was one target among several. Ukraine’s Unmanned Systems Forces, commanded by Robert “Madyar” Brovdi, hit about a dozen tankers that Kyiv described as part of the sanctioned “shadow fleet.” Eight of them were in the Sea of Azov. Brovdi calls it a campaign to cut off fuel and ammunition to occupied Crimea, where rationing has already begun. By July 8, according to Grosswald, the tally had passed twenty vessels in three days.
