Ukrainian forces launched one of their most far-reaching drone operations of the war, striking a strategic Russian bomber base more than 800 kilometers from the front line and setting fire to one of Russia’s five largest oil refineries in a coordinated overnight attack. The August 28 strikes targeted the Engels-2 military airbase in Saratov Oblast and the Slavneft-YANOS refinery in Yaroslavl, hitting both Russia’s strategic aviation capability and its domestic fuel supply chain in a single operation.
At Engels-2, long-range drones operated by the SBU Alpha special forces unit struck a Tu-95MS strategic missile carrier. President Volodymyr Zelensky confirmed the strike, saying the damaged bomber is one of the aircraft Russia uses to launch cruise missile attacks against Ukraine. Satellite imagery published by analysts from the AviVector group showed significant structural damage to the aircraft’s right wing, with part of the wing assembly appearing to have broken away. Analysts assessed the bomber as beyond repair, marking the second Tu-95MS destroyed at the same base in roughly six weeks. A similar strike on July 16 left another Tu-95MS with its tail section completely destroyed.
The Engels-2 airbase is one of Russia’s most important installations for long-range strategic aviation. Tu-95MS and Tu-160 bombers operate from the facility, which sits more than 600 kilometers from Ukrainian-controlled territory. The Tu-95MS carries Kh-101, Kh-555, and Kh-55 cruise missiles used in mass strikes against Ukrainian cities. The SBU also reported striking an ammunition depot and a fuel storage facility at the airbase during the same operation.
Simultaneously, Ukrainian drones attacked the Slavneft-YANOS refinery in Yaroslavl, located approximately 250 kilometers northeast of Moscow. The General Staff of Ukraine’s Armed Forces confirmed the strike, which marked the eighth attack on the facility in 2026 and the 21st reported strike on a Russian refinery in August alone. Verified footage showed multiple fires burning across the plant’s territory after the attack.
Civilian Toll and Regional Disruption
Yaroslavl Oblast Governor Mikhail Yevraev reported one person killed and 27 injured in the regional strikes. Ten of the injured were hit by falling drone debris while riding a bus. Debris also damaged industrial infrastructure, residential buildings, and shops in surrounding areas. Authorities ordered the closure of at least two kindergartens and restricted traffic on the M8 highway toward Moscow. Public transport routes were adjusted to accommodate the emergency response.
The Slavneft-YANOS refinery is a joint venture between Russian state energy companies Rosneft and Gazprom Neft. It processes approximately 15 million metric tons of oil per year, producing Euro-5 gasoline, diesel fuel, aviation kerosene, and other petroleum products that supply Moscow and the surrounding central Russian regions. The facility represents one of the largest refining assets in the country, and its repeated targeting has drawn growing attention from energy markets.
Russia Defenses Strained by Record Drone Waves
Russian air defenses claimed to intercept 512 Ukrainian drones in a single night across Russia and annexed Crimea, one of the highest single-night totals reported since the full-scale invasion began. Despite the claimed interceptions, falling debris caused fires and damage in multiple locations. Moscow Mayor Sergey Sobyanin said two drones heading toward the capital were shot down, while a column of black smoke was reported over the town of Pavlovsky Posad, about 65 kilometers east of Moscow. Separate attacks in the Belgorod region killed two people and injured nine others.
On August 30, Ukrainian forces continued the campaign with strikes on a major oil facility in Leningrad Oblast and an airbase in Krasnodar Krai, according to monitoring channels. The sustained pace of operations throughout late August has pushed Russia’s refining capacity to a 20-year low, according to ISW analysis. Moscow has responded by extending bans on gasoline and jet fuel exports through the end of 2026 and by turning to Kazakh refineries to ease domestic fuel shortages.
Ukraine considers Russian energy infrastructure a legitimate military target, arguing that oil facilities generate the revenue and fuel that sustain Moscow’s war effort. The record-breaking frequency of refinery strikes in August, combined with attacks on strategic military assets like the Engels-2 bomber base, signals a deliberate strategy to degrade both Russia’s ability to project air power and its capacity to finance continued operations.
