Core Event
During the night of 25-26 April 2026 Ukrainian forces launched a coordinated long-range drone campaign against two Russian-controlled sites. A strike ignited a fire at the Yaroslavl Oil Refinery’s ELOU-AT-4 processing unit. Simultaneously, drones hit the Black Sea Fleet’s Sevastopol naval base and the Belbek airfield, damaging the landing ships Yamal and Filchenkov, the intelligence-gathering vessel Ivan Khurs, a MiG-31 interceptor, the MR-10M1 “Mys-M1” coastal radar station and related command facilities. Geolocated video released on 26 April shows flames at the refinery, while satellite imagery displays damage to the landing ships and the Belbek installations.
Context and Scale
Ukraine’s strike program, intensified since March 2026, aims to exploit gaps in Russia’s overextended air-defence network. The Yaroslavl refinery processes 15 million tonnes of crude annually, producing gasoline, diesel and jet fuel. Open-source monitoring recorded at least ten oil-and-gas strikes across Russia between 12 April and 26 April. The Sevastopol raid involved 71 Ukrainian drones, while Russia launched 144 drones toward Ukraine the same night. The operations were attributed to the SBU’s “Alpha” special unit, led by acting head Yevhenii Khmara; Unmanned Systems Forces commander Robert “Magyar” Brovdi cited a parallel strike on a Russian FSB post in Donetsk, and Sevastopol governor Mikhail Razvozhaev confirmed the 71-drone sortie.
Official Statements & Responses
The SBU’s April 26 communique described the operation as executed by the Alpha unit using drones to strike Sevastopol facilities and the Belbek airfield. Khmara emphasized a logic of systematically destroying fleet, aviation, reconnaissance and air-defence elements. The Ukrainian General Staff confirmed the Yaroslavl refinery fire and reiterated that Russia’s air-defence system remains overstretched.
Conflicting Reports & Gaps
Independent verification of damage to the naval vessels and the MiG-31 relies solely on Ukrainian and SBU sources; Russian authorities have not released casualty or damage assessments, leaving the exact operational impact unconfirmed.
