Ukrainian forces struck Russian oil infrastructure in Krasnodar and Perm krais and Orenburg Oblast between April 29 and May 1, including a strike against the Tuapse Oil Refinery for the fourth time since April 1. The Ukrainian General Staff and Unmanned Systems Forces (USF) officials reported on May 1 that Ukrainian drones struck the Tuapse Oil Refinery in Krasnodar Krai overnight on April 30 to May 1 after previously striking the refinery on the nights of April 15 to 16, 19 to 20, and 27 to 28. The Ukrainian USF reported that they are still conducting the battle damage assessment (BDA) for the strike, but that the previous Ukrainian strikes on Tupase Oil Refinery destroyed at least 24 tanks, damaged at least four more, forced the plant to suspend operations, and caused several fires that took days to extinguish. Satellite imagery and geolocated footage published on May 1 show fires burning at the refinery. The Krasnodar Krai Operational Headquarters acknowledged that Ukrainian drone strikes caused a fire at the port of Tuapse on May 1. The Ukrainian General Staff reported on May 1 that Ukrainian forces also struck the Permsky Oil Refinery in Perm Krai on the night of April 30 to May 1, causing a fire and damaging the AVT-4 primary oil refining unit. The Ukrainian General Staff confirmed on April 30 that Ukrainian forces also struck the Orsknefteorgsintez Oil Refinery in Orenburg Oblast on April 29, causing a fire.

The Ukrainian General Staff confirmed that Ukrainian forces recently struck several Russian aircraft up to 1,676 kilometers from the international border. The Ukrainian General Staff reported on May 1 that Ukrainian forces struck several Russian Su-57 fighter jets and Su-34 fighter-bombers at the Shagol Airfield in Chelyabinsk Oblast, approximately 1,676 kilometers from the international border, on April 25. Satellite footage posted on May 1 confirms that the April 25 strikes damaged multiple planes at the Shagol Airfield. Ukrainian forces also struck Mi-28 and Mi-17 helicopters at an airfield near Babky, Voronezh Oblast (roughly 150 kilometers from the frontline) on April 29 or overnight on April 29 to 30.

Ukrainian strikes on Russian oil infrastructure degraded the average output of Russian oil refineries to their lowest level since December 2009. Bloomberg reported on April 30 that data from analytics firm OilX indicates that the average output of a Russian oil refinery dropped to an average of 4.69 million barrels a day, the lowest daily processing average since December 2009. Ukrainian forces have notably been escalating their strike campaign against Russian oil assets in March and April 2026.
