Ukraine’s Deep-Strike Drone Campaign Hits Russian Oil and Electronics Plants, Raising Industrial War Costs
Ukrainian drones struck a major oil refinery in Perm, an electronics plant in Ulyanovsk and a synthetic rubber factory in Voronezh in a coordinated wave reaching deep inside Russia. The attacks target refineries and defense-linked industry that feed Moscow’s war machine, while also triggering Russian claims of mass drone shootdowns over its own territory.
Russia woke up on 25 September to a mirror image of the night it had just inflicted on Ukraine: fires at industrial plants, damage to critical facilities, and official statements tallying downed drones across several regions.
Ukrainian long-range drones hit the Permnefteorgsintez oil refinery in the city of Perm on Tuesday morning, triggering several large fires, according to visual evidence and local reporting. The facility is Russia’s seventh-largest refinery, able to process up to 13 million tons of crude a year, making it a critical node in domestic fuel supply and export flows that generate foreign currency and tax revenue for the Kremlin.
At roughly the same time, a separate wave of Ukrainian drones struck the Iskra Electronics Plant in Ulyanovsk. Footage from the scene shows at least six consecutive impacts on different sections of the sprawling facility. Iskra specializes in electronic components, radio-electronic equipment and communications systems for both military and civilian sectors—a type of dual-use plant that has become a priority target as Ukraine tries to slow Russia’s capacity to equip and repair its forces.
Other strikes rounded out the night’s industrial targeting. In Voronezh, Ukrainian drones hit the Voronezhsintezkauchuk synthetic rubber plant, a producer of thermoelastoplasts and synthetic rubber used in everything from tires to industrial seals. In Russian-controlled Luhansk city, mid-range Ukrainian drones hit the Stroycenter shopping center, causing a large fire. While the mall is a civilian site, the Luhansk region serves as a logistical hub for Russian operations in eastern Ukraine, and Ukrainian planners have repeatedly targeted economic infrastructure there that they see as embedded in the occupation.
Russia’s Defense Ministry, for its part, said its air defenses shot down 592 Ukrainian drones overnight over Russian regions and the Black Sea. It reported large-scale attacks on Ulyanovsk, Voronezh, Perm and Rostov regions and said ten drones headed toward Moscow were destroyed, prompting temporary flight restrictions at Vnukovo and Domodedovo airports. In Ulyanovsk region, authorities acknowledged damage to industrial and civilian infrastructure, including residential buildings, and said eight people, among them a child, were injured.
For ordinary Russians, the immediate effect is unnervingly familiar to what Ukrainians have endured for more than two years: explosions in the night, damage to homes and factories, and airports briefly closed as air defense batteries fire overhead. For workers at plants like Permnefteorgsintez or Iskra, the strikes raise new questions about job security and physical safety in facilities that, until recently, felt far from the front.
Strategically, Ukraine is signaling that no segment of Russia’s war economy is fully out of reach. Refineries are an especially attractive target. They produce the diesel and aviation fuel that power Russian armored vehicles, aircraft and logistics, and they represent concentrated, often lightly defended stationary assets. Disruptions don’t need to be permanent to matter; forced shutdowns for inspection and repair can tighten fuel supplies, raise transport costs and compel Moscow to divert air defenses away from the front lines to protect deeper infrastructure.
Hitting electronics and synthetic rubber factories carries a different but related logic. Electronics plants feed into communications, drones, guided munitions and battlefield sensors, while rubber and polymers underpin vehicle tires, seals and a host of military-industrial components. Each damaged plant adds friction and delay to Russia’s effort to sustain high operational tempos in Ukraine.
The strikes also show how quickly the character of the war is shifting into a contest of industrial resilience and air defense coverage over thousands of kilometers. Long-range, relatively cheap drones allow Ukraine to hit targets once reserved for cruise missiles, while forcing Russia to spread sophisticated air defense systems across oil hubs, industrial cities and political centers like Moscow.
The memorable lesson for both sides is stark: industrial depth is no longer a sanctuary when drones can cross borders at scale. Indicators to watch now include the duration of shutdowns at the Perm refinery and Ulyanovsk electronics plant, any visible rerouting of Russian fuel logistics, new defensive deployments around refinery clusters and major plants, and whether Ukraine expands this campaign to additional nodes in Russia’s energy and defense supply chains.
