Ukraine’s Strikes on Kirishi Refinery and Yeysk Airfield Push War Deep Into Russia
Ukrainian forces say they hit the Kirishi oil refinery in Russia’s Leningrad region and destroyed air defenses and an arms depot at the Yeysk airfield, taking the war hundreds of kilometers behind the front. The targets include fuel and air defense sites that help sustain Russia’s campaign in Ukraine.
Russia’s rear is looking less like a sanctuary and more like another front line. Ukraine’s military says it has struck a major oil refinery in Russia’s Leningrad region and knocked out air defenses and an ammunition depot at the Yeysk airfield on the Sea of Azov, pushing deep-strike warfare far beyond the immediate battlefield.
Ukraine’s Special Operations Forces said overnight that their Deep Strike units, working with the Security Service (SBU), the newly formed Unmanned Systems Forces and military intelligence, attacked the Kirishi oil refinery in Leningrad region. The plant processes around 20 million tons of oil a year and produces gasoline, diesel and aviation fuel.
Separately, Ukrainian Defense Forces reported using FP-1 drones to destroy a Pantsir-S1 air defense system, a Sopka-2 radar station and an aviation weapons depot at the Yeysk airfield. Open-source geolocation and NASA’s FIRMS satellite fire-detection data indicated fires at at least three spots on the base after the strike, supporting claims that multiple targets were hit.
Moscow has not publicly confirmed damage at Kirishi or at Yeysk, and independent access to the facilities is limited, but the choice of targets is telling. Refineries like Kirishi are critical nodes in Russia’s logistics chain: every disrupted batch of aviation fuel complicates sortie planning, and every interruption in diesel output ripples through military transport and civilian freight.
For Russian pilots and ground crews at Yeysk, the reported destruction of a Pantsir battery and radar would have immediate tactical effects. Pantsir systems are designed to shoot down incoming missiles and drones, while ground-based radars like Sopka-2 help manage air traffic and contribute to the local air picture. Losing both, along with a weapons depot, would leave aircraft and munitions more exposed to follow-on attacks and force commanders to reallocate air defense assets from other sites.
For civilians on both sides of the border, the campaign carries a different risk. Strikes on oil infrastructure heighten the possibility of fires, toxic smoke and disruption to fuel supplies. Even when precise weapons are used, the potential for industrial accidents and long clean-up operations is real. At the same time, Ukrainian cities are facing their own waves of attacks from Russian drones and missiles, turning critical infrastructure into shared targets in a war of endurance.
Strategically, the twin strikes fit a pattern of Ukraine pushing the conflict deeper into Russian territory, using drones and long-range systems to impose costs far from the front. Hitting a refinery in the Leningrad region reaches into Russia’s heartland and reminds the Kremlin that keeping the war running requires not only soldiers and tanks, but also secure industrial capacity and air defense coverage across a vast area.
The Yeysk attack also points to a changing balance in the air war. As Ukraine fields more indigenous drones and coordinates their use with intelligence services, Russian airfields once assumed to be relatively safe staging grounds now face recurring harassment. Each successful strike forces Russia either to disperse aircraft further from Ukraine, lengthening flight times, or to concentrate more air defense systems around bases, thinning coverage elsewhere.
In this phase of the war, fuel depots and radar sites matter as much as front-line trenches, because they shape how long the fighting can be sustained and at what tempo. Deep strikes turn logistics and air defense networks into contested terrain, not background infrastructure.
What happens next will depend in part on Russia’s response. Tighter security and camouflage at refineries and airbases, visible redeployment of air defense units, or new waves of retaliatory strikes on Ukrainian infrastructure would all signal that Moscow sees these attacks as a serious shift. For Ukraine, further confirmed hits on high-value targets deep inside Russia would show that its long-range campaign is moving from symbolic raids to a sustained effort aimed at the foundations of Russia’s war machine.
