Ukraine hits Rostov airfield and Yaroslavl oil refinery in overnight strikes

Why it matters

The strikes demonstrate Ukraine's ability to hit both military aviation assets and a major Russian energy facility deep inside Russian territory in a single coordinated night operation. Slavneft-YANOS is one of Russia's largest oil refineries by capacity, processing approximately 15 million tons of oil per year, making it a strategically significant target. President Zelensky's public confirmation of both strikes signals continued high-level acknowledgement of long-range operations against Russian military and infrastructure targets.

What happened

On the night of September 17, Ukrainian drones struck targets in two Russian regions. In Rostov-on-Don, drones hit the "Rostov-on-Don — Centralny" military airfield, where a fire broke out near the aircraft parking area and secondary detonations were recorded. Governor Yurii Slyusar confirmed a "massive air attack" on the city but did not mention the airfield in his public statement, reporting only that drone debris damaged a transformer substation, cut electricity to four districts, and that the fire on the ground was "promptly extinguished" with no casualties. Russian air defense claimed to have shot down 50 drones over the oblast.

In Yaroslavl, drones struck the Slavneft-YANOS oil refinery, triggering a large-scale fire. Governor Mykhailo Yevrayev confirmed damage to the refinery and the fire, said there were no casualties, and reported that falling debris shattered windows in several apartment buildings and damaged cars. Russian air defense claimed 65 drones were shot down over the region. A section of the M-8 highway exiting Yaroslavl toward Moscow was closed after the attack.

President Volodymyr Zelensky publicly confirmed both strikes, stating that the SBU carried out the Rostov airfield attack with confirmed hits on one An-12, two An-26 aircraft and three helicopters, and that the Yaroslavl refinery strike was a joint operation of the SBU, the Unmanned Systems Forces, military intelligence (HUR) and the Foreign Intelligence Service (SZR). Zelensky also mentioned "good results" in the Black Sea in the same announcement. Telegram channels ASTRA and Exilenova+ provided initial reporting on the airfield strike and secondary detonations in Rostov.

How Ukrainian sources describe it

Ukrainian sources lead with President Zelensky's confirmation and frame the strikes as successful Ukrainian operations. They emphasise the destroyed aircraft — one An-12, two An-26s and three helicopters — and the refinery hit as tangible battlefield gains. Ukrainian agency reporting adds detail about the joint SBU, Unmanned Systems Forces, HUR and SZR authorship of the refinery strike, presenting it as a coordinated inter-agency effort.

Where reporting differs

Sources differ on the size ranking of the Slavneft-YANOS refinery: one describes it as Russia's sixth-largest oil refinery by capacity, while another places it among the five largest.

Background

The Slavneft-YANOS refinery had already been struck at least eight times earlier in 2026 before this incident, on dates including March 28, April 26, May 8, May 22, July 6, July 16, August 6 and August 28. 99.7% of Slavneft shares are controlled by Rosneft and Gazprom. Zelensky paired his announcement of these strikes with a separate note about positive results in the Black Sea. Earlier in September, Ukrainian drone strikes had halted operations at Rosneft refineries in Syzran and Saratov, and a September 12 attack struck an airfield in Taganrog.
