A fire at a Russian military-linked refinery broke out overnight on 22 July after Ukrainian drones targeted industrial sites in Russia’s Samara Oblast about 1,000 km from Ukraine. The targeted facility was the Novokuybyshevsk Petrochemical Company, one of Russia’s largest producers in the petrochemical and organic synthesis sectors. The facility plays a role in Russia’s weapons production by supplying raw materials used in artillery shells, aviation bombs, and other munitions.

Ukrainian drones hit explosives-linked chemical plant in Samara

Ukrainian Telegram channel Exilenova+ reported that the Ukrainian Unmanned Systems Forces’ attack targeted the Novokuybyshevsk Petrochemical Company, which operates facilities producing chemicals such as benzene, acetone, phenol, and olefins. The Russian news Telegram channel Astra confirmed that drones hit the Novokuybyshevsk refinery, a Rosneft-owned site producing over 20 fuel types, including high-grade jet fuel and automotive oils.

Astra said that following the strike, a fire broke out at the facility and was later extinguished. Samara Oblast authorities acknowledged an attempted attack and claimed that several drones were shot down, while also imposing temporary mobile internet restrictions to assist military efforts in countering UAVs.

Drones target Russian airbase used for Shahed launches

Late on 21 July, Astra reported drone strikes on the Millerovo military airfield in Rostov Oblast. The airbase is frequently used to launch Shahed-type drones toward Ukrainian territory. The Iranian-designed Shahed drones can carry up to 90 kg of explosives, and Russia has been widely using them in its daily attacks against Ukrainian civilians.
