President of Ukraine Volodymyr Zelenskyy said exactly what weapons the Defense Forces used to strike Russian oil refineries. According to him, the Omsk Refinery was attacked by FP-6 drones (modified FP-1 drones). An-196 RS unmanned aerial vehicles (part of the family of Ukrainian long-range "Liutyi" drones) were used to strike the Ukhta Refinery, UNN reports.
Omsk Refinery is Russia's largest oil refinery, with a capacity of about 22 million tonnes of oil per year. It is located approximately 2,500 km from the Ukrainian border in Russia's Omsk region. The facility is owned by the Russian company "Gazprom Neft." It produces gasoline, diesel and aviation fuel, lubricants, and other petroleum products.
Another target of the Armed Forces of Ukraine, the Ukhta Refinery, is located 1,900 km from the Ukrainian border in the Komi Republic. The facility is owned by the Russian company "Lukoil" and processes about 4.2 million tonnes of oil per year. The refinery produces gasoline, diesel fuel, fuel oil, and other petroleum products.
According to the General Staff of the Armed Forces of Ukraine, both facilities are involved in supplying the Russian army.
The president also confirmed the strike on another Russian data center, calling it a mirror response to Russia's strikes on Ukraine. The defense company Fire Point, whose drones were used by the Defense Forces to hit the target, said that it was the largest data center of the Russian company "Yandex" — "Yandex DC Kaluga." It is located in the Grabtsevo industrial park in Russia's Kaluga region.
