Drones set Russia’s Syzran refinery ablaze 800 km from the war zone — analysts count every primary unit hit

Ukrainian FP-1 strike drones set Russia's Syzran oil refinery burning on 12 July, and the damage to the facility may be the campaign's largest single result in months, Ukrainian OSINT analysts assessed. Analysis of footage shared by local residents points to hits on every primary crude processing unit at the Rosneft plant. The facility, some 800 km from the warzone, has burned many times before.

Fire before dawn

The attack came in the night and morning of 11–12 July, with footage of the strikes appearing from around 4:30 a.m., monitoring Telegram channels Supernova+ reported along with Exilenova+ and others. A large fire broke out on the refinery grounds and was still burning as of 7 a.m. Kyiv time, per local residents' photos and videos. OSINT channel Dnipro Osint assessed that the strike probably damaged the ELOU-AVT-5 installation, which provides up to 30% of the plant's primary processing. Russian news Telegram channel Astra confirmed through its own OSINT analysis that the fire burned on the Syzran refinery's territory. 

"100% of primary processing capacity"

OSINT channel Cyberboroshno went further, mapping the damage to three key units, coordinates included. The FP-1 drones hit the AVT-5 primary processing unit (2.6 million tons a year, 30% of primary capacity) and the AVT-6 unit (6.3 million tons, the remaining 70%). A third hit landed on the LCh-35/11-600 catalytic reformer, which makes essential gasoline components.

The hit on the reformer, the channel noted, was accidental. The video shared by Exilenova+ shows the unit's stack suddenly appearing in a drone's flight path, triggering an airburst of the warhead directly above the installation. The shrapnel cloud shredded the unit, which later footage shows on fire — an accident that worked in Ukraine's favor.

The sum, per Cyberboroshno: 100% of the plant's primary processing capacity damaged, a combined 8.9 million tons a year. With no crude distillation running, the analysts noted, the refinery produces nothing at all. By the volume of capacity hit, the channel called it possibly the biggest single result of recent months — larger than the strike on the AVT-11 unit at the Omsk refinery, estimated at 8.4 million tons at the time of that attack.

A plant that keeps burning

The refinery is a veteran target. Drones struck it on 21 May 2026, seriously damaging the AVT-6 unit — then responsible for over 70% of the plant's capacity — and forcing a prolonged full stop. Reuters reported on 25 May, citing sources, that the plant had suspended operations. An earlier attack came on 18 April, and drones hit the plant three times in August 2025 alone. The 21 May attack was already the 11th strike on Syzran.
