**Deck**: Ukrainian FP‑1 and jet-powered drones hit the Ilsky Oil Refinery in Russia’s Krasnodar Krai overnight, causing a major fire at a plant used to supply Russian forces, while Ukrainian forces also reported strikes on an ammunition depot in Sievierodonetsk, a P‑18 Terek radar near Semenivske, and a defense-linked facility in Azov.

Ukraine is stretching the war deep into Russian territory with a wave of strikes on fuel, ammunition and radar assets.

Overnight on 26 September, FP‑1 long-range drones and jet-powered drones attacked the Ilsky Oil Refinery in Russia’s Krasnodar Krai. Ukraine’s General Staff confirmed that Defense Forces had struck the refinery and that a fire was recorded at the facility. Reporting from the area described a large blaze and stated that at least three civilians were killed and two others injured in the attack.

The Ilsky refinery processes about 6.6 million tons of oil a year and handles reception, storage and processing of hydrocarbons. According to Ukraine’s General Staff, its petroleum products are used in part to supply Russian troops. Damage there forces Russia to cope with disrupted fuel flows and repairs at a plant that feeds its military logistics.

In Russia’s Rostov region, Governor Yuri Slyusar reported a Ukrainian drone attack on the town of Azov. Local residents said the Azov Optical-Mechanical Plant, which produces goods for the defense industry, was targeted. NASA’s FIRMS satellite system detected a fire hotspot near the facility. The plant specializes in high-precision optoelectronic, thermal imaging and radar systems, which support Russian weapons and surveillance capabilities.

On occupied Ukrainian territory, Ukraine’s General Staff said Defense Forces struck a Russian ammunition depot in Sievierodonetsk in Luhansk Oblast and a P‑18 Terek radar near Semenivske in Donetsk Oblast on 25–26 September. Footage from the ammunition site showed munitions detonating with multiple secondary explosions. The P‑18 is a mobile two-dimensional VHF radar used to detect and locate aerial targets and feed data to air-defense systems, with a maximum detection range of about 250 kilometers.

Taken together, these hits point to a campaign aimed at Russian depth: fuel hubs on Russian soil, defense plants in the industrial hinterland and key elements of the air-defense network and ammunition storage in occupied areas.

The next indicators will be how quickly Ilsky can resume operations, whether further strikes target other major refineries or defense plants, and whether Russian deployments suggest air-defense assets are being pulled back from the front to shield industrial sites.
