The Perm Refinery Drone Strike: 592 Drones, a Urals Giant Burning, and the Plant That Feeds the Kh-59

Russia's Defense Ministry says it intercepted 592 Ukrainian drones overnight into September 25, across its regions, occupied Crimea, and the Black Sea. That claim, reported by Meduza, sits just under the 629 Moscow claimed a week ago, and it did not stop the night's headline event: the Perm refinery drone strike, a hit on the Lukoil-Permnefteorgsintez complex in the Urals, roughly 1,500 kilometers from the Ukrainian border per the Kyiv Independent. By morning, five Russian regions were reporting hits on industrial plants, southern Russia's only refinery had shut down, and a semiconductor plant that feeds Kh-59 missiles and Pantsir air defense vehicles had taken a direct hit on camera.

Inside the Perm Refinery Drone Strike

Lukoil-Permnefteorgsintez is not a border-belt target. The complex processes more than 13 million tons of crude a year, which puts it among Russia's ten largest refineries per Kyiv Post, and it anchors fuel supply across the Urals industrial belt. Overnight, eyewitness video and OSINT accounts showed fire and black smoke over the plant, and Kyiv Post reports preliminary indications that the AVT-5 crude distillation unit was hit. Perm Governor Dmitry Makhonin confirmed what he called a massive UAV attack on an industrial facility. His first statement said no casualties; Meduza later reported one person killed in Perm Krai during the attack.

This is the second time drones have reached the plant in about a month. United24 Media notes an August strike that reportedly damaged a primary atmospheric-vacuum distillation unit, the front end of the refining process. Repeat visits at this depth are the tell: this was not a lucky leaker through air defense, it is a target set being worked methodically at a range that most of Russia's refining map once treated as safe.

Iskra in Ulyanovsk: The Chips Behind the Kh-59 and the Pantsir

The night's most interesting target was not a refinery at all. In Ulyanovsk, on the Volga, drones struck the Iskra plant, part of the Almaz-Antey aerospace and defense concern. Militarnyi reports the facility is involved in production of Kh-59M2 guided air-launched missiles and turns out the quiet plumbing of Russia's war electronics: transistors, Schottky diodes, optocouplers, and IGBT power modules, including components used in Pantsir-S1 combat vehicles. The Russian outlet ASTRA confirmed the strike location through open-source analysis, and video showed a drone diving into the plant followed by an explosion.

Governor Alexei Russkikh said eight people were injured, including a child, and that both industrial and civilian infrastructure were damaged. The channel has tracked Ukraine's component-hunting campaign all year, from the ferrocene supplier in Volgograd to the Kh-101 ledger, and Iskra fits the same doctrine: if you cannot intercept every missile, go after the fabrication lines that fill its guidance and power sections. Almaz-Antey is also the concern expanding Shahed-type drone production, including a new plant in Izhevsk, per Militarnyi, which makes its electronics subsidiaries a rational standing target.

Novoshakhtinsk Halts, and the Rocket Fuel Chain Takes Two Hits

Closer to the border, the sweep was broader. In Rostov Oblast, the Novoshakhtinsk oil products plant, the region's only refinery at 5.6 million tons a year and, per Ukrinform, the largest petroleum products supplier in southern Russia, took damage and suspended operations. Governor Yuri Slyusar said around 50 drones were intercepted over the region. The same night, per Ukraine's General Staff via ArmyInform, strike packages destroyed two air defense radars near Novoshakhtinsk: a Gamma-S1 and a low-altitude Kasta-2E2, the kind of eyes that are supposed to stop nights like this one.

The propellant chain took its own double tap. The General Staff says drones hit the Voronezhsintezkauchuk plant near Voronezh and the Yefremov synthetic rubber plant in Tula Oblast, and states both are involved in producing solid rocket fuel components, including for Iskander ballistic missiles. Governor Alexander Gusev claimed 88 drones downed over Voronezh; Meduza reports 13 injured there, including a child, plus damaged apartment facades and vehicles.

Russia's answer ran on the same clock. Ukraine's Air Force says Moscow launched 295 strike drones overnight, including jet-powered types, from Oryol, Kursk, Millerovo, Primorsko-Akhtarsk, occupied Donetsk, and Crimea; 267 were shot down or suppressed, with hits recorded at 16 locations. In Kyiv, a drone struck a commercial building in Podilskyi district and debris damaged residential blocks; Mayor Vitali Klitschko reported one person injured.

Why It Matters

Both of these campaigns are now negotiating positions. Three days ago Zelensky told Trump at the UN that Kyiv is ready for any kind of format of energy ceasefire, on reciprocal terms, per the Kyiv Independent. The Perm night is what those terms look like priced in drones: Ukraine's refinery campaign has disrupted roughly a third of Russian refining and pushed crude runs to decade lows per United24 Media, while Ukraine's General Staff put the disabled share at 45 percent earlier this week. Every deep strike between now and any signature raises the cost of Moscow's preferred alternative, which is a winter energy campaign Russia has already pre-announced.

The depth matters as much as the tonnage. A 1,500 kilometer reach, demonstrated twice against the same Urals refinery in a month, collapses the idea of a rear area. And the Iskra and rubber-plant hits extend the target set from fuel revenue to missile production itself, the same logic the channel traced in the Volgograd ferrocene strike: fewer working component and propellant lines now means fewer Kh-59s and fewer interceptor-hungry Iskander salvos later.

What to Watch

The diplomacy has a timer on it. Zelensky said Friday that Washington has proposed a technical-level trilateral meeting with Russia, with the UAE floated as the venue, and framed the horizon himself: return in 10 days with either a new perspective or a result, per the Moscow Times. The Kremlin says a meeting could happen soon. Behind that, Ukraine and Taiwan are on the agenda for the Trump-Xi summit in Washington, and Trump has invited Putin to the Miami G20 in December per Secretary of State Rubio. Watch whether Novoshakhtinsk restarts, whether Lukoil discloses damage at Perm, and whether the pre-announced Russian energy campaign opens before or after the UAE table is set.
