Ukrainian drones and Neptune cruise missiles targeted the Kamensky factory in Russia's Rostov region overnight on October 31, Ukraine's General Staff reported, in what Kyiv described as a strike on a plant that makes solid rocket propellant for Russian multiple-launch rocket systems.

The plant, in the city of Kamensk-Shakhtinsky, is one of the largest chemical plants in Russia, the General Staff said. It produces solid rocket propellant for the Uragan, Smerch and Tornado-S multiple-launch rocket systems, as well as other missile systems and aircraft weapons, and it has been sanctioned by the European Union, the United Kingdom and the United States for its role in Russia's war against Ukraine.

According to the Ukrainian military, the attack caused a fire at a warehouse storing finished products and damaged four production units. "Strikes on solid rocket propellant production facilities reduce the Russian army's ability to attack Ukrainian settlements with multiple-launch rocket systems," the General Staff said. UNITED24 Media, reporting the same General Staff statement, said the operation involved attack drones and Neptune coastal missile systems operated by the Ukrainian Navy.

Four supply depots also claimed hit

Ukrainian forces also struck four Russian military supply depots, the General Staff said — near Russian-occupied Khartsyzk and Dokuchaievsk in Donetsk region, Novovasylivka in Zaporizhzhia region, and Novoaidar in Luhansk region. Those claims, like the plant strike, come from the Ukrainian military's own reporting.

What Russia has and has not said

The Kyiv Independent said it could not independently verify the reports, and that Russian officials had not commented on the General Staff's statement about the plant. Rostov governor Yury Slyusar did acknowledge a large overnight air attack on his region, saying more than 90 drones were intercepted over the Rostov region overnight, according to Russian reporting carried by breakingthenews.net — an acknowledgement of the scale of the attack, but not a confirmation of damage at Kamensky.

What is solid

  • Ukraine's General Staff publicly claimed the overnight strike on the Kamensky plant and the four depots
  • Rostov's governor acknowledged a large overnight air attack, saying more than 90 drones were intercepted over the region
  • The Kamensky plant makes solid rocket propellant and is sanctioned by the EU, UK and US

What is only claimed

  • The extent of damage at the Kamensky plant and any effect on rocket-propellant production — claimed by Ukraine, not independently established
  • Whether the four supply depots in occupied territory were hit as described

The reported strike fits a pattern Kyiv has followed since the summer: long-range attacks inside Russia and across Russian-occupied territory aimed at oil refineries, military-industrial plants and airfields, intended to degrade Russia's military-industrial capacity. Earlier this week, on October 26, Ukraine reported hitting the Energia plant, described as the sole Russian manufacturer of batteries for glide-bomb guidance and correction modules.

Attribution note

The damage claims in this story are Ukraine's, attributed to its General Staff throughout. Russia has acknowledged a large drone attack on the Rostov region but had not confirmed the Kamensky damage in the reports available at publication.
