Ukrainian strike drones attacked a chemical plant in Russia’s Ivanovo Oblast that supplies products for missile engine production, according to reports from the Astra news resource.

At least two strike drones hit a supply warehouse at the Dmitrievsky Chemical Plant, Astra reported on 26 May.

Local residents reported loud rumbling and unusual sounds in the sky during the attack. The Ivanovo oblast’s operational headquarters said that drone debris was found at the enterprise’s industrial zone.

The plant is located approximately 800 kilometers from Ukraine’s state border. Ukraine’s military has not commented on the attack yet.

The facility reportedly is one of Russia’s largest producers of chemical and petrochemical products for civilian markets. However, the plant also participates in supplying Russia’s defense industrial complex.

The enterprise primarily supplies its products to the Kazan State Gunpowder Plant, a defense facility located in Kazan, Tatarstan Republic. This plant specializes in manufacturing gunpowder, explosives, and related products for both military and civilian needs.

According to open data, the Dmitrievsky Chemical Plant has 14 contracts worth about 52, 000 000 rubles (over $652,000). These contracts involve selling chemicals necessary for producing gunpowder and explosives, mainly for defense needs.

The plant also supplies products to the Kamensky Combine. These shipments include industrial explosives such as TNT, RDX, and HMX. The facility also provides chemical components for ammunition, polymers, and special dual-use chemical substances. This contract is valued at about 50,000 000 rubles (over $627,000).

Ukrainian Defense Forces previously struck the same plant in December 2024.

Earlier reports indicated that Ukrainian strike drones hit the Azot chemical enterprise in Novomoskovsk, Tula Oblast. The Azot chemical complex in Novomoskovsk is one of Russia’s largest chemical industry enterprises. The facility specializes in producing nitrogen fertilizers, including ammonia, urea, and other chemical products.

China is providing machine tools, special chemicals, gunpowder and components directly to Russian military enterprises, according to Ukraine’s Foreign Intelligence Service.

Oleg Ivashchenko, head of Ukraine’s Foreign Intelligence Service, said that China supplies machine tools, special chemicals, gunpowder and components specifically for military enterprises to 20 Russian factories.

The intelligence chief said his agency documented at least five instances of aviation cooperation with China during 2024-2025. These cases involved equipment, spare parts and documentation. Six separate incidents involved large deliveries of special chemicals.

Chinese components dominate Russian drone production. Ivashchenko reported that 80% of critical electronics for Russian drones had Chinese origins at the start of this year.

“There are substitutions, deception in names, shell companies through which everything necessary for microelectronics production goes from China to Russia,” Ivashchenko said.

The intelligence revelations support earlier claims by Ukrainian President Volodymyr Zelenskyy. In April, Zelenskyy said Ukrainian intelligence services obtained evidence of China-Russia cooperation in weapons supplies.

“Under Chinese weapons in Russia, I mean gunpowder and artillery,” Zelenskyy said at the time. He added that China was helping manufacture weapons inside Russia itself.

Chinese officials have denied providing weapons to either side in the war. Foreign Ministry spokesman Lin Jian said China “not only does not provide lethal weapons to any party, but also strictly controls dual-use goods” that could be used for weapons production.

Zelenskyy responded by adding several Chinese companies to Ukraine’s sanctions list. These companies were involved in production of Iskander missiles, according to the Ukrainian president.
