Defense Express reported the information.Ukraine's General Staff confirmed an effective strike on one of Russia's most critical military-industrial facilities—the Federal State Enterprise Sverdlov Plant—located near Dzerzhinsk in the Nizhny Novgorod region, approximately 750 kilometers from the Ukrainian border. The attack, which took place on the night of October 6, resulted in multiple explosions and fires at the facility, according to official reports and footage captured by local residents.The Sverdlov Plant represents what military analysts consider a top-priority target in Russia's defense infrastructure. As Russia's largest producer of explosive materials, the facility is reportedly the country's only industrial-scale manufacturer of octogen and hexogen—two critical compounds used in virtually all Russian munitions, from standard artillery rounds to advanced ballistic missiles. The plant directly supplies nearby facilities, including the 53 Arsenal located just 4 kilometers away, which assembles aviation bombs including the FAB-3000 and various artillery shells.Ukrainian forces managed to penetrate the plant's substantial air defense systems using long-range drones, despite the facility's robust protective measures. Prior to this strike, Ukraine had already successfully attacked the Sibur-Kstovo oil refinery, a key raw material supplier to the Sverdlov Plant, but this marks the first direct hit on the explosives production facility itself.The plant, originally established in 1916 and significantly expanded during the Soviet era, was specifically designed to withstand attacks. Its production and logistics operations are deliberately dispersed and protected by earthen barriers to prevent catastrophic chain reactions. This architectural reality means that effectively degrading the facility's capabilities requires not just appropriate weaponry—and long-range drones with their relatively small warheads are far from ideal—but sustained, methodical strikes over time.The successful attack represents a significant disruption to Russia's ammunition supply chain at a time when Moscow's forces are expending vast quantities of ordnance in their ongoing military operations.Ukrainian forces struck key Russian military-industrial and logistical targets overnight on October 6, including one of Russia’s largest explosives manufacturers, the Sverdlov Plant, and an oil transshipment terminal in occupied Crimea.
