Drones may have hit Voronezhsintezkauchuk plant in Voronezh

"The business is located near a combined heat and power plant. Less than 2 kilometers away, a Pantsir air defense missile-gun system is deployed on elevated ground. An S-300/S-400 air

defense system position is also believed to be nearby.
Voronezh Oblast Governor Oleksandr Gusev said Russian air defenses allegedly destroyed 88 drones over Voronezh and at least six districts of the oblast overnight.
Voronezhsintezkauchuk is a Russian business that produces synthetic rubber and thermoplastic elastomers. Overnight drones attacked Russia’s Ulyanovsk, where OSINT analysts reported that the Iskra Plant, a research and production business, was hit. The business is part of the Almaz-Antey concern and produces components for military equipment, including Kh-59M2/M2A guided missiles." msn
