President Volodymyr Zelenski publicly confirmed that Ukraine was responsible for the strike on the Kremniy El production complex in Bryansk, carried out using Storm Shadow cruise missiles deployed from Ukrainian aircraft. The announcement ended any ambiguity about the operation's origin and framed it explicitly as a strategic blow to Russia's missile manufacturing capability.

"That factory makes control systems for all types of Russian Federation missiles," Zelenski stated. Kremniy El is a key supplier of semiconductor components used in guidance systems for the Iskander ballistic missile and the Pantsir air defense platform, among other systems. The plant's destruction, Zelenski argued, would meaningfully degrade Russia's ability to sustain high-tempo missile operations against Ukrainian cities and infrastructure. Six people were killed in the strike and 37 others were injured.

Russia announced it would present information about the attack to the United Nations, challenging what it characterized as international silence over civilian casualties caused by Ukrainian long-range strikes. The Bryansk operation forms part of a broader Ukrainian strategy of deep strikes targeting Russian military-industrial supply chains — an approach designed to erode Moscow's capacity to produce and field the weapons it relies on most heavily. Ukraine has increasingly framed such strikes not as escalatory but as a legitimate and necessary dimension of its defensive war effort.
