Ukrainian drones struck the Dorogobuzh plant in Russia's Smolensk region on February 26, 2026, causing extensive damage that renders the facility beyond restoration, according to CyberBoroshno and Exilenova+ reports between 12:16 PM and 1:45 PM UTC. Exilenova+ stated the plant is "totally fucked" with images forthcoming, while CyberBoroshno declared "Dorogobuzh is fucked," attributing the destruction during this 1-hour-29-minute window to drone attacks. No official Russian confirmation was reported in the sources. This strike follows earlier Ukrainian-Baltic defense partnerships announced around 11:16 AM to 12:15 PM UTC by Roboneers with SUBmerge Baltic and NRC for underwater technologies, as reported by Оборонка, and a Russia-Ukraine prisoner exchange at approximately 11:00 AM UTC involving 35 bodies to Russia and 1,000 defenders to Ukraine, per Supernova+.
