Satellite imagery shows damage at VNIIR-Progress, a Russian defense plant in Cheboksary, according to the OSINT project CyberBoroshno. The plant supplies navigation antennas for Russia's Shahed drones, Iskander missiles, and glide bombs. Ukraine's overnight strike combined Flamingo cruise missiles and Liutyi drones, breaching anti-drone netting installed over the main building.
How the strike unfolded
The FP-5 Flamingo cruise missile hit the front of VNIIR-Progress's main building at an angle, Militarnyi reported. Russia had wrapped the building in anti-drone netting — a sign it treated the workshop as a priority target. A massive fire broke out inside and around the structure. Two AN-196 Liutyi drones then hit a second building at the plant, which also caught fire. A construction crane was operating beside the main workshop, likely to clear damaged structures and debris.
Ukrainian Telegram channel Exilenova+ posted a video of the torn-open facade and burned-out interior. Telegram channel Dnipro Osint Harbuz also shared footage of the facade after the impact.
Ukrainian drones already hit VNIIR-Progress four times in 2025: on 18 February, 9 June, 5 July, and 26 November. The same night, Ukrainian drones also struck the Kirishi oil refinery in Russia's Leningrad Oblast.
