Ukrainian Flamingo cruise missiles and AN-196 Liutyi drones struck the production facilities of the VNIIR-Progress defense plant in the Russian city of Cheboksary, located about 1,000 km from the Ukrainian border.
The corresponding images were published by CyberBoroshno.
Analysis shows that an FP-5 Flamingo cruise missile struck the front of the main building at an angle. The building was protected by anti-drone nets, indicating its priority status among the plant’s facilities.
The Telegram channel Exilenova+ released a video of the main building, showing damage to the facade and the interior.
A massive fire broke out inside and around the building. Shortly after the strike, a construction crane was observed operating near the building, likely to dismantle damaged structures or clear debris.
Separately, two AN-196 Liutyi drones struck another company building, which also caused a fire.
The strike was carried out on the night of May 5. Ukrainian President Volodymyr Zelensky confirmed the use of Flamingo missiles.
The missiles were launched by units of the 19th Saint Barbara Separate Missile Brigade, which was previously armed with tactical ballistic missiles from the Tochka-U system.
VNIIR-Progress
The plant is located in Russia’s Chuvash Republic, about 1,000 km from the Ukrainian border, and is part of the ABS Elektro production association.
The enterprise specializes in the production of GNSS receivers and antennas for the GLONASS, GPS, and Galileo satellite systems. Specifically, this includes Kometa-type modules, which are widely used in unmanned systems, including Shahed-type kamikaze drones, as well as in missile systems — the Iskander-M and Kalibr systems and UMPC guidance kits for aerial bombs.
In addition, VNIIR-Progress manufactures electrical equipment, including circuit breakers, relays, and contactless modules, which are supplied to the Russian Navy, including the Yasen-M-class nuclear submarines.
The facility has repeatedly been targeted by Ukrainian long-range strike drones.
In particular, on February 18, 2025, a fire broke out at the facility following one of the strikes. After the attack on June 9 of last year, the plant temporarily suspended operations. The facility subsequently came under attack again on July 5 and November 26, 2025.
