A fire broke out at what is reportedly the Progress defense plant in Cheboksary, Russia, following a missile strike on 10 June, the governor of Russia's Chuvash Republic said, according to Russian telgram channel Astra.

The incident marks the second reported strike on the same facility in under a week — on 5 May, Ukrainian FP-5 Flamingo missiles were reported to have struck the VNІIR-Progress defense enterprise in the same city, with President Volodymyr Zelenskyy confirming the attack.

Oleg Nikolaev, governor of Chuvash Republic, confirmed on Telegram that Cheboksary had come under missile attack. He did not specify casualties or damage.

What the strike targeted

Photos and video of a fire following the strike in Cheboksary were published by Russian social media channels, including footage of a missile passing over the city. According to OSINT analysis by Astra, the targeted facility is the VNIIR-Progress defense enterprise.

The plant manufactures Kometa antennas — systems designed to protect drones from electronic warfare — as well as other components used in Russian Shahed drones and Iskander-M and Kalibr missiles.

Astra analysts also noted that the VNIIR-Progress premises had been fully covered with camouflage netting following the previous strike.

The weapon used

Monitoring channel Exilenova+ identified the missiles used as Ukrainian FP-5 Flamingo cruise missiles. Denis Shtilerman, founder of the Ukrainian company FirePoint, which produces the Flamingo, published a photo of a launch on X on 10 June, without providing further details.

Previous strike

The 5 May attack on the same plant caused a large-scale fire after a missile struck the facade of one of the factory buildings, according to OSINT analysts. Zelensky confirmed the use of Flamingo missiles in that incident.
