Defense Express reported that the strike hit the russian enterprise AO VNIIR-Progress, located roughly 1,000 km from Ukraine’s border, and said the plant manufactures anti-jamming Kometa satellite navigation antennas.

Defense Express also said that, according to available data, approximately five missiles were used in the strike, and that two Flamingo missiles were intercepted on their approach to the Chuvash region while another was reportedly shot down near Cheboksary itself.

The BBC added that Zelensky wrote on Telegram that "Overnight, Ukrainian FP-5 Flamingos hit a military plant in Cheboksary that supplies the occupier’s army with components for drones and missiles" and that Ukraine’s military later said the VNIIR-Progress plant had been struck with a fire at the site.

Zelensky told X, "We continue to apply Ukrainian long-range sanctions against Russian military facilities and the oil industry," and said the Flamingo strike in Cheboksary supplied the occupier’s army with components for drones and missiles.

Ukrinform likewise quoted Zelensky thanking the Armed Forces of Ukraine for precision and saying, "I thank the Armed Forces of Ukraine for their precision!"

Defense Express

Defense Express described a publicly circulated flight-path visualization of the Flamingo missiles during the attack on the facility in Cheboksary, saying it was produced using open-source data including reports from russian Telegram channels and processed with the OCHI AI system.

The same Defense Express analysis said active maneuvering was observed during the initial phase of flight and on the final approach, and that the visualization indicates the missiles bypassed the city at a distance of roughly 170 km before turning back toward the target area.

In parallel, the OSINT work cited by Мілітарний concluded that the VNIIR-Progress plant’s production facilities were likely struck by two FP-5 Flamingo cruise missiles, with analysts estimating about five missiles were involved in the attack and that two were shot down while approaching Chuvashia.

The Cheboksary attack was part of a broader Ukrainian assault that also struck the Kuibyshev oil refinery in Russia’s Samara Oblast, more than 900 kilometers from the front line, and two oil infrastructure facilities in Russia’s Vladimir Oblast, 700 kilometers away, according to Zelensky.

“Main characteristics: it has a range of up to 3,000 kilometers, can carry explosive payloads of 1,150 kilograms, is relatively accurate, up to 210 units can be produced per month, and it costs less than its Western 'primes' missiles”

The Kyiv Independent said Zelensky also described Ukraine’s Security Service (SBU) Alpha special forces units striking the Vtorovo and Lobkovo oil pumping stations in Russia’s Vladimir Oblast, and that local authorities reported fires at two infrastructure facilities after the attack.

The BBC reported that Russia’s air defenses intercepted or shot down 326 Ukrainian drones over a number of regions overnight, while Ukraine’s air force said it downed 181 out of 207 drones fired by Russia during that time.

Euronews said the Kuibyshev oil refinery processes around 3.7 million tonnes of oil annually and supplies fuel products used by Russia’s military-industrial sector and armed forces, tying the strikes to targets Kyiv says support Moscow’s war effort.

Defense Express framed the Cheboksary outcome as successful, noting that since the facility was hit the overall outcome can be considered successful, while also emphasizing that interceptions remain possible even with detailed mission planning and intelligence support.
