A Ukrainian cruise missile FP-5 Flamingo struck this morning the Russian defense plant JSC VNIIR-Progress, located in Cheboksary, the capital of the Chuvash Republic, over 900 kilometers from the Ukrainian border, in one of the deepest attacks carried out by Kiev since the beginning of the war.
The camera of a Russian user's mobile phone captured the flight and explosion of the Flamingo missile over the facility, and videos quickly circulated on social media.
On his social media, former Ukrainian official Anton Gerashchenko confirmed that the attack destroyed part of the plant, which produces Kometa navigation modules used in drones, cruise missiles, and Russian ballistic missiles, including the Shahed and Iskander that Moscow employs against Ukraine.
The attack with Flamingo was followed by at least four Liutyi attack drones during the morning of the same day. Analysts noted that if the missile struck the building directly, "that section of the floor simply no longer exists."
The anti-drone cages installed by Russia at the facility proved completely ineffective against the cruise missile, according to reports from the portal Defence-UA regarding Russian defenses in Cheboksary. An adjacent shopping center suffered collateral damage, and a drone struck a nearby residential building, with at least one injury reported by local authorities.
The FP-5 Flamingo was developed by the Ukrainian company Fire Point, publicly unveiled on August 18, 2025, and delivered to the Ukrainian Armed Forces in December of that year.
With a declared range of 3,000 kilometers—approximately double that of the Tomahawk Block V—and a warhead weighing up to 1,150 kilograms, it marks the most significant leap in Ukraine's long-range strike strategy. Its serial production reaches 210 units per month.
The president Volodimir Zelensky had already praised the potential of the system after a previous attack: “We carry out precise attacks with Flamingo missiles at a range of 1,400 kilometers. I believe this is truly a success for our industry,” he declared in February 2026 after striking the Votkinsk complex, a producer of Russian ballistic missiles.
The attack on Cheboksary is part of a broader Ukrainian campaign that is changing the dynamics of the conflict and increasingly involves technological innovations in the arms industry.
According to the Institute for the Study of War in its assessment from May 2, for the first time since August 2024, Russia experienced a net loss of territory in April 2026: it lost 116 km² compared to just 28.28 km² gained, a reversal of 4.1 to one against Moscow.
Meanwhile, the drone campaign against Russian oil infrastructure has dealt a severe blow to the Kremlin's war economy.
In March 2026, Ukraine launched over 7,000 long-range drone systems, and Russian oil exports fell by 43% in just one week, with estimated losses of $1 billion. The output of Russian refineries in April was the lowest since late 2009.
The VNIIR-Progress plant had already been attacked by Ukrainian drones in June, July, and November 2025, and in February 2026, but none of those attacks matched the destructive power of the Flamingo.
The large-scale Russian invasion began on February 24, 2022 and since then, Ukraine has focused on developing its own weaponry due to Western restrictions on using their arms in Russian territory.
An economic analysis center linked to the Kremlin itself warned that "Russia's economic growth could slow down much more than expected in 2026, because repeated attacks on ports and refineries are undermining Russia's ability to export crude oil and fuel," a sign of the growing fear in Moscow regarding Ukraine's determination to win the war.
