Russian Military Tech Plant, Major Oil Refinery Hit as 289 Drones Pound Russia Overnight

Russia’s VNIIR-Progress military plant in Cheboksary was reportedly set ablaze following an overnight strike, according to Russian Telegram media channels and videos posted by local residents on social media.

The facility, officially known as JSC VNIIR-Progress, is located in Cheboksary, the capital of Russia’s Chuvash Republic. Photos and videos circulating online appeared to show a large fire and smoke rising from the site after explosions were heard in the area.

Air raid alerts warning of a missile threat were reportedly issued in the region before the explosions occurred.

According to Ukraine’s General Staff, VNIIR-Progress develops electronic warfare (EW) systems, including Kometa antenna arrays designed to interfere with satellite, radar, and radio signals.

The plant also produces satellite GNSS receivers and antennas for GLONASS, GPS, and Galileo. These components – including Kometa-type modules – are integrated into a range of Russian weapons, such as Shahed-type drones, Iskander and Kalibr missile systems, and UMPK guidance kits for aerial bombs, all of which have been widely used in strikes against Ukrainian cities and infrastructure.

Throughout the night, Russian social media reported explosions in the area.  The shopping and entertainment mall MTV Center, located directly opposite the attacked defense plant, was damaged in the attack.

Moscow announced a unilateral Victory Day truce while warning of retaliation if Ukraine attempts to disrupt the May 9 military parade.

Separately, Ukrainian drones carried out a mass attack on Russia’s Leningrad region overnight, governor Alexander Drozdenko said. He reported a fire in an industrial zone in the city of Kirishi, adding that emergency crews had been deployed to contain the blaze.

According to Drozdenko, Russian air defenses shot down 18 drones over the region. No casualties were reported.

Kirishi is home to one of Russia’s largest oil refineries – the Kirishinefteorgsintez (KINEF) plant, owned by Surgutneftegaz.

The facility has processed around 18 million tons of oil annually in recent years, accounting for roughly 7% of Russia’s total refining capacity.

The refinery was previously targeted by drones on March 26 and later resumed operations at reduced capacity.

Russia’s defense ministry said air defenses intercepted and destroyed 289 drones overnight across 18 regions, including Moscow, Leningrad, Tula, Ryazan, Pskov, Novgorod, Tatarstan, and occupied Crimea.

Notably, no interceptions were reported over Chuvashia, where the Cheboksary strike occurred.

Airports across at least 17 cities temporarily suspended operations during the attacks, including in Kazan, Nizhny Novgorod, Samara, Saratov, Perm, Ufa, Pskov, and Cheboksary.
