Ukraine Drones Blow Up Russian Gunpowder, Microchip Factories

Ukraine's strategic bombing campaign against the assets essential to Russia's military.

The latest targets ranged from the most basic - gunpowder - to the most advanced microelectronics responsible for guiding planes, tanks and missiles. JL

Vera Kravchuk reports in Euromaidan Press:

Ukrainian drones struck the Tambov Gunpowder Factory in Russia’s Tambov Oblast near the city of Kotovsk, 700 km (434 miles) away from the Ukrainian border during the night of 11 June. It manufactures over 200 product types, including gunpowders for small arms, hand grenades, grenade launchers, and artillery shells. Ukraine also struck the microchip and radio-electronics factory in Saint Petersburg essential in the production of Russian bombers, tanks, missiles, guidance systems, vision sights, and radars. Russia confirmed a major fire in the plant responsible for microchip production and assembly. Thick black smoke was seen rising from the facility.

Ukrainian drones struck the Tambov Gunpowder Factory in Russia’s Tambov Oblast during the night of 11 June, marking the latest attack on a facility that supplies explosives to Russian military forces.

Ukraine regularly target Russian military-industrial sites, logistics hubs and oil refineries to degrade Russia’s ability to wage war, disrupt supply chains, and retaliate for attacks on Ukrainian cities.

Acting governor of Tambov oblast Yevgeny Pervyshov confirmed that authorities repelled what he described as a “massive drone attack” on the city of Kotovsk, 700 km (434 miles) away from the Ukrainian border. Pervyshov said law enforcement officers responded to the scene and that “the situation is under control.”

Russian Telegram channels Astra and Mash provided additional details about the incident. Local residents told Astra that the drones targeted the gunpowder factory, which subsequently caught fire. Mash reported that 15 explosions occurred during the attack.

Andrii Kovalenko, head of Ukraine’s Center for Countering Disinformation at the National Security and Defense Council, noted that the facility has been attacked “not for the first time” and indicated that the factory has paused operations following the strike.

The Tambov Gunpowder Factory produces ammunition and gunpowder for small arms, artillery, and rocket systems, as well as colloxilin used in explosives manufacturing. The enterprise manufactures over 200 product types, including pyroxylin gunpowders for small arms, hand grenades, grenade launcher ammunition, and artillery shells.

 

The factory operates as part of the Rostec state corporation and serves as one of Russia’s primary suppliers of explosive materials to its armed forces. Production at the facility increased substantially following the start of the full-scale invasion in Ukraine.

This attack continues a pattern of Ukrainian strikes on the facility. Previous drone attacks occurred in January 2024, July 2024, and November 2023, demonstrating the site’s recurring status as a military target. Ukraine is launching a coordinated campaign across Russia’s military-industrial heartland, to cripple the Kremlin’s ability to wage high-tech war. With a devastating cyberattack on the Tupolev Design Bureau and precision strikes on microelectronics plants, Ukraine is not just targeting weapons, it is forcing Russia’s production capabilities back to the stone age.

The Ukrainian Operation Spiderweb inflicted significant losses on Russia, with 25 strategic aircraft confirmed damaged or destroyed. Notably, Russian authorities are already trying to hide the extent of the damage by swapping out destroyed bombers for intact ones taken from airfields not hit by the strikes.

To complement the severe blow against the Russian strategic bomber aviation, the Ukrainian Military Intelligence conducted an extensive cyberattack on the Tupolev Design Bureau, which designs and produces all Russian strategic bombers. Ukrainian intelligence gained access to more than 4 gigabytes of sensitive data. The leaked files include internal correspondence between company executives, personal data of employees, home addresses, biographies of engineers and designers, procurement documents, and classified disclosures from closed-door meetings.

The breach provides Ukrainians with comprehensive insight into operations and personnel involved in maintaining Russia’s strategic aviation fleet. This information could be used for the sabotage of the plant through low-ranking aviation engineers who can be recruited into Ukrainian information networks, with humans always being the weakest link in such large-scale organizations. 

Additionally, to cement the inability of Russians to rebuild their strategic bomber fleet, the Ukrainians decided to strike factories that produced other high-tech components necessary for the Russian war effort. These factories produce various microchips and technology essential in the production of Russian bombers, tanks, missiles, guidance systems, vision sights, and radars.

The Ukrainians most recently struck the Avangard microchip and radio-electronics factory in Saint Petersburg. While Russian media initially claimed that all Ukrainian drones were intercepted, Russian emergency services confirmed a major fire in the section of the plant responsible for microchip production and assembly. Thick black smoke was seen rising from the facility, with the blaze covering around 100 square meters.

Before that, Ukrainian drones targeted the Bolkhov Semiconductor Device Plant, scoring multiple direct hits on the main building. The explosions triggered extensive fires that spread across the facility, causing significant damage and putting the factory out of commission.

Earlier, the Strela microelectronics plant in the town of Suzemka, Bryansk region, was struck. Located just 8 kilometers from the Ukrainian border, it was within range of HIMARS strikes, which caused the most extensive damage of all the targeted Russian military-industrial plants. Satellite imagery later confirmed that nearly the entire facility was destroyed, leaving no operational production capacity.

Finally, the Ukrainians hit the Kremniy El microelectronics plant in the city of Bryansk, delivering multiple strikes that ignited a large fire throughout the site. This was the fifth attack on the plant since the start of the war, but the latest damage appears to be the most devastating yet.

The Ukrainian strikes had a major impact, targeting key sites in Russia’s military-industrial complex. The Avangard plant, where a massive fire broke out, produces radio electronics, microchips, and communication systems used in ballistic and cruise missiles, with even Russian authorities listing it as one of the most strategically important facilities.

The strike on the Bolkhov plant was even more severe, disrupting the production of critical components for Sukhoi fighter jets, Iskander ballistic missiles, and Kinzhal hypersonic missiles. The Strela plant in Suzemka, which produces microchips for systems like the Tor air defense platform, was entirely reduced to rubble and must be rebuilt from the ground up.

Meanwhile, the Kremniy El plant in Bryansk, one of Russia’s largest microelectronics producers, supplied parts for Pantsir systems and Iskander missiles. These strikes severely limit Russia’s ability to produce advanced weaponry, forcing a shift to lower-tech solutions that reduce combat effectiveness and increase frontline losses.

Overall, the Ukrainians conducted some of the most devastating strikes on the Russian military industry in recent months. With over thirty percent of Russia’s nuclear-capable strategic bombers destroyed, Ukrainians are now starting to dismantle their ability to build these weapons entirely. The breach of the Tupolev Design Bureau internal systems means now Ukraine possesses Russia’s most sensitive data on its strategic bombers designs and still active aircraft fuelling future precision strikes and combat operations that place the remaining Russian fleet at serious and growing risk.
