Storm Shadow Strikes Deepen Pressure on Russia’s Defense-Industrial Heartland
Ukrainian long-range missiles have hit a cement plant in Belgorod and two key microelectronics factories in Bryansk and Voronezh that Kyiv says feed Russia’s missile and air defence production. The attacks reach far beyond the front line, aiming at the factories behind the weapons fired at Ukrainian cities. This article unpacks what was struck, why these plants matter to Russia’s arsenal, and how targeting the supply chain could change the tempo of the war.
Ukraine is pushing the war into Russia’s industrial heartland, using long-range missiles to hit factories and plants that sit behind the missiles and drones striking Ukrainian cities. Over recent weeks, and with fresh detail emerging on 23 June, Kyiv has showcased a strategy built not just on stopping incoming fire, but on degrading the defence-industrial network that produces it.
The latest confirmed deep strike targeted a cement factory in the city of Alekseevka in Russia’s Belgorod region. Ukrainian sources say Storm Shadow air-launched cruise missiles were used to hit the site, which has already been struck at least once before. While the facility has reportedly not been in operation for roughly a year, it occupies a location and footprint that can be used for storage, military logistics or future production, and sits within a region that has become a staging ground for Russian operations against Ukraine’s northeast.
More consequential than the Alekseevka hit may be the attacks on Russia’s microelectronics sector that have come into sharper focus. Updated analysis of an earlier strike on the Kremniy EL plant in Bryansk indicates the facility was hit by seven cruise missiles on 10 May, causing significant damage to the main building. Kremniy EL is described as a major supplier of microelectronics for Russia’s defence industry, providing components that can end up in everything from guidance systems to communications gear.
Further south in Voronezh, footage now circulating shows three high-precision missiles striking the VZPP-S semiconductor plant. Ukraine maintains that the plant produces electronic components for some of Russia’s most important weapons: the Iskander-K cruise missile, the Kh-101 air-launched cruise missile, and Pantsir-S1 air defence systems. Those systems have been central to Russia’s bombardment of Ukrainian infrastructure and to defending Russian forces and territory against Ukraine’s growing arsenal of drones and Western-supplied missiles.
By going after the plants themselves, Ukraine aims to stretch Russia’s ability to replenish high-end munitions and sophisticated air defences. Even if Russia can repair facilities or reroute production, such strikes impose costs, delays and a climate of uncertainty for engineers, managers and workers who suddenly find their workplaces on a target list. For ordinary employees in Bryansk or Voronezh, the war is no longer a distant line on a map, but a risk embedded in their commute.
There is also a signalling element. Kyiv’s attacks on defence-industry nodes are happening alongside its daily defence against Russian missiles and drones. Ukrainian officials argue that so long as Moscow continues to hit Ukrainian power plants, ports and city centres, facilities enabling those strikes will be considered fair game, even if they sit hundreds of kilometres from the front.
For Moscow, the challenge is twofold: protect a sprawling industrial base against increasingly capable Ukrainian long-range weapons, and keep output high enough to sustain both offensive operations and a dense air defence umbrella over Russian territory. Russia has been digging in, building protective shelters for strategic bombers at its Engels-2 airbase in Saratov region, and dispersing high-value assets. New satellite imagery from 20 June shows hardened hangars under construction for Tu‑95MS and Tu‑160 aircraft there—physical proof that the Kremlin now expects its long-range aviation sites to be in the crosshairs for years.
The broader consequence is that rear areas across western Russia are being pulled into the war zone. This shift complicates Western debates over what Ukrainian targets should be supported or enabled, but it also raises the cost for Russia of continuing long-range strikes on Ukrainian infrastructure.
The key developments to watch next are whether Ukraine continues to prioritise electronics, fuel and aviation-related plants inside Russia, whether Russia accelerates efforts to relocate or harden sensitive production, and how quickly damaged facilities like Kremniy EL and VZPP-S can restore output. Any sustained disruption to the flow of precision-guided munitions from these factories would eventually show up not in press releases, but in fewer missiles launched at Ukrainian cities.
