According to the Belarus Investigation Center (BIC), the value of military equipment and components supplied by Belarusian businesses to the Russian defense industry has increased sharply since the conflict in Ukraine broke out.
Data collected from 58 Belarusian companies shows that the value of military goods exported to Russia in 2024 has doubled compared to 2022 - the time Russia launched a large-scale military campaign in Ukraine.
According to BIC, from February 2022 to August 2025, Belarusian businesses have transferred at least 1.2 billion USD of components and equipment to Russia. These items include optical systems, missile launchers and heavy wheeled chassis for the production of military equipment.
The products are supplied to 41 Russian defense factories, including many facilities that both produce civilian goods and military equipment.
Ukrainian military intelligence assesses that Russia is currently significantly dependent on Belarus in many key areas. It is estimated that Belarus provides up to 85% of military optoelectronic systems and scopes, about 90% of wheeled chassis for missile systems and about 80% of ammunition transportation and launch systems.
Notably, only more than half of the Belarusese businesses on the list have been sanctioned by the West. Nearly half of the rest are still operating normally in the international market.
The enterprise with the largest export value is Peleng company, specializing in manufacturing optoelectronic equipment. According to investigation data, Peleng exported about 875 million USD of goods to Russia, including aiming systems and fire control equipment for tanks.
Ukrainian military intelligence confirmed that many Peleng products have been detected on Russian tanks and armored vehicles seized during the war.
Another major supplier is the Minsk Wheel Tractor Factory, a unit specializing in producing chassis for Russian heavy-lift missile and equipment complexes.
The report also shows that from 2022 to mid-2025, Belarusian companies received about 800,000 USD of goods of Western origin through Russia. The shipments included US microchips, German electrical equipment, Swiss components and many other technology products. Some goods were transshipped through Hong Kong (China), Thailand and India before reaching Belarus.
Experts believe that loopholes in the international sanctions mechanism are helping some businesses continue to participate in the supply chain serving the Russian defense industry.
