Belarus expands critical arms supply network to Russia despite sanctions loopholes

Belarus has emerged as one of Russia’s most important military-industrial lifelines as Moscow struggles to sustain its war effort in Ukraine under sweeping Western sanctions. Newly examined trade data shows that Belarusian companies dramatically increased shipments of military-related hardware and components to Russian defense manufacturers between 2022 and 2025, while nearly half of the identified suppliers continue operating without Western sanctions.

The data, obtained by the Belarusian Investigative Center (BIC), paints a detailed picture of how Belarus has become deeply integrated into Russia’s wartime supply chain. According to the records, 58 Belarusian companies exported at least $1.2 billion worth of military-related equipment and components to Russian defense enterprises from February 2022 through August 2025. The value of those exports doubled in 2024 compared to the first year of Russia’s full-scale invasion of Ukraine.

The shipments included advanced optics, missile-launching systems, heavy wheeled chassis, transport-loading equipment, thermal imaging devices, and electronic components destined for at least 41 Russian defense plants. Many of those factories produce tanks, artillery systems, missiles, armored vehicles, and air-defense platforms that are actively used in the war in Ukraine.

The findings highlight how Belarus has become indispensable to Russia’s military production at a time when Western sanctions and export controls have restricted Moscow’s access to advanced technology and industrial components. Ukrainian military intelligence estimates that Russia remains heavily dependent on Belarusian industry in several key military sectors.

According to those assessments, Russia relies on Belarus for up to 85 percent of its optoelectronic systems and sights, as much as 90 percent of wheeled chassis used in missile systems and heavy military equipment, and roughly 80 percent of transport-launching and loading systems.

The scale of that dependency underscores the strategic importance of Belarusian defense manufacturers to the Kremlin’s war machine.

One of the most significant suppliers identified in the data is JSC Peleng, a Belarusian state-linked producer specializing in optoelectronic systems. Peleng alone reportedly shipped approximately $875 million worth of equipment and components to Russian customers during the examined period.

Among its largest deliveries were $362 million worth of products sent to the Vologda Optical and Mechanical Plant, a Russian enterprise that manufactures targeting and sighting systems for tanks and armored vehicles. Peleng also shipped around $281 million worth of targeting equipment to Uralvagonzavod, Russia’s largest tank manufacturer and producer of the T-72 and T-90 battle tanks.

Ukrainian military intelligence officials confirmed that Peleng-made systems have been discovered inside captured Russian armored vehicles on the battlefield. These reportedly included fire-control systems, thermal imaging sights, and targeting technology integrated into tanks and armored personnel carriers deployed in Ukraine.

Another key contributor to the Russian military supply chain is the Minsk Wheeled Tractor Plant, known for manufacturing heavy-duty chassis used in missile launchers and strategic military systems. Trade data shows that the company supplied at least 91 chassis valued at more than $30 million to Motovilikhinskiye Zavody, a Russian producer of artillery systems and military equipment.

The Belarusian manufacturer also reportedly delivered nearly $52 million worth of components to Titan-Barrikady, a Russian company producing self-propelled missile launchers, along with another $44 million in equipment to NZ 70 Letiya Pobedy, which manufactures components for Russian air-defense systems.

Military analysts say Russia’s dependence on Belarusian chassis is particularly significant because such systems are difficult to replace quickly through domestic production. Modern missile launchers and mobile air-defense systems require specialized heavy wheeled platforms capable of carrying large loads across difficult terrain.

Andrii Kharuk, a Ukrainian military historian and professor at the Hetman Petro Sahaidachnyi National Army Academy, said Russia’s own industrial base has struggled to keep pace with wartime demand. Battlefield losses, combined with sanctions-related shortages, have increased Moscow’s reliance on Belarusian suppliers.

According to Kharuk, Belarus continues to play a crucial role in supplying thermal imaging systems and heavy chassis because Russian manufacturers are unable to produce sufficient quantities domestically.

A third major Belarusian supplier identified in the records is OKB TSP, a company specializing in weapons systems, military software, and control hardware. Export data indicates that OKB TSP shipped approximately $62 million worth of transport-launching and loading systems to NPO Mashinostroyeniya, a Russian missile producer known for manufacturing cruise missiles and other strategic weapons.

While the three largest Belarusian suppliers are already under Western sanctions, investigators found that many smaller companies involved in military exports remain untouched by international restrictions. Of the 58 companies examined, only slightly more than half are currently sanctioned by Western governments.

Among the unsanctioned firms is Brake Hydraulics, a Belarusian subsidiary of a British company that allegedly supplied parts to a Russian armored personnel carrier manufacturer. The existence of such companies illustrates what sanctions experts describe as major enforcement gaps within the Western sanctions regime.

Pavlo Shkurenko, a sanctions researcher at the Kyiv School of Economics, said several factors contribute to delays in blacklisting companies tied to Russia’s military supply chain. These include lengthy legal procedures, disagreements among European Union member states, and inconsistent political willingness to impose additional restrictions.

Shkurenko argued that documented shipments to Russian defense enterprises should be sufficient grounds for sanctions designations. He noted that although sanctions implementation remains imperfect, restrictions still increase costs and create shortages for both Russian and Belarusian military industries.

According to him, the pressure generated by sanctions forces Russian industry to redirect limited resources toward military production, weakening civilian sectors and creating broader economic strain.

The investigation also revealed another troubling dimension of the Belarus-Russia defense partnership: the continued flow of Western-origin technology into Belarusian industry through indirect supply routes.

Trade records reviewed by BIC indicate that Belarusian companies received approximately $800,000 worth of Western-made goods routed through Russia between April 2022 and July 2025. These products reportedly included German electrical and chemical analysis instruments, Swiss motors and electronic components, British integrated circuits, American microchips, and Italian semiconductor manufacturing equipment.

To obscure the true destination of the goods, intermediaries allegedly routed some shipments through companies located in Hong Kong, China, Thailand, and India before they eventually entered Russia and crossed into Belarus.

The findings highlight the ongoing challenge facing Western governments attempting to isolate Russia’s military-industrial complex. Despite multiple rounds of sanctions, Russian and Belarusian defense manufacturers continue finding alternative procurement channels for critical technologies and industrial equipment.

The Belarusian government and its defense authorities did not publicly comment on the allegations. According to BIC, requests for comment were sent to all identified Belarusian and Russian companies, as well as Belarus’ State Authority for Military Industry, but no responses were received.

The growing military-industrial integration between Moscow and Minsk has become one of the defining features of the regional security landscape since the start of the war in Ukraine. Belarus has already allowed Russian forces to use its territory for military operations, logistics, and training. Now, the latest trade data suggests that Belarusian industry is also playing a central role in helping Russia replenish weapons systems and sustain long-term military production.

As the war drags on and sanctions pressure intensifies, analysts expect Russia’s reliance on Belarusian suppliers to deepen further. The continued operation of unsanctioned companies, combined with the successful rerouting of Western technologies through third countries, suggests that major gaps remain in the international effort to disrupt the Kremlin’s wartime supply chains.
