Chinese-made engines are being covertly shipped via front companies to a state-owned drone manufacturer in Russia, labelled as "industrial refrigeration units" to avoid detection in the wake of Western sanctions, according to three European security officials and documents reviewed by Reuters.

The shipments have allowed Russian weapons-maker IEMZ Kupol to increase its production of the Garpiya-A1 attack drone, despite the US and EU sanctions imposed in October designed to disrupt its supply chain, according to the sources and documents, which included contracts, invoices and customs paperwork.

An internal Kupol document, reviewed by Reuters, showed it signed a contract with the Russian defence ministry to produce more than 6,000 Garpiya this year, up from 2,000 in 2024. The document stated that more than 1,500 drones had already been delivered by April.

The long-range drone is being deployed to attack civilian and military targets deep within Ukrainian territory, with around 500 being used by Russia per month, the Ukrainian military intelligence agency said in a statement to Reuters. The European security officials asked that neither they nor their organisation be identified due to the sensitivity of the information. They also requested some specific details in the documents be withheld, such as their dates and the cost of contracts.
