Ukrainian intelligence has revealed that North Korea has deployed a 400-person drone unit among 8,500 newly arrived troops in Russia’s Kursk Oblast, marking a significant escalation in Pyongyang’s military support for Moscow’s war in Ukraine. Major General Vadym Skibitskyi, deputy head of Ukraine’s Main Military Intelligence Directorate (GUR), reported the deployment on August 21, describing it as a major development in North Korean battlefield capabilities.
Skibitskyi told reporters that the North Korean drone operators could survey and strike targets within Ukraine from positions in Kursk, gaining critical experience in modern unmanned warfare. The 400-strong drone unit represents a qualitative shift in North Korean involvement, moving beyond infantry to specialized technical roles.
“The deployed North Korean troops will not fight within Ukraine but will reinforce Russia’s rear areas and free up Russian manpower,” Skibitskyi said, according to the Institute for the Study of War’s daily assessment. The intelligence chief added that Putin may request up to 50,000 additional North Korean troops from Kim Jong Un as early as September 2026.
North Korea has now deployed or rotated approximately 25,000 soldiers through the Russian military since the beginning of its involvement, Ukrainian intelligence estimates. The troops have been concentrated in Kursk Oblast, where Ukrainian forces launched an incursion in August 2024 that Moscow has been working to push back.
The deployment includes access to Russia’s Rubikon Center for Advanced Unmanned Technologies, which has been operating in the Sumy-Kursk border area. The center could pass down lessons from Russian offensives in the Pokrovsk and Hulyaipole directions to North Korean forces, according to ISW analysts.
Ukrainian officials warned that any future deployment of North Korean troops inside Ukraine itself would constitute a dramatic escalation requiring the international community, particularly South Korea, to fundamentally reassess its diplomatic posture. Seoul has repeatedly warned it would consider direct military aid to Ukraine if North Korean forces fight on Ukrainian soil.
The revelation comes as Russia intensifies its aerial campaign across Ukraine. Moscow Mayor Sergei Sobyanin reported that 2,652 drones flew toward the Moscow region between August 15 and August 22, with 493 destroyed as they approached the capital, underscoring the scale of the drone war on both sides.
