North Korea has become one of Russia’s most important foreign military suppliers, providing between 25% and 40% of Moscow’s artillery ammunition needs, and delivering millions of rounds of ammunition, ballistic missiles, and hundreds of artillery systems since 2023. In a document provided in response to a Kyiv Post inquiry, Ukraine’s Military Intelligence (HUR) said the scale and regularity of deliveries indicate that military-technical cooperation between Pyongyang and Moscow has become “systemic.”JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official. According to the agency’s assessment, North Korea currently occupies a “key position” among Russia’s foreign suppliers of weapons and military equipment, supplying between a quarter and two-fifths of the artillery ammunition used by Russian forces. HUR said that, since June 2023, Russia has received more than 100 KN-23 and KN-24 ballistic missiles together with their launchers from North Korea. At least 80 of those missiles have already been used, the agency said. The first reported use of North Korean ballistic missiles by Russia occurred on Dec. 29, 2023, when one missile landed in a field in Ukraine’s Zaporizhzhia region. The missiles were used again on Jan. 2, 2024, during a massive strike on Kharkiv that killed two people and injured 62 others. Reports in 2025 suggest that the missiles have become more accurate as the war has progressed. Pyongyang has also delivered more than 600 artillery systems of various types and calibers, including M-1989 Koksan 170mm self-propelled guns, M-1991 240mm multiple-launch rocket systems (MLRS), 107mm Type 63 rocket launchers, self-propelled anti-tank missile systems, D-74 122mm towed guns, and Type 76 140mm mortars.
