North Korea's renewed ballistic missile exports to Russia are not only sustaining Moscow's campaign in Ukraine but also accelerating Pyongyang's weapons development and military learning, with consequences that may ultimately reverberate across Northeast Asia.
Multiple media outlets reported this month that North Korea has resumed shipments of KN-23 and KN-24 tactical ballistic missiles and mobile launcher units to Russia. Ukrainian military intelligence also indicated that Pyongyang is preparing to deploy an additional 30,000 troops to the frontline. Ukrainian President Volodymyr Zelensky, citing intelligence assessments, warned that Russia has been readying accommodation facilities in the southwestern Voronezh region since June to host incoming personnel.
Simultaneously, North Korean state media confirmed plans to expand domestic missile manufacturing capacity 2.5-fold over five years to support growing exports. Early battlefield deployments of the KN-23 suffered from severe inaccuracy, with error margins reaching up to 1,500 meters. However, joint technical modifications by Russian engineers have drastically refined the weapon's precision, tightening its error margin to between 1 and 5 meters.
A live-fire testing ground for Pyongyang
Western and Ukrainian officials caution that these transfers transform the war in Ukraine into a live-fire testing ground for North Korea's military hardware. North Korean forces are gaining operational combat experience and enhancing weapons systems that directly threaten stability across the Asia-Pacific region. As Tianran Xu and Jaewoo Shin note in an Open Nuclear Network report, the KN-23 achieves an extended maximum strike range of approximately 600 kilometers, enabled by a wider 1.1-meter airframe housing more solid propellant. This allows it to target high-value assets deep across the Korean Peninsula using non-ballistic depressed trajectories. By comparison, the KN-24 reaches a shorter maximum range of roughly 400 kilometers but provides sufficient coverage to saturate frontline military installations and logistics hubs across South Korea.
On how these missiles may be deployed in Ukraine, Marcus Welsch and other writers in a report this month for the Center for Strategic and International Studies (CSIS) describe Russia's long-range strike campaign as a coercive punishment strategy centered on geographic targeting rather than the pursuit of air superiority. Russia combines high-precision ballistic and cruise missiles with large numbers of low-cost Shahed-type drones to bypass air defenses. These attacks target energy grids, transport infrastructure, industrial hubs and major urban centers, particularly during winter, to intensify civilian, economic and political pressure. Drones provide persistent attrition, while missiles strike high-value targets and extend the battlefield deep into Ukraine's rear.
But as the increasingly stalemated Russia-Ukraine War drags on, such an intense and prolonged campaign may already have strained Russia's ballistic missile production capability to the point of requiring external assistance to maintain strikes on Ukraine. Ukrainian defense source Militarnyi reported in May 2026 that Western sanctions and Ukrainian strikes have derailed Russia's Iskander-M ballistic missile production targets. Procurement documents show that the Kolomna Machine-Building Design Bureau ordered 1,202 9M723 Iskander-M missiles for 2024–2025, but Russian forces deployed just 813 total ballistic missiles across all types during that timeframe—including foreign North Korean imports and air-defense munitions—while maintaining a flat reserve of 200–250 missiles. Intelligence analysis of recovered debris confirms newly manufactured missiles are deployed immediately after production, proving Russia's failure to build stockpiles and highlighting how systematic attacks on defense supply chains have forced the military into a severe manufacturing deficit.
Scale of North Korean production
Looking at the scale of North Korea's ballistic missile production, A.B. Abrams mentioned in an August 2024 article in The Diplomat that the country's ceremonial commissioning of 250 tactical launchers carrying 1,000 KN-24 short-range ballistic missiles demonstrates an unprecedented peacetime industrial capacity. Equipping those 250 launchers would require annual production of 200 to 300 missiles, potentially exceeding 400 when reload stocks are included. That output would surpass global ballistic missile production rates except for Russia's wartime Iskander-M manufacturing surge.
But what does North Korea get in return for its extensive military assistance to Russia, encompassing munitions, troops and ballistic missiles? A March 2026 report from the Institute of National Security Studies (INSS) says North Korea may have earned US$7.67 billion to $14.4 billion by supporting Russia's war effort between August 2023 and December 2025. Munitions exports netted $7.05 billion to $13.78 billion, while deploying 21,000 troops generated $620 million in wages and compensation. Physical goods, food, and hard cash comprised only 4% to 19.6% ($580 million to $1.5 billion) of delivered payments.
Revenue from arms sales and troop deployments, combined with access to Chinese capital, may be contributing to signs of stronger economic activity in North Korea, according to The Wall Street Journal last month. The North Korean economy grew by 3.7% in 2024, while major housing projects, businesses, electric vehicles and digital services have increasingly reshaped Pyongyang. North Korea may have also received various military technologies from Russia, including for its new nuclear-cruise missile-armed submarine.
These developments have direct implications for South Korea and Japan, which face the prospect of a more capable North Korean missile force. The South Korean defense buildup is already accelerating in response, while the broader Sino-Russian cooperation in the Arctic and Indo-Pacific adds another layer of complexity to regional deterrence. As the war in Ukraine continues, Pyongyang's strategic dividends from its missile pipeline to Moscow are likely to grow, reshaping the security landscape from the Korean Peninsula to the wider Indo-Pacific.
