North Korea's missile program is no longer just a regional menace — it has become a working part of Russia's war machine. At home, Pyongyang keeps testing and refining its arsenal: in May 2026, state media announced a fresh round of trials covering tactical ballistic missiles, artillery rockets and precision cruise missiles, some with AI-guided controls, all supervised by Kim Jong Un. Abroad, those same weapons are being fired at Ukrainian cities, giving North Korea something no test range can offer — real battlefield data.

The result is a feedback loop with global consequences: Russia gets missiles and troops for its war in Ukraine, and North Korea gets hard currency, energy, military technology — and combat-proven weapons aimed, ultimately, at South Korea and the U.S. forces stationed there.

Key takeaways

  • North Korea's missile program spans tactical ballistic missiles, cruise missiles and long-range artillery rockets, with May 2026 tests focused on "modern warfare" upgrades including AI-guided precision, according to state media.
  • Pyongyang has supplied Russia with ballistic missiles and artillery rockets since late 2023 — around 150 missiles by some counts — and the weapons' combat use is believed to be feeding performance data back into North Korean designs.
  • The Russia link has deepened into direct deployment: Ukrainian intelligence says Moscow has stationed 120 North Korean KN-23/KN-24 ballistic missiles, six launchers and 90 North Korean personnel in Russia's Voronezh region.
  • In return, Pyongyang has received hard currency, energy supplies and military technologies worth at least $14 billion over three years, according to Bloomberg figures cited by the Atlantic Council.

The arsenal: what North Korea is building

North Korea's missile program grew out of Soviet-derived Scud technology in the 1980s and has since branched into one of the world's most diverse — and most sanctioned — arsenals. Having, as Reuters put it, "advanced the development of a series of long-range ballistic missiles and nuclear weapons capabilities," Pyongyang has in recent years concentrated on upgrading its tactical and conventional strike forces: the weapons that would be used first in any Korean conflict.

The May 2026 tests illustrate the direction. According to KCNA, North Korea's state news agency, the trials covered a "special mission warhead" on tactical ballistic missiles, long-range multiple-launch artillery rockets, and tactical cruise missiles with AI-guided control and precision navigation able to strike targets 100 km away. Kim Jong Un, supervising the tests, said the weapons and automated launch systems had been upgraded for modern warfare:

"The tests showed the weapons and automated launch systems have been successfully upgraded to 'suit the proper conditions of modern warfare so as to enhance their application to combat,' KCNA quoted Kim as saying."

South Korea's military said it detected the launch of multiple projectiles, including a ballistic missile. The 100 km figure is not abstract: central Seoul, South Korea's densely populated capital, sits well within 100 km of the Demilitarized Zone. Pyongyang has vowed to deploy the new systems near the border with the South — which it now calls its "primary foe," having formally disavowed the goal of eventual Korean unification.

The North Korea missile program's Russia connection

The program's most consequential development is not a test at all — it is the partnership with Moscow. Since Russia's full-scale invasion of Ukraine in February 2022, North Korea has become, in the Atlantic Council's assessment, "one of Russia's most direct and consequential backers, providing troops, missiles, ammunition, specialist military personnel, and labor."

The timeline, as documented by the Atlantic Council drawing on Ukrainian, U.S. and South Korean assessments:

  • Late 2023: Pyongyang begins supplying Russia with ballistic missiles and artillery rockets for use against Ukraine — reportedly around 150 missiles to supplement Moscow's own Iskander arsenal.
  • June 2024: Russia and North Korea sign a mutual defense pact during Vladimir Putin's visit to Pyongyang.
  • October 2024: North Korea sends an estimated 14,000 troops to Russia's Kursk region after Ukraine's cross-border incursion.
  • August 2026: Ukrainian intelligence assesses that Moscow has deployed 120 KN-23/KN-24 short-range ballistic missiles, six launchers and about 90 North Korean personnel to Russia's western Voronezh region, to operate alongside Russia's 112th Guards Missile Brigade. Days earlier, President Volodymyr Zelenskyy warned the Kremlin was preparing to deploy between 30,000 and 50,000 North Korean troops on Russian soil.

A May 2025 report by the Multilateral Sanctions Monitoring Team found Moscow using North Korean weapons in attacks on Ukraine's critical infrastructure and civilian population. The exchange is not charity: in return, Pyongyang has received hard currency, energy supplies and military technologies worth at least $14 billion over the past three years, per Bloomberg figures cited by the Atlantic Council.

Why Ukraine's skies are the proving ground

Ukraine is where North Korean hardware meets reality — and the results flow straight back to Pyongyang's engineers. Reuters noted that the combat use of North Korean-supplied weapons in Ukraine "is believed to have given Pyongyang valuable battlefield data for its arsenal." No domestic test program can replicate firing missiles at defended targets through contested airspace; Ukraine's air defenses are, involuntarily, North Korea's most demanding test range.

The dynamic is sharpening Ukraine's vulnerability. Kyiv faces acute shortages of U.S.-made Patriot interceptors — its most effective defense against ballistic missiles — with Western deliveries reportedly down to one-third of 2025 levels, while Russia seeks to nearly triple the number of ballistic missiles it can launch simultaneously. In a deadly August 11, 2026 attack on Zaporizhzhia, Zelenskyy said a North Korean missile was used, ten Ukrainian civilians were killed, and none of the missiles were intercepted.

This is the strategic significance of the Russia link: every North Korean missile Russia fires at Ukraine is simultaneously a live-fire trial for weapons that may one day target Seoul, Tokyo or U.S. bases in the Pacific.

What it means for Korea — and what to watch

For the Korean Peninsula, the implications are direct. The systems Pyongyang is refining — tactical ballistic missiles, 100 km-range AI-guided cruise missiles, massed artillery rockets — are designed for a Korean war, not a Ukrainian one. Their deployment near the DMZ, combined with the North's designation of the South as its "primary foe," compresses warning times for Seoul to minutes.

Three indicators matter most:

  • Test cadence and type. Further trials of longer-range systems or new warhead types would signal the program moving beyond the tactical tier.
  • The Voronezh deployment. Whether North Korean crews actually operate launchers in Russia — and whether more missile types follow the KN-23/KN-24 — will show how institutionalized the partnership has become.
  • What Russia gives back. The $14 billion in currency, energy and technology is the known price. Any evidence of Russian assistance with North Korean submarine, satellite or ICBM programs would mark a dangerous escalation in the other direction.
