North Korean-made KN-23 solid-propellant, road-mobile short-range ballistic missiles (SRBMs) have been used within the Russia-Ukraine warfare since not less than December 2023, each by Russian forces and certain for a time by one in all North Korea’s personal missile models. Restricted public info, nearly all from Ukrainian authorities sources, stories that the KN-23 initially demonstrated reliability and accuracy issues. Each points appear to have been resolved since then, in accordance with more moderen reporting, with a number of allegations that Russian help helped enhance the missile’s accuracy.
Of those two claimed issues, the accuracy points appear to be extra credible given their sourcing. It is usually believable that Russia offered technical help to handle this. The almost definitely state of affairs is that the KN-23’s capability to entry satellite tv for pc updates like GPS was initially being blocked by Ukrainian digital warfare which Russia was later in a position to assist the North Koreans overcome, somewhat than extra in depth accuracy enhancements.
Associated reporting that Russia has utilized features of KN-23 know-how to its personal comparable Iskander missiles is believable to the extent it considerations enhancing features of missile manufacturing, however much less believable regarding potential fixes to the Iskander’s capability to penetrate missile defenses or the terminal homing portion of its steerage system.
Probably the most vital enhancements to the KN-23 missile, and particularly to North Korean road-mobile missile operations, have most likely come from the North Koreans taking part in Russian use of the KN-23, observing general Russian road-mobile missile operations within the face of Ukrainian missile defenses and counterstrikes, and working North Korea’s personal KN-23 launch unit in Russia dealing with those self same challenges. Though unproven, this has possible led to enhanced KN-23 efficiency and manufacturing, in addition to higher capability of the North’s road-mobile missile power to function in wartime. Which means North Korea’s theater-range missiles needs to be more practical in any future battle on the Peninsula than earlier than the warfare in Ukraine, each by way of injury functionality and survivability, though the diploma of enchancment is unsure.
Contemplating the Supply
There’s restricted public info on the KN-23’s efficiency within the Ukraine warfare and modifications to enhance that efficiency. Virtually all of it’s mentioned to return from Ukrainian authorities sources, normally from navy intelligence however generally within the state prosecutor’s workplace.[1] The Ukrainian authorities clearly has entry to radar monitoring information and particles from KN-23 strikes, in addition to any info it receives from the US and different companions. It presumably has some extent of intelligence entry to Russian KN-23-related operations, and even perhaps to these of North Koreans in Russia. However, Kyiv additionally has believable motivations to form its public pronouncements to advertise its wartime coverage targets, corresponding to acquiring or sustaining help from South Korea, the US, and different international locations involved in regards to the North Korean risk.[2] The restricted accessible info accessible and its restricted sourcing should be stored in thoughts when assessing KN-23 use in opposition to Ukraine and Russia-North Korea missile cooperation, in addition to their implications.
In-Flight Reliability
A Ukrainian regional prosecutor reported in March 2024 that about 50 KN-23/24 missiles had been launched in opposition to Ukraine by that point, however “there have been many stories of the missile exploding mid-flight.” Ukraine’s Prosecutor Normal Workplace reported in Might 2024 that “about half of the North Korean missiles” launched from Russia between December 2023 and late February 2024 “misplaced their programmed trajectories and exploded within the air.” This failure fee is at nice variance with that seen in KN-23 launches in North Korea: all 19 of the KN-23s launched from Might 2019 to November 2024, a mixture of developmental and troop coaching launches, apparently made it to affect. The Prosector’s workplace, a non-technical group, apparently decided the failed launches have been KN-23s “by their flight trajectories, pace and launch websites” (the Ukrainian navy ought to have such information) and assessed they “exploded in air” as a consequence of a scarcity of recoverable affect particles.
Given the launch historical past in North Korea, which included operational troop coaching launches, it’s unlikely many in-flight failures of KN-23s launched from Russia resulted from systemic or production-quality issues. As these have been Russia’s first operational launches of this foreign-provided missile system, lack of operator coaching and expertise might need performed a job. It is usually unclear the extent to which the Prosecutor Normal’s Workplace was conscious of any interceptions of those KN-23s by Ukrainian-operated Patriot missiles, which began arriving in April 2023. Some incoming KN-23s could have additionally veered astray as a result of their steerage methods have been efficiently jammed by Ukrainian digital warfare property.
Regardless of the case, there has not been further reporting of KN-23 in-flight reliability issues in opposition to Ukraine since Might 2024, nor any reporting of reliability-related modifications made to the KN-23. Thus, to the extent there was a major reliability difficulty, it apparently has been addressed.
Missile Accuracy
Many of the preliminary protection of KN-23 efficiency issues in Ukraine reported poor accuracy. The Prosecutor Normal said in February 2024 that solely two of 24 KN-23/24s just lately fired in opposition to Ukraine had been “comparatively correct” given their proximity to navy targets; the missiles have been recognized as North Korean primarily based on affect particles and their “attribute flight paths.” Protection Intelligence of Ukraine reported in December 2024 that attacking KN-23s have been “primarily based on ‘outdated applied sciences’ that have an effect on their accuracy.”
Nevertheless, from February 2025, stories began suggesting enhancements in KN-23 accuracy. In accordance with “two senior Ukrainian sources,” accuracy “all of the sudden” improved from 1,000-3,000 meters to 50-100 meters.[3] (The pinnacle of Ukrainian navy intelligence individually mentioned the earlier accuracy was 500-1,500 meters.) Improved accuracy was seen “in all of the greater than 20 North Korean ballistic missiles that hit Ukraine over the previous a number of weeks,” this “after months of inaccurate launches.” This evaluation “was primarily based on the place the missiles—recognized as North Korean by examinations at blast websites—fell in relation to the presumed goal within the neighborhood.”
It will clearly be troublesome for the Ukrainians to know the precise meant aimpoint of incoming KN-23s, particularly given the missile’s maneuvering functionality. Furthermore, Russia clearly has been concentrating on city inhabitants areas in addition to particular navy property. Even when hanging level targets, there are tactical circumstances by which offset concentrating on (aiming the missile at a location aside from instantly on the goal) might be fascinating. Engagements by missile protection interceptors that didn’t destroy the missile could cause some missiles to fall away from their initially meant targets, as can missile maneuvers to evade interception. And digital warfare in opposition to incoming missiles may also trigger them to overlook their targets. Nonetheless, a 450-2,950-meter distinction between earlier and later assessed accuracies is giant sufficient that an accuracy difficulty seems credible.
Reporting on the KN-23’s accuracy typically doesn’t handle the supply of the issue past “outdated applied sciences.” Probably the most direct rationalization is that, through the 2023-24 launches in opposition to Ukraine, the missiles solely used inertial steerage. This might be per an accuracy of not less than 500-1,500 meters, in addition to even worse accuracy because the KN-23 maneuvers or approaches its most demonstrated vary of 800 km. Utilizing solely inertial steerage additionally can be per the attribution of the accuracy difficulty to “outdated applied sciences.”
The almost definitely cause why the KN-23 would solely depend on pure inertial steerage is that Ukrainian digital warfare denied the missiles’ entry to satellite tv for pc steerage updates (like GPS), simply as reportedly occurs to some Russian Iskander and Kinzhal ballistic missiles just like the KN-23. (The precise KN-23 steerage methodology has not been revealed in open-source reporting, however use of satellite-aided navigation typically is thought to be a chance.) Restoring entry to satellite tv for pc navigation updates might give the KN-23 an accuracy on the order of 35-90 meter, in accordance with a January 2023 French suppose tank research (effectively earlier than KN-23s have been despatched to Ukraine in Fall 2023) primarily based on evaluation of craters from KN-23/24 launches in opposition to a small island utilized by the North Koreans as an affect level. That is per the 50-100-meter accuracy reported by Ukrainian sources for the “improved” KN-23s. Due to this fact, if the above ideas of what precipitated the reported KN-23 accuracy issues and the repair are appropriate, it’s extra correct to say that KN-23 accuracy in Ukraine has been “restored” somewhat than “improved,” though the KN-23 steerage methods’ resistance to digital warfare would have been improved.
Russian Fixes to North Korea?
Though Ukrainian sources don’t establish the precise fixes made to extend (or restore) the accuracy of incoming KN-23s, they do allege that the enhancements have been a results of Russian recommendation or help being included into the North Korean missiles.[4]
- In February 2025, the top of Ukrainian navy intelligence reported that “Russian missile consultants made technical modifications, resolving the difficulty”—the very same phrases utilized in a Might 2025 report attributed to “an MSMT [Multilateral Sanctions Monitoring Team] taking part state.” (Ukraine will not be an MSMT member, however it might have offered info to a member state corresponding to South Korea, whose media performed the February 2025 interview.)
- In June 2025, the top of Ukrainian navy intelligence mentioned that the accuracy enchancment “is the results of the widespread work of Russian and North Korean specialists.”
- A Might 2026 report claimed with out sourcing that “not less than one sort of just lately examined [North Korean] missile was beforehand transferred to Russia and improved in a number of methods earlier than the information of the way to produce the upgraded missiles was reportedly despatched again to North Korea.”
- A July 2026 report apparently sourced to “nameless sources inside Ukrainian navy intelligence” said that “Russian engineers obtained to check and refine” the KN-23 “in opposition to actual Ukrainian targets night time after night time, and the ensuing upgrades flowed straight again into North Korea’s personal missile program.”
- One other July 2026 report claimed with out sourcing that “Russian missile specialists embedded with this system analyzed the telemetry from every fight launch—real-world flight information that North Korea might by no means generate by home testing—and recognized the steerage system deficiencies chargeable for the errors.” Primarily based on this, the report claimed “Russia has turned the Ukraine warfare right into a live-fire growth program for North Korea’s ballistic missile power, and the upgraded designs are flowing again to Pyongyang.”
It’s believable that Russian missile consultants analyzed and identified the obvious accuracy points with the KN-23, got here up with a repair, and handed it on to North Korea, which then used that repair to replace missiles in its personal stock and future manufacturing. (It is usually doable that the North Koreans identified the issue and the Russians got here up with a repair.) If, as prompt above, the true accuracy difficulty needed to do with jamming the KN-23’s satellite tv for pc navigation replace system, Russia can be well-positioned to plan a repair. It’s extremely skilled with ballistic missile steerage, satellite tv for pc replace know-how (together with working its personal GLONASS equal to GPS), and digital warfare (corresponding to GPS jamming and spoofing, together with within the Ukraine warfare). Russia additionally would wish to have the ability to handle the Ukrainian jamming risk in opposition to its personal KN-23-like Iskander and Kinzhal missiles, and people options can be accessible to supply to the North Koreans.
This type of Russian help is extra believable than the unsourced claims of “a live-fire growth program for North Korea’s ballistic missile power.” For instance, it’s unlikely that Russia “analyzed the telemetry from every fight launch.” Fight missiles typically don’t incorporate telemetry methods, which monitor varied features of missile conduct and transmit them to missile builders, as a result of telemetry gear takes weight and house away from weapons payload and different navy capabilities, its transmissions function a monitoring beacon of the missile’s place for enemy defenses, and in-flight diagnostic information on already-deployed methods in operational use (versus in growth) typically present no offsetting profit.
North Korean Fixes to Russia?
There even have been press stories that Russia has begun utilizing features of North Korean missile know-how in its personal KN-23-like Iskander ballistic missile. These are primarily based on the next press characterization of a June 2026 briefing by a Ukrainian navy know-how researcher:
“Russia has modified the Iskander-M ballistic missile to penetrate missile protection methods and adapt manufacturing to sanctions, specifically by incorporating elements and technical options from the North Korean KN-23.
This was reported by Colonel Oleksandr Zaruba, chief analysis fellow on the State Scientific Analysis Institute of Armament and Navy Tools Testing and Certification, through the occasion “The Russian Federation’s Use of Air Assault Weapons Towards Civilian Infrastructure: Technical and Humanitarian Facets,” which was attended by a correspondent from Militarnyi.
Particularly, the missile has been outfitted with an up to date 9B899 module, which fires decoys, dipole reflectors, and warmth traps through the terminal part of flight.
The onboard methods are tailored to function in lively scanning mode and detect blind spots within the visibility of air protection radar methods. The software program is often up to date.
New variations of the missile produced after 2023–2024 use a quicker processor to course of photographs acquired by the optical homing head, which will increase the chance of goal recognition, detection, and destruction.
To ramp up manufacturing, components and technical options utilized in North Korea’s KN-23 have been built-in into the Iskander-M missile.”
Probably the most believable of those claims is that the Russians realized classes from North Korean KN-23 manufacturing that they drew upon to facilitate their very own manufacturing of the Iskander. It is smart that, as a part of Russia’s buy of KN-23s for its personal use in opposition to Ukraine, Russian consultants got entry to KN-23 manufacturing info and even factories. It additionally is cheap that the Russians found some variations in their very own and the North Koreans’ manufacturing practices that Moscow determined have been price incorporating in Iskander manufacturing.
To the extent that the opposite claims within the July 2026 briefing have been meant to be linked to North Korea, versus being claims about Russia’s indigenously-sourced enhancements to the Iskander listed together with the claimed KN-23 manufacturing classes, these claims are much less credible.[5]
- The Iskander’s reportedly upgraded “9B899 module” is the SRBM’s missile protection penetration assist (penaid) system that was first recognized in open-sources in March 2022 (effectively earlier than Russia’s acquisition of the KN-23). It’s implausible that North Korea offered vital know-how to improve the Iskander’s penaid system, for a number of causes: Russia has had expertise with penaids for the reason that Sixties, whereas penaids haven’t been confirmed on North Korean missiles; Russia has been working its personal missile protection methods since not less than the Sixties as effectively, whereas North Korea doesn’t possess any; Russia has significantly better instrumented missile take a look at ranges to evaluate penaid efficiency than does North Korea; and Russia has deployed the Iskander since 2006 and used it in opposition to Ukraine for the reason that outset of the invasion in February 2022, thus having rather more fight expertise with the missile and its penaids, in addition to with Ukrainian missile defenses, than does North Korea.
- For comparable causes, additionally it is implausible that North Korea offered vital know-how to improve the Iskander’s radar detection capabilities and its optical homing terminal steerage system.
North Korean Fixes to North Korea?
Past no matter technical inputs North Korea acquired from Russia, it’s extremely possible that Pyongyang has included into its missile manufacturing and road-mobile missile operations its personal classes realized instantly from the employment of KN-23s in opposition to Ukraine, and from observing Russian road-mobile missile operations within the Ukraine warfare extra typically. There is no such thing as a direct open-source reporting that this has occurred or on the character of any modifications made, however this can be a logical inference to make given the big variety of KN-23s expended within the Ukraine warfare (about 250 KN-23/24s reportedly had been transferred to Russia by September 2025), the necessity for KN-23s within the Ukraine warfare to deal with missile protection engagements and counterstrikes that North Korea itself has not been subjected to, the possible presence of North Korean consultants to help with Russian KN-23 operations, and the deployment of North Korean fight troops to help Russian floor operations.
Extra necessary as a possible supply of enhancements to the KN-23 missile and North Korean road-mobile missile operations, Pyongyang reportedly deployed its personal KN-23 launch unit to Russia from November 2023 to December 2025. Outdoors evaluation from Might 2026, little observed elsewhere, noticed references to this unit within the background of Korean Central Information Company and Korean Central Tv protection of the brand new museum opened in Pyongyang to have fun the deployment of North Korean fight troops to Russia. Evaluation of the museum exhibit suggests {that a} “Hwasongpho and Anti-Tank Guided Missile Unit” (the North makes use of Hwasongpho [aka Hwasong] designators for the majority of its land-based ballistic missile methods) performed ballistic missile launches as a part of the warfare.[6] A North Korean missile launch unit presently within the technique of being deployed to Russia, in accordance with an August 2026 announcement by Ukrainian navy intelligence, subsequently is in impact a redeployment.
Implications
Past the possible enchancment within the KN-23 steerage system’s resistance to digital warfare (or probably another steerage system enchancment), open-source reporting doesn’t make clear the precise advantages North Korea’s road-mobile missile power has gained from that the KN-23’s use within the Ukraine warfare. However logically, it’s extremely possible that North Korea has used its entry to details about Russia’s use of the KN-23 and Iskander missiles in opposition to Ukraine—and particularly from the North’s personal obvious employment of a missile launch unit within the warfare—to enhance KN-23 efficiency and manufacturing, and the power of its road-mobile missile power to function in wartime. North Korea’s missile power subsequently needs to be more practical in any future battle on the Peninsula than earlier than the Ukraine warfare, each by way of injury functionality and survivability, though the diploma of enchancment is unsure.
