North Korea said on September 24, 2026, that it successfully test-fired upgraded North Korea 240mm rockets with autonomous guidance on September 22, state media KCNA reported, claiming a major boost to frontline firepower along what Pyongyang calls its southern border with South Korea.
The rockets can strike targets 100 kilometers away on a ballistic trajectory and up to 115 kilometers in a combined glide mode, KCNA said, describing an “autonomous pinpoint guide system” that proved accuracy and extended range in the Tuesday firing.
Range that reaches deeper into the South
Older 240 mm systems were often assessed near a 70-kilometer reach focused on the Seoul metro area. Yang Moo-jin of the University of North Korean Studies said the upgraded envelope could threaten US installations at Pyeongtaek and Osan plus parts of northern Chungcheong Province.
Pak Jong-chon, vice-chairman of the Central Military Commission who oversaw the test, stressed concentrating the “deadliest and most destructive” attack forces on the southern border, KCNA reported—language that fits Pyongyang’s post-2023 framing of inter-Korean relations as two hostile states.
Conventional pressure beside the nuclear arsenal
The test continues a pattern of tactical upgrades Kim Jong Un has highlighted, including June firings of rocket launchers and tactical missiles billed as southern-border defenses. Extending guided MLRS range tightens the conventional threat timeline for South Korean and US forces even without nuclear use.
Seoul and Washington typically treat such KCNA announcements as both military signaling and domestic propaganda. Still, a precision-guided 115-kilometer rocket changes planning for air bases, logistics hubs, and early-warning nodes that sit just beyond legacy artillery belts.
North Korea 240mm rockets amid summit week
The disclosure landed while US–China summit pageantry dominated headlines and European capitals warned about Russian hybrid risks—another reminder that the Korean Peninsula escalation ladder runs on its own calendar. Allies will watch whether follow-on deployments move the new rockets into forward batteries.
For now, the North Korea 240mm rockets claim is an unverified but strategically pointed message: Pyongyang intends to keep thickening conventional strike options that can hold Seoul and US forces at risk within minutes, complicating any crisis response short of full-scale war.
