The Democratic People’s Republic of Korea (DPRK) launched a simultaneous salvo of approximately 10 short-range ballistic missiles (SRBMs) from the Wonsan coastal axis toward the East Sea (Sea of Japan) at approximately 12:30 p.m. local time on October 29, 2026.
According to trajectory data released by South Korea’s Joint Chiefs of Staff (JCS) and Japan’s Ministry of Defence, the projectiles traversed a flight envelope of approximately 250 kilometers (155 miles) at low apogees before impacting the maritime zone off the eastern coast of the Korean Peninsula, remaining outside Japan’s Exclusive Economic Zone (EEZ). Executed under 17 days after Pyongyang’s October 12 tactical missile drills, the high-density salvo utilizes North Korea’s KN-25 600mm “super-large” multiple launch rocket system (MLRS) architecture. The test demonstrates saturated barrage-strike tactics designed to overwhelm forward Allied theater air defense systems—such as PAC-3 PATRIOT and Terminal High Altitude Area Defense (THAAD) batteries—along key operational vectors.

TIMES OF DEFENCE ASSESSMENT
North Korea’s launching of a 10-missile salvo from Wonsan reflects a tactical shift in Pyongyang’s strike doctrine: prioritizing operational saturation over single-round ballistic demonstrations. While strategic strategic platforms like the Hwasong-17 and Hwasong-18 ICBMs act as global strategic deterrents, the KN-25 platform is built as a frontline theater weapon.
From an engineering and C4ISR perspective, high-density SRBM salvos present serious air defense challenges:
1. **Radar and Interceptor Saturation**: Simultaneous multi-tube salvo launches compress the engagement timeline for ground-based theater air defense systems. Firing 10 heavy 600mm guided rockets simultaneously within a brief window aims to deplete interceptor magazines (such as Patriot PAC-2/PAC-3 or South Korea’s M-SAM II) and saturate target tracking radars.
2. **Depressed Trajectory Profiles**: Flying at low apogees (~30–50 km) over a 250 km range keeps the KN-25 below optimum tracking brackets for high-altitude interceptors like THAAD, while giving lower-tier point defenses less reaction time during terminal guidance.
3. **Dual-Capable Tactical Nuclear Threat**: Mass-producing 600mm guided artillery systems provides the Korean People’s Army with a flexible delivery mechanism. By engineering the KN-25 to accommodate tactical warheads like the Hwasan-31, Pyongyang can integrate conventional saturation strikes with tactical nuclear options, raising the operational risks for Allied forces in a conflict.
