MRL 130mm K136 Kooryong

The K136 Kooryong is a South Korean 130mm multiple rocket launcher system, capable of firing 36 rockets in 20 seconds. It is typically mounted on a KM809A1 6x6 truck chassis.

Developed in the late 1970s by the Agency for Defense Development, the K136 was designed to counter North Korea's overwhelming artillery capabilities and its deployment of Soviet-designed multiple rocket launchers. The system officially entered service with the Republic of Korea Army in 1981, providing a rapid-fire, area-denial capability to defend against potential massed infantry and armor breakthroughs. While the Kooryong has never seen active combat, it served for decades as a critical component of South Korea's frontline deterrence along the Demilitarized Zone. In recent years, the K136 has been progressively phased out of active service in favor of the modern K239 Chunmoo, with surplus systems being considered for transfer to international partners like the Philippines.
