The Republic of Korea Army has begun deploying the Hanwha Chun-Mu long-range multiple rocket system (LRMRS), South Korea’s Defence Agency for Technology and Quality (DTAQ) said in a 4 August statement.
IHS Jane’s reported in December 2014 that Hanwa had completed development of the Chun-Mu LRMRS, which is intended to supplement and eventually replace the Doosan K136 Kooryong 130 mm 36-round unguided rocket system.
