The Chunmoo also called K239 K-MLRS is a multi-caliber launch rocket system designed and manufactured by the South Korean Company Hanwha Corporation. It is a new generation of artillery weapons able to fire different calibers of rockets. The South Korean government awarded a development contract to Hanwha in 2009, and the development of the Chunmoo was completed in 2013. It entered into service with the South Korean Army (ROK) in 2014.

ArmamentThe Chunmoo K-MLRS carries two launch pods able to fire different calibers of rockets. It can fire 130 mm non-guided rockets (20 rockets to each pod), 227mm non-guided rockets (6 rockets to each pod), and 239mm guided rockets (6 rockets to each pod). The pods are mounted on a single turntable which has a traverse of 360°. In the firing position, four hydraulic jacks are lowered on the ground, one on each side and two at the rear of the truck chassis. The Chunmoo can fire 130mm, 227mm, and 239mm rockets. Rockets can be fitted with HE-FRAG (High-Explosive Fragmentation), incendiary, smoke, illumination, cargo warheads with anti-tank or pre-fragmented anti-personnel sub-munitions. The types of rockets can be mixed (for example 1 container of 20x 130mm and 1 container of 6x 239mm). The 130mm rockets have a range of 36 Km while the larger 230 mm-class rockets have a range of about 80 Km for the non-guided one and 160 Km for the guided variant. The Chunmoo 239mm rocket is a guided artillery rocket that enhances its precision by adding up guidance and a control system. It has two types of operation functions, impact bursting and delay bursting which can be selected by the operator. Impact bursting mode is used as anti-personnel or to destroy facilities by detonating warheads when the rocket hits the target. Delay bursting mode is selected to destroy inside buildings or bunkers with its delay function after the target impact. The Chunmoo can also use GPS/INS(Inertial Navigation System)-guided munitions provide long-range, precision-strike capabilities, enabling precision strikes fired from outside the range of the enemy's long-range missile defense system. The Chunmoo is also able to fire KTSSM (Korea Tactical Surface-to-Surface Missile). The KTSSM has a range of around 120 to 200 kilometers, depending on the variant. It is equipped with a high-precision guidance system, which includes GPS, INS (Inertial Navigation System), and terrain-matching guidance. This allows the missile to achieve a high degree of accuracy, with a CEP (Circular Error Probable) of fewer than 2 meters.

Design and protectionThe Chunmoo K-MLRS is based on an 8x8 truck chassis also manufactured by the Company Hanwha. The truck has an armored cab located at the front of the chassis that can accommodate a crew of three. It offers protection against the firing of small arms and artillery shell splinters. All the firing operations can be controlled from inside of the crew cabin or remotely from outside of the truck.

Mobility
The Chunmoo K-MLRS is based on an 8x8 military truck chassis powered by a Diesel engine developing 400 hp. It can run at a maximum road speed of 90 km/h with a maximum cruising range of 800 km. It can climb a gradient of 60% and a side slope of 30%. It can cross a trench of 1.4m and a water obstacle of 1.2m deep.

Combat Equipment
The standard equipment of the AMX-10P includes an NBC protection system, on the right side of the hull, and a heater. The vehicle can be delivered without the NBC system or the heater and optional equipment includes an NBC (Nuclear, Biological, and Chemical) detector and decontamination equipment. A white searchlight is mounted coaxially to the main armament.
