Hanwha Aerospace has unveiled a new 6×6 rocket launcher system named High-Performance Launch Rocket System (HPRS) in Australia. The HPRS is a single-pod launcher with a configuration similar to the U.S. M142 HIMARS and is designed for lightweight deployment and high mobility. It serves as a lighter version of the K239 Chunmoo multiple launch rocket system, weighing under 30 tons, and is equipped with four CTM-MR anti-ship ballistic missiles (ASBMs). The HPRS platform prioritizes rapid transport and firing capability while maintaining compatibility with Chunmoo technology.

The High-Performance Launch Rocket System (HPRS) differs from the previously revealed unmanned K239 variant. While both systems are developed under the direction of South Korea’s Marine Corps and emphasize advanced technology for ship-based launch capabilities, the HPRS is a manned system. Both programs are part of a broader initiative to enhance long-range artillery fire missions from surface ships. The HPRS can be launched from amphibious and naval platforms using stabilization and fire control innovations derived from the unmanned Chunmoo concept.
The CTM-MR missile, which is integrated with the HPRS, is under development and expected to be completed by 2027. It is designed to serve as a cost-effective anti-ship ballistic missile (ASBM) option for countries with extensive coastlines. The missile has an operational range of 50 to 160 kilometers and a circular error probable (CEP) of 9 meters. It utilizes a composite propellant. The CTM-MR was first presented at the ADAS 2024 exhibition in Manila.
If the HPRS’s rocket launcher unit is indeed based on that of the K-239 Chunmoo, we can imagine that additional munitions compatible with the HPRS could include the CGR-80 guided rocket, which has a range of 30 to 80 kilometers and a CEP of 15 meters. On the Chunmoo, each CGR-80 pod contains up to six rounds. All munitions, including the CTM-MR and CGR-80, are classified under United Nations number 0181 and NATO Munitions Designation Code 1.1E, indicating compliance with international standards.
The K239 Chunmoo MLRS, which seems to serve as the foundation for HPRS development, entered service in 2014 following development from 2009 to 2013. It was designed to replace the K136 Kooryong and provides multi-caliber launch capability. Chunmoo can launch 131 mm unguided rockets, 230–239 mm guided rockets, and 600 mm tactical ballistic missiles. Each launcher carries two pods, each capable of carrying various munitions, including 20 unguided 131 mm rockets, six guided 239 mm rockets, or tactical ballistic missiles such as the CTM-290.
The Chunmoo is mounted on an 8×8 truck chassis and features GPS-aided inertial guidance, an automated fire control system, and a protected cab for a three-person crew. It is capable of firing 12 guided rockets in one minute and can be reloaded in approximately seven minutes. The system is compatible with a separate ammunition support vehicle on the same chassis and includes capabilities for both remote and onboard firing.
