- Hanwha Aerospace unveiled the High-Performance Launch Rocket System (HPRS) at ADEX 2025 as a lighter, mobile version of the K239 Chunmoo.
- The HPRS uses a single CTM missile pod and a 6x6 chassis while retaining Chunmoo’s fire-control technology and compatibility with its munitions.
Hanwha Aerospace this week presented a new mobile rocket artillery concept, the High-Performance Launch Rocket System, or HPRS, at ADEX 2025.
Military expert Mason Yonhak reported that the HPRS was shown for the first time, and that the system represents a lighter, more transportable adaptation of the Chunmoo family intended for coastal defense and expeditionary use.
The HPRS is described as a reduced-weight variant of the K239 Chunmoo, coming in at under 30 tonnes and mounted on a 6×6 truck chassis rather than the Chunmoo’s 8×8. Hanwha says the change trades payload volume for mobility: a single missile pod reduces mass and permits easier road movement and sea transport. That lighter footprint, the company argues, improves the system’s suitability for operations on less developed road networks and its compatibility with a variety of naval and landing platforms.
Hanwha retained the Chunmoo’s core firing technology and common operating procedures, the company says, including stabilization and the fire-control capabilities used in the unmanned Chunmoo launcher. According to the development briefings at ADEX, HPRS will be able to employ a range of Chunmoo-compatible munitions, including a pod of twenty 131 mm unguided rockets, a pod of six CTG-80 239 mm guided rockets, and in principle the single CTM-290 600 mm tactical ballistic missile with assorted payload options. Company materials and analysts at the show stressed the logistics and training advantages of a family of systems that share procedures and maintenance routines.
Central to the HPRS concept is the CTM-MR, a medium-range anti-ship ballistic missile (ASBM) being developed for the platform. The CTM-MR is currently under development with an expected completion date in 2027, the briefings said. Range is reported at between 50 and 160 kilometers and the circular error probable is given as nine meters. The missile uses a composite propellant mix, Hanwha documents indicate, and is intended as a lower-cost anti-ship ballistic option for countries with long coastlines.
At ADEX, Hanwha highlighted the mobility trade-offs that the HPRS is designed to accept. The shift to a 6×6 chassis and a single-pod launcher reduces strategic lift needs and broadens options for shore-based or shipborne stowage. Company presentations emphasized that the system keeps the Chunmoo’s digital fire-control architecture while shrinking the logistics tail required to deploy salvo-capable fires from dispersed positions.
Not all program elements are finalized or publicly confirmed. Hanwha has not confirmed whether the HPRS will field a companion reloading vehicle similar to the Chunmoo support concept; program materials state only that such a vehicle could, in theory, enable reloading in as little as seven minutes. The firm also flagged that the CTM-MR remains under development and that final performance numbers will be set as testing progresses.
Development of HPRS is framed by Hanwha as a response to operational needs for more mobile and affordable strike options. The company positions the system as suitable for coastal defense, rapid deployment forces and navies that can host smaller launch platforms. Hanwha has presented HPRS as part of a broader effort to expand the Chunmoo family into lighter, mission-specific variants that preserve common technical and procedural links to the base system.
