Hanwha Aerospace unveils K9MH wheeled self-propelled howitzer as new contender for U.S. Army artillery modernisation

The system has been presented by Hanwha Defense USA as a candidate for ongoing U.S. Army modernisation efforts. It represents a less common design approach, combining a truck-based chassis with a fully automated turret.

The K9MH integrates a large automated turret derived from developments associated with the K9A2 variant. It is mounted on an 8×8 truck chassis, such as the Tatra platform, although alternative carriers of similar size and payload capacity may be used.

The system retains the Hyundai WIA CN98 L/52 gun, ensuring firepower comparable to the tracked K9 system. A longer 58-calibre barrel may also be offered as an option.

The howitzer is designed to achieve a rate of fire of up to eight to nine rounds per minute. Its maximum range depends on the type of ammunition employed.

The onboard ammunition storage is expected to hold 40 complete rounds. The loading process is fully automated, supporting rapid and sustained firing operations.

The turret is also designed for compatibility with the tracked K10 ammunition resupply vehicle. This integration supports continuous operations in the field.

The system is expected to deploy rapidly, with a setup time of under 30 seconds. On paved roads, it can reach speeds of up to 100 km/h and operate over distances of up to 700 kilometres.

The K9MH has been developed with export markets in mind. In addition to the United States, the system is reportedly being considered for programmes such as Spain’s planned acquisition of similar artillery systems.

To support potential U.S. procurement, Hanwha is expected to propose a variant based on a chassis commonly used by the U.S. Army. This could involve platforms produced by domestic manufacturers.

The company has also outlined plans to localise production in the United States. These proposals include establishing a major production facility in Alabama and a separate ammunition plant in Arkansas.

The unveiling of the K9MH highlights continued competition in the self-propelled artillery segment. It also reflects growing interest in wheeled systems that combine mobility, automation and firepower.
