South Korea's Hanwha Aerospace has unveiled the first image of a wheeled version of its K9 self-propelled howitzer, designated K9MH. The system is already positioned as a contender in future U.S. Army artillery programs and is expected to compete globally with platforms such as the CAESAR and RCH 155

Development of the K9MH started only in 2024, highlighting the speed of South Korea's defense industry. According to Hanwha, testing is scheduled to begin in early 2026, with the program expected to be completed by June 2027.

The first high-quality image of the system surfaced online via unofficial sources and was likely taken at Hanwha's test facility near Changwon.

The image shows a new artillery module equipped with a CN98 155 mm/52-caliber howitzer. Unlike earlier K9 variants, the K9MH features an autoloader, enabling a rate of fire of 8–9 rounds per minute. The module carries 40 projectiles and 192 propellant charges. The crew is reduced to 2–3 personnel, all located in a protected cabin.

The system is mounted on an 8×8 chassis produced by Tatra Trucks, a widely used solution for wheeled artillery. At the same time, the artillery module is platform-agnostic and can be integrated onto other chassis with sufficient payload capacity.

Before firing, the system deploys large outriggers to stabilize the platform. Hanwha states that the K9MH can fire its first round within 20 seconds after stopping and leave the position in less than 50 seconds.

Hanwha is placing significant emphasis on this wheeled variant. The tracked K9 has already become a global bestseller, and the K9MH is expected to build on that success. The U.S. Army is currently seen as the key customer, with the system competing as a potential replacement for the M109 Paladin.

In addition, Hanwha has reportedly secured access to a 58-caliber gun developed under the now-canceled ERCA (Extended Range Cannon Artillery). If the company resolves the issue of limited barrel life, this could provide a significant advantage over competitors.
