South Korea's Hanwha Aerospace is intensifying efforts to position its new K9MH wheeled self-propelled howitzer, as a contender for future U.S. Army artillery programs. The system represents a critical evolution of the widely used K9 platform, adapted to meet Western demand for high-mobility, rapidly deployable artillery.
In late March, Hanwha Aerospace confirmed plans to deliver the first K9MH prototype for testing while also outlining intentions to establish a production facility in Alabama. This move underscores the company's strategy to localize manufacturing and strengthen its position in the U.S. defense market.

To build momentum, Hanwha Aerospace released a demonstration video showcasing the K9MH howitzer at its test center near Changwon. The footage highlighted the vehicle's mobility, including off-road performance and its ability to handle steep gradients, thanks to a chassis developed in cooperation with Tatra. However, the original, more detailed version of the video, reportedly including live-fire tests, was later removed, though copies quickly spread through local media.
The leaked footage provides rare insight into the K9MH system's automated loading system. The design uses a dual-feed mechanism with two separate conveyors: one for projectiles and another for propellant charges. Shells are stored vertically and then mechanically transferred into a horizontal position before loading, indicating a high degree of automation aimed at sustaining rapid fire.
Based on the available footage, the firing cycle, from shot to shot, takes approximately 7.5 seconds. In one demonstrated sequence, the system fired nine rounds in just over 59 seconds, excluding the initial loading time. This places the system firmly in the category of high-rate-of-fire artillery systems designed for intensive fire missions.
In terms of performance, K9MH howitzer closely matches Swedish Archer artillery system, long considered a benchmark for automated artillery. Archer system's loading cycle typically ranges from 8 to 9 seconds, delivering a similar rate of 8-9 rounds per minute. However, Archer system maintains an advantage in deployment speed, requiring around 23 seconds from halt to first shot and 34 seconds to leave position, compared to 20 and 50 seconds respectively for the K9MH.
K9MH howitzer may also outperform Germany's RCH 155 system in raw loading speed, as the latter is rated at "over 8 rounds per minute". Yet RCH 155 system offers a different operational concept, with its defining capability being the ability to fire on the move, eliminating the need to stop before engaging targets.
Overall, K9MH howitzer demonstrates a strong balance between firepower, automation, and mobility, positioning it as a serious competitor in the next generation of wheeled artillery systems. At the same time, its slightly longer withdrawal time compared to peers highlights the ongoing trade-offs between rate of fire, survivability, and tactical flexibility in modern artillery design.
