American Rheinmetall supports successful test of M109 Self-Propelled Howitzer modified with Rheinmetall’s combat-tested 52-calibre cannon.


Press Release, Düsseldorf, 10 October 2023: Rheinmetall and BAE Systems have successfully completed a live fire test of the M109 Self-Propelled Howitzer (SPH) modified with Rheinmetall’s L52 155mm, 52-calibre cannon.

The M109-52 is a significant, low-risk, high-performance upgrade to the current 39-calibre cannon and provides additional range required in large-scale operations. The test, conducted at Camp Ripley, MN, proved the compatibility of the L52 cannon with the M109A7 platform during the live fire exercise.

“Integrating Rheinmetall’s world-class, battle-tested L52 artillery cannon system into the M109 platform will return tactical fires overmatch to the US Army in a capability assured, timely, low-risk manner,” said Joe Chan, VP of Business Development at American Rheinmetall Munition.

Rheinmetall’s L52 artillery cannon system is currently the backbone of nine NATO and allied partner nations’ tactical artillery forces. By integrating this world class, combat proven system on the M109 platform, the US will achieve expanded interoperability on day one with battlefield partners. Notably, the cannon system has become a favourite for Ukraine due to its accuracy, range and durability in combat.

The M109-52 offers a low-risk pathway to rapid development, putting this significantly improved capability in the hands of our warfighters quickly to ensure overmatch on the battlefield. By combining two mature systems, Rheinmetall and BAE Systems avoid many of the technical risks associated with similar lethality upgrade efforts. The criticality to deliver improved artillery capabilities is underscored by the ongoing conflict in Ukraine and is a key part of the Army’s number one modernisation priority – long-range precision fires.

The team plans to conduct additional testing in 2024, which will highlight extended range across a variety of ammunition combinations.

Rheinmetall features their systems house solutions for platform, cannon, projectile and propellant technology across the Artillery ‘eco-system’ at this year’s AUSA Annual Meeting & Exhibition in Washington, DC, with a display at the Rheinmetall booth. A full-sized M109-52 system features on the BAE Systems booth for attendees to view throughout the show.
