In a significant development for the world of artillery and military capabilities, BAE Systems has successfully conducted a test-firing of 155-millimeter projectiles from the M109-52 self-propelled howitzer.

This test not only demonstrates the compatibility of the M109A7 platform with the Rheinmetall L52 155mm, 52-caliber cannon but also heralds the arrival of a new and improved artillery system that promises to push the boundaries of range and lethality.

The M109-52 is a substantial upgrade to the existing M109A7 platform, merging it with the highly regarded Rheinmetall L52 cannon, known for its impressive range and accuracy. This synergy is set to deliver an enhanced combat capability that could reshape the landscape of artillery engagement.

In this article, we explore the details of this upgrade, its impact on range, and the potential implications for the US Army.

The M109-52: Expanding Capabilities

At its core, the M109-52 is about extending artillery systems’ reach. To achieve this goal, the M109A7 platform underwent a significant transformation by incorporating the Rheinmetall L52 155mm, 52-caliber cannon. This alteration proved to be a pivotal moment in enhancing the platform’s capabilities.

One of the most notable changes brought about by this upgrade is the increase in range. An unassisted shell fired from the M109-52 can now reach an impressive distance of 30 kilometers (18.6 miles) compared to the previous range of 24 kilometers (15 miles).

This enhancement alone offers a substantial tactical advantage, allowing for the engagement of targets at extended distances.

Furthermore, the upgrade has doubled the range of a rocket-assisted shell, making it possible for the M109-52 to reach out to a staggering 60 kilometers (37 miles). This substantial increase in range for both unassisted and rocket-assisted shells extends the M109-52’s versatility and effectiveness in a variety of combat scenarios.
