“The 52-caliber variant of the M109 self-propelled howitzer prototype has been the subject of a research and development deal between BAES Systems and the US Army.
BAE will expedite the system’s development under the Cooperative Research and Development Agreement with the US Army Combat Capabilities Development Command Armaments Center (DEVCOM-AC).
The Rheinmetall L52 155mm, 52-caliber gun is an improvement to the existing 39-caliber M109A7 platform.
The M109-52 has become one of the Army’s possible options for meeting its long-range precision fires needs after the Extended Range Cannon Artillery program, which sought to deploy a 58-caliber cannon but was abandoned due to excessive barrel wear.
