“The 52-caliber version of the M109 self-propelled howitzer prototype is the subject of a research and development agreement between the US Army and BAE Systems.
BAE will hasten 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 cannon is an improvement over the current 39-caliber M109A7 platform in the M109-52.
The M109-52 is now one of the Army’s potential answers for 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, was canceled.
