"The M109A7 program upgrades its predecessor, the M109A6 Paladin Self-Propelled Howitzer, by implementing a new chassis design that increases survivability and allows for the integration of drive-train and suspension components common to the Bradley Infantry Fighting Vehicle. This commonality, says BAE Systems officials, reduces overall program cost and logistical footprint and provides improved mobility and system survivability.

The new M109A7 also uses technologies from previous design programs -- such as a 600-volt on-board power generation, distribution, and management system -- used with a high-voltage electric gun drive and projectile ramming systems. The state-of-the-art digital backbone and power generation ability ensures growth potential for future payloads and usability with existing battlefield network requirements…."
