The M109A6 Paladin 155 mm Self-Propelled Howitzer (SPH) along with the M992A2 Field Artillery Ammunition Supply Vehicle (FAASV) provides the primary indirect-fire support to Armored Brigade Combat Teams (ABCT). Like the earlier M109 models, the M109A6 Paladin is a fully tracked, armored vehicle. The M109A6 Paladin configuration was achieved through modifications to earlier-built M109A2 and A3 vehicle hulls and the introduction of an entirely new cab and cannon assembly.

The M109A7 Self-Propelled Howitzer (SPH) and M992A3 Carrier Ammunition Tracked (CAT), formerly known as the Paladin Integrated Management (PIM) program, will replace the current M109A6 Paladin and the M992A2 FAASV respectively starting in FY17. The M109A7 SPH and M992A3 CAT vehicles are currently in Low-Rate Initial Production (LRIP). This next-generation Howitzer provides enhanced capabilities to maintain Army dominance on future battlefields, and is one of the most critical vehicle modernization programs.

The M109A7 SPH and M992A3 CAT comprise a modernization effort to improve size, weight, power, cooling, readiness, force protection and survivability, and to increase sustainability of the M109A6 Paladin and the M992A2 FAASV platforms through 2050. The platforms will also be fitted with Blue Force Tracker capability to ensure situational awareness with other friendly forces. The program has leveraged Bradley commonality for key components—engine, transmission, final drive, suspension—in a new hull. The new electric-gun drives and rammer components, as well as a microclimate air conditioning system, will be powered by the common modular power system utilizing a 600-volt onboard electrical system in the existing cab and cannon assembly.


These upgrades and better communications technology will significantly improve the warfighter’s battlespace awareness and reduce the logistics footprint within the ABCT. Once delivered to the field, the M109A7 SPH and M992A3 CAT will give ABCT commanders a more capable and sustainable vehicle, providing them with increased confidence in their artillery fleet.
