DESCRIPTION
The M109A6 Paladin 155 mm along with the M992A2 Field Artillery Ammunition Supply Vehicle (FAASV) provides the primary indirect-fire support to Armored Brigade Combat Teams (ABCT), Infantry Brigade Combat Teams and Stryker Brigade Combat Teams. 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 Fiscal Year 2018.
The M109A7 SPH and M992A3 CAT comprise a modernization effort to improve size, weight, power, cooling, readiness, force protection and survivability. They increase M109A6 Paladin and the M992A2 FAASV platforms’ sustainability 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 and 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.
Extended Range Cannon Artillery (ERCA) uses the existing M109A7 PIM chassis and modernizes the vehicle above the turret ring to increase range and rate of fire in coordination with ammunition upgrades. Project Manager Combat Ammunition Systems 155 mm ammo programs are critical to achieving range and lethality goals. Programs remain in sync via Howitzer configuration steering boards.
BENEFIT TO THE SOLDIER
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.
ERCA brings an all new or modified cab, extended range, increased rate of fire and improved ammunition stowage and handling. Benefits include regained lethality overmatch; a demonstrated range of 70-plus km; 300 percent improvement in area coverage for 155 mm; 30 percent increased range for legacy ammo and improved breech reliability.
