M1064A3 Self-propelled 120mm Mortar / M106 Self-propelled 107mm Mortar (original) (raw)

m1064A3 photoThe M1064A3 is a member of the M113A3 Vehicle Family developed and produced by FMC Corporation. Power is supplied by a 275hp Detroit Diesel 6V53T turbocharged diesel engine driving through an Allison X200-4 (cross-drive) transmission.

The M1064A3 incorporates all of the mobility, reliability improvements of the M113A3, including powertrain, engine diagnostics, driver's station, and electrical system. Survivability is enhanced through the use of external fuel tanks.

The M1064A3 has the same silhouette as the M113A3 Personnel Carrier and features a welded-in cross beam, additional floor support structures to withstand mortar reaction forces, and an enlarged three-piece top firing hatch. The 120mm weapon has a 90 traverse for firing over the rear of the vehicle.

The M106 107mm Mortar Carrier has a 4.2 inch (107mm) M30 mortar mounted on turntable in the rear which fires through a large hatch in the roof. The baseplate for the mortar is mounted externally on the left side of the vehicle for use when firing the mortar dismounted. The M125 is of similar design, carrying a 81mm mortar. Kits to convert M106 and M125 vehicles to the M1064A3 configuration are available.
