Mack Defense's M917A3 Heavy Dump Truck for Army
Mack Defense showcased the Mack Granite-based M917A3 Heavy Dump Truck (HDT) at the Association of United States Army (AUSA) 2018 show in Washington, D.C. Mack Defense was awarded a $296 million contract in May to produce 683 HDTs for the U.S. Army.
Based on the civilian Mack Granite model, Mack Defense optimized the M917A3 HDT to meet the current needs of the U.S. Army. Mack Defense engineers added heavier-duty rear axles and all-wheel drive, while increasing the suspension’s ride height to create a heavy dump truck capable of meeting the demanding payload and mobility requirements set by the U.S. Army HDT program.
