Mack Defense celebrates the official handover of the first five Mack® Granite® model-based M917A3 heavy dump trucks (HDT) to the U.S. Army during a ceremony at the Mack Customer Center. 

Leadership from Mack Defense presented the keys to officials with the U.S. Army in front of attendees, including several representatives of local and state-elected officials. Beginning in July, the trucks will enter up to 40 weeks of rigorous durability testing at the U.S. Army’s Aberdeen Test Center in Maryland.

“The Mack Defense M917A3 HDT embodies Mack’s core values of durability, reliability, and application excellence, and we’re confident these vehicles will exceed the U.S. Army’s rigorous testing requirements,” says David Hartzell, president of Mack Defense. “We are proud of our efforts and collaboration with the U.S. Army to deliver a truck that will serve the men and women of our armed forces for years to come.” 

The Mack Defense M917A3 HDT is based on the civilian Mack Granite model, one of the top-selling construction trucks in North America. To meet the demanding needs of the U.S. Army, Mack Defense engineers added heavier-duty rear axles, all-wheel drive, and increased suspension ride height. 

The new trucks will help increase the U.S. Army’s operational effectiveness and readiness, while supporting mobility, counter mobility, survivability, and sustainment operations for the Joint Force.
