Mack Defense Introduces M917A3 Heavy Dump Truck at Showcase for Commerce

05-23-2019 

Mack Defense will display its M917A3 heavy dump truck (HDT) with an armored cab for the first time in public during this year’s 29th annual Showcase for Commerce, a nationally renowned business and industry trade show and defense contracting exhibition May 29-31 in Johnstown, Pennsylvania. Mack Defense will be located at indoor booth No. 57, as well as outside booths V1 and V2.

“We are excited to share Mack Defense’s new M917A3 HDT to this important audience,” said David Hartzell, president of Mack Defense. “The armored cab is just one of several survivability and capability upgrades on the M917A3 HDT.”

For more than 100 years, dump trucks have been integral to supporting the evolving mission of U.S. Army personnel. The implementation of the new M917A3 HDT brings critical force modernization to the Army with reduced costs for parts and maintenance to meet the Army's changing mission.

The third-generation HDT is scheduled for rollout over the next few years to active U.S. Army and National Guard units currently equipped with older trucks. The M917A3 HDT will go to work immediately on important combat support missions overseas, as well as domestic duty in response to floods, fires and other natural disaster needs.

The M917A3 HDT builds upon the legendary performance of Mack® trucks with specific, new capabilities around payload, mobility and occupant survivability. The new armored cab is a key survivability feature that exceeds the Army’s blast requirements, while maintaining all interior features of the commercially available Mack Granite® model, on which it is based.
