Mack Defense Receives Order for 144 Additional Trucks for the U.S. Army M917A3 Heavy Dump Truck Program

Mack Defense announced today that the U.S. Army and the U.S. Army Reserve have ordered an additional 144 Mack Defense M917A3 Heavy Dump Trucks (HDTs).

The additional vehicles, based on the commercially available Mack® Granite® model, are part of the previously announced firm-fixed price $296 million contract to be fulfilled over seven years that the Army awarded Mack Defense in 2018. The HDTs are a key component in construction and maintenance missions for infrastructure assets, such as airfields, roadways, landing strips, supply facilities and motor pools.

We are proud to maintain our production operation which was created for the U.S. Army M917A3 HDT program, and we are extremely proud that our Mack Defense HDT vehicles, which have been fielded, are meeting and exceeding expectations.

Mack Defense remains committed to producing vehicles for the U.S. armed forces based on modified versions of our industry-leading Mack vehicles providing the latest technologies and best value while meeting the military’s demanding requirements.

David Hartzell, president of Mack Defense

The Army previously had ordered 155 HDTs, which are spec’d with heavier-duty rear axles, all-wheel drive, increased suspension ride height and other ruggedized features to meet the unique requirements of the Army. Those HDT vehicles have all been built, and final deliveries will continue through August 2022.

The Mack Granite HDT model is a modern truck equipped with modern technology, such as ABS and other active safety systems. The Granite model is user-friendly, comfortable and safer to operate compared with other past models used by the Army, which is key to the Army’s investment in the new HDTs, Hartzell said. The Granite HDTs and the production line at the Mack Experience Center in Allentown, Pennsylvania, were both inspected by the government quality auditors to ensure both met expectations.

Production of the HDTs at the MEC began in Q1 2021, following an investment of $6.5 million to create a dedicated HDT production line at the facility. The production line helps fulfill the M917A3 contract, while allowing Mack Defense to produce other vehicle variants.

The production line in the MEC is in Mack’s former Customer Adaptation Center, where vehicle modifications occurred. The Customer Adaptation Center has since moved to Mack’s Lehigh Valley Operations (LVO) in Macungie, Pennsylvania, where all Mack Class 8 vehicles for North America and export are assembled. Previously, non-armored HDT vehicles began production at LVO and were then transported to the MEC, where final assembly, including adding the dump body, occurred.
