Mack Defense has announced that the US Army and the US Army Reserve have ordered an additional 144 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 US$296M 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
- motor pools
The Army had previously ordered 155 HDTs. These are specified with heavier-duty rear axles, all-wheel drive, increased suspension ride height and other ruggedised features. According to Mack, those HDT vehicles have all been built, and final deliveries will continue through August 2022.
