Mack Defense receives $47M in federal funding
Stacy Wescoe//June 22, 2026//
Mack Defense has received $47 million in federal funding to continue building the M917A3 Heavy Dump Truck at its Allentown facility.
U.S. Rep. Ryan Mackenzie made the announcement Friday during an event at the facility.
The funding is part of the new five-year contract awarded in June 2025 to Mack Defense for up to 450 trucks, with a total contract value of up to $221.8 million.
The appropriation, part of the 2026 Department of Defense Appropriations Act, allows the local production line to maintain operations and meet the U.S. military’s heavy logistics needs.
“Military readiness depends on reliable logistical support that enables our servicemembers to get the job done. Nobody is better prepared to deliver it than workers right here in the Lehigh Valley,” Mackenzie said. “That’s why I worked to ensure that local employees at Mack Defense can continue to meet the logistical demands of our armed forces with the help of a $47 million appropriation. We’re looking forward to seeing these highly skilled workers continue delivering the top-quality vehicles that help keep our country safe.”
The HDT, based off the commercially available Mack Granite, is used in construction and upkeep of infrastructure assets, including airfields, roadways, landing strips, supply facilities and motor pools.
According to Mack, they’re spec’d with heavier-duty rear axles, all-wheel drive, increased suspension ride height and other ruggedized features to meet the requirements of the U.S. military.
“With this funding now in place, our team in Allentown can keep building the M917A3 and supporting the soldiers who rely on it,” said David Hartzell, president of Mack Defense.
