Mack Defense Secures Initial Order for M917A3 Heavy Dump Trucks
On October 7, 2025, Mack Defense announced its receipt of an initial procurement order for 86 M917A3 Heavy Dump Trucks (HDTs) from the United States Army. This order is part of a comprehensive five-year contract, awarded on June 24, 2025, which has the potential to encompass up to 450 trucks valued at approximately $221.8 million (EUR 190.6 million).
Background of the Contract
This initial order represents the first batch produced under the new contract, following the successful conclusion of Mack Defense’s previous seven-year agreement established in 2018. Funding for these vehicles has been allocated from the Department of Defense’s 2025 budget. Mack Defense interprets this commitment as indicative of ongoing federal investment in tactical vehicle modernization and support for the U.S. industrial base.
Operational Versatility
The M917A3 Heavy Dump Trucks are designed for multifaceted applications in various operational terrains. Key roles include:
- Infrastructure Development: Support for airfields, roadways, and landing strips.
- Logistical Support: Assistance in establishing supply facilities and motor pools.
This capability underscores the importance of versatile engineering assets within military operations.
Technical Specifications
The M917A3 is an upgraded version based on the Mack Granite commercial model, rigorously tailored to meet the specific requirements of the U.S. Army. Notable enhancements consist of:
- All-Wheel Drive: Improved traction and mobility.
- Reinforced Rear Axles: Better load-bearing capacity.
- Increased Ground Clearance: Adaptation for rugged environments.

- Anti-Lock Braking System (ABS): Advanced safety measures.
These modifications collectively improve handling, performance, and operational flexibility.
Production and Quality Assurance
All M917A3 vehicles are assembled at the Mack Experience Center (MEC) located in Allentown, Pennsylvania. Mack Defense established a dedicated production line there in 2021, following a $6.5 million investment to modernize the facility. The MEC has successfully passed stringent governmental inspections, thereby assuring product quality and reliability, which are paramount for the U.S. military’s operational needs.
Commitment to Military Readiness
Mack Defense affirms that the M917A3 serves as an essential asset for the Army Engineer Regiment, delivering the durability and mobility required for complex missions in diverse environments.
Derik Beck, the senior director of sales, business development, and marketing at Mack Defense, articulated the company’s dedication:
“This new order reinforces the critical role the M917A3 plays in sustainment missions and reflects the trust the Army has placed in our team and American manufacturing capabilities.”
By utilizing a commercially established platform such as the Mack Granite, the Army can capitalize on a resilient supply chain and sustained lifecycle support across extensive operational realms.
Conclusion
As production commenced in March 2021, the new order not only fulfills existing contract obligations but also enables Mack Defense to diversify its vehicle offerings. This strategic initiative is integral to enhancing the U.S. military’s tactical capabilities while bolstering local manufacturing efforts. Mack Defense’s focus on high-performance equipment aligns with the evolving needs of American defense operations, ensuring preparedness for future challenges.
