The U.S. Marine Corps has entered the next phase of its Medium Tactical Truck (MTT) program by awarding prototype contracts to Mack Defense and ND Defense.
According to reports, Mack Defense was awarded $16 million, while ND Defense, formerly known as Navistar Defense, was awarded $17.2 million for the development of new tactical trucks that will replace the Corps’ aging Oshkosh-built fleet.
According to a Department of Defense press release, the Marine Corps is seeking vehicles that reduce fuel consumption, extend operational range, and feature a silent watch capability. Additionally, these vehicles should provide 10–30 kW of exportable power to support field equipment.
In a press release, Mack said it is building two variants based on its Granite platform: a 4×4 with a 10-foot cargo bed and a 6×6 with a 20-foot bed.
Mack said its prototypes incorporate significant technological advancements in driver safety and operational capability, including advanced driver assistance features such as collision avoidance, blind-spot detection, and vehicle dynamic control systems with enhanced traction control and anti-lock brakes.
Additionally, the vehicles feature hybrid-electric technology that improves fuel efficiency while providing critical tactical advantages like silent watch capability.
“These prototypes represent the next generation of purpose-built, specialty vehicles for the Marine Corps,” David Hartzell, president of Mack Defense said.
Meanwhile, ND Defense said it will deliver two vehicle prototypes based on its Atlas platform.
“We are committed to ensuring that the Marine Corps’ future logistic vehicle fleet meets their Force Design goals of being more agile, efficient, and technologically advanced,” said ND Defense chief executive officer Imtiaz Uddin.
Mack said construction of its prototypes will begin in the second half of 2025, with completion targeted for early fall. Following assembly, the vehicles will undergo performance testing in the first half of 2026 before delivery to the Marine Corps.
Meanwhile, ND Defense stated its prototypes are expected to be completed within 18 months.
