In January 2023, Mack Defense was awarded a contract to design, build, and deliver trucks for the prototype and testing phase of the U.S. Army’s Common Tactical Truck (CTT) program.

The U.S. Army is modernizing and replacing ~35,000 heavy tactical trucks.
These vehicles perform a wide range of combat logistics, support, and service missions.
Mack Defense was chosen to develop prototypes to help define the Army’s next-generation truck requirements.

Mack Defense Solution

Our CTT prototypes are built on a modern, scalable, commercial-based platform with enhancements to meet Army requirements:

Advanced safety technologies
Increased off-road mobility 6×4
Enhanced cybersecurity
Open systems architecture for upgrades
Improved fuel efficiency
Commonality across variants for easier sustainment

Prototype Vehicles

Mack Defense delivered three prototype trucks for Army evaluation at Aberdeen Proving Ground:

On-Road Tractor
Off-Road Tractor
Load-Handling System (LHS) Truck

Each prototype was based on proven commercial vehicle platforms and adapted to meet strict CTT requirements.

Hybrid Electric Technology

All three prototypes included high-voltage hybrid electric systems.

Evaluated for:

Exportable power capability
Fuel demand reduction

Testing & Validation

Vehicles tested for performance, efficiency, and durability.
Prototype phase reaffirms Mack Defense’s proven ability to adapt commercial products and technologies to meet demanding military standards.
