American Rheinmetall Vehicles and GM Defense have won a contract for the first phase of the U.S. Army’s Common Tactical Truck (CTT) Program. This multi-phased program is aimed at replacing the Army’s family of heavy tactical trucks with production of up to 40,000 trucks valued at up to $14 billion.

The two defense companies formed a collaboration in 2022 to compete in the program to deliver a tactical truck with advanced driver assistance systems (ADAS) for safety, increased off-road mobility, cybersecurity, machine learning, artificial intelligence, improved survivability and fuel efficiency, among other emerging technologies. This resulte in the HX3 Common Tactical Truck (HX3-CTT).

The HX3-CTT next-generation system has enhanced on and off road mobility, integrated survivability, and an open digital architecture supporting ADAS and enabled for autonomous vehicle operation. Combined with the open architecture, the commercial backbone of the HX3-CTT is meant to support modernization and allow for rapid increases in capability as technologies mature.

The HX3-CTT provides a basis for optimized lifecycle costs and service support to the Army.

HX3 Common Tactical Truck

The HX3-CTT features an interchangeable protected cab design, ADAS, and drive by wire operation. The new open systems electrical architecture allows for integration of leader-follower, tele-operation, and fully autonomous capabilities that focus on protecting soldiers. 

Common platforms and parts to support a family of vehicles

The HX3-CTT allows for modularity across variants, including cargo, load handling systems, tankers, and line haul tractors. With an HX family that can scale from 4x4 to 10x10, the HX is designed to meet any military need.

Commerciality in its DNA

The HX3-CTT leverages best-in-class advances in commercial truck technology, safety, fuel efficiency, and emissions reduction. Ruggedized for the stresses of military service, the HX family provides an “off the shelf” capability. This commercial backbone reduces obsolescence risk/cost, expands parts availability and reduces sustainment demands.

Allied interoperability

The HX family of trucks have been sold to 20 customers globally including an active allied user group consisting of United Kingdom, Australia, New Zealand, Germany, Austria, Norway, Sweden, and Denmark, creating common global supply chains, training opportunities, and integrated operations among key allies operating around the world.
