American Rheinmetall and Harbinger Partner to Develop Hybrid-Electric UGVs for U.S. Defense Programs

American Rheinmetall and Harbinger announced on May 27 that they have entered into a strategic partnership to develop a new family of uncrewed ground vehicles (UGVs) for the United States Department of War. The collaboration combines American Rheinmetall’s expertise in combat vehicle integration with Harbinger’s commercially developed hybrid-electric chassis platform. Through this initiative, both companies aim to address evolving military mobility requirements while leveraging technologies that can support both defense and commercial applications.

The partnership is focused on pursuing existing and future U.S. Army opportunities involving autonomous tactical wheeled vehicles, contested-logistics resupply missions, and manned-unmanned teaming operations. These programs increasingly require platforms capable of operating in demanding environments with enhanced autonomy, operational flexibility, and reduced logistical burdens. By integrating proven vehicle technologies with modern electrified architectures, the companies seek to deliver solutions that align with emerging military operational needs.

Harbinger’s platform has been engineered and developed internally at the company’s California headquarters. The chassis features a drive-by-wire hybrid-electric architecture paired with a range-extended powertrain. This design supports silent watch capabilities by reducing both thermal and acoustic signatures, an important requirement for military operations where stealth and energy efficiency are critical. The system combines an electric drivetrain with a gasoline-powered range extender that can recharge the battery when additional operational endurance is required.

The hybrid-electric chassis is intended to provide flexibility across multiple mission profiles. Reduced noise generation and lower thermal output can improve survivability in tactical environments, while the range-extending capability allows the vehicle to sustain operations beyond the limitations of a conventional battery-electric platform. These characteristics make the technology suitable for autonomous logistics missions, reconnaissance support, and other applications requiring extended operational availability.

Harbinger will provide its dual-use hybrid-electric chassis in two distinct configurations. One version will be configured as a commercial delivery van, while the second will serve as an uncrewed military ground vehicle designed specifically for American Rheinmetall’s defense programs. This approach enables both companies to leverage shared technology foundations while tailoring vehicle capabilities to the requirements of different end users and operational environments.

Joint demonstrations of the new platform are expected to take place during the summer. These demonstrations are anticipated to showcase the integration of American Rheinmetall’s defense vehicle expertise with Harbinger’s electrified chassis technology, providing an opportunity to validate performance, autonomy capabilities, and mission suitability for future military applications.
