In late July 2026, the U.S. Army announced an 18‑month contract to American Rheinmetall under Project Sustainment for plug‑in hybrid, autonomous uncrewed ground vehicles (UGVs). The effort, built on Harbinger Motors’ hybrid platform, involved partners Forterra and Primordial Labs and aimed to provide voice‑controlled, mission‑aware logistics support for forward troops. A few days later, the contract details were clarified: the award spans two years, calls for four UGVs capable of carrying up to 18,000 lb over more than 500 mi. The vehicles will integrate autonomy technology from Forterra and a natural‑language interface from Primordial Labs, reinforcing the Army’s broader modernization and tactical sustainment goals. By late August 2026, reports indicated that this project is part of a larger strategic shift by the U.S. Army toward electric and hybrid combat technology. This transition aims to address specific battlefield needs, including low acoustic and thermal signatures, battery safety, and navigation across extreme terrain. The push for unmanned logistics is also being influenced by observations from the conflict in Ukraine, where unmanned systems have demonstrated high effectiveness in both aerial and ground operations.
