GM Defense is the military product subsidiary of General Motors, headquartered in Concord, North Carolina. It focuses on defense industry needs with hydrogen fuel cell and other advanced mobility technologies.[2] GM Defense projects include SURUS (Silent Utility Rover Universal Superstructure), an autonomous modular platform joint project with the United States Army.[3]
ZH2 are modified Chevrolet medium and full size pickups modified for military needs. The ZH2, fitted with a hydrogen fuel cell and electric drive, has a stealthy drive system which produces a very low smoke, noise, odor and thermal signature. This allows soldiers to conduct silent watch and silent mobility missions on the battlefield.[4]
General Motors, the Office of Naval Research and the U.S. Naval Research Laboratory are cooperating to incorporate automotive hydrogen fuel cell systems into the next generation of Navy unmanned undersea vehicles, or UUVs. Hydrogen fuel cell technology could augment ships and subs on patrol.[5]
Air-transportable high-speed, light utility vehicle based on the Chevrolet Colorado ZR2 selected by the U.S. Army in June 2020.[7]
Chevrolet Colorado ZH2
Military truck
Extreme off-road-capable fuel-cell-powered electric vehicle. Based on the Chevrolet Colorado. The Colorado ZH2 is the product of a joint venture between GM and TARDEC—the U.S. Army’s Tank Automotive Research, Development, and Engineering Center.[8]
SURUS - Silent Utility Rover Universal Super Structure
Modular military platform
GM-U.S. Army collaboration on a modular experimental light- and medium-duty fuel-cell truck platform.[9]
Autonomous fuel cell vehicle with highly modular and adaptable superstructure. Powered by Hydrotec and JOULETEC propulsion systems.
Chevrolet Silverado ZH2
Military truck
GM has developed a new 'ZH2' hydrogen fuel cell-powered electric truck, with a next-generation engine and a Chevrolet Silverado chassis. The Silverado ZH2 can output up to 100 kW of power.[10]
UUV
Unmanned Underwater Vehicle
A partnership with General Motors and the Office of Naval Research and the U.S. Naval Research Laboratory partnership for automotive hydrogen fuel cell systems into the next generation of Navy unmanned undersea vehicles, or UUVs.[11] The UUV leverages GM Hydrotec fuel cell technology common with the Colorado ZH2.[12]
With the sale to General Dynamics, only the Stryker product lines are still in production. The M54 truck is no longer in production. MILCOT was transitioned to the US Army's COMBATT program.
