General Motors’ defense unit GM Defense, LLC has been awarded a $1 million contract from the U.S. Army. The contract is for GM to further develop a new Infantry Squad Vehicle (ISV) for further testing.

The Army has already been conducting field tests of the ISV at Fort Bragg, North Carolina. Such field tests have led the Army to decide to issue a contract to GM Defense to build two ISV prototypes for further evaluation this fall.

GM Defense has leveraged the Chevrolet Colorado’s architecture and components from the production ZR2 as the basis for the ISV. These production components have merged with other off-the-shelf components to simplify engineering. Even Colorado’s 2.8-liter Duramax diesel is found under the hood.

Despite the production components, the ISV looks nothing like the Colorado. The Army has stringent requirements for the ISV, including that it must be light enough to be sling-loaded from a UH-60 Blackhawk helicopter, compact enough to fit inside a CH-47 Chinook helicopter and versatile enough to carry up to nine soldiers.

“Our ISV entry is a fully-integrated platform that leverages decades of GM’s engineering, manufacturing and quality expertise at scale to provide the most cost-efficient, reliable and effective answer possible to meet and exceed the Army’s demanding requirements,” said GM Defense President David Albritton. “We’re very proud of the opportunity to move forward in this competition and continue our development of a vehicle that will enable Army units to move around the battlefield with greater ease and reliability.”

The Army plans to acquire approximately 650 ISV units as early as 2020.
