US Army, GM Defense agree to add 12,000 Infantry Squad Vehicles to fleet

GM Defense announced on Monday that the Army has expanded orders for the Infantry Squad Vehicle, or ISV, from the initial 649 to nearly 12,000.

The announcement, made at the annual exposition for the Association of the United States Army, means the service will be increasing its fleet of ISVs by roughly 1,750%.

Company President Steve duMont praised his GM Defense’s ability to deliver on the fast-paced needs of the Army, touting the company’s ability to meet the demands of the “modern defense landscape” with “advanced capability, rapid fielding and sustainable scale.”

“By transferring GM’s world-class engineering, supply chain and manufacturing scale directly to the service member, we are transforming customer needs into mission-ready capability faster than ever before,” duMont said.

To illustrate the pace at which it operates, the company referenced how it delivered PAC-3 Missile Segment Enhancement housing components to Lockheed Martin in just 22 days. The company said the feat shows how “GM’s advanced casting and precision-fabrication capabilities can immediately scale” to deliver critical components.

Ahead of development of the ISV, GM worked closely with the Army to identify “a clear operational gap,” according to the company. It then used the information to self-fund the creation of an ISV-Utility prototype. In turn, the GM Defense delivered seven prototypes of the “highly versatile five-soldier variant” for unit-level assessments “at no cost” to the Army.

The company added that those variants will be fielded across 39 active-duty and National Guard mobile brigades.

Unlike traditional combat vehicles, the ISV does not have armor. In fact, the standard design doesn’t even have doors or windows.

The ISV and ISV-Heavy, which are modeled after GM’s Chevrolet Colorado ZR2 and Chevrolet Silverado HD 3500 ZR2, respectively, are designed to be adapted to changes on the battlefield rather than specific mission sets.

Using lessons learned from Ukraine, Army officials say the ISV will serve as a platform for newly established Mobile Brigade Combat Teams, or MBCTs, which are designed to quickly respond to evolving threats and the demands of large-scale combat operations.

At AUSA, GM Defense also unveiled concepts for an unmanned ground vehicle, or UGV, and an expeditionary energy storage system.

The UGV uses what the company described as “Chevrolet Silverado 3500HD dual-rear-wheel skateboard architecture” and is intended for “silent logistics and casualty evacuation.” GM Defense aims to begin testing the vehicle in 2027.

The company also showcased the EPIQ Hybrid prototype, an Army-inspired expeditionary energy storage system. According to GM Defense, the 60-kilowatt, 100-kilowatt-hour system is paired with an onboard generator designed to reduce thermal and noise signatures.
