GM Defense Locks In $18.8M Army Order for 121 Infantry Squad Vehicles

The U.S. Army has awarded GM Defense a firm-fixed-price contract worth $18.8 million to deliver 121 Infantry Squad Vehicles (ISVs), along with anti-lock brake system (ABS) and electronic stability control (ESC) kits and vehicle storage covers.

The award, announced Wednesday, comes through the Army Contracting Command – Detroit Arsenal following a competitive solicitation that drew three bids. The contract runs through April 30, 2027, and falls under a broader indefinite-delivery/indefinite-quantity (IDIQ) contract vehicle with a ceiling of approximately $458.4 million.

A Proven Platform

The ISV is a lightweight, nine-passenger tactical transport built on the Chevrolet Colorado ZR2 chassis — a platform already well-known in the commercial off-road truck segment. What sets it apart from purpose-built military designs is its extensive use of commercial off-the-shelf (COTS) components: roughly 90 percent of its parts come from the Chevrolet Performance parts catalog, which GM Defense says simplifies maintenance, reduces logistics overhead, and keeps per-unit costs down.

Under the hood sits a GM Duramax 2.8-liter turbo-diesel I4 engine paired with a Hydro-Matic 6L50 six-speed transmission and an AutoTrac two-speed transfer case with a 2.62 low-range gear. The Dana M190 (front) and M220 (rear) axles — borrowed from the ZR2 package — come with electronic locking differentials, giving the ISV serious off-road capability straight from the factory floor.

The vehicle also features a Roll Over Protection System (ROPS) as standard safety equipment, now supplemented by the ABS and ESC kits included in this latest order.

Air-Deployable by Design

One of the ISV's key selling points is its expeditionary flexibility. The vehicle is sized and engineered for rapid deployment by both fixed-wing and rotary-wing aircraft:

  • Fixed-wing: C-17 Globemaster III, C-130 Hercules, A-400M Atlas (low-velocity airdrop capable)
  • Rotary-wing: CH-47 Chinook (internal load), CH-53E/K Super/King Stallion (internal load), UH-60 Black Hawk (sling-load)

This air-transportability makes the ISV a natural fit for light infantry, airborne, and special operations units that need to move a squad and its gear quickly without bringing in heavy logistics equipment.

Full-Rate Production Well Underway

This is not GM Defense's first ISV rodeo. The Army awarded the company two firm-fixed-price contracts totaling approximately $222.9 million in 2020 for ISV manufacturing, installation kits, hardware, and logistics support. In April 2023, the program achieved full-rate production approval, signaling that the ISV had passed its operational testing milestones and was ready for sustained volume manufacturing.

With this latest order of 121 units, the total ISV fleet continues to grow as the Army pushes forward with its "Army 2030" modernization roadmap. The ISV fills a specific niche between the heavy JLTV and unprotected light tactical vehicles — fast, agile, and air-portable, yet capable of carrying a full nine-soldier infantry squad plus equipment.

What It Means for the Defense Mobility Market

For the broader defense mobility sector, this contract reaffirms the military's appetite for commercially derived tactical platforms. The COTS approach — borrowing proven automotive architecture from Chevrolet's parts bin — keeps the ISV affordable and maintainable compared to bespoke military designs. It also opens the door for other automotive OEMs with off-road expertise to compete for similar programs, especially as the Army looks for lighter, more deployable alternatives to its heavier armored fleets.

The ISV program's steady order cadence — from initial 2020 awards through full-rate production to today's $18.8M order — suggests the Army sees real value in keeping a commercially rooted, air-deployable squad carrier in the mix alongside heavier platforms.
