GM Defense LLC

GM Defense LLC, a General Motors subsidiary, manufactures light tactical vehicles and armored government vehicles as a prime contractor delivering full-and-open (no set-aside) products to the Department of the Army, the Department of State, and other federal agencies. The company operates from Detroit, Michigan, and competes predominantly under unrestricted procurements, without SBA designations.

GM Defense's core capability is the Infantry Squad Vehicle (ISV), a light tactical mobility platform based on Chevrolet commercial platforms, along with variant ISV configurations including utility, electric, and weapons-integrated versions. The company also manufactures heavy-duty armored sport utility vehicles for the Department of State's Bureau of Diplomatic Security and provides systems engineering, program management, integrated product support, and field service representative support across its vehicle platforms. Representative recent work includes a $99.9 million delivery order (September 2025, Army) for 829 ISVs with anti-lock braking system/electronic stability control kits; a $53 million delivery order (September 2024, State Department Bureau of Diplomatic Security) for large armored SUVs; a $44.9 million delivery order (February 2025, Army) for 287 ISVs and associated kits; and a $16.2 million definitive contract (September 2025, U.S. Secret Service) for Chevrolet Suburban SUVs.

Customer concentration is heavily skewed toward the Department of the Army, which accounts for 83 awards and $680.1 million combined potential value (89% of awards by count and 99% of combined potential value across the top five agencies). The Department of State's Bureau of Diplomatic Security is the second-largest customer, with 8 awards worth $467.4 million combined potential value. The Department of Homeland Security's U.S. Secret Service, the Marine Corps, and the Army Acquisition Support Center round out the active customer set. This concentration reflects GM Defense's strategic focus: the ISV program anchors its Army business, while the $300 million State Department IDV for armored SUV production represents sustained diplomatic security vehicle supply.

GM Defense holds three primary parent vehicles: the $214 million Army single-award IDV (W56HZV20D0066, Infantry Squad Vehicle procurement and services, running through June 2028) with 95 task orders worth $478.7 million; the $300 million Department of State Bureau of Diplomatic Security single-award IDV (19AQMM23D0103, large armored SUV production and services, running through September 2033) with 6 task orders worth $129 million; and an $18 million Army single-award IDIQ (HDSUV procurement, January 2025–December 2029) awarded on a sole-source basis for heavy-duty sport utility vehicles. A Marine Corps Other Transaction Agreement for expeditionary technologies (STEEP framework) carries an $8.4 million ceiling with no reported recent task-order activity. All major vehicles are single-award contracts reflecting the specialized, sole-source nature of GM Defense's vehicle manufacturing and the government's reliance on the parent General Motors' production and engineering capabilities.

Recent activity has grown year over year—20 awards in 2022 to 27 in 2025—with ten awards (combined potential value $280.7 million) reaching ultimate completion within the next twenty-four months, presenting material recompete exposure for the Army ISV program and State Department armored SUV supply. The company operates as a prime in 98% of its recent portfolio (113 of 115 awards); two named sub-awards under Booz Allen Hamilton and Oshkosh Defense represent engineering and powertrain support roles, respectively. Service Contract Inventory reporting shows minimal SCI-reportable service work ($1.8 million invoiced in FY2024 across 12.6 FTEs), reflecting GM Defense's identity as a goods manufacturer and engineering integrator rather than a labor-hour service contractor.

GM Defense's product portfolio centers on NAICS 336992 (Light Truck and Utility Vehicle Manufacturing) and PSC 2320 (Combat, Assault, and Tactical Vehicles, Wheeled), with ancillary categories for armored vehicle manufacturing and trailer work. The company leverages General Motors' commercial vehicle platforms, supply chain, domestic manufacturing footprint, and automotive engineering expertise to deliver purpose-built military and government vehicles that compete on sole-source or sole-supplier grounds, avoiding the small-business set-aside market entirely.
