GM Defense LLC

GM Defense LLC, a General Motors subsidiary based in Detroit, Michigan, manufactures light tactical vehicles and armored government vehicles as a prime contractor on full-and-open federal procurements without SBA designations, holding primary authority across the Department of the Army, the Department of State's Bureau of Diplomatic Security, and select other defense agencies. The company operates almost entirely as a prime (98% of awards) and competes exclusively in full-and-open markets; it does not hold 8(a), HUBZone, SDVOSB, or other socioeconomic set-aside certifications.

GM Defense's customer concentration is pronounced and reflects a dual-track strategy: the Department of the Army dominates by both award count and dollar volume, with 88 awards totaling $799.9 million combined potential value, while the Department of State's Bureau of Diplomatic Security represents the second-largest customer by dollar magnitude at $497.9 million combined potential value across 10 awards. Together, these two agencies account for roughly 87% of the award count and approximately 98% of all potential value across the vendor's federal portfolio. The Army concentration reflects GM Defense's anchor position in the Infantry Squad Vehicle (ISV) program, a light tactical mobility platform based on Chevrolet commercial platforms; the State Department relationship centers on large armored Suburban SUVs for diplomatic protection operations.

The Army work is dominated by task orders under a single-award IDIQ (W56HZV20D0066) valued at $214 million, running through June 2028, which has generated 99 task orders totaling $589.7 million in combined potential value. This vehicle covers procurement of approximately 2,065 Infantry Squad Vehicles and associated services, including armor kits, winch kits, systems engineering, program management, integrated product support, and field service representative support across ISV variants (utility, electric, weapons-integrated). Representative Army delivery orders include a $99.9 million award (September 2025) for 829 ISVs with anti-lock braking system and electronic stability control kits, a $105.9 million award (June 2026) for 691 ISVs and winch kits, and a $44.9 million award (February 2025) for 287 ISVs with associated kits. The State Department relationship anchors a second single-award IDIQ (19AQMM23D0103) valued at $300 million, running through September 2033, which has generated 8 task orders totaling $159.5 million and covers large armored SUV production and engineering services. Recent State Department delivery orders include a $53 million award (September 2024), a $42.9 million award (September 2025), and a $17.5 million award (August 2026), all for large armored SUV production with Detroit manufacturing.

GM Defense holds three additional IDV vehicles with smaller dollar exposure: a $18 million sole-source IDIQ (January 2025, ACC Warren) for Heavy-Duty Sport Utility Vehicles running through December 2029; a $8.1 million single-award IDIQ (June 2026, Army) for Suburban Shield vehicles running through June 2031; a $6.4 million single-award IDIQ (May 2026, Army) for ISV comprehensive maintenance, fielding support, test, and retrofit through April 2028; and an $8.4 million Other Transaction Agreement (June 2023, Marine Corps) under the STEEP (Science and Technology for Expeditionary Platforms and Environmental) framework. These vehicles are narrower in scope and ordering activity compared to the two primary IDIQs.

Activity has remained relatively stable year-over-year, ranging from 16 to 28 awards annually over the past five years (FY2022–FY2026), with 28 awards in FY2025 and 16 in FY2026 to date. The recompete cliff is substantial: 17 awards with ultimate completion dates in the next twenty-four months carry combined potential value of $419 million, representing significant recompete exposure. The $214 million Army ISV IDIQ is the primary driver of this near-term cliff risk.

From a Service Contract Inventory perspective, GM Defense reported minimal service-contract activity: $1.8 million in invoiced revenue in FY2024 across 12.6 contract-level FTEs, with no reportable SCI activity in FY2022, FY2023, or FY2025. The median government-paid hourly rate derived from FY2024 invoicing was $66.98/hr. This sparse SCI footprint reflects GM Defense's business model: the company's federal revenue is dominated by tangible goods (vehicle procurement and kits) rather than labor-hour services, so SCI (which captures only service contracts above $150,000) does not represent the company's true federal revenue scale. GM Defense reported zero sub-hours across its SCI prime contracts, indicating in-house delivery of services captured by SCI.

On the subcontracting side, GM Defense operates almost exclusively as a prime (98% of awards). The three sub-awards in the source reflect niche roles: one sub to Oshkosh Defense under a Navy Marine Ship Interdiction System contract (June 2026), one sub to Booz Allen Hamilton under an Engineering Development Integration and Technology-Based Solutions contract (February 2026), and one historical sub to Oshkosh Defense under a predecessor ISV sustainment contract (February 2023). This thin sub footprint signals that GM Defense builds its own delivery teams rather than relying on subcontractors for core manufacturing and integration work.

GM Defense's award portfolio is narrowly concentrated in vehicle manufacturing: NAICS 336992 (Light Truck and Utility Vehicle Manufacturing) characterizes 100 of 127 awards, with secondary exposure in NAICS 336991 (Military Armored Vehicle, Tank, and Tank Component Manufacturing) across 13 awards. PSC coding is similarly focused: PSC 2320 (Combat, Assault, and Tactical Vehicles, Wheeled) covers 90 awards, followed by PSC 1650 (Passenger Motor Vehicles) across 12 awards. This narrow capability footprint and customer concentration (two agencies representing 98% of potential value) positions GM Defense as a specialized platform player anchored to two strategic vehicle programs rather than a diversified defense prime.
