Ford and General Motors are finding an increasingly familiar-looking doorway into an unfamiliar market: military vehicles built from the trucks they already know how to engineer, manufacture and service. As civilian auto demand becomes less predictable and traditional Western manufacturers confront excess capacity, defence spending is creating another potential outlet for industrial expertise that might otherwise sit underused.
The shift is not a wholesale conversion of Detroit into a defence industry. Military volumes remain tiny compared with consumer vehicle production. Instead, Ford and GM are pursuing selective opportunities where commercial pickups, existing components, established suppliers and large service networks can be adapted for government customers. Recent U.S. Army prototype work, a major British vehicle competition and GM Defense’s growing contract book show why that strategy is attracting attention.
Military Work Is Moving Closer to Detroit’s Core Business
The appeal of defence work becomes easier to understand when the products involved look less like specialized armoured vehicles and more like heavily modified commercial trucks. Ford, GM and Jaguar Land Rover are among the companies pursuing a British Ministry of Defence vehicle program initially covering about 3,000 vehicles and valued at roughly £900 million. Ford is offering a version of the Ranger, while GM’s effort includes Chevrolet Silverado pickups adapted for military requirements. That lets automakers start with platforms, engines, components and production knowledge they already possess rather than creating an entirely new military vehicle from scratch.
That approach fits a much larger increase in defence spending. The British government’s 2026 Defence Investment Plan lays out approximately £298 billion in Ministry of Defence spending over four years. Vehicle contracts represent only a small slice of that amount, but the direction of spending matters to manufacturers searching for new customers. A commercial pickup that already has years of development behind it can provide a relatively practical foundation for military mobility, particularly where buyers value payload, durability, serviceability and parts availability more than a completely bespoke design.
GM Already Has Proof That a Civilian Truck Can Become a Military Program
General Motors has moved beyond simply discussing military vehicles. Its GM Defense subsidiary already builds the U.S. Army’s Infantry Squad Vehicle, a lightweight nine-passenger platform derived from the Chevrolet Colorado ZR2. When the Army selected GM Defense in 2020, the initial production contract was worth about $214.3 million for 649 vehicles. The Army said roughly 90% of the vehicle’s parts were commercial off-the-shelf components, demonstrating how closely a military platform can remain connected to a mainstream automotive supply base.
The program has expanded substantially since that first order. On September 21, 2026, GM Defense received a $697.7 million contract modification covering engineering change proposals for the Infantry Squad Vehicle Utility and its winch kit. The action brought the cumulative face value of that contract to about $915.6 million, with completion estimated for June 2028. For GM, that makes defence more than an experimental sideline. It also illustrates the attraction of adapting proven automotive hardware: technicians, suppliers and production planners are working with technology that has substantial commercial roots rather than supporting a vehicle created entirely outside the company’s normal manufacturing ecosystem.
Ford Is Entering Through a New Army Truck Competition
Ford’s latest military effort follows a similar playbook. The U.S. Army awarded prototype agreements in June 2026 to Ford, GM Defense and BC Customs for a new Infantry Squad Vehicle-Heavy, or ISV-H. Each competitor is expected to deliver three prototypes, with the first vehicles scheduled for March 2027. Army requirements outlined during the competition include seating for six, significant payload capacity, trailer-towing capability and enough onboard electrical power to support increasingly demanding battlefield equipment.
Ford CEO Jim Farley subsequently said the company’s three prototypes would be based on the Super Duty platform. That matters because Super Duty is already designed around customers who regularly demand high payloads, towing capacity, durability and broad access to replacement parts. The Army’s fiscal 2027 planning documents put the approved acquisition objective for the ISV-H at 606 vehicles, although prototype participation does not guarantee Ford a production award. Even so, the competition gives Ford a relatively low-risk way to test whether one of its strongest commercial franchises can translate into recurring military business without creating a standalone defence vehicle division on the scale of established contractors.
Slower Detroit Sales Do Not Mean the Entire Auto Market Is Collapsing
The backdrop requires some care. Ford and GM are facing softer U.S. sales and market-share pressure in 2026, but the broader new-vehicle market has proved stronger than many analysts expected. Cox Automotive’s September forecast projected Ford sales through the first three quarters to fall 8.8% from a year earlier, reducing its U.S. share to about 12.5%. GM was projected to remain the country’s largest seller while posting a 6.2% year-to-date decline, with market share falling to 16.7% from 17.4%.
At the same time, Cox raised its full-year U.S. new-vehicle forecast from 15.8 million to 16.1 million units. September sales volume itself was expected to rise 6.5% year over year, even as the seasonally adjusted annual selling rate eased to approximately 16.3 million from 16.8 million in August. The pressure, therefore, is uneven. Asian manufacturers have been gaining share, particularly as buyers show greater interest in hybrids and fuel-efficient vehicles. Defence work offers Ford and GM another revenue stream during that shift, but it is not a response to an industry in free fall.
Britain Shows Why Existing Pickups Are Attractive to Military Buyers
The British competition provides perhaps the clearest illustration of what automakers hope to sell. Rather than competing entirely through clean-sheet tactical vehicles, Ford, GM and JLR are putting established commercial products at the centre of their bids. Ford’s Ranger is already a widely produced global pickup. GM’s bid includes two retrofitted Silverado variants, while JLR is offering its Defender. Each company can therefore bring years of engineering, production experience and supplier relationships into a procurement process normally dominated by dedicated defence manufacturers.
That does not mean a dealership pickup can simply be painted military green and sent into service. Military customers can require different communications equipment, electrical systems, payload configurations, protection, recovery hardware and mission-specific accessories. The advantage is that the underlying vehicle architecture has already been developed at automotive scale. GM Defense executives have argued that capable commercial trucks require a more manageable level of adaptation than starting from zero. For governments trying to expand fleets while controlling cost and delivery time, commercial foundations can be appealing precisely because the most basic engineering and supply-chain work has already been done.
Underused Auto Plants May Be More Valuable to Defence Companies Than Automakers
A second part of the trend involves factories rather than vehicles. Car assembly plants are enormous, capital-intensive operations designed to repeat a specific sequence thousands of times. That can make direct conversion to lower-volume defence manufacturing less straightforward than it initially sounds. Analysts interviewed by Reuters suggested that selling surplus automotive facilities to specialist defence companies may sometimes provide a clearer benefit than trying to make military components on lines built for mass-market cars.
Recent deals show how that could work. Stellantis has signed a memorandum with Canadian armoured-vehicle manufacturer Roshel outlining a possible sale of its idled Brampton Assembly plant in Ontario, where Roshel has said it wants to create a defence-manufacturing centre. In Germany, Volkswagen reached a preliminary agreement involving its Osnabrück factory, where passenger-vehicle production is scheduled to end in 2027. The proposed defence project could preserve roughly 1,400 of the site’s approximately 1,800 jobs, according to labour officials. Neither case involves Ford or GM directly, but both demonstrate how surplus automotive property, equipment and skilled workforces are becoming attractive to an expanding defence sector.
Auto Suppliers Could Make the Transition More Easily Than Full Assembly Plants
The opportunity may be even more practical for suppliers. Component factories generally operate at a smaller scale than final vehicle assembly plants and often contain welding, machining, electronics or fabrication equipment that can be redirected without redesigning an entire production system. French automotive supplier Forvia offers a concrete example. In June, it signed an agreement to transfer its Augsburg, Germany, operation to General Dynamics European Land Systems, a military-vehicle manufacturer.
The planned transaction includes approximately 300 employees, subject to regulatory and consultation requirements. Forvia and General Dynamics also developed a nine-month training program intended to help workers move into defence-related production while building on existing automotive manufacturing skills. General Dynamics said it plans to develop the facility into a major German vehicle site and a centre associated with its EAGLE tactical vehicle family. For workers accustomed to producing exhaust systems and automotive components, that kind of transition is less about abandoning manufacturing experience than applying it to a new customer. It also shows why labour skills can be almost as valuable as the physical factory when defence contractors need capacity quickly.
GM’s Growth Targets Show Both the Potential and the Limits
GM Defense expects revenue to approach $700 million in 2026 and has told investors it is targeting annual revenue growth of more than 30% over the next several years, along with double-digit margins. Those figures make defence one of GM’s more visible emerging businesses. The nearly $700 million Army contract modification announced in September further strengthens the idea that military mobility can develop into a meaningful specialist operation inside a much larger automaker.
Scale, however, puts the opportunity in perspective. General Motors reported $185.0 billion in total net sales and revenue for 2025. Reuters calculated that even if GM Defense grows to roughly $1.5 billion in annual revenue by 2029, it would still represent less than 1% of GM’s 2025 group revenue. Ford faces the same basic arithmetic: a few hundred or even a few thousand military trucks cannot replace demand for millions of civilian vehicles. Defence can create profitable contracts, keep engineering teams occupied and potentially support portions of an industrial footprint, but the fortunes of both companies will continue to depend overwhelmingly on how successfully they compete for ordinary vehicle buyers.
Defence Looks More Like a Hedge Than a Replacement for Auto Sales
The emerging strategy is therefore more measured than the headline image of auto factories suddenly turning into military plants. Ford is using Super Duty expertise to compete for an Army vehicle. GM is expanding a defence operation built around commercial Chevrolet platforms. In Britain, both companies are pursuing a military tender with vehicles closely related to pickups already sold to civilian and commercial customers. Elsewhere, underused automotive properties and supplier operations are being transferred to companies that can put their machinery and skilled workers to different uses.
That can still matter enormously at the local level. A defence contract that looks small beside a global automaker’s revenue can support engineering teams, suppliers and manufacturing jobs that might otherwise be vulnerable when vehicle programs shrink or disappear. But military work is unlikely to solve the industry’s larger problems with market share, consumer affordability, changing powertrain preferences or excess production capacity by itself. For Ford and GM, the more realistic opportunity is selective diversification—using capabilities developed for civilian trucks wherever military customers have a need for the same combination of durability, scale and manufacturing experience.
