On June 30, 2026, the U.S. Army awarded prototype development contracts for a new heavy infantry squad vehicle (the ISV-H, short for Infantry Squad Vehicle Heavy) to three companies: GM Defense, Ford, and a Utah manufacturer called BC Customs.
The awards became public on July 27. Each company will deliver three prototype vehicles for testing based on trucks they already build: GM's is derived from its Chevrolet Silverado HD, Ford's from its F-Series Super Duty.
One week before those awards, on July 20th, President Trump signed Executive Order 14415, "Securing America's Defense Supply Chains and Ensuring Domestic Acquisition of Critical Materials." The order tightens the rules defense contractors must follow when sourcing certain materials, and it applies directly to the two companies now building prototype military trucks.
In this episode, I walk through what the Army is asking Ford and GM to build, what the new executive order actually requires, and why supply chain experts say the timeline for meeting both may not be realistic.
Why the Pentagon turned to automakers
The idea of using commercial automakers to build military hardware traces back at least to April 2026, when Pentagon officials met with senior executives from Ford and General Motors to discuss whether the auto industry could help the military acquire vehicles, munitions, or other hardware more quickly and affordably than traditional defense contractors.
Those discussions came as U.S. munitions stockpiles had been drawn down by the war in Iran and continued support for Ukraine. Retired Army Major General John Ferrari, now at the American Enterprise Institute, described the shortage bluntly: the U.S. is "on borrowed time" on munitions, he said, and adversary nations know it.
The approach also matches Defense Secretary Pete Hegseth's broader procurement strategy, which favors buying commercially available components instead of developing specialized military-only systems, on the theory that commercial industry innovates and produces faster than the traditional defense industrial base.
What Executive Order 14415 requires
Defense contractors have long been restricted from buying certain materials, including magnets, tungsten, and tantalum, from China, Russia, Iran, and North Korea. When a compliant supplier genuinely doesn't exist, the law has allowed a "nonavailability waiver": essentially, permission to buy the restricted material anyway.
Executive Order 14415 makes those waivers much harder to get.
Starting on January 1, 2027, a contractor seeking a waiver must name the noncompliant supplier, document that it made exhaustive efforts to find a compliant alternative, and commit to a strict timeline for removing the restricted material from its supply chain.
Simply showing that no domestic option existed is no longer enough — the contractor has to show it is actively working, with real funding, to qualify one. White House adviser Peter Navarro summarized the shift for reporters as ending the era of companies claiming they had "tried nothing" before seeking an exception.
Beyond the waiver rules, the order also requires the Department of War to develop guidance by January 16, 2027 requiring prime contractors and their subcontractors, at every tier, to map their supply chains all the way back to raw materials.
That means submitting a complete "bill of materials" tracing every component to its origin, and vetting every supplier in that chain for financial risk, foreign ownership, and manufacturing capacity.
Penalties for noncompliance are serious: a knowing failure to follow an approved mitigation plan can be referred to the Attorney General, and False Claims Act violations carry treble damages, along with the possibility of suspension or debarment from future contracts.
Why this is hard for a truck program specifically
Supply chain experts say the timeline set by the executive order doesn't match how quickly a supply chain can change. Christopher Tang, distinguished professor emeritus of supply chains at UCLA, says the order puts many companies "in a bind." The due diligence required is difficult, and a supply chain can't shift as fast as a regulatory deadline demands.
He notes that older, simpler technology can be resourced more quickly than state-of-the-art components, which tend to rely more heavily on Chinese suppliers.
Brandon Barry, CEO of the Detroit-based vehicle cybersecurity firm Block Harbor, works directly on this kind of supplier tracing and describes identifying a part's true country of origin as a genuinely difficult, messy process, even with dedicated tools built for the purpose.
The Aerospace Industries Association, a trade group representing the aerospace and defense sector, has said it supports the goal of reducing dependence on adversarial nations, but believes the executive order's requirements will make that goal harder to reach rather than easier, largely because domestic sources for some of the covered materials don't yet exist at the scale needed.
A historical parallel, with a caveat
Ford's Willow Run plant, near Ypsilanti, Michigan, is often cited as proof that Detroit can retool for military production on short notice. At its peak during World War II, the plant built roughly one B-24 Liberator bomber per hour.
That comparison has an important caveat: Major General Ferrari points out that Willow Run's success depended on the military designing the bomber's specifications around machinery Ford already had, rather than asking Ford to acquire new equipment. He argues today's program faces the same constraint (commercial truck manufacturers aren't going to invest in new tooling on a defense-contract timeline), so the requirements have to fit the factory, not the other way around.
A related deadline already in motion
The ISV-H program isn't the only place these two pressures, speed and sourcing restrictions, are colliding for the same automakers. The Connected Vehicle Rule, finalized in January 2025 and kept in place under the current administration, bans Chinese-developed software from internet-connected vehicles starting with the 2027 model year, and Chinese-made hardware starting with the 2030 model year.
Because that rule reached its first deadline two years before the defense sourcing rule does, it offers an early look at how automakers are managing the transition.
Ford has applied to the U.S. Commerce Department for authorization to keep importing its China-built Lincoln Nautilus, because although its software is written in the U.S., it's installed onto the vehicle in China. GM has announced it will move Buick Envision production out of China to a Kansas plant, and has directed thousands of its suppliers to remove Chinese content from their own operations, with some deadlines set for 2027. Researchers at Rhodium Group have found that the hardware restrictions, which take effect in 2030, are likely to be more difficult and time-consuming for automakers to comply with than the software restrictions were.
For Ford and GM, the ISV-H contract may turn out to be less about whether they can build the truck, and more about whether the rules they now have to follow let them build it on schedule.
