WSJ: Pentagon approaches Detroit OEMs about weapons production

Senior US defence officials have held preliminary talks with the Chief Executives of General Motors, Ford Motor and other US manufacturers about whether their production capacity could be redirected toward weapons and military supplies, the Wall Street Journal reported on 15 April. The discussions, which also involved GE Aerospace and heavy vehicle maker Oshkosh, reportedly began before the war in Iran and are part of a broader effort by the Trump administration to expand the defence industrial base.

The Pentagon—now often referred to in official documents as the “Department of War”—has stated that its concern is capacity and speed. Officials asked automakers whether their companies could rapidly shift to defence work and identified barriers to doing so; matters ranging from contracting requirements to bidding processes. Oshkosh, whose core revenue is non-defence despite its existing military vehicle programmes, said it had been in dialogue with the Pentagon since November and has been proactively identifying capabilities that match military requirements. 

To be sure, there is some precedent for the inquiry: GM already operates a defence subsidiary producing a lightweight infantry squad vehicle based on the Chevrolet Colorado platform and is considered a leading contender to build the Army’s next-generation vehicle to replace the Humvee. Both GM and Ford were also crucial to the US’ ‘Arsenal of Democracy’ during the Second World War. 

Detroit’s automakers halted civilian production during the Second World War to manufacture bombers, aircraft engines, and trucks. It remains to be seen, however, how up to the task they will be for 21st Century warfare: modern weapons systems require specialist manufacturing tolerances and supply chains that differ substantially from vehicle production. All currently-available information indicates that the automakers themselves have not indicated any willingness to commit to the arrangement.

For the Pentagon, the rationale is straightforward. Years of weapons transfers to Ukraine and support for Israeli activities in the Gulf have whittled down US munitions stockpiles; the Iran conflict has only accelerated that depletion. In response, President Donald Trump requested a US$1.5tr military budget earlier in April—comfortably the largest in modern history—with major investments in munition and drone manufacturing among its stated priorities. Defence Secretary Pete Hegseth (now also the self-styled “Secretary of War”) has framed the industrial mobilisation as placing the US on a “wartime footing”, the language and intent of which clearly go beyond contingency planning.

The Pentagon’s outreach to Detroit reflects a wider pattern of civilian manufacturers—in particular automakers—being drawn into defence supply chains as geopolitical conditions deteriorate. Reporting from the Financial Times last month indicated that Volkswagen is in discussions with Israeli state-owned defence firm Rafael Advanced Defence Systems about converting its Osnabrück plant in Germany to produce components for the Iron Dome air defence system—transport trucks, missile launchers, and power generators, though not the missiles themselves. 

The German government is actively supporting the Rafael-Volkswagen proposal, which would preserve a site that currently faces closure in 2027. Germany has committed to more than €500bn in defence investment by the end of the decade, with air defence among its stated priorities. It remains to be seen, however, whether the works’ council will lend their support. Osnabrück has been singled out as one of the plants most exposed to potential closure amid Volkswagen’s ongoing restructuring campaign.

For Western automakers already navigating tariffs, an electric vehicle transition, software mastery and diminished consumer demand, the defence conversation adds a further dimension of strategic uncertainty. And, potentially, it could offer an alternative revenue stream at a moment when a majority of them need one.
