A pivot into weapons production adds another layer of complexity to an already challenging business landscape, but for some OEMs it could serve as a lifeline. By Stewart Burnett
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 manufac
