General Motors is in discussions with Lockheed Martin to manufacture commonly used components that would help the defence contractor bolster munitions output, the Wall Street Journal reported on 15 June, marking the latest step in a wave of Western automakers entering or deepening their involvements with the defence sector. The companies are still negotiating which specific parts GM would produce; no agreement has been finalised and the terms remain subject to change. 

Sources also told WSJ that Chief Executive Mary Barra has held separate discussions with Trump administration officials about expanding GM’s role in defence, and the company’s shares rose 3.15% on the day of the report. Whatever fruit the discussions bear will serve to extend the automaker’s existing defence footprint, manifested in the GM Defense subsidiary, rather than creating one from scratch. The subsidiary has been operating for nearly a decade, producing infantry squad vehicles derived from the Chevrolet Colorado platform; a US$143m DoD contract awarded on 11 June for further squad vehicles and winch kits brought its cumulative defence contract value to more than US$620m.

The proposed Lockheed arrangement would move GM beyond vehicle platforms and into munitions-adjacent components, a meaningful escalation in the nature of its defence involvement. However, GM is not alone among the Detroit Three in pursuing opportunities in defence: Ford is also in active discussions with the US government and several European defence ministries about militarised versions of its F-Series Super Duty trucks, with Army Secretary Dan Driscoll explicitly citing Ford’s manufacturing scale as critical to addressing stockpile depletion accelerated by the Iran war. 

Things have arguably progressed at a faster speed in Europe, with many of the developments occurring in the last few days. Daimler Truck launched a unified Daimler Truck Defence brand on 15 June with a target of €1bn (US$1.16bn) in defence revenue by 2028, backed by a mid-three-digit million-euro investment. The same day, Scania unveiled a modular protected cab at Eurosatory 2026 in Paris, and Renault also revealed its 4 Troop militarised prototype with Thales.

GM already has contracts to produce infantry squad vehicles for the US Department of Defense

Elsewhere in Europe, Mercedes-Benz signed an memorandum of understanding with AI startup Tytan Technologies to supply vehicles for counter-drone systems on 10 June. Volkswagen also remains in discussions with Rafael Advanced Defence Systems over Iron Dome components at its Osnabrück plant. This was first reported by the Financial Times in April 2026.

The wave of developments appear to be the result of two simultaneous crises on opposing ends of the supply-demand equation. Traditional Western defence players—among them Lockheed Martin, Boeing, and KNDS—are operating near capacity and cannot surge output to meet the demand created by ongoing conflicts in Ukraine and Iran, as well as the NATO-wide rearmament that has followed on their feels

Automakers, by contrast, have idle factories, trained industrial workforces and supply chains engineered for high-volume production of more or less the kind of common-use components—precision-machined metal parts, electronics, logistics vehicles—that the defence industrial base currently cannot produce fast enough. Many are eyeing, or actively in the process of conducting, factory closures and mass layoffs due to weakened regional vehicle markets, particularly in Europe and China, as well as surging competition from Chinese automakers.

With every NATO member having met the 2% GDP defence expenditure target for the first time in 2025 and Germany alone committed to more than €500bn in defence investment this decade, the budget exists; the bottleneck is manufacturing capacity. Pressure from the US Trump administration has left European governments with larger defence budgets than they necessarily know how to spend, leaving large amounts of money on the table for the continent’s automakers to vie over.

It cannot be ignored that most Western automakers spent the 2010s actively distancing themselves from defence exposure under ESG pressure, only to find themselves operating below capacity in 2026 and in need of the kind of long-duration, government-backed revenue that defence contracts provide. The reversal is not a conspiracy: it is a rational response to a changed environment, but it has happened with a speed that has outpaced the ethical frameworks most of these companies put in place to govern exactly this kind of decision.

The limits of the pivot can no more easily be avoided: high-end munitions production requires specialist tolerances, security clearances, export control compliance and procurement culture that differ substantially from commercial vehicle manufacturing. The WSJ noted explicitly in its reporting that that there is limited overlap between automotive supply chain capabilities and the weapons components in shortest supply. Conversion timelines of 12 to 18 months for adjacent products and more than three years for more complex divergences mean the near-term capacity relief the Pentagon is seeking will not arrive quickly. 

Despite such limitations, the GM-Lockheed talks represent yet another turning point in a decade that has proven tumultuous for automotive. When the US’ best-selling automaker begins producing parts for the world’s largest defence contractor, the line between civilian and military industrial capacity has effectively dissolved. This time it will not happen as a wartime emergency measure, as in 1941, but as a survival response to a geopolitical environment that most of the industry had convinced itself would not return.
