General Motors Co. is in discussions with Lockheed Martin Corp. about manufacturing components for the defense contractor's weapons systems, the Wall Street Journal reported Monday, marking the second major automaker-defense partnership to emerge this week as the industry pivots toward military production.
"The contours of the arrangement could still change, and an agreement hasn't been finalized," the Journal reported, citing people familiar with the matter. GM would produce commonly used parts that could help Lockheed bolster munitions production, the report said, without specifying which components or a potential deal value.
The talks come as the U.S.-Iran war and weapons sent to Ukraine over the past three years have depleted American munitions stockpiles. The Trump administration last week planned to meet executives from the largest U.S. defense contractors at the White House to discuss accelerating production, Reuters reported June 10. The potential GM-Lockheed tie-up would give the defense prime access to automotive-scale manufacturing capacity — a model that mirrors the Renault-Thales military vehicle partnership announced Monday at the Eurosatory defense exhibition in Paris, where more than 2,600 exhibitors from 68 countries gathered.
The shift reflects a broader structural change in the defense industrial base. The European Union's ReArm Europe plan, adopted in March 2025, aims to mobilize roughly 800 billion euros in defense investment through 2029, combining fiscal flexibility for member states with a 150 billion euro EU-backed loan instrument called the Security Action for Europe. At Eurosatory, which opened Monday at the Paris-Nord Villepinte Exhibition Centre, Renault Group and Thales unveiled their own military vehicle collaboration, while General Motors' potential entry into defense supply chains signals that the boundary between civilian automotive manufacturing and military production is narrowing on both sides of the Atlantic.
For GM, the move would represent a strategic diversification beyond its core automotive business at a time when the company faces pressure from slowing EV adoption and rising raw material costs. The Detroit-based automaker's manufacturing footprint — spanning engine plants, transmission facilities, and assembly lines across North America — could be repurposed for defense production without the capital expenditure required to build new facilities from scratch. Lockheed, the world's largest defense contractor by revenue, has been seeking to expand its supplier base as the Pentagon pushes for faster munitions replenishment. The U.S. defense budget for fiscal 2026, still under negotiation, is expected to include significant increases for munitions procurement, according to congressional budget documents.
