Lockheed Martin confirmed Thursday that GM Defense delivered the first batch of mission-critical housing parts for its PAC-3 MSE interceptor missile on August 28, just 22 days after the two companies signed a formal contract.
That kind of speed is rare in defense manufacturing. Components like these typically take months, sometimes years, to produce through traditional supply chains.
GM (GM) stock climbed around 3% in early trading Thursday on the news. Lockheed Martin (LMT) was up roughly 0.80%.
GM Defense used casting and machining capabilities to manufacture the parts to defense specifications. The delivery represents the first batch under the new partnership between the two manufacturers.
Lockheed Martin did not disclose the value of the contract, the size of the order, or where the components are being produced.
Tim Cahill, president of Lockheed Martin Missiles and Fire Control, said the quick turnaround reflects the company’s focus on execution and delivery capacity.
Stephen duMont, President and CEO of GM Defense, said the partnership brings GM’s precision-fabrication expertise and manufacturing scale into defense production.
Lockheed Expanding Munitions Capacity
Lockheed Martin said it is investing $8-9 billion to grow its munitions production footprint. The company plans to increase production and warehousing space by around 50% across more than 20 sites in the United States.
The PAC-3 MSE program sits within Lockheed’s broader munitions portfolio, which also includes THAAD and PrSM systems. Both companies said they plan to apply the same commercial manufacturing approach to additional programs going forward.
The move comes as Lockheed faces pressure from the Trump administration to ramp up munitions output.
GM Looks to Defense for New Revenue
For GM, the defense push is part of a deliberate strategy to find new income streams in a difficult global auto market.
CEO Mary Barra highlighted the defense business on GM’s Q2 earnings call. She said GM anticipates $700M in defense revenue this year and is building a backlog of future business expected to deliver double-digit profit margins over the next several years.
The Lockheed partnership is a direct expression of that strategy. GM Defense is positioning itself as a precision manufacturer capable of meeting strict defense production requirements.
Both companies indicated plans to expand the collaboration beyond the PAC-3 program to cover future defense systems.
GM Defense’s delivery of the initial components on August 28, 2026, marks the first tangible output of the partnership since the contract was signed three weeks prior.
