Automotive manufacturing techniques expedite missile production in US defence strategy

The United States is increasingly borrowing ideas from the auto industry to help solve one of modern air defence’s hardest problems: how to make enough interceptor missiles fast enough.

According to Lockheed Martin, GM Defense delivered the first mission-critical PAC-3 Missile Segment Enhancement components in less than a month after the companies signed a formal contract, with the turnaround taking just 22 days. The defence contractor said the work shows how commercial manuf...

acturing techniques can be used to accelerate weapons production and reinforce the wider industrial base.

The PAC-3 MSE is the most advanced interceptor in the Patriot air and missile defence system, built to destroy ballistic missiles, cruise missiles, aircraft and other high-value aerial threats by direct impact. Its importance has grown as militaries confront more frequent missile and drone attacks, and as stockpile pressure has mounted in conflicts that consume interceptors at a pace that few traditional supply chains can easily match.

Lockheed Martin has already produced more than 2,500 PAC-3 MSE interceptors, but demand from the United States and its allies continues to rise. The company said earlier this year that it had delivered 620 missiles in 2025, after increasing output by more than 60% over the previous two years. In January, the US government and Lockheed Martin also agreed a seven-year expansion framework aimed at lifting annual production from roughly 600 missiles to 2,000 by the end of 2030.

The bottleneck is not only in final assembly. The missile depends on a dense network of specialist parts, including structural components, propulsion elements, guidance electronics, control systems and energetic materials. If even one supplier falls behind, the entire production line can slow. Lockheed Martin has said it plans to add automation, labour and tooling, while broadening its supplier base. GM Defense’s role is intended to relieve one part of that pressure by providing components that can be made using high-volume automotive manufacturing methods rather than conventional defence production timelines.

The scale of the build-up is being underwritten by the Pentagon. Lockheed Martin received a $4.7 billion contract action in April to accelerate PAC-3 MSE production, followed in July by a modification worth up to $53.86 billion over seven years. Together, the arrangements take the potential value of the multi-year programme to $58.62 billion and give industry a stronger signal to invest in new facilities, equipment and workers.

Lockheed Martin says the effort is aimed not just at the US military but at allies as well, with the PAC-3 MSE playing a central role in layered air and missile defence. At the same time, Washington is trying to preserve the expensive interceptor for the hardest targets. For cheaper threats such as drones, the US is developing lower-cost interceptors and electronic warfare options, while Lockheed Martin has also promoted the less costly PAC-3 ACE as a way to reserve PAC-3 MSE rounds for ballistic missiles and other higher-end dangers.

The broader lesson, defence industry analysts say, is that future missile production may depend as much on manufacturing speed and supply-chain flexibility as on missile design itself. In that sense, the GM Defense deal is more than a one-off contract: it is a test of whether the methods that build cars at scale can also help arm a military facing a faster, more demanding age of warfare.
