APRIL 1, 2026 – The Department of War, in partnership with Boeing and Lockheed Martin, today announced a landmark framework agreement to triple the production capacity of seekers for the Patriot Advanced Capability-3 (PAC-3®) Missile Segment Enhancement (MSE).
This agreement marks a pivotal step in executing President Trump and Secretary Hegseth’s vision to build the Arsenal of Freedom, accelerate the delivery of critical capabilities to the warfighter, and create thousands of jobs across the defense industrial base.
This seven-year agreement with Boeing, a crucial supplier for the PAC-3 missile, directly supports the recently announced agreement with prime contractor Lockheed Martin to more than triple the output of the PAC-3 MSE all-up round.
It is a direct application of the Department’s new Acquisition Transformation Strategy, which prioritizes engaging directly with key suppliers at all levels of the industrial base.
This approach ensures the entire supply chain — not just the primes — have the stability and long-term demand signals necessary to invest in new facilities, tooling, and workforce development.
The seeker, produced by Boeing, provides active measurement data used for PAC-3 MSE missile guidance to ensure precision intercepts.
By securing this long-term commitment for seeker production, the Department is mitigating chokepoints and ensuring the industrial base can scale to meet the operational demands of the warfighter.
“To build a true Arsenal of Freedom, we must strengthen every link in the chain,” said Michael Duffey, Under Secretary of War for Acquisition and Sustainment. “This agreement with Boeing is a direct reflection that speed, volume, and a resilient supply chain are paramount. We are moving beyond the old model and forging direct partnerships with critical suppliers to ensure the entire defense industrial base is postured to expand production and deliver the decisive capabilities our warfighters need at speed and scale.”
This initiative is a core component of the Department’s broader effort to place the acquisition system on a “wartime footing,” prioritizing speed and flexibility to outpace adversaries.
By providing clear, stable, and long-term demand signals and fostering collaboration across the industrial base, the Department of War is ensuring that both the final products and the intricate supply networks that build them are robust, responsive, and ready.
