The U.S. Department of War signed seven-year framework agreements with General Dynamics and Lockheed Martin on August 31, 2026, to triple Patriot PAC-3 MSE and quadruple THAAD interceptor production. The deals establish minimum annual procurement quantities to give manufacturers predictable demand for expanding capacity. The move follows CSIS estimates that the U.S. has used 65% of its Patriot and 38% of its THAAD interceptors in conflicts with Iran and Ukraine.

Key Facts

The U.S. Department of War signed seven-year framework agreements with General Dynamics Ordnance and Tactical Systems and Lockheed Martin on August 31, 2026.
The agreements aim to triple PAC-3 MSE production capacity and quadruple THAAD interceptor capacity.
The Center for Strategic and International Studies estimated in July that the U.S. has dispensed around 65% of its Patriot inventory and 38% of its THAAD interceptors.
General Dynamics will increase output of motor cases, seeker housings, midsections, and shroud deployment systems for the interceptors.
A Patriot launching station can carry up to 12 PAC-3 MSE interceptors.

Production Expansion

The framework agreements establish long-term procurement commitments for specialized interceptor components and accelerated delivery schedules. The Department of War said the arrangements will give industry minimum annual procurement quantities, providing manufacturers and lower-tier suppliers a more predictable demand signal. General Dynamics will support the expansion by increasing output of motor cases, seeker housings and midsections, and shroud deployment systems. These parts are essential to producing complete interceptors, and expanding their availability is critical because missile output can be limited by lower-tier component bottlenecks as much as by final assembly capacity.

Stockpile Depletion

The ongoing conflict with Iran has depleted around two-thirds of the United States' pre-war Patriot missile interceptor inventory, according to a July report from the Center for Strategic and International Studies. The think tank estimated that the U.S. has dispensed around 65% of its Patriot inventory and 38% of its THAAD interceptors. The U.S. is draining those supplies on two fronts, both in Iran and by transferring large stockpiles of Patriot air defense interceptors and Army Tactical Missile Systems to Ukraine. That diminished inventory also reduces the U.S.'s ability to wage war and defend against other peer adversaries, notably China in the western Pacific, CSIS experts noted.

Interceptor Capabilities

The Lockheed Martin PAC-3 MSE interceptor uses hit-to-kill technology to destroy incoming threats through direct impact and is designed to engage tactical ballistic missiles, cruise missiles, aircraft and other advanced airborne threats. Its two-pulse solid-propellant rocket motor, enlarged control surfaces, and upgraded actuators increase maneuverability and engagement performance against fast, maneuvering targets during the terminal phase of an attack. The missile also provides substantial launcher density, with a Patriot launching station able to carry up to 12 PAC-3 MSE interceptors.
