Pentagon gives industry 21 days to submit plans for ‘significantly faster’ weapons production

Recent combat with Iran has put pressure on U.S. munitions stockpiles as the Pentagon pushes defense companies to accelerate production and delivery of critical weapons.

Deputy Defense Secretary Steve Feinberg told defense-industry leaders in an Aug. 5 memo that they have 21 days to submit plans for “significantly faster, more aggressive delivery schedules and/or increased production for critical capabilities.”

“Years-long development cycles are not acceptable,” Feinberg wrote. “We must dramatically accelerate our program schedules and expand our production capacity now.”

The memo also asks companies to propose specific capital investments and facility expansions and to explain how they would work with the Pentagon to increase weapons production. Feinberg also called on industry to demonstrate its willingness to “put skin in the game.” Pentagon spokesman Sean Parnell said the responses will help inform the department’s fiscal 2028 budget request.

The increased demand comes as the U.S. has used large quantities of advanced munitions during the conflict with Iran, with recent estimates showing declines in stocks of key missile interceptors.

A Center for Strategic and International Studies analysis estimated that U.S. stocks of Patriot interceptors fell from 2,330 before the war with Iran, to between 759 and 827 after the latest round of operations. THAAD interceptor stocks fell from 452 to between 234 and 278.

The Pentagon’s challenge is not identifying how many interceptors have been used, but how quickly they can be replaced. CSIS estimates the delivery timeline for Patriot PAC-3 MSE interceptors at about 42 months and about 53 months for THAAD.

The urgent 21-day deadline was communicated to arms manufacturers like Boeing, Lockheed Martin and RTX.

RTX said in July that it had received its first U.S. domestic production order for GEM-T Patriot interceptors in more than 30 years, in a roughly $442 million Army contract. The order comes as the Pentagon not only seeks to increase production of newer Patriot and THAAD interceptors but also to expand its capacity for the components required to build them.

On July 27, the department announced seven-year framework agreements with industry to expand production of key propulsion components for PAC-3 MSE and THAAD interceptors. L3Harris said its PAC-3 agreement will nearly triple production of a range of propulsion products supporting the interceptor, while its THAAD agreement is intended to quadruple production of key propulsion components.

Feinberg’s memo asks companies to identify the areas where they can increase and accelerate production and delivery, and what would be required from the Pentagon in order to make that happen. The department will use the responses to determine what industry can deliver faster and what additional resources may be needed.

The memo’s scope extends beyond weapons used in the Iran conflict. Feinberg identified 16 critical programs under consideration for accelerated production or increased procurement in the fiscal 2028 review, including the Next Generation Interceptor, the National Advanced Surface-to-Air Missile System (NASAMS), a mobile air defense radar system and a space-based missile-tracking system.
