The Pentagon has ordered the U.S. defense industry to dramatically accelerate weapons production, giving major contractors just 21 days to submit plans for faster deliveries after the war with Iran left American munitions stockpiles at their lowest levels in years. The directive, laid out in a memo from Deputy Defense Secretary Steve Feinberg and obtained by The Washington Post, marks one of the most urgent calls yet for industry to move at what officials are describing as wartime speed.
A 21-Day Ultimatum
Feinberg delivered the demand to defense industry leaders on Wednesday, telling them they had a maximum of three weeks to present plans to “drive significantly faster, more aggressive delivery schedules and/or increased production for critical capabilities.” The memo left little room for the kind of timelines the industry has historically relied on. “Years-long development cycles are not acceptable,” Feinberg wrote, adding that firms must “dramatically accelerate” their program schedules and “expand our production capacity now.”
Pentagon spokesman Sean Parnell confirmed the memo was authentic, saying it “will inform the fiscal year 2028 budget submitted to Congress for funding” and framing the push as part of a broader effort to rebuild the U.S. defense industrial base.
Air Defense Stockpiles Under Strain
The most acute concern inside the Pentagon centers on air-defense interceptors. The Center for Strategic and International Studies estimated that the global inventory of Patriot missiles fell from roughly 2,200 before the war with Iran to fewer than 827 afterward, while stocks of Terminal High Altitude Area Defense, or THAAD, interceptors dropped from 452 to under 278. Those figures reflect just how heavily the interceptors were drawn down defending against Iranian missile and drone attacks over recent months.
Separate reporting has painted an even starker picture of depletion. CNN reported that the U.S. military had used up close to 80 percent of its THAAD interceptors and roughly half of its Patriot interceptor stock, a level some officials described as dangerously low. Pentagon documents tied to a $67 billion emergency funding request reportedly included $18.2 billion earmarked to replace Patriot interceptors, Navy Tomahawks, and THAAD missiles.
Tom Karako, director of the Missile Defense Project at the Center for Strategic and International Studies, said the gap between announced intentions and binding commitments remains the core problem facing the Pentagon’s rebuilding effort. “Almost nothing has been contracted, and that’s the problem,” Karako said.
Industry Deals Already in Motion
The 21-day directive did not emerge in isolation. It follows a series of framework agreements the Pentagon has struck with major contractors in recent months aimed at expanding production capacity, even though those agreements remain nonbinding until Congress appropriates the funding behind them.
The most significant of those deals came on July 23, when the U.S. Army awarded Lockheed Martin a contract worth up to $58.6 billion to build Patriot interceptor missiles — the largest agreement of its kind, converting a previous one-year, $4.7 billion contract from April into a seven-year procurement framework covering fiscal years 2026 through 2032. The deal is intended to triple production of the PAC-3 Missile Segment Enhancement interceptor by the end of 2030 and formalizes a multiyear buy that could support roughly 2,000 missiles a year.
Lockheed, based in Bethesda, Maryland, has said the funding will let it expand its workforce at the Camden, Arkansas, plant by 50 percent, growing from about 1,200 to roughly 1,850 jobs, while investing an estimated $8 billion to $9 billion by 2030 to modernize more than 20 facilities, including new ammunition plants.
A parallel framework agreement was reached with RTX, the parent company of Raytheon, to expand production of Tomahawk cruise missiles. That deal is aimed at increasing Tomahawk output from the current rate of about 60 units a year for the U.S. to eventually 1,000 units annually.
The push to expand manufacturing has been paired with pressure from the Trump administration on contractors more broadly; in January, Trump signed an executive order directing officials to identify defense contractors considered to be underperforming on government contracts while pushing companies to prioritize meeting production demands over other business considerations.
Tension Inside the Pentagon
The scramble to rebuild stockpiles has coincided with reports of friction at the top levels of the administration over how the shortages were handled. The Washington Post reported that Trump clashed with Defense Secretary Pete Hegseth at Camp David, accusing him of misleading the White House about the true state of munitions stockpiles amid the possibility of renewed major combat operations against Iran. According to the report, Trump told Hegseth he believed the shortage of long-range and interceptor missiles “had been fixed,” and when pressed on the matter, Hegseth reportedly directed blame toward his deputy, Feinberg.
The shortage of interceptors was reportedly among the central concerns discussed between Trump and his top advisers before the administration decided to hold off on escalating its campaign against Iran toward the end of last month.
White House Press Secretary Karoline Leavitt disputed the account of the Camp David confrontation, saying it “literally never happened.” Trump himself addressed the reports directly on Thursday, defending Hegseth and dismissing the coverage. “Pete is highly respected within the Military, and has made tremendous improvements, including getting rid of DEI, and increasing recruitment to historic levels,” Trump wrote on Truth Social. He went further, calling the reporting on the shortages “treasonous” and warning that “the ‘leakers’ of these treasonous statements are being hunted down,” adding that “long term jail sentences will be sought.”
Trump also insisted the underlying premise of the reporting was false, writing that the United States has “massive amounts of ‘munitions’ especially of certain types,” and that “additionally, large amounts are being manufactured and shipped to the U.S.”
Congress Holds the Purse Strings
Despite the flurry of framework agreements and the new 21-day mandate, defense industry executives have repeatedly cautioned that expanded production ultimately hinges on funding that has not yet materialized. Industry leaders have welcomed the Pentagon’s push but noted that Congress must first appropriate money before companies can commit more heavily to new components, expanded supply chains, and additional production capacity. Exact terms and delivery dates for many of the Pentagon’s munitions agreements remain under negotiation.
That funding is tied up in a $1.15 trillion defense spending bill that has been stalled in Congress, a delay that threatens to slow the very production surge the Pentagon says it urgently needs. Without that appropriation moving forward, the nonbinding agreements struck with Lockheed, RTX, and other contractors risk remaining aspirational rather than contractual.
For now, the Pentagon is betting that public pressure and a hard deadline will push contractors to move faster even as the money question remains unresolved. Whether the 21-day ultimatum yields binding commitments — or simply more proposals awaiting congressional funding — is likely to become clearer once the fiscal year 2028 budget process Parnell referenced begins to take shape.
