Deputy Defense Secretary Steve Feinberg gave U.S. defense contractors just 21 days to submit plans for faster weapons production after five months of conflict with Iran drained advanced missile interceptor inventories to levels that analysts warn could leave American forces exposed.
Feinberg sent the memo to industry leaders on Wednesday, directing them to outline how they would "drive significantly faster, more aggressive delivery schedules and/or increased production for critical capabilities," a copy obtained by The Washington Post showed. The 21-day clock leaves little room for the kind of drawn-out negotiations that typically define Pentagon procurement.
Pentagon spokesman Sean Parnell confirmed the memo Saturday, saying the department was focused on delivering "the weapons our warfighters need at the pace the threat demands." He called the directive "real" and said it would shape the fiscal year 2028 budget the administration sends to Congress.
The urgency is not abstract. The Center for Strategic and International Studies, a Washington think tank, estimated last month that Patriot missile interceptor stockpiles have fallen from roughly 2,330 before the conflict to somewhere between 759 and 827, a decline of at least 65 percent. THAAD interceptors, the military's high-altitude missile defense system designed to shoot down ballistic missiles outside the atmosphere, dropped from 452 to an estimated 234 to 278 after partial replenishment, a reduction of at least 38 percent.
The CSIS numbers tell a two-phase story. When the April ceasefire took effect, Patriot stocks had already fallen to 1,030, less than half the pre-conflict total. THAAD interceptors stood between 232 and 262.
But fighting resumed. Patriot inventories dropped another 200 to 270 interceptors. THAAD stocks saw only marginal replenishment, climbing to 234, 278 despite fresh production. The net effect: five months into the conflict, the United States holds roughly a third of the Patriot interceptors it started with and barely half its original THAAD supply.
Those interceptors protect American troops and allied air defenses across the Middle East. The CSIS analysis warned that diminished inventories raise the risk to U.S. forces if hostilities escalate again, a scenario no one in Washington can rule out.
Feinberg, the deputy defense secretary, did not couch his language in the usual bureaucratic hedging. From the memo:
"Years-long development cycles are not acceptable. We must dramatically accelerate our program schedules and expand our production capacity now."
The directive frames the production push as part of a broader effort to rebuild the defense industrial base, one Parnell said predated the five-month-old conflict with Iran. Whether that timeline holds up to scrutiny is an open question. The memo's tone suggests a department that recognizes the current pace of manufacturing cannot keep up with the rate at which weapons are being consumed.
No specific defense companies were named in the reporting on the memo. The 21-day deadline means responses are due within three weeks of Wednesday, a timeline that would force contractors to move faster than most Pentagon acquisition cycles typically allow.
The production push runs headlong into a political wall on Capitol Hill. The defense spending bill is currently stalled in Congress, where lawmakers have resisted the White House's request to increase Pentagon spending to $1.5 trillion, up from roughly $900 billion last year. Some members of Congress are described as fuming over the administration's military action against Iran, adding friction to an already difficult budget fight.
That gap between what the Pentagon says it needs and what Congress is willing to fund matters. Feinberg's memo will feed directly into the FY2028 budget request, but the money to pay for accelerated production has to come from somewhere. If Congress refuses to move, the Pentagon's 21-day deadline becomes an exercise in planning without funding.
President Trump addressed the stockpile concerns on Thursday in a Truth Social post, pushing back on public reports of a munitions shortage. He said the U.S. has "massive amounts" of weapons and that "large amounts are being manufactured and shipped to the U.S. as needed."
Parnell's Saturday statement aligned with that posture, framing the Feinberg memo not as an alarm but as a continuation of existing modernization plans. He said the directive is "entirely consistent with our ongoing push to rebuild the defense industrial base."
Framing aside, the CSIS figures present a straightforward problem. Patriot and THAAD interceptors are among the most sophisticated, and expensive, munitions the U.S. military fields. They are not items that can be stamped out on a factory floor in weeks. Production lines for these systems involve specialized components, long lead times, and supply chains that stretch across multiple continents.
Before the conflict, the U.S. held 2,330 Patriot interceptors. It now holds fewer than 830 at the high end of CSIS estimates. That is not a drawdown. That is a consumption rate that outpaced every assumption baked into pre-conflict planning.
Several questions remain unanswered. Which weapons systems beyond Patriot and THAAD are running low? What is the current production rate, and what rate does the Pentagon want to reach? Which allies in the Middle East depend on these interceptors for their own defense? The reporting does not say, and the memo's full contents have not been made public.
What is clear is that the Pentagon has moved from quiet concern to a written demand with a hard deadline, a shift that tells its own story about the state of American readiness.
Wars burn through munitions faster than peacetime bureaucracies can replace them. Washington has known that for decades. The question now is whether Congress, the defense industry, and the Pentagon itself can close the gap before the next round of fighting answers it for them.
