Trump Invokes Defense Production Act To Expand Munitions Production And Supply Chains
Key Takeaways
- Trump invoked the Defense Production Act to boost munitions production amid Iran war stockpile depletion.
- Memo delegates Defense Secretary to use the Act to jumpstart key munitions production.
- Stockpiles depleted by ongoing Iran conflict drove urgency to replenish supply chains.
DPA invoked for munitions
U.S. President Donald Trump invoked the Defense Production Act of 1950 on June 11 to address constraints in munitions production and supply chains, according to a memo to Pentagon leadership made public on Tuesday.
“President Trump has invoked the Defense Production Act to address constraints in the production of munitions, according to a presidential memo released on Tuesday”
In the June 11 memorandum to Defense Secretary Pete Hegseth, Trump wrote, “I hereby find that conditions exist which may pose a direct threat to the national defense or its preparedness programs.”
The memo cites “limited production capacity, fragile supply chains, long-lead dependencies, and related production bottlenecks” as justification for the action, according to Reuters.
The Defense Production Act allows the president to grant authority to pursue voluntary agreements with private industry aimed at shoring up the defense industrial base when conditions pose a direct threat to national security, and Reuters reported that the Pentagon chief was delegated the power to consult with industry representatives to establish these voluntary partnerships.
Solid rocket motors, igniters, and guidance systems are among the most critical and capacity-constrained sub-systems needed for weapons production, both for legacy systems and future modernization programs, according to the memo details released by Reuters.
Hegseth denies shortage
NBC News said Trump quietly invoked the Defense Production Act last week to address rising concerns within his administration about the shortfall of munitions, and it described the move as forcing defense companies to quickly produce more weaponry.
NBC News reported that Trump met with Senate Republicans about a $350 billion reconciliation package for additional Defense Department funding to replenish stockpiles depleted during the U.S.-led war with Iran, and it quoted Sen. John Cornyn, R-Texas, saying the Pentagon is “running short of funding they need in order to acquire the weapons and missiles and things like that that they need to protect the nation.”

In contrast, Hegseth denied there is a munitions shortage, telling CBS’ “Face the Nation,” “Our stockpiles are strong and they will only get stronger in the future.”
CBS News reported that Michael Cadenazzi, the assistant secretary of defense for industrial base policy, said about the Defense Production Act at a Center for New American Security event on Tuesday, “Sometimes we need the collective wisdom of all the assembled companies to collaborate and solve our problems for us.”
CBS News also said the memo delegates the Defense Secretary to use the Defense Production Act and that the mechanism is warranted because fragile supply chains and production bottlenecks may “impair the ability” for the U.S. to expand the availability of munitions, missiles and equipment required for the national defense.
Stockpile timelines and stakes
The White House and Pentagon debate the scale of the problem as analysis cited by Military Times and CSIS suggests replenishing stockpiles of critical weapons systems could take until 2030 or 2031, creating what analysts described as a “window of vulnerability.”
“'Iran has never lost negotiations' — a confrontation between Trump and a journalist who reminded him of an old remark”
Al Jazeera reported on May 28 that restoring pre-war stockpiles of critical U.S. munitions would take at least two years, according to CSIS analysis, while CNN reported in April that the U.S. military had significantly depleted its stockpile of key missiles during the Iran war, creating a “near-term risk” of running out of ammunition in a future conflict.
CNN also reported that on Wednesday Trump said that the last two days of the war were “brutal” and that “$200 million worth of bombs” were used, tying the depletion concerns to the Iran campaign.
In the CBS News account, Defense Secretary Pete Hegseth told Margaret Brennan on “Face the Nation” that the U.S. is facing a “crisis” with its munitions stockpile, even as he previously testified in April it could take “months to years” to replenish what has been used against Iran.
The stakes are framed in the memo’s language that systemic constraints in the munitions industrial base may “impair the ability of the United States to produce, sustain, and expand the availability of munitions, missiles, and equipment required for the national defense,” and it directs Hegseth to “provide for the making of voluntary agreements and plans of action to help provide for the national defense.”
