President 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. The move comes as the U.S. military faces significant depletion of weapon stockpiles following sustained operations in the Iran war.
In his June 11 memorandum to Defense Secretary Pete Hegseth, Trump stated: “I hereby find that conditions exist which may pose a direct threat to the national defense or its preparedness programs.” He cited “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. Under the act, the Pentagon chief was delegated the power to consult with industry representatives to establish these voluntary partnerships, Reuters reported.
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.
Stockpiles Depleted by Iran War
The invocation reflects growing concern in Washington about the capacity of U.S. weapons manufacturers to meet demand. The Iran war has significantly depleted portions of the U.S. military’s munitions stockpiles. According to a May 27 analysis from the Center for Strategic and International Studies (CSIS) cited by Military Times, replenishing stockpiles of critical weapons systems could take until 2030 or 2031, creating what analysts described as a “window of vulnerability.”
The New York Times reported in April that the Iran war had significantly drained much of the U.S. military’s global supply of munitions, forcing the Pentagon to rush procurement of replacement weapons. 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. 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 should one arise in the next few years.
The Defense Production Act has been a tool used by recent administrations to accelerate domestic production of critical goods. Both Trump and President Biden previously invoked the act to boost critical mineral supplies, according to the Council on Foreign Relations. Biden used the act in March 2022 to designate lithium, cobalt, graphite, nickel, and manganese as essential to national security. Trump invoked the act during his first term in 2017 and twice in 2020, according to the International Energy Agency.
