Senior officials at the Pentagon affirm they possess an ample reserve of ammunition to carry on the hostilities in Iran, even though reports indicated that its inventory of essential weaponry and interceptors was exhausted during the initial four days of the confrontation.
Defense Secretary Pete Hegseth and Chairman of the Joint Chiefs of Staff Dan Caine announced in a March 4 press briefing for reporters that the United States is transitioning from the precision-guided standoff ordnance employed in the early stages to substitute armaments, like the Joint Direct Attack Munition, which are considerably more economical now that a large portion of Iran’s aerial defense systems have been obliterated.
Hegseth mentioned that the Department of Defense holds “a nearly limitless supply” of substitute weapons from which it can draw.
“Initially, we utilized more sophisticated standoff munitions, but they are no longer necessary,” Hegseth stated. “Our caches of those, as well as Patriot [interceptors], remain exceptionally robust. The adversary is no longer able to launch the volume of missiles they once could, not even close.”
Caine, who noted that U.S. forces have struck over 2,000 targets since Feb. 28, maintained that the department possesses enough precise munitions “for the current mission,” adding that the Pentagon regards further specifics about weapon availability as “an operational security concern.”
“This marks a shift in munitions,” he commented. “The intensity is increasing, as the secretary articulated, rather than diminishing. This will enable us to maintain consistent pressure on the adversary in the coming period, disrupt their launch schedules, and impose costs continuously, day and night.”
Concurrently, President Donald Trump posted on Truth Social on March 3 that the U.S. military’s stock of “medium- and upper-medium-grade” munitions had “never been higher,” adding that the department has “a virtually boundless quantity of these armaments.” He conceded, however, that its inventory of higher-end weapons is “not where we desire it to be.”
When questioned multiple times during a March 4 House Armed Services Committee hearing to address the president’s assertions, Under Secretary of Defense for Acquisition and Sustainment Michael Duffey deferred to Caine’s previous declaration.
“I have immense trust in the professional military judgment of Gen. Caine, and he affirmed this morning, unequivocally, that we possess adequate munitions to support current and future operations,” he declared.
Even as Pentagon officials endeavored to alleviate concerns about weapon shortages, the White House was reportedly preparing a supplemental financial package to fund operations in Iran. Reuters was the first to report that several defense contractors were scheduled to meet with administration officials on March 4 to discuss munitions manufacturing.
Undersecretary of Defense for Policy Elbridge Colby, speaking at the Council on Foreign Relations, acknowledged the potential requirement for additional funding.
“Regarding the expenses, my understanding is that further requests may be forthcoming,” he remarked.
The department has finalized several multi-year agreements with munitions suppliers in recent months, aiming to boost the production of crucial weapons, but Duffey clarified that these endeavors are focused on increasing long-term supply, rather than catering to current operations.
In January, the Pentagon disclosed a seven-year framework agreement with Lockheed Martin to accelerate the fabrication of Patriot PAC-3 interceptors, more than tripling output from 600 units in 2025 to 2,000 annually by the conclusion of the decade. A subsequent agreement with Lockheed seeks to quadruple the production of Terminal High Altitude Area Defense interceptors, from 96 to 400 per year.
In February, RTX entered into a contract with the department to augment the production of five munitions: AMRAAMs, Tomahawks, and three variations of its Standard Missile series.
“We are employing multi-year procurement authority to provide a stable, clear demand signal to the industry, to afford them the confidence and stability to invest their own capital, leading to reduced costs for taxpayers and a more robust and productive defense industrial base,” Duffey explained.
To facilitate expanded munitions production, Duffey announced in January that the department would inject $1 billion into L3Harris’ solid rocket motor division, acquiring a minority stake in the enterprise. Lawmakers, some of whom were skeptical of the Pentagon’s move to purchase equity in defense companies, requested more elaborate information in the coming days concerning the metrics the department will utilize to ensure companies channel their own internal funds into areas prioritized by the department.
Duffey affirmed that the Pentagon has mechanisms in place to oversee whether companies are upholding their part of the arrangement.
“Part of the understanding was that, as we make an investment, they make a reciprocal investment—multiples of ours—and then we have established benchmarks for when those investments will materialize, so that we can guarantee that the investment stimulates the necessary growth,” he elaborated. “We perceive this as an economic interest in the company. We are not pursuing control.”
Rep. Adam Smith, D-Washington, however, conveyed apprehension that such equity deals could potentially harm competition among weapon manufacturers.
“Evidently, more capital can be beneficial,” he stated. “But we also wish to avoid discouraging fair competition that motivates individuals to enter this sector. If they believe the government will intervene and unfairly influence the situation, it could deter some of the investment we have witnessed.”
