Pentagon Admits Strategic Ammunition Shortage After War with Iran: $22.3 Billion in Munitions Spent

The Pentagon has officially acknowledged that in the first months of the war with Iran, the United States expended such a volume of ammunition that it led to a strategic shortage of stockpiles and exposed vulnerabilities in the defense industrial base. These conclusions are contained in a report by the U.S. Department of Defense Inspector General, which covers the actions of the American armed forces as of June 30, 2026.

Acknowledgment of the Shortage by the Agencies

In an interview with the Department of Defense's independent oversight body, representatives of the procurement agency confirmed that the country faced a shortage of ammunition stockpiles. According to the report, the agency "is working on optimizing procurement processes and production timelines, as well as on building stockpiles of critical materials, components, and specific types of munitions for rapid response in the event of unforeseen circumstances." As Bloomberg notes, the document became official confirmation of a problem that the administration had previously systematically downplayed.

Scale of Expenditures and Losses

According to the figures cited in the Inspector General's report, by the end of June, $22.3 billion worth of ammunition had been expended in the course of the war, while total costs over the same period exceeded $33 billion. U.S. Central Command told the inspector that Iranian military forces damaged or destroyed "hundreds" of buildings and structures on American bases in the region, and U.S. diplomatic missions in four countries sustained damage as a result of strikes. As of the end of July, 11 American service members had been killed in action, and another seven died during the "Epic Fury" operation for reasons unrelated to combat; by the end of June, more than 400 service members had been wounded in action.

Contradictory Data

There is a notable gap between official statements and the oversight body's findings. White House chief Donald Trump repeatedly stated that the United States has "an enormous quantity of ammunition stockpiles," of which "far more than America could ever use in a war." In July, U.S. Ambassador to the United Nations Mike Waltz directly refuted reports of depleted military arsenals amid the conflict with Iran, asserting that the American military has all the resources necessary to conduct the campaign effectively. At the same time, the Inspector General's report records the opposite — a strategic shortage — and, according to the WSJ, as early as August the Pentagon had appealed to American industry to rapidly ramp up the production and supply of weapons, including munitions that are "acutely in short supply" due to the war with Iran. Thus, the public rhetoric of "endless" stockpiles is at odds with the agency's internal assessments and its requests to defense contractors.

Reaction and the State of the Industrial Base

The Pentagon's acknowledgment of the problem indicates that the intensity of combat use in the conflict with Iran exceeded the reserves built into the plans. The agency, by its own account, is revising its procurement logic and production timelines, as well as forming strategic reserves of critical materials and components. The August appeal to industry, recorded by the WSJ, indicates that replenishing stockpiles is being treated as a task requiring the mobilization of defense production capacity, rather than a mere adjustment of logistics.

Context and Possible Consequences

The published report becomes the first systematic document in which the Pentagon openly assesses the price of the war with Iran in financial and material terms. Combined losses of over $33 billion, significant destruction of infrastructure at bases and in diplomatic missions, and the confirmed ammunition shortage form the basis for a review of U.S. strategic reserves. For Washington, this means the need to simultaneously conduct combat operations and lay the groundwork for replenishing arsenals, which in effect acknowledges the limits of the speed at which the American defense industry can replace losses in the course of a prolonged conflict.
