Operation Epic Fury and the Munitions Debate
Since the start of Operation Epic Fury against Iran, the United States has fought for ten weeks, prompting a dispute over whether it still has sufficient munitions for current and future operations.
Data & Statistics
CSIS analysis shows that in the first 39 days the United States may have used over half of its pre-war inventory of four of seven key munitions, including THAAD, while short- and medium-range missile stocks stay sizable but long-range munitions are sharply reduced, prompting a three-year plan to triple production; the United States spends $1 trillion a year on defense, more than the next nine spenders combined.
Why It Matters
Analysts warn that depleted stocks create a “window of vulnerability” that could embolden China, North Korea, or other adversaries, and that reduced inventories also threaten the ability to supply allies such as Ukraine, weakening collective security.
Official Statements & Responses
Secretary of War Pete Hegseth told the House Appropriations Subcommittee on May 12 that the munitions issue had been overstated and that the department possessed all necessary munitions, while CSIS says the United States “does have enough missiles to continue fighting Operation Epic Fury ‘under any plausible scenario.’” Brookings’ Michael O’Hanlon cautioned that inventories, while low, have not fallen below “some mystical minimum,” emphasizing strategic uncertainties.
Criticism & Opposition
Army major general John Ferrari warned the United States is “running out of certain types of weapons for the type of war we like to fight.” Marine colonel Mark Cancian described the situation as “a near-term risk” and a “window of vulnerability.” Boise State professor Michael Allan called the reports “concerning and somewhat surprising.” Senator Mark Kelly said “shocking how deep we have gone into these magazines,” arguing that depletion endangers American safety worldwide.
Conflicting Reports & Gaps
Hegseth’s confidence contrasts with CSIS data showing >50 % depletion of four key munitions. The Pentagon’s classified inventory numbers remain undisclosed, preventing independent verification of risk thresholds.
Verbatim Quotes
- “The munitions issue has been foolishly and unhelpfully overstated,” — Pete Hegseth, Secretary of War
- “We're running out of certain types of weapons for the type of war we like to fight. We're running out of the expensive, exquisite ones,” — John Ferrari, Army Major General
- “It’s shocking how deep we have gone into these magazines," Kelly said, noting it would "take years" to replenish.” — Mark Kelly, U.S. Senator
- “inventories of several key weapons creates a window of opportunity "would be making a huge and quite probably foolish roll of the dice," he said.” — Michael O’Hanlon, Brookings Institution
What’s Next
The Department of Defense will triple munitions production, but officials acknowledge that restoring depleted stocks will take many years. Analysts warn that without accelerated replenishment, future contingencies—especially in the Indo-Pacific—could expose the United States to heightened strategic risk.
