The conflict with Iran has cost the United States $43.6 billion, according to U.S. Central Command (CENTCOM) data sent to lawmakers and shared with the media on Friday. The financial assessment, which tracks expenditures through September 3, reveals that nearly two-thirds of this total is expected to go toward replenishing depleted ammunition stockpiles.
Of the overall figure, the Pentagon has committed approximately $11.2 billion to active military operations and estimates that an additional $28.1 billion is required to replace spent munitions. Another $4.3 billion has been set aside to replace lost equipment. However, Bloomberg reports that this $43.6 billion total excludes the likely billions of dollars needed to reconstruct U.S. bases and other military infrastructure damaged or destroyed by Iranian strikes in the region.
According to a Pentagon inspector general report issued on Monday, Iranian assaults damaged or demolished hundreds of buildings and structures at U.S. military installations spanning eight nations in the Middle East. High-tech radar systems, which are highly expensive, were also damaged or ruined at multiple U.S. facilities. The inspector general's report noted that the conflict
"resulted in strategic inventory shortfalls and revealed industrial base bottlenecks for munitions resupply,"
An earlier analysis by the Center for Strategic and International Studies (CSIS) indicated that the majority of the ammunition spending was driven by efforts to shoot down Iranian missiles and drones. In June, the think tank estimated that roughly 58% of the projected spending was dedicated to air-defense interceptors, including Patriot and THAAD missiles, which has strained existing stockpiles. CSIS wrote in a May update that the U.S. may have used more than half of its prewar supply of Patriot, SM-3, and THAAD interceptors during the hostilities. Meanwhile, President Donald Trump has consistently rejected claims of ammunition shortages, labeling reports and leaks concerning depleted U.S. weapon reserves as "treasonous."
During a September 8 attack on a U.S. base in Jordan, American forces launched 60 to 70 Patriot interceptors and more than a dozen THAAD missiles to counter an Iranian barrage of approximately 20 ballistic missiles, the Wall Street Journal reported, citing unnamed officials. This single engagement consumed an amount of ammunition equivalent to what U.S. forces typically utilized over an entire week at other times in the conflict. According to the Wall Street Journal's sources, Iran has adjusted its strategies to intentionally deplete U.S. munitions, employing warheads that separate into multiple projectiles as they approach their targets. Reuters also reported that this particular strike caused damage to several U.S. military aircraft.
Why It Matters
The strain on U.S. air defense stockpiles highlights a broader vulnerability within the American defense industrial base, which has struggled to keep pace with the high consumption rates of modern, near-peer conflicts. Unlike conventional munitions, sophisticated interceptors like the Patriot and THAAD systems require highly specialized supply chains and can take years to manufacture. This bottleneck has raised concerns among defense planners about the military's readiness to handle simultaneous, prolonged conflicts in multiple theaters, such as the Middle East and the Indo-Pacific. Consequently, the high cost and rapid depletion of these assets underscore the growing strategic challenge of asymmetric warfare, where relatively low-cost drones and missiles can force adversaries to expend highly expensive defensive countermeasures.
