Iran war’s estimated US cost reaches $43.6 billion
WASHINGTON — The U.S. military estimated that operations connected to the Iran war cost $43.6 billion through Sept. 3, providing Congress with the latest accounting of the conflict’s direct military expenses.
U.S. Central Command, which oversees American operations across the Middle East, prepared the estimate. The United States and Israel launched the war against Iran on Feb. 28.
The new figure is $5.6 billion higher than the Congressional Budget Office’s estimate of $38 billion through Aug. 1. The nonpartisan budget office projected that the continuing conflict could add approximately $3 billion in expenses each month, depending on the intensity of military operations. (Associated Press)
Weapons account for more than half of the total
Munitions represent the largest category in the Central Command assessment, accounting for substantially more than half of the reported cost.
American weapons expenses increased from $21.7 billion in the earlier congressional estimate to $28.1 billion as of Sept. 3—a rise of $6.4 billion in slightly more than one month.
The most heavily demanded weapons include defensive missile interceptors fired from the Army’s Patriot and Terminal High Altitude Area Defense systems, commonly known as THAAD.
Those systems are designed to detect and intercept incoming missiles. Their use has increased as Iran and affiliated forces have fired missiles and drones at American military positions and regional partners.
The rapid expenditure of advanced interceptors has created concerns about the United States’ ability to replenish its inventory while meeting defense commitments in other regions.
Monthly costs expected to continue
The Congressional Budget Office said the war’s future expenses would depend on operational intensity.
Its earlier estimate placed the monthly cost at up to $3 billion, although significant changes in the pace of attacks, missile interceptions or American deployments could alter that figure.
The $43.6 billion assessment includes the cost of operating ships, aircraft and military bases. It also includes lost equipment and medical support for service members.
The total reflects direct military expenses and does not capture every financial consequence associated with the war. The conflict has contributed to higher oil prices, stock-market volatility and broader economic uncertainty. (Associated Press)
Damage to US bases is not included
The latest estimate does not include the cost of repairing damage to American bases across the Middle East.
Iran has targeted U.S. installations with ballistic missiles and drones during the conflict. A Pentagon inspector general’s report said Iranian attacks damaged or destroyed hundreds of buildings and other structures at bases in Bahrain, Iraq, Jordan, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates.
The watchdog also documented equipment losses and disruption to American supply operations. Central Command was forced to reroute some logistical activities to more distant locations after attacks damaged regional infrastructure.
Because those repair and replacement expenses were omitted, the conflict’s total eventual cost could be substantially higher than the current $43.6 billion estimate. (Associated Press)
War has killed 18 Americans and wounded more than 830
Pentagon figures list 18 American service members killed and more than 830 wounded during the conflict, according to the Defense Casualty Analysis System.
The reported financial total does not fully reflect long-term medical care, disability benefits and other costs associated with military casualties.
The war has also disrupted international energy markets and shipping routes, particularly around the Strait of Hormuz. Rising energy costs have affected consumers, businesses and financial markets beyond the conflict zone.
The war’s public approval and economic consequences have also become issues in the November midterm elections, when control of Congress will be decided.
Trump administration seeks major defense funding
The updated estimate emerged as the Trump administration requested a proposed $1.5 trillion military budget.
The White House is also asking Congress to approve a separate $95 billion package to help finance the Iran war and other national-security priorities.
Defense Secretary Pete Hegseth promoted the larger budget during a speech at Saronic Technologies, a company in Austin, Texas, that manufactures drones for the Navy.
“We’re asking for $1.5 trillion in the current budget to make generational investments to keep our country strong and sustain good, high-paying jobs for American manufacturers like Saronic,” Hegseth said. “We will deliver on this generational investment. We will fund this department.”
Congress must approve the administration’s spending proposals before the money can be allocated.
Democratic senators seek fuller accounting
Democratic senators sent Hegseth a letter requesting a comprehensive account of the Iran war’s costs.
The senators criticized the Defense Department for not releasing enough budget information to Congress and the public while military casualties and taxpayer expenses continue to increase.
The Central Command document provided to Congress was a one-page breakdown. It listed major expense categories but did not include the full costs of infrastructure damage or all potential long-term obligations.
The request for greater transparency follows the Congressional Budget Office’s statement that the Pentagon did not provide all the information it sought when preparing its independent estimate.
Missile shortages create concerns beyond the Iran war
The extensive use of Patriot and THAAD interceptors is affecting American stockpiles needed for other security commitments.
U.S. and NATO officials have described the shortage of some defensive missiles in Europe as “beyond critical.” The concern comes as European allies continue to assess their air-defense needs.
Saudi Arabia is also running low on interceptors as it confronts missile and drone attacks associated with Yemen’s Iran-backed Houthi rebels. Riyadh has sought assistance from regional and Western partners.
The shortages demonstrate how the Iran war’s costs extend beyond the dollar amount reported to Congress. Replacing sophisticated defensive missiles requires funding, manufacturing capacity and time, potentially affecting U.S. and allied readiness in several regions.
