**Title: US Defense Secretary Hegseth Estimates Iran War Costs at $37.5 Billion**
**Date: July 21, 2026**
In a recent Senate Committee on Appropriations hearing, U.S. Secretary of Defense Pete Hegseth provided an updated estimate of the financial costs associated with the ongoing U.S.-Israel war against Iran, placing the figure at $37.5 billion. This figure marks an increase from previous estimates, including a $29 billion projection from the Trump administration in May.
During the hearing, Hegseth, alongside Chairman of the Joint Chiefs of Staff Dan Caine, faced inquiries regarding a substantial $1.5 trillion defense budget request, which encompasses nearly $70 billion allocated specifically for the conflict with Iran. The Secretary confirmed that the $37.5 billion estimate includes operational and maintenance costs projected through the end of September, although he did not disclose detailed breakdowns of these expenses.
The figure presented by Hegseth is notably lower than other assessments. For instance, Moody’s Analytics has estimated that the broader domestic impact of the war, including factors such as rising energy prices, could reach as high as $150 billion. This discrepancy highlights the complexity of calculating the true costs of military engagements, which often extend beyond direct expenditures.
The hearing took place amid escalating tensions and ongoing military operations. Hegseth's testimony followed the collapse of a memorandum of understanding that had briefly halted hostilities since June 17. As military actions resumed, former President Trump indicated that Iran would "pay" for the recent deaths of U.S. soldiers, further escalating the rhetoric surrounding the conflict.
In the wake of renewed hostilities, Trump has threatened to target critical infrastructure in Iran, including energy plants and nuclear facilities. The U.S. military has focused its strikes on locations that Iran utilizes to project influence over the strategically vital Strait of Hormuz. In retaliation, Iran has vowed to continue targeting U.S. assets in the region, with recent attacks reported in Kuwait, Bahrain, and Jordan, including assaults on desalination and power plants.
During the hearing, Hegseth also addressed concerns regarding the strain on U.S. military resources due to the ongoing conflict. He emphasized the need for increased funding to expand production capabilities for high-demand munitions, including solid rocket motors, Joint Direct Attack Munitions (JDAMs), and counter-drone technologies. Hegseth warned that without adequate budgetary support, future military training programs could be curtailed, highlighting the urgency of the current budget cycle.
Senator Patty Murray raised concerns about the extensive budget request, which also encompasses funding for various military operations, including National Guard deployments in Washington, D.C., and efforts against drug trafficking in the Caribbean. Murray expressed skepticism about the coherence of the budget proposal, questioning its overall rationale.
As the conflict continues, the implications of the war extend beyond military engagements, affecting both domestic economic conditions and international relations. The ongoing situation remains fluid, with military and political developments likely to influence future budgetary considerations and strategic decisions by U.S. leadership.
The Senate hearing underscores the complexities and challenges of managing military expenditures in a protracted conflict, as lawmakers grapple with the financial implications of U.S. involvement in the region.
