Pentagon seeks $67bn emergency funding as Iran war cost estimate climbs to $37.5bn
Defense Secretary Pete Hegseth told the Senate Budget Committee on Tuesday that the conflict will cost $37.5 billion through September, a nearly 30% increase from the previous estimate, as nightly airstrikes resume after the ceasefire collapsed two weeks ago.
Hearing on Capitol Hill
Defense Secretary Pete Hegseth and Chairman of the Joint Chiefs of Staff Dan Caine testified before the Senate Budget Committee on Tuesday, July 21, to make the case for an emergency funding injection. Hegseth told senators that the Pentagon needs an additional $67 billion to cover "urgent needs" stemming from the war in Iran. The hearing came as the conflict entered a new phase of intensity following the collapse of a fragile ceasefire. Hegseth provided the committee with an updated cost estimate: the war will have cost $37.5 billion by the end of September, a figure that includes expenses such as troop meals and other operational costs. The Pentagon is running short of both money and time, according to Hegseth's testimony.
Cost escalation
The $37.5 billion projection marks a nearly 30% increase from the $29 billion estimate the Pentagon gave in mid-May. The sharp rise reflects the resumption of large-scale combat operations after the truce broke down. Hegseth did not offer a detailed breakdown of the spending, but the new total covers costs incurred since the start of the conflict and projected expenditures through the end of the fiscal year. The $67 billion supplemental request is intended to prevent a funding shortfall and sustain military operations beyond September. Lawmakers are expected to scrutinize the request in the coming weeks.

Ceasefire collapse and nightly airstrikes
The ceasefire between the United States and Iran collapsed approximately two weeks ago, around the first week of July. Since then, American forces have conducted nightly bombing raids on Iranian targets, according to Hegseth's testimony. The renewed air campaign has significantly increased the operational tempo and daily cost of the war. The Pentagon has not disclosed the specific targets or the number of sorties, but the nightly strikes suggest a sustained effort to degrade Iranian military capabilities. The breakdown of the truce has dashed hopes for a diplomatic resolution in the near term.

Funding request and congressional response
The $67 billion supplemental appropriation is separate from the regular defense budget and requires approval from both chambers of Congress. Hegseth and Caine faced questions from senators about the administration's strategy and the long-term costs of the conflict. While the hearing focused on the financial dimensions, it also highlighted the political challenges of sustaining a war that has now lasted over a year. The Trump administration argues that the funds are essential to protect US national security interests and to pressure Iran into a more permanent settlement. With the war's price tag rising and no end in sight, the request is likely to spark a contentious debate on Capitol Hill.
