2026年8月18日，美国海军尼米兹级航空母舰“乔治·华盛顿”号飞行甲板上的F/A-18“超级大黄蜂”战机准备起飞，该航母当时正前往印度洋支援美军在伊朗战争中的军事行动。
据两名知情人士透露，五角大楼于周五告知国会，美国对伊朗的战争已耗资451亿美元。
消息人士补充称，国防部向议员们通报，截至9月3日，战争开销为436亿美元，另有额外的15亿美元用于额外燃油开支。
不过，这一估算并未涵盖战争的全部成本。
一名消息人士称，该估算未包括受损基地或建筑的修复成本，也未如议员们所要求的那样，向国会提供军事行动间接成本的详细明细。
五角大楼给出的451亿美元成本估算，超过了美国国会预算办公室预计的截至8月1日的380亿美元战争开支，且在此之前，五角大楼曾在7月估算这场战争的花费为375亿美元。
美国国会预算办公室的估算同样未包含美军在战争中受损设施的修复成本，该办公室表示，大部分开支来自弹药支出。国会预算办公室预计，8月1日之后，这场战争每月仍将给美国造成约20亿至30亿美元的损失，在战斗升级期间，成本预计会更高。
该办公室还告知国会，这场战争预计将在2027年第一季度推高通胀，在美国民众对经济日益担忧之际，进一步推高各项成本。

The US war with Iran has cost $45.1 billion, the Pentagon informed Congress on Friday, according to two sources familiar with the matter.
The department told lawmakers that war costs were $43.6 billion as of September 3 plus an additional $1.5 billion for extra fuel, the sources added.
The estimate is not a full accounting of the war’s cost, however.
It does not include an assessment of the cost to repair damaged bases or buildings and did not provide Congress with detailed breakdowns of indirect costs of military operations as lawmakers have asked for, one source said.
The $45.1 billion cost estimate from the Pentagon surpasses the $38 billion price tag the Congressional Budget Office projected the war cost through August 1, and comes after the Pentagon estimated $37.5 billion as the bill for the war in July.
The estimate from the budget office also did not include the cost to repair US facilities damaged during the war, with most of the price tag coming from munitions expenditures, the office said. The CBO estimated the war will continue to cost the US approximately $2 billion to $3 billion per month past August 1, with higher costs estimated during periods of escalated fighting.
The office also told Congress that the war is expected to increase inflation for the first quarter of 2027, raising costs at a time Americans are growing more concerned about the economy.
