Washington: The U.S. Department of Defense (Pentagon) has informed Congress that it has spent $43.6 billion on operations related to Iran to date.

According to National Iraqi News Agency, U.S. Central Command estimates show that the Pentagon has allocated approximately $11.2 billion to cover additional operational costs through September 3, 2026. An estimated $28.1 billion is earmarked for replacing expended munitions, and about $4.3 billion has been allocated to replace lost equipment. The cost of equipment losses is subject to adjustment as further assessments are received. The estimates submitted to lawmakers do not include the potential tens of billions of dollars in costs associated with damage inflicted on U.S. bases in the Middle East by Iranian attacks.

A breakdown provided by the military shows that Army forces spent approximately $1.6 billion on “force operational readiness and basic life support for deployed personnel,” while the Navy incurred significantly higher obligations totaling $2.2 billion for “operational forces and ship and aviation operations.” The Air Force’s bill stands at $6.6 billion for “support of deployed personnel, airlift, base support, communications, and transportation.” Central Command’s breakdown also includes $10.5 million for U.S. Cyber Command, which officials acknowledged provided offensive capabilities during the early stages of the conflict.

In an estimate released earlier this week, the Congressional Budget Office projected the cost of the war with Iran to taxpayers at approximately $38 billion during the first five months of fighting. The office stated, “The cost includes replacing expended munitions and equipment lost in combat, as well as increased flight hours and rising fuel costs.” The Congressional Budget Office’s estimate aligns with the testimony given to Congress in July by Secretary of War Pete Hegseth, who stated that the war had cost $37.5 billion up to that point. According to the office, each additional month of conflict will cost at least another $2 billion to $3 billion.
