The Center for Strategic and International Studies (CSIS) published an assessment putting the cost of the U.S. military campaign against Iran at $34-42 billion, according to a report. The estimate includes $26.1 billion for munitions, with $18.5 billion allocated to air defense systems such as Patriot and THAAD and $7.5 billion for ground strike munitions.
The CSIS estimate falls within the range of previous official figures. Defense Secretary Pete Hegseth stated on July 21 that the war had cost $37.5 billion, and earlier Pentagon assessments put the figure at $40 billion, as The Zioneer reported. The new estimate from the Washington-based think tank provides a detailed breakdown of munitions expenditure: $18.5 billion on air defense interceptors (Patriot and THAAD) and $7.5 billion on ground strike munitions, totaling $26.1 billion in ammunition alone. The overall cost range of $34-42 billion is consistent with the $37.5 billion official figure, though it falls short of internal Pentagon estimates that reportedly reached $100 billion. The report did not specify the time period covered by the estimate.
