US expenditures on the war with Iran exceeded 47 billion dollars.
Such data from the Pentagon is provided by Reuters and Hill. The largest amount of money was spent on perfect ammunition renewal - over 29 billion dollars, and it is estimated that more than 6 billion will replace destroyed or damaged equipment. However, the current estimate does not fully take into account the damage to American facilities in the Middle East that have been subject to Iranian missile and drone attacks, so the final cost of the campaign may be higher.
