Pentagon officials informed Congress that military operations against Iran cost approximately $11.3 billion during the first six days of conflict, according to testimony before the Senate Appropriations Subcommittee on Defense.

Defense Department representatives briefed senators on the financial impact of the military engagement during a closed-door session with the defense subcommittee. The $11.3 billion figure represents direct costs incurred during the initial phase of operations.

At least one senator who attended the briefing suggested the actual costs may be higher than the Pentagon's reported figure. The lawmaker indicated that the $11.3 billion estimate did not include certain expenses such as munitions replacement costs, which could significantly increase the total financial impact.

The briefing comes as Congress weighs funding requests and examines the fiscal implications of ongoing military operations. Defense spending oversight has become a key focus for appropriators as they consider future budget allocations.

The Pentagon has not publicly released detailed breakdowns of operational costs, and it remains unclear what specific expenses were included in the $11.3 billion calculation presented to senators during the subcommittee session.
