The US Department of Defence has disclosed that military engagements and operations related to Iran have incurred expenses totalling $45.1 billion, marking a substantial financial commitment outlined in official communications to the US Congress.

The Pentagon's estimate, provided as part of routine defence appropriations briefings, reflects direct operational costs associated with the military activities. However, defence officials acknowledged that the total figure does not encompass all related expenses, particularly indirect costs and the restoration of damaged facilities that may have resulted from the operations.

The disclosure underscores the significant fiscal impact of the prolonged military tensions between Washington and Tehran, which have escalated periodically over the past two decades. The costs span equipment deployment, personnel expenses, and operational maintenance across multiple theatres in the Middle East and surrounding regions.

Defence analysts note that the absence of comprehensive accounting for indirect expenses and infrastructure repairs means the actual total financial burden could be considerably higher. Congress continues to scrutinise defence spending related to Iran operations as part of broader oversight of military expenditures in the region.

The Pentagon's figures are expected to inform ongoing congressional debates regarding defence budgeting and resource allocation for Middle Eastern security operations.
