The cost to the US budget of operations against Iran reached approximately $47.1 billion between February 28 and October 16. The US Department of Defense disclosed the figure to Congress.
The total cost increased by $3.5 billion in the approximately six weeks since the Pentagon's previous estimate. More than 60 percent of the spending was used to purchase bombs, missiles and other munitions.
Munitions received the largest share
Munitions expenses rose to $29 billion, while stocks of some critical weapons, including Patriot air defense missiles, declined. US military units in Asia and Europe provided ammunition supplies to sustain the operations.
The US sent more than 50,000 service members to the region. The Air Force spent $7.6 billion on fighter aircraft and bomber fleets, while the Army spent $2.1 billion on its activities.

The deployment of more than 20 Navy warships, including aircraft carriers, to the region cost $1.5 billion. A total of $6.1 billion was allocated to replace military aircraft and other equipment that was damaged or destroyed.
Other costs of the operations
The deployment and support of special operations forces in the region received $645 million, while $92.2 million was budgeted to transport supplies and equipment. A total of $14 million was allocated for cyber support operations and $24.5 million for medical support.
Eighteen US service members were killed and more than 860 were wounded in the operations.
The US administration requested an additional $70 billion in funding to procure new weapons and personnel. The Pentagon has not yet responded to a request for comment on the matter.
