The US Army has spent over $47 billion (about 42 billion euros) so far to carry out the Iran war, more than 25 percent higher than the US Department of Defence assessment in July, according to Pentagon data received by Reuters.
The Pentagon did not immediately respond to a request for a comment on his assessment, which has not been publicly divided.
The discovery concerning the growing cost of war in Iran comes as the Republicans face the political consequences of the conflict ahead of the November 3rd elections that will determine the control of Congress for the next two years.
The impact of war on global energy costs has affected support for republican candidates and has damaged support for President Donald Trump.
The Republican Trump Party holds a narrow majority in both chambers of Congress.
The Pentagon’s latest assessment was linked to operational war costs, at a cost projected by more than 29 billion dollars to replace the used ammunition in conflict.
More than $6 billion would be needed to replace military equipment and so-called platform losses, which include the loss of planes, including many fears lost during the war.
Trump launched the fight against Iran along with Israel in February, predicting that the conflict would last a short time.
Trump’s initial strategy in the fight against Iran was initially focused on the use of expensive and high-precise missiles to bomb Iran’s defence so that it could later use less costly ammunition, including air-propelled JDAMs, which are numerous.
But a ceasefire in April gave Iran time, restoring some Iranian defences to function, as well as rockets and fears they had been elusive.
Trump has since imposed a naval blockade on Iran to deprive it of revenues from oil exports and has hinted out the possibility of restarting combat operations after mid-term elections.
American officials, speaking on condition of anonymity, say the Pentagon is planning to resume fierce fighting if ordered to do so.
The Pentagon’s latest assessment is compared to the assessment of Defence Secretary Pete Hegseth, made in July, under which the cost of war would be $37.5 billion.
Although the figures include a series of operational costs from air operations to cyber-support, US Army assessments of the cost of a war with Iran did not clearly reflect the great spending expected to be needed to repair damage on American bases, caused by Iranian missile attacks and fears. /Telegraph/
