Pentagon Funds Iran War from Base Budgets as Congress Withholds $67B Supplement

Key points

• Congress has not appropriated funds specifically for the Iran war, forcing the Pentagon to use base budgets for training and maintenance.
• The Congressional Budget Office estimates the war has cost $38.1 billion through August 1, with monthly costs of $2-3 billion.
• The Pentagon’s inspector general reported $33.4 billion in costs through June 30, excluding infrastructure repairs and economic fallout.
• The White House requested $67.1 billion in supplemental funding, but only $42.3 billion is directly related to the conflict.
• The war has depleted missile stockpiles, damaged hundreds of military and diplomatic buildings, and resulted in at least 18 U.S. service member deaths.

Background

The Iran war began in February 2026, with combat operations launched by President Trump. The conflict has been costly, with estimates ranging from $25 billion in April to $38.1 billion in August. The war has also damaged U.S. military and diplomatic facilities in the Middle East, with Iranian strikes hitting bases in Kuwait, Bahrain, Qatar, UAE, Saudi Arabia, Iraq, Oman, and Jordan. The Pentagon has been assessing its military footprint in the Middle East as the war winds down, considering whether to rebuild strike-damaged bases and where to relocate troops.

How outlets are covering it

The Center Square and Military Times report that the Pentagon is funding the war from base budgets, while the Congressional Budget Office estimates the cost at $38.1 billion. MS NOW argues that the $38 billion figure is a minimum, excluding costs like infrastructure repairs and economic fallout. Responsible Statecraft criticizes the administration for claiming 'treasonous' weapons shortages, while the Pentagon disputes claims of munitions shortages. Democrats argue the Pentagon does not need the supplemental funding, while Republicans defend the request as necessary for rebuilding priorities.

Why it matters

The Iran war is costing the U.S. tens of billions of dollars, with no dedicated appropriation from Congress. The Pentagon is using base budgets for training and maintenance, which may delay weapons modernization and other activities. The war has also depleted missile stockpiles and damaged military and diplomatic facilities, raising concerns about U.S. military readiness and the economic impact on American consumers.

What to watch

Congress is expected to vote on the $67.1 billion supplemental funding request, while the Pentagon continues to fund the war from base budgets. The CBO estimates the war will cost an additional $2-3 billion per month, with costs potentially increasing if hostilities continue. The Pentagon is also assessing its military footprint in the Middle East, considering whether to rebuild strike-damaged bases and where to relocate troops.
