The Pentagon told members of Congress in a closed-door briefing that U.S. military operations against Iran have cost more than $11.3 billion in the first six days, a tally that excludes many pre-deployment expenses and is expected to rise as accounting continues. The figure, disclosed to lawmakers and reported by the New York Times, underscores how quickly a high-intensity strike campaign can burn through munitions, fuel and support costs even without a U.S. ground invasion.
Defense officials also disclosed that roughly $5.6 billion worth of munitions were expended in the first two days of strikes, a consumption rate far higher than public estimates earlier in the campaign. Independent estimates from the Center for Strategic and International Studies put the bill for the initial 100 hours at about $3.7 billion, or roughly $890 million per day, highlighting how different accounting methods capture different slices of the same fiscal shock.
The Pentagon’s preliminary numbers do not include costs associated with pre-positioning forces, moving equipment, or the logistics footprint established before the first airstrikes. That omission means Congress and the public may only be seeing a partial ledger, and lawmakers told by the Pentagon expect the total to climb significantly as after-action accounting draws in personnel movement, sustainment and replacement of depleted stockpiles.
Beyond the headline dollar figure, the rapid depletion of high-end munitions will pressure the U.S. defense industrial base to ramp up production at a time when supply chains remain strained. Large expenditures on precision-guided munitions, air-to-air fuel, and intelligence, surveillance and reconnaissance assets translate into accelerated demand for ordnance, ship and aircraft maintenance, and logistics — all costs that ripple into next year’s budgets.
Politically, the revelation lands awkwardly for an administration facing scrutiny from a Congress already skeptical of open-ended military commitments. Rank-and-file lawmakers will have to weigh authorizing further spending or demanding a tighter strategy to curb attrition, while the White House confronts the domestic political consequences of a costly and potentially protracted campaign.
Strategically, even if Washington avoids a large-scale ground invasion, the pandemic of strikes and counterstrikes with Israel and Iran risks turning limited kinetic action into a grinding conflict. The financial numbers are a proxy for broader strategic risk: they signal the scale at which regional conflict can drain resources, constrain U.S. options elsewhere, and raise the temperature for escalation with Tehran or its regional proxies.
