Hidden costs of US Iran war push total far beyond $25bn Pentagon claim
Al Mayadeen | April 30, 2026
The Pentagon’s declared $25 billion cost of the war on Iran is likely a significant understatement of the war’s true financial burden, Bloomberg reported, citing analysts. Senior US defense officials disclosed the figure during testimony at a contentious congressional hearing on Wednesday, outlining the total cost incurred so far.
Calculations by Bloomberg, based on Pentagon data, suggest that the cost of certain munitions, destroyed equipment, and operational expenses alone amounts to around $14 billion. This includes $8 billion for munitions, $5 billion to replace lost aircraft and damaged equipment, and approximately $1 billion in operational costs for deploying two aircraft carriers and 16 destroyers over 39 days of near-continuous strikes.
The estimate does not account for the cost of repairing damaged facilities across the region, such as the US Navy’s Fifth Fleet headquarters in Bahrain, which has been repeatedly targeted in Iranian attacks. It also excludes the operational costs of all ships and aircraft involved in the military buildup prior to February 28, as well as those currently engaged in the ongoing blockade.
Pentagon figure represents narrow estimate, omits lots of costs
“It is clear that the Pentagon’s $25 billion figure represents a narrow estimate of the cost of waging war,” said Kelly Grieco, a senior fellow at the Stimson Center. “It doesn’t even include damage to bases, broader operational costs, or the Pentagon’s rising fuel bills.”
Earlier this month, Senator Richard Blumenthal told Bloomberg Television that even estimates presented to him of $2 billion per day were “a low number.” Meanwhile, the Center for Strategic and International Studies has estimated that the cost of munitions alone could reach approximately $25 billion.
During the hearing, Acting Pentagon Comptroller Jules Hurst said the $25 billion figure includes both expended munitions and operational costs but declined to provide a detailed breakdown. His remarks prompted a heated exchange between War Secretary Pete Hegseth and Representative Maggie Goodlander, a Democrat from New Hampshire, who repeatedly pressed for greater transparency.
“It is gross negligence to sit here and be unable to justify spending billions of dollars,” Goodlander said.
US losses add billions to the bill
The United States has reportedly lost dozens of aircraft during combat operations, including MQ-9 Reaper drones, F-15E strike fighters, an E-3 airborne warning and control aircraft, KC-135 aerial refueling tankers, one A-10 attack aircraft, and two MC-130J multi-mission transport planes.
Replacing these systems is expected to cost billions of dollars, while damaged or destroyed radar systems, each worth hundreds of millions, will add further to the total.
Operating costs have also mounted significantly. Aircraft carriers cost around $4.9 million per day to run, while destroyers cost approximately $600,000 daily. A carrier air wing adds another $3.8 million per day.
According to analysis by Bloomberg Economics Defense Lead Becca Wasser, the 39 days of combat alone would run about $1 billion for just two carriers and their air wings, and 16 destroyers.
Iran has launched more than 1,850 ballistic missiles at targets across the region, requiring the use of roughly 4,000 interceptor missiles in response, according to the report. While the PAC-3 missile system remains the backbone of ballistic missile defense in the region, most interceptor launches were carried out by Gulf states. Standard missile defense doctrine typically requires firing at least two interceptors per incoming target, further driving up costs.
