The US-Israeli war against Iran has cost the Pentagon $29 billion to date, Acting Defence Department Comptroller Jules Hurst III told the House Armed Services Committee on Tuesday afternoon, an increase of $4 billion from the $25 billion estimate Hurst delivered to the same committee on April 29. The revision reflects updated estimates of equipment repair and replacement together with operating costs through the end of April.
The Pentagon figure is materially below most outside estimates. Linda Bilmes, who led the Harvard Kennedy School's project on the Iraq and Afghanistan war costs and now runs the same exercise on the Iran war, projects total US taxpayer outlays of at least $1 trillion when veterans-care obligations, interest on the financing, and the deferred maintenance burden on US naval forces are included.
Earlier official figures bracketed the spread. Defence Secretary Pete Hegseth's March supplemental request was for $200 billion to fund the war's first six months. National Economic Council Director Kevin Hassett, briefing reporters days later, put the cost of the first six days alone at $12 billion. CBS News, citing unnamed US officials, reported last month that approximately $50 billion had been spent on the war by mid-April, with the largest single component being munitions.
The munitions question dominated Tuesday's hearing. Hurst told the committee that the Pentagon does not currently view US air-defence and precision-strike inventories as critically depleted but acknowledged that "near-term replenishment will be the most pressing budget question" through the rest of 2026. The Pentagon has placed accelerated orders with Lockheed Martin, RTX and L3Harris under emergency-authority provisions.
The supplemental funding request the Pentagon is preparing for Congress is expected to land in early June and will, defence officials told the committee, ask for between $80 billion and $120 billion. Senate Armed Services chair Tom Cotton said in a brief corridor exchange after the hearing that the upper end of that range would be "what the committee can support quickly" if it included an explicit munitions-replenishment carve-out.
The political backdrop has been the steady upward revision of cost estimates over the war's three-and-a-half months. The Pentagon's first formal figure, presented in mid-March, was $10 billion. Tuesday's $29 billion estimate is the fifth upward revision and the largest single jump. The Congressional Budget Office is due to release an independent cost estimate later in May.
The war's strategic outcome remains contested. The naval blockade of the Strait of Hormuz, in place since April 13, has held; the ceasefire signed on April 7-8 has been violated by both sides in multiple incidents since; and Trump's overnight rejection of Iran's counter-proposal as "totally unacceptable" leaves the diplomatic track unresolved. Brent crude held above $107 a barrel through Wednesday's Asian session in part on the renewed possibility of a return to "major combat operations" against Iran's nuclear sites.
