US burns through $30 billion in military operation against Iran

The United States spent approximately $30 billion on its military operation against Iran, the director of the Office of Management and Budget (OMB), Russell Vought, said during a congressional hearing on June 30.

“We’ve spent about $30 billion,” Russel Vought told the House Appropriations Committee. 

His remarks came after acting Pentagon comptroller Jules Hurst stated in May that US expenditures related to the operation against Iran had approached $29 billion.

The US conducted large-scale military strikes against Iran as part of Operation Epic Fury, which began on February 28, 2026, in coordination with Israel. 

These operations targeted Iranian nuclear sites, missile capabilities, and other military assets following escalated tensions and failed negotiations.

Early phases of the conflict saw intensive use of munitions, air and naval operations, and missile defences, with costs driven heavily by expensive weapons systems like Tomahawks, Patriots, and aircraft operations. Pentagon estimates placed initial expenditures in the range of billions within the first week to month, reflecting high daily operational tempos that later moderated.

Broader impacts included equipment losses, base repairs in the region, and long-term munitions replenishment challenges, contributing to supplemental funding requests from Congress.
