Defense Sec says war cost $37.5 billion seeks $67 billion

Defense Secretary Pete Hegseth told lawmakers on July 21, 2026, that the ongoing U.S. military conflict with Iran has cost $37.5 billion to date, a significant increase from a $29 billion estimate provided in May. Hegseth delivered the updated cost assessment during a contentious hearing before the Senate Appropriations Committee, where he and Chairman of the Joint Chiefs of Staff Gen. Dan Caine defended a request for approximately $67 billion in supplemental funding specifically for the war effort. The hearing was repeatedly interrupted by anti-war protesters.

The defense secretary argued the funding is urgently needed to replenish depleted weapons stockpiles, expand munitions production, and cover military pay and operations through the end of the fiscal year on September 30. He warned that without the funds, military training would face curtailment. The $67 billion request is part of a broader $95 billion Republican budget package advancing in the House, which also includes aid for farmers and funding for voter law changes. The package is expected to move through a reconciliation process, with a House vote anticipated this week.
