Iran War Has Cost $37.5 Billion So Far, Hegseth Tells Senate

The U.S. war against Iran has cost $37.5 billion so far, Defense Secretary Pete Hegseth told lawmakers during a Senate Appropriations Committee hearing . He described the figure as the Pentagon’s latest estimate while defending President Donald Trump’s request for an $87.6 billion supplemental funding package.According to Hegseth, about $67.1 billion of the request would fund the Pentagon’s Iran war operations, replenish munitions, strengthen military readiness, and support other defense priorities.

The hearing lasted more than three and a half hours and exposed deep political divisions over the cost, objectives, and future of the Iran conflict. Democratic lawmakers questioned the administration’s military strategy and the need for additional funding, while Republicans largely supported the request but sought greater clarity on the campaign’s long-term direction. The exchanges highlighted growing scrutiny of the war as Congress prepares to debate additional defense spending.

Hegseth Defends $87.6 Billion War Funding Request

Hegseth urged Congress to approve the administration’s $87.6 billion national security supplemental request, arguing that the funding is essential to sustain military operations and preserve U.S. readiness. He said the package would replenish weapons and ammunition used in the conflict, rebuild depleted stockpiles, and accelerate production of JDAM precision-guided bombs, solid rocket motors, hypersonic weapons, and counter-drone systems. Hegseth and Gen. Caine also stressed that the investment is needed to prepare the military for future security challenges, not just the current conflict.

Democratic lawmakers, however, questioned why additional funding was necessary after Congress had already approved nearly $150 billion in defense spending through the Republican-backed “Big Beautiful Bill.” Pentagon officials replied that much of that money had already been committed to other defense programs and was unavailable for the Iran campaign. Hegseth warned that delaying the package could affect military training, readiness, and future defense operations.

Senate Hearing Turns Combative Over Iran War Objectives

The debate shifted from funding to the broader purpose of the war as Democratic senators questioned whether the administration had achieved its stated military goals. Sen. Brian Schatz argued that Iran’s missile capability, nuclear ambitions, and broader regional threats had not been fully eliminated. He also questioned whether the conflict had produced measurable strategic gains. Hegseth rejected those criticisms and said the administration’s objective is narrowly focused on preventing Iran from acquiring a nuclear weapon, not pursuing regime change or repeating prolonged conflicts like Iraq and Afghanistan.

The hearing ended with a heated political confrontation. Sen. Gary Peters called the campaign a failure and warned that the United States risked entering another “forever war.” The hearing also highlighted the conflict’s growing human cost, with 17 U.S. service members killed and more than 100 wounded since the war began. Congress is now expected to consider a separate $95 billion defense package, ensuring that both the war’s cost and its long-term strategy remain at the center of the national debate.
