Pentagon Seeks $1.5 Trillion as Iran War Tab Hits $37.5 Billion and Grows

A War Bill That Keeps Climbing

The Iran war has now stretched into its fifth month , and the price tag is rising fast. Under questioning before the Senate Appropriations Committee on Tuesday, Defense Secretary Pete Hegseth said the administration estimates the Iran conflict has cost $37.5 billion so far. That figure, however, may only tell part of the story — experts told CNN the bill is likely much higher.

Several times, protesters interrupted Hegseth's opening remarks, which came days after the Pentagon announced that three more American service members had died in the conflict, bringing the death toll to 17, and that more than 100 have been injured since early July. Nearly 450 have been injured since the start of the war. Against that backdrop, Hegseth made his case for a massive injection of new funds, warning Congress that delay would have real consequences. "Without these funds, we face critical shortfalls," Hegseth testified.

What the Pentagon Is Asking For

The Trump administration sent Congress an $87.6 billion supplemental budget request last month, including $67.1 billion for the Pentagon. Both Hegseth and Joint Chiefs Chairman Gen. Dan Caine reiterated the administration's position that it needs $1.5 trillion, plus the supplemental, to be fully funded and address military needs around the world. The supplemental request covers a wide range of needs, from replacing depleted weapons stocks to expanding production lines. Hegseth said funding was needed "to expand production lines and accelerate delivery of high-demand munitions," including solid rocket motors, JDAMs, hypersonics, and counter-drone capabilities.

The Pentagon chief also pointed to a pending budget crunch, saying that "training in the future would have to be curtailed if we do not get our budget needs met and met urgently." Democrats on the committee pushed back hard. Sen. Patty Murray of Washington, the top Democrat on the committee, warned that the conflict is now "spiraling out of control again," saying her colleagues "cannot and will not support rubber-stamping a request to bankroll this war." Even some Republicans expressed frustration: Republican Sen. John Kennedy told reporters that Congress and the American public need "some straighter answers" from the Pentagon, including an explanation of "how we're going to get out" and how the U.S. will "undermine Iran's ability to get a nuclear weapon."

Pickaxe Mountain Looms Over the Conflict

Trump claimed on Tuesday that the U.S. will be striking Iran's Pickaxe Mountain "probably pretty soon," amid reports that Tehran has moved nuclear centrifuges, and possibly even enriched uranium, to the secretive underground enrichment site. Israeli intelligence believes Iran moved part of its enriched uranium stockpile and advanced enrichment centrifuges to Pickaxe Mountain after last June's attacks, during which Israel struck three key Iranian nuclear facilities — Natanz, Isfahan, and Fordow — and killed a number of top scientists involved in nuclear research and development.

Its depth makes Pickaxe one of Iran's most difficult nuclear facilities to attack — the facility is estimated to sit roughly 300 to 450 feet beneath a granite mountain. It is not clear whether the U.S. military has bombs that can penetrate the rock above the deep underground facility, though a U.S. strike could still do damage to the site and block its entrance tunnels. Tehran warned that any U.S. attack on Iranian nuclear facilities would be treated as an expansion of the war in the region.

A Fork in the Road

U.S. Central Command has bombed Iranian targets for 11 straight nights, including military operations centers, drone storage facilities, and military logistics infrastructure, as it seeks to weaken Iran's ability to control commercial shipping in the Strait of Hormuz. Meanwhile, U.S. officials say Trump is nearing a fork in the Iran war, weighing two options: pursuing a new 10-day ceasefire aimed at reopening the Strait of Hormuz — urged by Qatar, Egypt, Pakistan, and other regional mediators — or launching a massive joint military campaign with Israel to try to force Tehran to capitulate.

With the Pentagon's budget running thin, American casualties mounting, and a potential new strike on a hardened nuclear site on the horizon, the financial and strategic decisions being made in Washington this week will shape how — and how long — this conflict continues. The $1.5 trillion question isn't just about dollars. It's about what kind of war America is prepared to fight, and for how long.
