Pentagon figures show US spending on Iran war climbs past $47 billion

The financial toll of the American military campaign in Iran has surpassed $47 billion, marking an increase of over 25 percent compared to assessments made earlier in the summer, according to internal Defense Department figures obtained by Reuters.

The updated figure reflects a notable climb from the $37.5 billion projection issued in July by Defense Secretary Pete Hegseth. The unreleased estimates outline the direct operational spending required for the conflict, though the Pentagon did not immediately provide a formal response regarding the findings.

Replenishing military stockpiles makes up the largest portion of the expenditure. The department projects needing over $29 billion to replace ammunition and precision ordnance used throughout the campaign. An additional sum exceeding $6 billion has been earmarked to cover lost platforms and hardware, including numerous unmanned aircraft downed during combat. However, the data does not provide a comprehensive accounting of the potentially massive sums required to rebuild American military facilities struck by Iranian missile and drone bombardments.

President Donald Trump initiated the military offensive alongside Israel in February, forecasting a brief engagement. Early tactical planning aimed to neutralize Iranian defensive networks using costly precision-guided munitions, which was intended to allow subsequent strikes to rely on more abundant, less expensive ordnance such as JDAM gravity bombs.

That trajectory shifted after an April ceasefire enabled Iranian forces to clear buried infrastructure and reactivate concealed missile, drone, and air defense assets. Since the truce collapsed, at least four American military personnel have been killed, including Sergeant Angel Rampersad, who died following a strike in Jordan.

Following the breakdown of the truce, the administration established a maritime blockade aimed at cutting off Iranian petroleum exports. Trump has suggested that intensive offensive operations could resume, and anonymous American officials noted that military planners have prepared options should the administration order renewed strikes.

The disclosure arrives at a sensitive moment for the White House, with the November 3 midterm elections approaching to decide the balance of power on Capitol Hill. Republicans, who maintain slim majorities in both legislative chambers, are navigating public dissatisfaction with the campaign alongside the economic repercussions of elevated international energy prices, which have weighed on the administration's approval ratings.
