US spends $6 billion in first week of Iran war, Pentagon officials say

The first week of America's military campaign against Iran has carried a staggering $6 billion price tag, Pentagon officials disclosed to Congress, with the bulk of spending consumed by munitions and sophisticated defensive systems. According to The New York Times, approximately $4 billion of the total was dedicated to munitions expenditures and advanced interceptors designed to neutralize incoming Iranian missiles. The figures emerged during congressional discussions this week, where senior defense officials outlined the intensive operational tempo required to strike Iranian targets while simultaneously defending US assets and regional allies from Tehran's retaliatory barrages. The rapid expenditure has sparked concerns about sustainability and the potential need for additional appropriations to continue the campaign. Military Gains and Remaining Threats Adm. Brad Cooper, head of US Central Command, briefed lawmakers on the campaign's effectiveness, revealing that American forces have struck approximately 4,000 Iranian targets including missile launchers, naval vessels and air defense systems. These strikes have significantly eroded Tehran's ability to project power, with ballistic missile launches dropping 90% since the first day of fighting and drone attacks declining by 83%. Despite these gains, Cooper cautioned that Iran retains formidable military capabilities, including an estimated 50% of its missile program. The assessment suggests that while the opening week delivered punishing blows to Iranian forces, the conflict is far from over and Tehran retains substantial capacity to continue its retaliation. Budget Concerns and Supplemental Requests The eye-watering first-week costs have drawn scrutiny from both sides of the political aisle, with critics questioning the sustainability of current operational tempos. Lawmakers expressed particular concern about the consumption rates of expensive interceptors, some costing millions of dollars each, warning that current usage could strain the US defense industrial base and create shortfalls in other strategic theaters. Congress is now bracing for a supplemental budget request from the administration in the coming weeks, as Pentagon officials emphasize the need to maintain momentum against Iranian capabilities while balancing long-term national defense priorities. The funding debate promises to be contentious, with fiscal hawks demanding accountability while national security advocates argue that the costs of inaction would be far higher. Wider Conflict Context The eye-watering expenditures come amid a conflict that has already claimed more than 1,200 Iranian lives, including Supreme Leader Ali Khamenei, over 150 schoolgirls and numerous senior military officials since Feb. 28. Tehran has responded with sweeping barrages targeting US bases, diplomatic facilities and military personnel across the region, as well as multiple Israeli cities, forcing expensive defensive responses from American and allied forces. The widening war has raised alarms about global energy security, with maritime traffic through the Strait of Hormuz dropping sharply. The strategic waterway carries approximately 20 million barrels of oil daily, and any sustained disruption would have immediate consequences for world markets already jittery from the conflict's expansion. Strategic Implications The $6 billion first-week figure represents only the opening chapter of what could become one of the most expensive military engagements since the Iraq War. As the conflict expands across multiple fronts and Iran continues launching retaliatory strikes, the financial burden on American taxpayers will only grow, potentially reaching hundreds of billions if the war continues at current intensity. Pentagon officials argue the investment is necessary to permanently degrade Iran's capacity to threaten regional stability and American interests. But with Iran still possessing half its missile arsenal and the conflict showing no signs of de-escalation, the path forward remains uncertain both militarily and fiscally.
