The US military campaign against Iran has already cost more than $11.3 billion in just six days, according to officials who briefed lawmakers on the escalating conflict. The staggering figure, provided by a person familiar with the matter, represents the most detailed assessment yet of the financial toll of President Donald Trump's military operations.

The rapid expenditure underscores the immense costs of modern warfare, with expenses likely covering missile strikes, naval operations, and troop deployments across the region. Defense officials have been working to provide Congress with real-time updates on the financial impact as the conflict intensifies. The six-day cost exceeds the annual budgets of many government agencies.

This level of spending in such a short timeframe highlights the economic strain of sustained military operations. As the conflict continues, the mounting costs will likely face increased scrutiny from lawmakers concerned about the impact on federal budgets and the broader economy. The Trump administration now faces pressure to justify these expenditures as the war's duration and scope remain uncertain.
