US Military Campaign Against Iran Costs $3.7 Billion in First 100 Hours, CSIS Reports

The US military campaign against Iran, dubbed Operation Epic Fury, has cost approximately $3.7 billion in its first 100 hours, averaging about $891 million daily, according to analysis by the Centre for Strategic and International Studies (CSIS). Most expenses, primarily for replacing advanced munitions like Tomahawk missiles and precision rockets, were unbudgeted, potentially requiring additional Pentagon funding. Analysts warn this financial burden may pose political challenges for the Trump administration and affect public support amid rising domestic inflation and fuel prices.
