Pentagon Says First 6 Days of Iran War Cost $11.3B: Sources

The Iran war is burning through cash at a pace that stunned some senators: more than $11.3 billion in the first six days alone, according to Defense Department officials who briefed lawmakers behind closed doors this week. Three sources familiar with the session relayed the estimate to the New York Times and NBC News, while Sen. Chris Coons said he believes the real tab is already "significantly above that," noting that the estimate doesn't include everything that should be factored in: "If all you're looking at is the replacement cost for the munitions used, it's already well beyond $10 billion," he says.

The figure lands as the Trump administration prepares a supplemental funding request to cover the expanding operation, dubbed Operation Epic Fury. The fighting has killed more than 1,200 people in Iran, along with deaths in Israel, the UAE, and Lebanon, according to regional officials and aid groups; seven US troops have been killed and 140 wounded. A Pentagon spokesperson declined to discuss the briefing and said the final cost won't be known until the mission ends—a timeline that remains murky, as President Trump has alternated between predicting the war will end "very soon" and backing his defense secretary's suggestion that it's only just beginning.
