According to a WSJ investigation: 274 structures were identified as damaged across 24 military installations with a US presence. The Pentagon internally estimated damage at at least $5 billion, while a separate source said the figure could be as high as $15 billion. The damage to the US Navy's Fifth Fleet headquarters in Bahrain alone could cost about $400 million to restore. The findings also reveal that the Pentagon estimated the cost of the war at $47.1 billion by mid-October, not including the cost of repairing damaged military bases. The full financial impact of the war could be significantly higher.
