Pentagon Report: Iranian Strikes Damaged U.S. Bases Across 8 Middle East Countries

A Defense Department Office of the Inspector General report released in September 2026 documents damage to U.S. military and diplomatic facilities from Iranian strikes across eight Middle Eastern countries during the period April 1–June 30, 2026. U.S. Central Command confirmed that Iranian attacks damaged and destroyed hundreds of buildings and structures at bases in Kuwait, Bahrain, Qatar, the United Arab Emirates, Saudi Arabia, Iraq, Oman, and Jordan. U.S. diplomatic facilities in four countries sustained an estimated $184 million in damage, with Iraq's diplomatic mission bearing the heaviest toll at over $157 million following more than 600 attacks on that country's facilities. Additional diplomatic damage was recorded in Kuwait ($14 million), Saudi Arabia ($11.5 million), and the UAE ($125,000).

U.S. and allied air defenses intercepted more than 6,000 Iranian drones and 1,500 ballistic missiles, but some munitions breached defenses, causing casualties and infrastructure damage. The report documented dozens of American aircraft destroyed or damaged, including four F-15E fighters, one A-10 ground-attack jet, four AH-6 helicopters, one AH-64 Apache, one MH-60 helicopter, one MQ-4C surveillance drone, and as many as 30 MQ-9 Reapers (valued at over $30 million each). As of late August, 18 U.S. military personnel had been killed, with casualty figures rising to 774 wounded by that date. A U.S. naval logistics hub in Bahrain was targeted with ballistic missiles and drones, forcing the Pentagon to redirect supply operations to Diego Garcia in the Indian Ocean, creating logistics cycles exceeding two weeks and affecting warship resupply, including the USS Abraham Lincoln aircraft carrier.

The Pentagon estimated the operational cost of what the report refers to as Operation Epic Fury at $33.4 billion as of June 29, comprising $22.3 billion in expended munitions, $3.7 billion in equipment losses, and $7.4 billion in costs beyond U.S. Central Command's normal operating expenses. The report noted that these figures do not include costs for repairing or reconstructing damaged military infrastructure, as the Defense Department stated it had not yet determined the U.S. regional military posture, construction methods, or the extent of allied and partner cost-sharing. Congress did not appropriate dedicated funds for the operation, requiring the Pentagon to draw from existing military service budgets for training and maintenance. U.S. Transportation Command conducted over 1,500 missions in support of operations, with airlift surging to 30–40 daily missions into the region at peak times, costing nearly $2.4 billion as of June 30. The report flagged anticipated delays in reimbursement to Transportation Command as service funding faces depletion without supplemental appropriation.

According to the Russian-language source Финансы Mail, a June 2026 memorandum of understanding signed by Washington and Tehran stipulated an immediate cessation of hostilities across all fronts, including Lebanon. However, the same source reports that on the night of July 8, the United States resumed large-scale strikes against Iran, citing alleged violations of the accord concerning the Strait of Hormuz. The report represents among the first official comprehensive assessments of the conflict's material impact since military operations commenced on February 28, 2026.
