Pentagon Watchdog Details Heavy US Losses, Missile Shortages, and Facility Damage in First Review of Iran War

A Pentagon official watchdog released a special report on Monday detailing the first formal accounting of US equipment and facility losses stemming from the Iran war. Covering the period from the start of the conflict on February 28 through June 30, the inspector general cited communications with US Central Command to report that Iranian strikes damaged and destroyed hundreds of buildings and structures at US bases across Kuwait, Bahrain, Qatar, UAE, Saudi Arabia, Iraq, Oman, and Jordan during the opening months of the war.

The report also acknowledged the depletion of key US munition stockpiles. Previous reporting by CNN highlighted the destruction of critical US assets, including missile defense radar installations, early in the conflict. These Iranian strikes prompted significant operational adjustments for US troops in the region, with CENTCOM shifting personnel, assets, and storage facilities in response to attacks from Iran and its proxy forces. Among these moves was the withdrawal of Army medical evacuation helicopters from Iraq and Kuwait, resulting in ground transport to local treatment facilities for most medical evacuations.

Significant challenges in establishing adequate naval bases and support ports arose from the destruction of the Navy's regional hub in Bahrain, which acting Navy Secretary Hung Cao recently stated Iran blew apart. Consequently, the distant Indian Ocean island of Diego Garcia became a sea logistics hub, extending resupply cycles to between 14 and 18 days. These logistical hurdles, along with intermittent supply shortages and regional mail system interruptions, compounded difficulties for US sailors during extended deployments in the Persian Gulf aimed at supporting airstrikes on Iran and blockading its ports.

Discussions among military and intelligence community officials suggest that alterations to the US Middle East footprint might become permanent once the war concludes, with potential lasting cuts to regional personnel and facilities.

Produced in cooperation with the State Department's and US Agency for International Development's inspector general offices, the report also examined regional US diplomatic activities. Iranian attacks on US diplomatic facilities caused approximately $184 million in damage, though cost estimates for military sites were omitted. Compounds in Iraq, Kuwait, Saudi Arabia, and the United Arab Emirates faced continuous assaults. In early March, the US Embassy in Riyadh sustained extensive damage from two Iranian drones, impacting the compound's CIA station. A concurrent drone strike targeted the US consulate in Dubai, damaging a utility building, while US Secretary of State Marco Rubio noted the drone hit a parking lot adjacent to the chancellery building. Furthermore, the US Embassy in Kuwait suspended operations entirely in March following drone strikes before resuming emergency services in late June.

A senior State Department official reported over 600 attacks against US facilities in Iraq, which accounted for the most costly damage at roughly $157 million. Between February 23 and June 30, up to 3,500 diplomatic personnel evacuated the region due to ordered or authorized departures across most US posts. Diplomatic facilities in Bahrain, Iraq, Jordan, Qatar, Saudi Arabia, and the United Arab Emirates faced ordered departures for non-emergency personnel and family members within weeks of the February outbreak. Although restricted operations largely remain in place, some diplomats and family members have begun returning to the region.
