Iranian military strikes on U.S. diplomatic facilities across four Gulf nations have caused an estimated $184 million in damage, according to a newly released Pentagon Inspector General report.

The 44-page report, made public Monday, is the first watchdog assessment since the United States and Israel launched the war in late February.

The affected diplomatic posts are located in Iraq, Kuwait, Saudi Arabia, and the United Arab Emirates, covering a broad swath of America’s Gulf presence.

Iraq sustained by far the heaviest toll, with damages exceeding $157 million, reflecting the scale and frequency of attacks on U.S. facilities there.

The U.S. mission in Iraq alone experienced over 600 Iranian attacks, underscoring the sustained and concentrated nature of Tehran’s military campaign.

Kuwait suffered more than $14 million in damages, while Saudi Arabia recorded $11.5 million in losses, and the UAE diplomatic post sustained $125,000 in damage.

Beyond diplomatic facilities, the watchdog report confirmed that U.S. military bases, aircraft, and other assets within the U.S. Central Command theater also suffered damage.

The Pentagon has estimated total war costs at $33.4 billion for the period from February 28 to June 29, a figure that does not account for infrastructure repair expenses.

Defense Secretary Pete Hegseth told Senate lawmakers in July that the Iran war’s estimated cost had already climbed to $37.5 billion.

The State Department separately reported incurring $113 million in war-related costs as of June 2, noting that ongoing damage assessments mean that figure is likely to rise.

The human cost of the conflict has been significant, with 18 U.S. service members killed and approximately 800 wounded over the more than six months of fighting.

Around 50,000 American troops remain deployed to the region, with the Trump administration yet to present a clear exit strategy from a conflict that has grown deeply unpopular.

Top administration officials have at times downplayed the extent of damage caused by Iranian one-way attack drones and missiles, including strikes on Naval Support Activity Bahrain, the headquarters of U.S. Naval Forces Central Command and the U.S. Fifth Fleet.

The Navy has used Naval Support Activity Bahrain as its primary logistics hub in the Middle East, and officials are now weighing options for the base, including whether it should be repaired or repurposed.
