The Defense Department’s inspector general revealed Monday that the United States is facing a shortfall in ammunition as a result of its costly war in Iran.
In a first-of-its-kind mandatory report to Congress, the inspector said that between Feb. 28 and June 30, Operation Epic Fury (OEF) had an estimated cost of $33.4 billion, with $22.3 billion of that spent on munitions alone.
“The munitions expenditure on OEF has resulted in strategic inventory shortfalls and revealed industrial base bottlenecks for munitions resupply,” the report states.
It also lists American military assets lost in the war, including four F-15s destroyed, one F-35 damaged, seven KC-135 tanker aircraft damaged and up to 30 MQ-9 Reaper drones destroyed.
U.S. military ready “for any contingency”?
President Trump has repeatedly brushed off concerns of depleted weapons supplies during the six months of war in the Middle East, saying just two weeks ago that the U.S. has “virtually unlimited amounts of Mid to High Grade Ammunition, far more than we could ever use for this, or for any other War (which is highly unlikely!), that could improbably take place. In addition, we are producing Munitions at levels never seen before. We are stockpiling and preparing for any contingency that could happen.”
Mark Cancian of the Center for Strategic and International Studies, when asked if the U.S. has enough weapons to see the Iran war through, told CBS News, “for a war against Iran, the answer is yes. The problem is a war against China. We might be able to provide enough munitions for a month, but getting on to month two or month three or four, that’s a great challenge.”
Top Pentagon officials had also denied claims of U.S. munition shortages ahead of the inspector general’s report dropping on Monday, but Defense Secretary Pete Hegseth has been urging the defense industry to increase weapons manufacturing, which Lockheed Martin’s Tim Cahill, the head of the company’s missile division, describes as “controlled chaos.”
“CBS Sunday Morning” was recently granted access to Lockheed Martin’s production facility in Arkansas to see work on the latest model of the Patriot air defense missile. The weapon is designed to shoot down incoming ballistic missiles, but each one costs around $4 million, and Lockheed Martin is currently producing 750 of them a year.
Non military Iran-war related costs for U.S. taxpayers
Additionally, the inspector general’s report says the U.S. State Department spent $79.2 million responding to “contingencies stemming from the Iran conflict, such as evacuation-related expenses for State personnel and their family members, U.S. citizens, and eligible third-country nationals.”
The report put the price tag to repair “physical damage from Iranian strikes” to U.S. diplomatic facilities in Iraq, Kuwait, Saudi Arabia and the UAE at approximately $184 million.
The report notes also that “Iranian strikes damaged and destroyed hundreds of buildings and structures at U.S. bases in Kuwait, Bahrain, Qatar, UAE, Saudi Arabia, Iraq, Oman, and Jordan,” but it does not include costs estimates and says it’s not yet clear if all the bases will be repaired, or who would foot the bill.
In April, a Pentagon official estimated in testimony on Capitol Hill the cost of Operation Epic Fury at about $25 billion, but U.S. officials familiar with internal assessments told CBS News soon after that the true price tag of the Iran war at the time was closer to $50 billion.
