Summary

Reports on Operation Epic Fury describe a costly and damaging U.S. war with Iran that has depleted important munitions stocks, exposed defense-industrial bottlenecks and damaged military and diplomatic facilities across the Middle East. The Pentagon inspector general estimated costs of $33.4 billion through late June, including roughly $22.3 billion for combat munitions, while the Congressional Budget Office placed costs at about $38 billion through August 1 and projected an additional $2 billion to $3 billion per month if fighting continues. U.S. forces reportedly lost or damaged numerous aircraft and drones, while Iranian strikes affected hundreds of structures and forced changes to regional logistics. Replacing interceptors, missiles and other advanced weapons could take years, raising concerns about readiness for a potential future conflict with China. The findings contradict President Donald Trump’s claims that U.S. ammunition supplies are virtually unlimited, although Pentagon officials maintain that current operational needs can still be met. Separately, Iranian Foreign Minister Abbas Araghchi’s planned visit to China underscores Beijing’s diplomatic and strategic interest in the conflict, including calls for a ceasefire and reopening the Strait of Hormuz.

Key Points

  • The war cost the United States at least $33.4 billion through late June, with munitions accounting for approximately $22.3 billion; later estimates put costs near $38 billion through August 1 and project $2 billion to $3 billion in additional monthly spending.
  • The inspector general identified strategic inventory shortfalls and production bottlenecks involving solid rocket motors, explosives, propellants and skilled labor, with some advanced missiles and air-defense interceptors potentially requiring about three years to replenish.
  • U.S. forces suffered significant equipment losses, including destroyed F-15 fighters and MQ-9 Reaper drones, damaged F-35 and KC-135 aircraft, and other aircraft and personnel casualties.
  • Iranian strikes damaged hundreds of structures at U.S. bases across the Middle East and caused an estimated $184 million in diplomatic-facility damage, while repairs and some infrastructure costs were excluded from headline war estimates.
  • The assessments conflict with Trump administration assurances about unlimited ammunition and raise broader concerns about U.S. military readiness, especially in a potential confrontation with China; China is separately engaging Iran diplomatically and urging a negotiated settlement.

US Military Faces Ammunition Shortages Amid Ongoing Iran War | Africanews

The article reports that the United States military is experiencing shortages of ammunition and advanced weapons as a result of its ongoing war with Iran. A report from the Department of Defence’s inspector general estimates that the conflict cost $33.4 billion, equivalent to €29 billion, between February 28 and June 30. Nearly $20 billion of that spending went toward munitions. According to the report, the scale of weapons used during the war created “strategic inventory shortfalls” and revealed production and supply-chain bottlenecks in the US defence industry. These problems could limit the military’s ability to rapidly replace missiles, interceptors and other advanced systems. Experts cited in the article estimate that restoring stocks of advanced missiles and defensive interceptors to pre-war levels could take approximately three years. The report’s conclusions contrast with President Donald Trump’s public dismissal of concerns about military supplies. Trump maintained that US ammunition stocks are “virtually unlimited,” despite the inspector general’s assessment and the experts’ projections regarding replenishment timelines. The report also records substantial physical damage caused by Iranian strikes on US military bases across the Middle East. Hundreds of buildings and other structures were reportedly damaged or destroyed. However, the costs of repairing that damage were not included in the $33.4 billion estimate, meaning the overall financial burden of the conflict could be significantly higher. Overall, the article emphasizes the war’s effects on US military readiness, weapons inventories, industrial capacity and infrastructure, while highlighting a disagreement between official political assurances and assessments from military oversight officials and defence experts.

Iran war has led to US munitions shortfalls, Pentagon inspector confirms - BBC News

A report by the US defence department’s inspector general confirms that the war with Iran has caused strategic munitions shortfalls and bottlenecks in the American defence-industrial supply chain. The finding contradicts President Donald Trump’s repeated claims that US weapons stocks are “virtually unlimited” and that reports of shortages are false. The White House has rejected the assessment, maintaining that the military has more than enough ammunition and other munitions to meet the president’s objectives. According to the inspector general, the US spent more than $22bn on munitions between February and June, producing inventory shortfalls. The report does not reveal the precise number of weapons remaining, but it identifies industrial-base bottlenecks affecting resupply and says the Pentagon is working to speed procurement and production. US forces have used large quantities of long-range strike weapons and air-defence interceptors during the conflict, including Patriot and Terminal High Altitude Area Defense systems. A separate Center for Strategic and International Studies estimate suggested that stocks of some interceptors had fallen by more than half. The report also estimates $3.7bn in equipment losses and $7.4bn in other expenditures. Total US war costs from 28 February to 30 June were assessed at $33.4bn, while a Congressional Budget Office estimate placed the figure higher, at $38bn, after accounting for replacement munitions, destroyed equipment, flying hours and fuel. Reported losses include four F-15E fighter jets, an F-35 fighter and 30 MQ-9 drones. The article notes that the conflict, initially expected by Trump to end within weeks, may continue until after the November midterm elections. Public support is weak: a Reuters/Ipsos poll found that only 23% of Americans believed the US was in a stronger position with Iran than before the hostilities.

Several U.S. military bases, diplomatic buildings have been damaged in Iran war: inspector general report | CBC News

A Pentagon inspector general report provides the first comprehensive official assessment of the damage and costs resulting from the U.S. war with Iran, known as Operation Epic Fury. The report estimates that the operation cost $33.4 billion US through June 29, although Secretary of War Pete Hegseth later told Congress that the cost had reached $37.5 billion. It also acknowledges strategic shortfalls in advanced weapons and bottlenecks in the industrial base that could take about three years to resolve. The Pentagon has denied that it lacks sufficient munitions, and President Donald Trump has insisted that the United States is producing weapons at unprecedented levels. Iranian strikes damaged or destroyed hundreds of buildings and structures at U.S. military installations in Kuwait, Bahrain, Qatar, the United Arab Emirates, Saudi Arabia, Iraq, Oman and Jordan. The U.S. naval base in Bahrain, a key regional logistics hub, was targeted by drones and ballistic missiles, forcing Central Command to reroute supplies through more distant facilities such as Diego Garcia. U.S. diplomatic facilities in Kuwait, Saudi Arabia, the UAE and Iraq also sustained damage, with repairs estimated at $184 million. Construction projects in Israel, Egypt and Oman were delayed. The conflict generated additional costs for evacuations and emergency operations. The State Department spent $113 million on conflict-related activities, including nearly $80 million for contingency plans. About 9,000 U.S. citizens were evacuated from the Middle East and Europe, costing more than $11 million by late June. The report also details significant losses of military equipment. Up to 30 MQ-9 Reaper drones, each worth approximately $30 million, were destroyed. Seven KC-135 refuelling aircraft were damaged or destroyed, while another crashed in Iraq, killing six service members. Eleven additional service members were killed in action, and a helicopter pilot died in a non-hostile crash. Meanwhile, the United States authorized more than $44 billion in military sales to regional partners, particularly Saudi Arabia.

Iran war could cost $2 billion per month, Congressional Budget Office estimates - CBS News

A Congressional Budget Office (CBO) report estimates that the war with Iran has cost the United States approximately $38 billion between Feb. 28 and Aug. 1, excluding repairs to damaged U.S. bases. If the conflict continues at a relatively low intensity, it could cost an additional $2 billion to $3 billion per month, with expenses potentially increasing during periods of repeated tit-for-tat strikes. The CBO estimated that the conflict cost about $3 billion in July. Replacing expended munitions accounts for most of the costs. Through Aug. 1, the CBO estimates that replenishing land-attack cruise missiles, missile-defense interceptors and other munitions will cost $21.7 billion. The United States has reportedly used between one-half and two-thirds of its inventory of certain interceptors—including Patriot, THAAD and Navy Standard Missile 3 and 6 systems—since June 2025. The report warned that reduced interceptor stocks could create serious problems in a future conflict with an adversary such as China, particularly in a confrontation involving Taiwan. The CBO also estimated $1.9 billion in replacement costs for lost equipment, including a THAAD radar destroyed by Iran. That figure could rise to $3.3 billion if the Pentagon seeks newer replacement aircraft. Rising energy prices could push inflation 0.5% above previous projections during the first quarter of 2027. The findings follow a Pentagon inspector general report that identified strategic inventory shortfalls and bottlenecks in the defense-industrial base. Although President Trump and Admiral Brad Cooper have minimized concerns about depleted weapons inventories, the CBO said the Defense Department did not respond to its requests for information. The report was requested by Democratic Rep. Brendan Boyle, who criticized the war’s human and financial costs. Congress is also considering billions of dollars in additional war funding, though a Republican-backed budget measure remains stalled in the Senate.

Pentagon inspector general says $22.3B spent on Iran war munitions has caused "strategic inventory shortfalls" - CBS News

A Pentagon inspector general report says the United States is experiencing strategic ammunition shortages after spending an estimated $22.3 billion on munitions during Operation Epic Fury, the U.S. military campaign against Iran. The operation cost approximately $33.4 billion between February 28 and June 30, according to the mandatory report submitted to Congress. The report warns that the scale of munitions use has exposed bottlenecks in the defense-industrial base and made replenishing strategic inventories more difficult. The report also details military losses, including four destroyed F-15 fighter jets, one damaged F-35, seven damaged KC-135 tanker aircraft and as many as 30 destroyed MQ-9 Reaper drones. The findings conflict with repeated assurances from President Trump that the United States has virtually unlimited ammunition and is producing munitions at unprecedented levels. Mark Cancian of the Center for Strategic and International Studies said the U.S. likely has enough weapons to continue fighting Iran, but warned that sustaining a prolonged conflict or preparing for a war with China would be much more difficult. Although senior Pentagon officials previously denied that the military faced ammunition shortages, Defense Secretary Pete Hegseth has urged manufacturers to expand production. Lockheed Martin is producing 750 Patriot air-defense missiles annually, with each missile costing roughly $4 million, but the company’s missile division describes the production effort as “controlled chaos.” The report also identifies substantial non-military costs. The State Department spent $79.2 million on evacuations and other Iran-conflict contingencies. Repairs to U.S. diplomatic facilities damaged by Iranian strikes in several Middle Eastern countries are estimated at $184 million. Iranian attacks also damaged hundreds of buildings and structures at U.S. bases across the region, though the total repair cost and responsibility for paying it remain uncertain. The report follows earlier, lower estimates of the war’s cost and highlights the growing financial and logistical consequences of the conflict.

Iran Foreign Minister Abbas Araghchi to visit China

Iranian Foreign Minister Abbas Araghchi is scheduled to visit China on September 16 for talks with Chinese Foreign Minister Wang Yi, according to Beijing’s Ministry of Foreign Affairs. The meeting comes as China, which maintains close diplomatic ties with Iran and has economic interests affected by the conflict, continues to call for a ceasefire, a negotiated settlement respecting Iran’s sovereignty, and the reopening of the Strait of Hormuz. The visit follows President Donald Trump’s dismissal of Wall Street Journal reports alleging that China supplied Iran with satellite imagery of a U.S. base in Jordan. The reported intelligence was said to have helped an Iranian attack that killed three U.S. troops in July. Trump is also expected to meet Chinese President Xi Jinping in the United States on September 24, although Beijing has not confirmed the meeting. Separately, a U.S. Department of Defense inspector general report estimated that the Iran war had cost $33.4 billion through June 29. Iranian attacks reportedly damaged or destroyed hundreds of buildings and structures at U.S. bases across the Middle East and caused $184 million in damage to U.S. diplomatic facilities in Iraq, Kuwait, Saudi Arabia, and the United Arab Emirates. The report also identified significant military equipment losses and ammunition-supply problems. U.S. munitions expenditures created strategic inventory shortfalls and exposed bottlenecks in the industrial base’s ability to resupply weapons. An F-35A was damaged by enemy fire for the first time, while four F-15E fighter jets and an A-10 aircraft were destroyed. Seven KC-135 refueling aircraft, seven helicopters, and more than 30 drones were also damaged, destroyed, or lost. The article notes the costs of several aircraft types, including $92 million for an F-35A and $31.1 million for an F-15E based on the Air Force’s cited figures.

Many buildings, aircraft destroyed or damaged in Iran war: U.S. report

A U.S. Department of Defense Lead Inspector General report to Congress says the Iran war cost the United States an estimated $33.4 billion through June 29, 2026. The report covers the conflict through the end of June and details extensive damage caused by Iranian strikes against U.S. military and diplomatic facilities across the Middle East. Iranian attacks damaged or destroyed hundreds of buildings and other structures at U.S. bases, along with dozens of American aircraft. The strikes also caused an estimated $184 million in physical damage to U.S. diplomatic facilities in Iraq, Kuwait, Saudi Arabia, and the United Arab Emirates. The report identified significant losses among U.S. military aircraft. An F-35A, a fifth-generation fighter, sustained battle damage for the first time in the aircraft’s history. Four F-15E fighter jets and an A-10 ground-attack aircraft were destroyed. Seven KC-135 aerial-refueling aircraft were damaged or destroyed, while seven helicopters and more than 30 drones were lost. The report cited the F-35A’s $92 million unit cost and the F-15E’s 1998 cost of $31.1 million. Beyond the immediate physical damage and financial costs, the conflict placed pressure on U.S. weapons inventories. The expenditure of munitions reportedly created “strategic inventory shortfalls” and exposed bottlenecks in the industrial base responsible for replenishing supplies. These findings suggest that the war affected not only current military assets but also the United States’ capacity to sustain prolonged operations. The report’s findings contrasted with President Donald Trump’s assertion that the United States was producing more advanced weapons than at any previous point in its history. Overall, the article presents an accounting of wartime costs, equipment losses, infrastructure damage, and logistical challenges revealed by the conflict.

Iran war exposes US munitions shortfall, industrial bottlenecks, Pentagon report says - France 24

A Pentagon inspector general report warns that the United States is facing significant shortages of key munitions after six months of war with Iran, exposing weaknesses in the country’s defense-industrial base. The report, described as the first mandatory assessment of its kind submitted to Congress, estimates that Operation Epic Fury cost $33.4 billion between February 28 and June 30. Of that total, $22.3 billion was spent on munitions that had been used in combat. According to the report, this expenditure created “strategic inventory shortfalls” and revealed industrial bottlenecks that could delay efforts to replenish American weapons stocks. The report also details damage and losses to US military equipment, including the destruction of four F-15 fighter jets and as many as 30 MQ-9 Reaper drones. One F-35 and seven KC-135 tanker aircraft were reportedly damaged. The findings contradict President Donald Trump’s repeated assurances that US ammunition supplies are “virtually unlimited.” Trump reiterated on Truth Social that the United States is producing more advanced weapons than ever before. The article notes that CNN had previously reported shortages of long-range guided missiles and air-defense interceptors, including the near-exhaustion of 80 percent of the military’s THAAD interceptor stock. During the first day of the conflict, the United States reportedly struck more than 1,000 targets, although it has not conducted attacks on the same scale in subsequent months. Iranian attacks also damaged or destroyed hundreds of buildings and structures at US bases across Kuwait, Bahrain, Qatar, the United Arab Emirates, Saudi Arabia, Iraq, Oman, and Jordan. Those repair costs were excluded from the Pentagon’s estimate because it remains unclear which facilities will be rebuilt and who will pay for the work.

Iran war effort hampered by munitions shortfalls, production 'bottlenecks,' Pentagon watchdog finds

A report from the War Department’s Office of Inspector General says the US war with Iran has exposed serious weaknesses in the defense industrial base and created shortages of key munitions. The report identifies production of solid rocket motors, access to high-grade explosives and propellants, and the recruitment of skilled manufacturing workers as the principal bottlenecks affecting Operation Epic Fury, which began on February 28. The findings conflict with repeated assurances from President Trump and War Secretary Pete Hegseth that the United States has sufficient weapons for the conflict. Trump has claimed that defense factories are operating around the clock and expanding production of systems including Patriot, THAAD, Tomahawk and Standard Missile weapons. Experts cited in the article estimate that replenishing advanced missiles and defensive interceptors to prewar levels could take approximately three years. The congressionally mandated report estimates that the war cost $33.4 billion during its first four months, excluding infrastructure repairs. Iranian attacks damaged US bases and diplomatic facilities across the Middle East, including in Kuwait, Bahrain, Qatar, the United Arab Emirates, Saudi Arabia, Iraq, Oman and Jordan. Damage to diplomatic facilities alone was estimated at $184 million. The strike on Naval Support Activity Bahrain forced US Central Command to use more distant alternative supply hubs, including Diego Garcia, lengthening logistics cycles to between 14 and 18 days. The report also describes substantial losses of US aircraft and drones, including as many as 30 MQ-9 Reapers and seven KC-135 refueling aircraft. Eleven service members were listed as killed in action, while seven others died in non-hostile incidents. Separately, the State Department reported $113 million in conflict-related costs, including more than $11 million for evacuating roughly 9,000 Americans from the region and Europe.

Price of Epic Fury: Iran war’s toll on US bases, weapons and more | South China Morning Post

A US government watchdog has released its first official assessment of the consequences of the Iran war, known as Operation Epic Fury. The report provides the most comprehensive public accounting so far of the conflict’s impact on the United States, including damage to American aircraft, military bases and diplomatic facilities across the Middle East, as well as the costs in military personnel, taxpayer funds and physical infrastructure. The assessment was prepared by the Pentagon inspector general, drawing also on information from inspectors general for the State Department and the US Agency for International Development. Although much of the report’s information had previously been disclosed during the preceding six months, its publication offers a consolidated government account of the war’s effects. The report’s release was first reported by NBC News. A major finding concerns the depletion of US stocks of advanced weapons. The inspector general said the war had produced “strategic inventory shortfalls” and exposed bottlenecks in the American industrial base that could impede the rapid manufacture and resupply of munitions. This highlights not only the immediate expense of the conflict but also potential longer-term challenges for US military readiness and weapons production. The article does not provide detailed figures for the number of casualties, the dollar value of the damage or the quantity of weapons used. Instead, it focuses on the significance of the inspector general’s findings: the war has imposed substantial costs on US forces and facilities while revealing weaknesses in the country’s ability to replenish sophisticated ammunition. The report represents the first formal public overview of those costs and vulnerabilities.

US military says Iran war has led to munitions shortfall | The Straits Times

A US Defence Department inspector-general report says the war in Iran has created a significant ammunition shortfall and exposed weaknesses in the American defence-industrial base. The report, submitted to Congress on Sept 14, estimates that Operation Epic Fury cost US$33.4 billion between Feb 28 and June 30. Munitions accounted for US$22.3 billion of that total, and the inspector-general said the spending had produced “strategic inventory shortfalls” and bottlenecks in resupplying weapons. The conflict also caused substantial losses and damage to US military equipment. Four F-15 fighter jets were destroyed, one F-35 was damaged, seven KC-135 tanker aircraft were damaged and as many as 30 MQ-9 Reaper drones were destroyed. The United States reportedly faced shortages of long-range guided missiles and air-defence interceptors, with CNN reporting that the military had nearly exhausted 80 per cent of its THAAD interceptor inventory. These constraints have affected the US strategy in the conflict. The report contrasts with President Donald Trump’s repeated assurances that the United States has virtually unlimited ammunition and is producing advanced weapons at an unprecedented rate. US forces initially struck more than 1,000 targets during the first 24 hours of the war, but have not conducted attacks on that scale in recent months. Iranian strikes also damaged or destroyed hundreds of buildings and structures at US bases across Kuwait, Bahrain, Qatar, the United Arab Emirates, Saudi Arabia, Iraq, Oman and Jordan. However, the report excluded repair costs because it remains uncertain whether all damaged bases will be rebuilt and which party will pay for the work. Overall, the report presents the war as a costly operation that has strained US weapons stocks, military assets and production capacity.
