A report prepared for Congress by the Lead Inspector General in the US has been released, detailing the casualties and damage resulting from Iranian attacks and acknowledging the depletion of ammunition stockpiles during the conflict.
The report was prepared under the supervision of the US Department of Defense Inspector General, who was designated as the ‘Lead Inspector General’ on May 12, 2026. It covers the situation up to June 30, 2026.
According to the report, the consumption of ammunition during the US conflict with Iran—designated as ‘Operation Epic Fury’—led to a reduction in US military stockpiles, while obstacles hindering the production capacity required for replenishment also came to light.
The report notes that the US faces several persistent challenges in the arms manufacturing industry, including the production of solid rocket motors, the availability of advanced explosives and propellants, and a shortage of skilled labor.
Citing the Department of Defense office responsible for overseeing arms procurement and logistics, the report indicates that significant time will be required to increase production capacity.
According to the Lead Inspector General’s report on Operation Epic Fury submitted to Congress, 11 US soldiers were killed in combat operations between February 28 and June 30, 2026, while seven others lost their lives in non-combat incidents. During the same period, 417 US soldiers were wounded. The report cites a statement from the U.S. Central Command (CENTCOM) noting that Iranian attacks damaged or destroyed hundreds of buildings and installations at U.S. military bases across Kuwait, Bahrain, Qatar, the United Arab Emirates, Saudi Arabia, Iraq, Oman, and Jordan.
According to the report, dozens of U.S. aircraft were destroyed or damaged during the operation. The document states that four F-15E fighter jets were lost—three to friendly fire and one to enemy fire.
An F-35A fighter jet was damaged by enemy fire while flying over Iran, while an A-10 aircraft was destroyed after sustaining damage upon returning from a combat search-and-rescue mission.
Similarly, seven KC-135 aerial refueling tankers were destroyed or damaged; one was lost in a collision within Iraqi airspace, another was damaged, and five were hit during Iranian attacks in Saudi Arabia.
The report indicates that an E-3 aerial surveillance aircraft was damaged by Iranian attacks in Saudi Arabia, while an HH-60W helicopter was affected during combat search-and-rescue operations.
According to the document, an MQ-4C unmanned aircraft crashed, and four AH-6 helicopters sustained such severe damage that U.S. forces destroyed them themselves.
The report also states that an AH-64 helicopter was shot down over the Strait of Hormuz, and an MH-60 helicopter crashed into the Arabian Sea. In addition, the destruction of 30 MQ-9 type surveillance and attack drones has been reported.
