Why it matters
The report highlights potential strategic vulnerabilities and the high economic and material costs of the U.S. military engagement in West Asia.
The U.S. Department of Defence's inspector general revealed Monday (September 14, 2026) 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 February 28 and June 30, Operation Epic Fury (OEF) had an estimated cost of $33.4 billion, with $22.3 billion of that spent on expended munitions alone.
The report noted, "The munitions expenditure on OEF has resulted in strategic inventory shortfalls and revealed industrial base bottlenecks for munitions resupply."
It also lists losses to the American fleet, including four F-15s destroyed, one F-35 damaged, seven KC-135 tanker aircraft damaged and up to 30 MQ-9 Reaper drones destroyed.
