Story summary
Summary of Iran-US War Developments
Between February 28 and June 30, the United States and Israel launched "Operation Epic Fury," a military campaign against Iran that cost an estimated $33.4 billion, with nearly $22.3 billion spent on munitions alone. The Pentagon's Inspector General report to Congress revealed significant challenges, including strategic inventory shortfalls and industrial bottlenecks in resupplying munitions. Iranian retaliatory strikes damaged or destroyed hundreds of buildings at U.S. bases across the Middle East, including up to 30 MQ-9 Reaper drones, four F-15 fighter jets, one F-35 jet, and seven KC-135 tanker aircraft.
President Donald Trump has dismissed concerns about munitions shortages, stating that the U.S. possesses "virtually unlimited" supplies of ammunition. However, Pentagon officials acknowledge significant expenditures in both personnel deployment and weaponry use, which have led to strategic inventory shortfalls and revealed industrial base bottlenecks for munitions resupply. The report highlights the need for streamlining procurement processes and stockpiling critical materials to prepare for potential future contingencies.
The cost of repairing damaged facilities and replacing lost or damaged aircraft is not included in the current estimate, indicating that the total financial impact could be even higher. Despite these challenges, U.S. officials maintain readiness for any potential contingency while considering diplomatic avenues to end hostilities with Iran. (Total cost: $33.4 billion; munitions expenditure: $22.3 billion)
