The Pentagon’s inspector general has warned that the U.S. military is facing strategic ammunition shortfalls after the costly war in Iran, according to a mandatory report submitted to Congress.
Operation Epic Fury cost an estimated $33.4 billion between February 28 and June 30, with $22.3 billion spent on munitions. The report said the heavy weapons use exposed bottlenecks in America’s defense production capacity.
President Donald Trump has dismissed concerns about depleted stocks, saying the U.S. is producing advanced weapons at record levels. The Pentagon has also denied claims of shortages.
However, defense officials are pressing manufacturers to accelerate production. Mark Cancian of the Center for Strategic and International Studies warned that current supplies may be sufficient for Iran but could become a serious challenge during a prolonged conflict with China.
