US spent $33.4 billion in four months on Iran war, arms stocks depleted
Pentagon inspectors report the United States spent about 33.4 billion dollars on its military action against Iran between February 28 and June 30, 2026, depleting key weapons stocks.
The United States has suffered heavy financial losses in the war it has waged against Iran. A Pentagon inspectors' report shows that between February 28 and June 30, 2026, the United States spent about 33.4 billion dollars on its military action against Iran. The largest share of this amount went on ammunition and weapons. Moreover, after this heavy spending, the United States' stocks of key weapons have also fallen.
According to the report, the United States used missiles, air defence systems and other ammunition on a large scale during the action against Iran. This weaponry alone accounted for 22.3 billion dollars in spending, the largest share of the total war cost. In addition, about 3.7 billion dollars in military equipment was damaged, and the remaining expenses came to about 7.4 billion dollars.
The large-scale use of weapons has seriously affected the United States' military stockpiles. The Pentagon report states clearly that stocks of some key ammunition have fallen to strategically low levels. Shortages have also emerged in the availability of rocket motors, high-grade explosives, propellant and skilled manpower. Because of this, the United States may have to spend considerable time and money going forward to restore depleted weapons stocks to their earlier levels.
The United States' military action has also caused major losses of aircraft, drones and other military equipment. Iranian attacks have also damaged infrastructure at some American military bases in the Middle East. This is why the current figure of 33.4 billion dollars cannot be treated as the final cost of the war. Repairing equipment, replenishing weapons stocks and making good the damage to military bases are expected to involve even bigger expenses going forward.
Overall, the United States has spent 33.4 billion dollars on this war against Iran in just four months. Of this, 22.3 billion dollars went on ammunition alone, and the heavy use of weapons has placed significant strain on the United States' military stockpiles.
