The United States military expended more than $5 billion worth of munitions during the first two days of the war against Iran, according to officials familiar with a Pentagon assessment provided to Congress.

The report, delivered to lawmakers on Monday, estimates the cost of the weapons used at approximately $5.6 billion. The massive expenditure is raising growing concern on Capitol Hill about how quickly the Pentagon is depleting some of its most advanced weapons systems.

Much of the spending came from the extensive use of long-range precision-guided munitions during the opening days of the conflict, weapons that are among the most sophisticated and costly in the U.S. arsenal.

At the same time, the United States and its allies are firing large numbers of air-defense interceptors to shoot down incoming Iranian ballistic missiles and drones. Iran is believed to possess a massive stockpile of both systems, increasing the pressure on defensive capabilities.

Arizona Senator Mark Kelly noted that the scale of Iranian missile and drone inventories means defensive operations are consuming large quantities of interceptors.

Kelly said senators would continue pressing military officials in closed-door briefings for detailed updates on the daily cost of the conflict and the rate at which munitions are being used.

Several congressional sources told CNN that the ongoing war will likely force the administration to request emergency supplemental funding from Congress to replenish the rapidly shrinking weapons stockpiles.

“That’s the next big fight,” one congressional aide said, referring to the expected battle in Washington over approving additional funding for weapons production.
