The United States is facing growing pressure on its military stockpiles as operations against Iran continue, with key air defense systems and long-range precision weapons being consumed faster than they can be replenished, according to The Washington Post.

Citing a U.S. official, the newspaper reported that the military “does not have enough to safely sustain operations,” reflecting concerns over the pace at which critical munitions are being used.

The report also cited intelligence assessments indicating that Iran still possesses the majority of the missile arsenal it had before the conflict, despite months of military exchanges.

The widening gap between U.S. weapons consumption and Iran’s remaining missile inventory has raised concerns inside Washington about the sustainability of a prolonged campaign and the strain on American military resources.

The conflict has added to existing pressure on U.S. defense stockpiles, which have already been stretched by support for Ukraine and broader security commitments in the Indo-Pacific and Middle East. The Pentagon has been working to expand production of advanced missiles and air defense interceptors, but replenishing inventories is expected to take time.

The report highlights the growing logistical and financial challenges facing the U.S. as the conflict enters a prolonged phase, with billions of dollars’ worth of precision-guided munitions and interceptor missiles already expended.
