The US Army has reportedly used up much of its stockpile of highly accurate long-range missiles during its five-month conflict with Iran, according to multiple sources familiar with the data. The missiles primarily involved are the Army Tactical Missile Systems (ATACMS) and Precision Strike Missiles (PrSM), both surface-to-surface weapons.

Two sources stated that the US has used “virtually all” of these weapons, a level of depletion not previously reported. A fourth source noted that Central Command, which oversees US forces in the Middle East, has nearly exhausted its pre-war land-based missile supplies but has managed to reload from other US military reserves globally.

These long-range munitions, costing over US$1 million each, are critical for conducting precise strikes from safe distances. ATACMS have also been significant in the war in Ukraine, enabling Ukrainian forces to target inside Russia. The newer PrSM is designed to replace ATACMS with a longer range, though its stockpiles were initially low; the US military has placed large orders for 2027.

President Donald Trump initiated the Iran war jointly with Israel in February, anticipating a short conflict. The ongoing depletion of missile stockpiles has sparked internal government discussions about the sustainability of continued strikes without compromising readiness for other crises.

Chief Pentagon spokesperson Sean Parnell responded to inquiries by affirming, “America’s military is the most powerful in the world and has everything it needs to execute at the time and place of the President’s choosing.” Meanwhile, defense companies are reportedly producing munitions at unprecedented rates and expanding their manufacturing capabilities.
