US Missile Stockpiles Shrink After Months of Iran Conflict

NEW YORK/WASHINGTON — August 4, 2026

The United States has used a significant portion of its long-range precision missile stockpiles during its five-month conflict with Iran, prompting concerns among some officials about the country's military readiness if another major conflict breaks out.

Officials familiar with internal military data said the U.S. Army has used nearly all of its available Army Tactical Missile Systems (ATACMS) and Precision Strike Missiles (PrSM) during the campaign. The weapons are designed to strike targets accurately from long distances, allowing forces to attack without exposing pilots to heavily defended airspace.

The reported depletion of these missiles has not previously been made public. Officials said the remaining inventory has become the subject of discussions within the Trump administration as military planners assess how long operations against Iran can continue without affecting readiness for other potential conflicts.

The sources, who spoke on condition of anonymity because they were not authorized to discuss the matter publicly, did not disclose how many missiles remain in U.S. stockpiles. They said some officials are concerned that reduced inventories could weaken the country's ability to respond quickly to future military crises involving adversaries such as China or Russia.

One official said the U.S. Central Command has been able to replenish some supplies by moving weapons from stockpiles in other regions, helping sustain operations despite the heavy demand.

President Donald Trump dismissed concerns over the reported decline in missile inventories. In a statement, he said the United States still possesses more military munitions than any other country and that American defense manufacturers are increasing production while expanding their manufacturing facilities.

The Pentagon also rejected suggestions that military readiness has been compromised. Chief Pentagon spokesperson Sean Parnell said U.S. forces continue to maintain the capabilities needed to carry out missions around the world while protecting national interests.

Military analysts agree that production of several key weapons has increased in recent years. However, they also warn that advanced precision-guided missiles require time to manufacture, making it difficult to quickly rebuild inventories after prolonged military operations.

Officials said one reason for the heavy use of long-range missiles was to reduce the need for riskier attacks by crewed aircraft against targets inside Iran. These weapons allow the military to strike from safer distances, particularly against heavily defended targets.

The newer Precision Strike Missile is expected to gradually replace the older ATACMS as the Army modernizes its missile forces. While production of the newer system is increasing, analysts note that existing stockpiles remain relatively limited because the weapon only recently entered service.

Concerns also extend to defensive missile systems. Officials said military leaders have warned for weeks that inventories of Patriot missile interceptors, which are used to defend against ballistic missile attacks, have fallen during the conflict.

A recent study estimated that approximately 65% of Patriot interceptors had been used between February and July, while the number of THAAD missile interceptors had fallen by at least 38% during the same period. Two officials familiar with internal government figures said those estimates generally match official data.

Another source said the United States has also used slightly less than half of its global inventory of Tomahawk cruise missiles since the conflict began. That figure has not been independently confirmed.

Defense manufacturers are working to increase missile production. Companies producing Tomahawk missiles and other advanced weapons have reached agreements with the Pentagon to expand manufacturing as the United States seeks to rebuild stockpiles after months of military operations.

The debate over missile supplies comes as the conflict with Iran continues and policymakers weigh ongoing military requirements against the need to maintain sufficient weapons for future security challenges elsewhere in the world.
