US runs out of nearly all of its long-range missiles leaving Trump short of options in Iran

US Missile Stockpiles Reduced Following Operations in Iran, Sources Report

The US Army has expended nearly all of its stockpile of Army Tactical Missile Systems (ATACMS) and Precision Strike Missiles (PrSM) during five months of operations against Iran, according to three people familiar with internal data. These surface-to-surface weapons, each costing more than $1 million, enable strikes from beyond the range of many air defenses.

Two of the sources stated that supplies of these specific munitions are nearly exhausted. The weapons have supported strikes on targets inside Iran, as noted in a March report by the Center for Strategic and International Studies. The PrSM is the newer system intended to replace the shorter-range ATACMS.

A fourth person familiar with the matter said Central Command has drawn down its pre-war allocation of land-based missiles but has drawn replacements from stocks held in other regions. All sources spoke on condition of anonymity.

President Donald Trump, who began joint operations with Israel in February, stated that the United States possesses “far more munitions than anyone in the world” and “far more than we need.” The White House added that defense contractors are producing munitions at record rates while expanding facilities.

Lockheed Martin, the manufacturer of the ATACMS, PrSM, and THAAD systems, and Raytheon, which produces Tomahawk missiles and Patriot interceptors, did not respond to requests for comment on current inventory levels.

Analysts have noted that production of certain munitions, including artillery shells and missiles, has increased, though output may remain below levels required for an extended conflict. The Army has indicated it is phasing out ATACMS production in favor of the PrSM.

Two sources reported that military leaders have advised the president on dwindling stocks of defensive interceptors, including Patriots and THAAD missiles. Last week, multiple outlets reported that Trump declined to authorize a further large-scale offensive in part due to these supply concerns. A US official stated the decision instead reflected pressure from Gulf states.

No authorization for use of military force or declaration of war has been requested from Congress.

A CSIS report published last week estimated that roughly 65 percent of Patriot interceptors and at least 38 percent of THAAD interceptors had been used between February and July. Two sources confirmed these figures align with internal data. One source added that the United States has used slightly less than half of its global Tomahawk inventory since operations began. Reuters did not independently verify the Tomahawk figure.

Raytheon has reached a tentative multi-year agreement with the Pentagon to increase Tomahawk output along with other munitions.

The ATACMS has previously been supplied to Ukraine for strikes inside Russia. Analysts have stated that long-range precision weapons would be relevant in any future conflict involving adversaries with advanced air defenses.

Trump administration officials have emphasized that production capacity is expanding. The three sources expressed concern that continued high consumption could affect readiness for other contingencies. The White House statement did not address specific remaining quantities of ATACMS or PrSM.

The operations have continued without a request for congressional authorization. Central Command has supplemented theater stocks from global reserves, according to the fourth source. Production contracts for the PrSM have been increased for delivery in 2027, consistent with the Army’s transition plan away from the ATACMS.

No independent public audit of exact remaining quantities has been released. The figures cited by sources match those referenced in internal administration discussions over the past week.
