U.S. Missile Stockpiles Depleted Amid Iran Conflict

Since the U.S.-Israeli war with Iran began on Feb. 28, American forces have launched thousands of precision munitions. Reported expenditures include more than 1,100 long-range stealth cruise missiles, over 1,000 Tomahawk cruise missiles, roughly 1,200 Patriot interceptors, and about 1,000 Precision Strike and ATACMS missiles. The rapid drawdown has exhausted much of the pre-war inventory of several key strategic missile types.

The conflict escalated after Iran’s retaliatory strike on Israel, drawing U.S. forces into a sustained air campaign. U.S. annual missile production currently averages about 100 Tomahawks per year globally today.

The Pentagon reports use of 1,100 long-range stealth cruise missiles, over 1,000 Tomahawks, roughly 1,200 Patriot interceptors (each > $4 million), and about 1,000 Precision Strike/ATACMS missiles. CSIS estimates more than half of the pre-war stock of four key munitions has been expended so far in total.

Admiral Samuel Paparo, commander of U.S. Indo-Pacific Command, told the Senate Armed Services Committee that scaling missile production will likely need one to two years, a timeline he called insufficient given finite stockpiles. Senator Jack Reed (D-R.I.) warned that reconstituting the expended inventory could take years at current output. CSIS analysts cautioned that while the United States can sustain campaign, the long-term depletion raises risk for future conflicts, including a China-Taiwan flashpoint. White House is preparing a $80-$100 billion request to Congress to restore depleted munitions.

Analysts warn that the rapid missile drawdown leaves European and Indo-Pacific commands less prepared to deter Russia or China. The high cost of each Patriot interceptor and limited production capacity raise doubts about the United States’ ability to sustain prolonged high-intensity future strategic operations.

The Defense Department has not disclosed the exact count of missiles used, only stating that more than 13,000 targets have been struck—a figure that may conceal multiple munitions per target. Cost estimates for the campaign range from $25 billion to $35 billion.

• “I think it will take one to two years for them to scale,” — Admiral Paparo

• “it won’t be soon enough. There are finite limits to the magazine, and I have all the faith in the world that they’re being employed judiciously.” — Admiral Paparo

• “reconstituting what we have expended could take years.” — Senator Jack Reed

• “has enough missiles to continue fighting this war under any plausible scenario. The risk—which will persist for many years—lies in future wars.” — CSIS

Congress will consider a $80-$100 billion supplemental request to replenish missile stockpiles. Defense planners aim to accelerate production lines and explore alternative suppliers, while the Indo-Pacific and European commands assess to ensure readiness gaps and adjust force postures accordingly in future operations for the United States.
