Military analysts and US officials have warned that the United States will need years to replenish weapons stockpiles depleted during the recent conflict with Iran, according to multiple reports. Estimates range from one to six years, depending on the type of munition and the source of the assessment.

The reports, carried by TASS, cite Italian military analyst Gianluca Di Feo writing in La Repubblica, the Washington-based Center for Strategic and International Studies (CSIS), and comments from a senior US general. The assessments paint a picture of significant consumption of precision-guided munitions and raise questions about the US military's readiness for other potential conflicts.

Coverage Comparison

Coverage of the weapons depletion varies in focus and sourcing. Three TASS articles addressed the issue from different angles: one emphasized the strategic implications for the US rivalry with China, another highlighted consequences for the war in Ukraine, and a third focused on the CSIS report's analysis of specific missile types and timelines.

All three articles agree that US operations against Iran consumed a substantial portion of key weapons systems and that replenishment will take years. However, the estimates vary: Di Feo suggests five to six years, while CSIS analysts project one to four years for specific systems. A US general, Lieutenant General Heath Collins, director of the Missile Defense Agency, acknowledged that replenishment would take "years" without specifying a timeline, as reported by TASS.

Key Claims

  • Weapons consumption: Reports indicate the US expended over a third of its Tomahawk cruise missiles and half of its THAAD and Patriot interceptor arsenal during the conflict, according to US House of Representatives member Pat Ryan, as cited by TASS. The CSIS report lists extensive use of Tomahawk and JASSM missiles, Precision Strike Missiles (PrSM), SM-6 and SM-3 interceptors, as well as THAAD and Patriot missiles.
  • Replenishment timelines: Estimates for rebuilding stockpiles to prewar levels range from one to four years for the seven munitions analyzed by CSIS, to five to six years according to analyst Gianluca Di Feo. Lieutenant General Heath Collins said it would take "years" without elaborating.
  • Numbers of casualties: According to the Iranian side, 3,375 Iranians died as a result of US and Israeli attacks during the 40 days of war, as reported by TASS.
  • Ceasefire and talks: US President Donald Trump announced a two-week mutual ceasefire with Iran on April 7, which was later extended unilaterally. Iran and the US held talks in Islamabad on April 11, but both sides reported failure to reach a long-term agreement due to disagreements. The Iranian delegation was led by parliament speaker Mohammad Bagher Ghalibaf, and US Vice President JD Vance headed the US delegation, according to CSIS via TASS.

Perspectives

Analysts and officials offer differing views on the implications of the weapons depletion. Di Feo argues that the depletion "weakens the US in the face of its strategic rival, China," and notes that efforts to bring down the Islamic Republic have failed. CSIS experts emphasize that stockpiles were already deemed insufficient for a potential Western Pacific conflict before the Iran war, and the shortfall is now "even more acute."

On the Ukraine front, Russian State Duma member Mikhail Sheremet suggested that the US arms shortage "will significantly impact the course of military operations and hasten the inevitable defeat of the Kiev junta," although this framing reflects a Russian government perspective. He also noted that US manufacturers provide approximately half of Western arms transfers to Ukraine, a claim that could not be independently verified.

CSIS analysts also warn that the heavy use of Patriot, THAAD, and PrSM missiles in the Iran operation will undermine Washington's ability to supply weapons to Ukraine and other allies and partners, a concern echoed by Lieutenant General Collins in his acknowledgment of the replenishment challenge.
