A new U.S. think-tank analysis says rebuilding depleted stockpiles of several advanced weapons systems heavily used in strikes against Iran will take at least three years, raising concerns about available firepower in a future conflict in the Western Pacific. The report focuses on three systems: Tomahawk cruise missiles used for long-range strikes, and Patriot and THAAD interceptor missiles used to defend against incoming missiles and drones. While the analysis indicates the United States has enough munitions for any plausible scenario involving Iran, it warns that reduced inventories create a “window of vulnerability” for potential contingencies closer to East Asia. The report emphasizes that the main constraint is not funding but time required for production and replenishment of advanced munitions. It is also cited alongside discussion of defense planning, including mention of a proposed 2027 U.S. defense budget. The analysis is presented as part of broader debate over whether current industrial capacity and procurement timelines could meet rapid wartime demand while maintaining readiness for other strategic challenges.
