According to a new analysis, U.S. military contractors will require at least three years to replenish stockpiles of three critical weapons systems that were heavily utilized during the Iran war. The report, released Wednesday by the Center for Strategic and International Studies (CSIS), raises concerns about America's firepower capabilities in any future conflict with China.
Key Weapons Systems Depleted
The weapons systems in question include Tomahawk cruise missiles, which target deep inside enemy territory, as well as Patriot and THAAD interceptors that defend against incoming missiles and drones. The analysis notes that while the United States had sufficient munitions for any plausible scenario in the Iran war, the depleted inventories have created a window of vulnerability for a potential Western Pacific conflict.
China Threat and Strategic Concerns
China has stated its goal of ensuring its military can take Taiwan by force if necessary by 2027, though experts view this as more aspirational than a hard deadline. Chinese President Xi Jinping recently warned that mishandling relations with Taiwan could lead to a clash or open conflict between the U.S. and China.
Historic Defense Budget
The analysis factors in the Trump administration's historic defense budget proposal of $1.5 trillion for 2027, which accelerates spending on high-end munitions that began under the Biden administration. While there is bipartisan agreement in Congress to boost inventories, the report emphasizes that the problem is not money but time. Expanding production capacity and building these complex systems takes years.
Production Timelines
CSIS estimates that it could take until late 2030 to fully replenish the prewar inventory of Tomahawk missiles, of which over 1,000 were fired at Iran. Fewer than 200 Tomahawks are produced annually due to past small orders, but manufacturer Raytheon aims to ramp up capacity to more than 1,000 per year. For THAAD interceptors, replacing up to 290 units could take until the end of 2029, while replenishing over 1,000 Patriot interceptors should be completed by mid-2029.
Political Reactions
President Trump and Defense Secretary Pete Hegseth have insisted the U.S. is capable of fighting any war and have pushed defense contractors to speed up production. Chief Pentagon spokesman Sean Parnell stated that the military has everything it needs to execute operations. However, some military experts and Democrats criticize the Iran war, which Trump launched without congressional approval. Republicans argue that the problem stems from sending Patriot systems to Ukraine after Russia's invasion in 2022.
Mark Cancian, a retired Marine colonel and CSIS senior adviser who co-authored the study, noted that the Ukraine war demonstrated the need for deep inventories of advanced weapons. He credited the Biden administration for starting conversations with the defense industry and ramping up production, while acknowledging that the Trump administration significantly increased funding.
