Is America Running Out of Weapons?
The United States remains the world’s strongest military power. However, recent conflicts have raised new questions about whether its defense industry can replace advanced weapons as quickly as modern warfare consumes them. Since February 2026, heavy military operations against Iran, continued support for Ukraine, and growing deterrence efforts in the Indo-Pacific have significantly increased demand for precision-guided missiles and interceptors.
Although US officials insist there is no immediate weapons shortage, defense experts say several critical missile inventories have declined faster than expected. They also warn that rebuilding these sophisticated systems will require years because modern missiles are far more complex to manufacture than conventional munitions. As global security commitments continue to expand, the Pentagon faces the challenge of maintaining combat readiness while restoring key stockpiles.
Iran War Accelerated the Consumption of America’s Advanced Missiles
The Iran campaign demonstrated the extraordinary pace at which high-end weapons can be used during a large-scale conflict. During Operation Epic Fury, US forces struck more than 13,000 targets across Iran and intercepted over 1,700 Iranian drones and ballistic missiles. According to the US government, the campaign cost approximately $37.5 billion, with most of the funding spent on munitions. Analysis by the Center for Strategic and International Studies (CSIS) indicates that the United States fired more than 1,000 Tomahawk cruise missiles and over 1,000 JASSM cruise missiles during the operation. The campaign also required extensive use of Patriot and THAAD interceptor missiles, reducing inventories of several critical weapons.
While President Donald Trump has said the United States still possesses more munitions than any other nation, Defense Secretary Pete Hegseth has requested an additional $87 billion to replace expended weapons and strengthen military readiness. CSIS estimates that rebuilding some of these missile inventories could take one to four years, while full recovery for certain systems may extend until 2031 under current production plans.

Global Conflicts and Supply Chain Weaknesses Are Reshaping America’s Weapons Strategy
The long-term issue extends beyond battlefield consumption and into the defense manufacturing sector. According to Mark Cancian, a senior adviser at CSIS, producing a modern missile can take one to five years because manufacturers rely on specialized facilities, skilled workers, and highly complex supply chains. The Pentagon’s Industrial Capabilities Report found that 98% of second-tier and 98% of third-tier suppliers are single-source manufacturers, leaving few alternatives if a supplier exits the market. In addition, critical materials such as Ammonium Perchlorate, Dechlorane Plus 25, and Dimeryl Diisocyanate face serious supply constraints, limiting the industry’s ability to expand production quickly.
Defense planners also remain concerned about reliance on foreign suppliers, particularly for materials previously sourced from China. At the same time, the possibility of a future crisis involving Taiwan and continued military assistance to Ukraine could further increase demand for advanced missiles. As a result, America’s long-term military advantage will depend not only on the strength of its armed forces but also on the resilience and capacity of its defense industrial base.
