Why the US Military Could Run Out of Missiles in Just Three Days

The United States could exhaust its supply of advanced missiles in as little as three days if conflict broke out between China and Taiwan, according to a recent analysis. Some specialized defensive missiles designed to intercept incoming aircraft could run out within the first 24 hours.

This shortage stems from a fundamental problem: the US maintains far fewer missiles today than it did during the Cold War, when America stockpiled weapons in enormous quantities. At its peak in the 1960s, the US had roughly ten times more missile firepower than it does now. Experts call this gap the "American missile crisis."

How Cold War Success Led to Today's Weakness

After the Cold War ended in the early 1990s, the US sharply reduced missile production. This made sense at the time — there was no longer a direct superpower rival to fight. But it created a new problem: the factories and supply chains that built missiles never fully recovered.

Consider rocket fuel. Two American companies made almost all the solid rocket fuel oxidizer used in US missiles: Kerr-McGee and PEPCON. That concentration meant there was no backup plan. On May 4, 1988, the PEPCON plant in Henderson, Nevada exploded. The blast involved 9 million pounds of this fuel, killed two people, and injured hundreds. Overnight, America lost about half its missile fuel production capacity.

This fragility never went away. Today, many missile components come from a single supplier or a handful of factories. If one breaks down or gets attacked, the US has no quick alternative. Ramping up production takes months or years, not weeks.

The Modern Threat

China has deployed roughly 500 intermediate-range ballistic missiles — the DF-26 — throughout the Western Pacific, according to a 2023 Pentagon report. These weapons can hit US military bases across the region, forcing American forces to operate from farther away and making defense harder.

The problem is speed. Modern conflicts could consume advanced missiles far faster than anyone imagined during the Cold War. Defensive missiles — the ones designed to stop incoming attacks — face particular pressure. They are complex to manufacture and built slowly, even in peacetime.

I have covered defense manufacturing through several major shifts in technology, and we have seen warnings about production bottlenecks before. But what is different now is the pace. Modern weapons fly and get used up in days, not weeks. The old Cold War assumption — that America could build its way out of a shortage once a conflict started — no longer applies.

What the Pentagon Is Doing

The Department of Defense has spent at least $84 billion on missile defense over the past ten years. It plans to spend another $3.3 billion over the next five years.

Recent moves show the urgency of this concern. The Pentagon is positioning more air defense systems in the Middle East and has ordered additional destroyers designed to defend against missiles. The US and Israel recently ran joint exercises focused on countering threats together.

The Real Strategic Problem

The shortage of missiles forces difficult choices. Every missile fired at a target in the Middle East today is one that will not be available if a larger conflict erupts in the Pacific. Every defensive system sent to one region weakens another.

An adversary can exploit this vulnerability in multiple ways. A targeted attack on a key factory, a supply chain breakdown, or even an accident could shut down missile production for months. The US also must balance how many missiles to keep in reserve against how many it uses now.

The shift from the Cold War era is stark. Then, American planners assumed they would always have more weapons than any rival and could produce more quickly if needed. Now, the US must carefully allocate its limited missiles and hope production can keep pace. That change will likely reshape both military strategy and how the Pentagon manages its defense contractors in the years ahead.
