Why America's Missile Supplies Could Run Out in Days During a Pacific War

The United States might exhaust its supply of advanced missiles in as few as three days if drawn into a conflict with China over Taiwan, according to new analysis that reveals a troubling gap between today's missile readiness and Cold War stockpiles. Some of the most sophisticated interceptor missiles could potentially be depleted within 24 hours of the fighting's opening.

This assessment highlights how American missile and warhead supplies have shrunk to about one-tenth of their peak levels during the Cold War, leaving what analysts now call an "American missile crisis"—a crisis born from thirty years of reduced manufacturing and vulnerable supply chains.

Manufacturing Infrastructure Left Fragile

America's ability to make missiles quickly has weakened since the Cold War ended. Where multiple competing manufacturers once existed, the industry has consolidated, creating dangerous single points of failure.

After the Cold War, two companies dominated the production of ammonium perchlorate, the chemical oxidizer that powers solid rocket fuel: Kerr-McGee Chemical Corporation and Pacific Engineering and Production Company (PEPCON) in Nevada. Then, on May 4, 1988, the PEPCON plant in Henderson, Nevada exploded. The blast destroyed 9 million pounds of ammonium perchlorate inventory, killed two workers, injured 372 others, and wiped out roughly half of America's domestic supply capacity in a single event.

This brittleness persists across the entire defense supply chain. Many critical missile components are made by only one or two suppliers, and these suppliers cannot quickly ramp up production if demand surges during a crisis.

The Pacific Threat Is Fast-Moving

Military planners are increasingly focused on the Western Pacific, where China has deployed roughly 500 DF-26 missiles—intermediate-range ballistic missiles designed to strike targets across the region with reasonable accuracy, according to a 2023 Pentagon assessment. These missiles can reach US military bases spread across the Pacific, forcing American forces to operate from further away.

The real problem is speed. In a Cold War scenario, a conflict might drag on for months or years, giving factories time to produce more missiles. But a Pacific conflict could unfold in days. The most advanced interceptor missiles—the ones designed to stop incoming ballistic missiles as they descend toward their targets—would face sudden, massive demand. The factories that build these systems are already running near capacity and cannot simply switch into overdrive.

Having covered the defense industry through several major shifts in military technology, I observed comparable warnings about production delays during the 1990s when military bases were closed and consolidated. The difference now is the pace at which modern missiles would be consumed—far faster than anything the Cold War prepared us for.

A Snapshot of Cold War Abundance

During the Cuban Missile Crisis in 1962, the United States possessed enormous stockpiles of missiles backed by a massive industrial base that could manufacture more relatively quickly. CIA Director John McCone stated at the time that America's goal was to remove Soviet missiles from Cuba and eliminate the Castro government—a goal he saw as achievable because American military superiority seemed overwhelming.

The crisis itself began when Fidel Castro accepted Soviet missiles into Cuba. Castro later said he hadn't actually thought Cuba needed these missiles for its own defense; he accepted them primarily to deepen Cuba's ties with the Soviet Union. The US, meanwhile, had stationed Intermediate Range Ballistic Missiles in Turkey as part of its broader NATO strategy.

After the Cuban Missile Crisis, both superpowers began negotiating arms control agreements that steadily reduced their missile inventories. What seemed like sensible restraint during the Cold War's final decades now looks potentially risky in an era when China and other competitors operate by different strategic rules.

What the Pentagon Is Doing Now

The Department of Defense has spent at least $84 billion on missile defense systems over the past ten years, with plans to spend another $3.3 billion in the next five years. Recent moves show where military planners are worried: the Pentagon deployed a THAAD battery (a mobile air defense system) to Israel, ordered additional ballistic missile defense destroyers to the Middle East, and is adding fighter squadrons and refueling aircraft to the region.

The Pentagon is also working on an ambitious plan called "Golden Dome"—a network of linked sensors, radars, and interceptors designed to protect the continental US from missiles launched anywhere in the world. These efforts reflect both the Pentagon's awareness of missile threats and its broader concern about whether it has enough advanced weapons to fight a major war.

The US and Israel have conducted joint exercises specifically designed to counter Iranian missile attacks. In Bahrain, an American-operated Patriot air defense battery was involved in a pre-dawn explosion that injured multiple people, illustrating the real-world operational risks of deploying these systems.

Where This Leads

The shortage of missiles points to a larger question about how America builds weapons in an age of great power competition. Russian President Vladimir Putin has drawn a parallel between current US missile defenses in Europe and the Cuban Missile Crisis itself, arguing that American defensive deployments risk triggering the same kind of escalatory spiral that nearly sparked nuclear war in 1962.

Looking at the strategic picture, missile shortages force difficult choices between defending current operations and keeping reserves for a possible Pacific conflict. Every Patriot missile launched in the Middle East today reduces the supply available for Taiwan or Japan. Every THAAD battery sent abroad is one fewer system protecting the US homeland.

There is also a security risk embedded in this fragility. Adversaries could disrupt production by damaging key facilities or exploiting vulnerabilities in the supply chain. A single industrial accident or targeted attack could cripple American missile manufacturing for months.

The difference from the Cold War era is stark. American military planners once assumed they would have overwhelming numbers and industrial capacity to replace losses. Now they must carefully manage a finite inventory of expensive, difficult-to-manufacture weapons. The shift from quantity-based strategies to precision-based warfare has created a new kind of vulnerability.

These constraints will eventually reshape both how the military operates and how the Pentagon invests in manufacturing. Policymakers will need to balance the demands of today's conflicts against the need to build production capacity sufficient for a longer war against a peer competitor.
