The United States burned through nearly half of its most advanced long-range missiles in just weeks of war with Iran, and now faces a real “window of vulnerability” if another major fight breaks out soon.

Story Snapshot

Analysts say the U.S. used at least 45 percent of its Precision Strike Missiles during the Iran war.
Key stocks of Tomahawk, Patriot, and other high-end missiles also plunged and will take years to rebuild.
Pentagon-linked experts warn of a near-term risk if a second major war erupts before inventories recover.
This missile drawdown exposes deeper problems in America’s defense industry, planning, and deterrence.

America’s missile edge took a major hit in the Iran war

U.S. forces went to war with Iran in late February and leaned hard on a small set of “exquisite” missiles for the opening air and missile campaign. The Center for Strategic and International Studies, a major Washington defense think tank, studied seven of these weapons and found that for at least four, the United States likely fired more than half of its prewar inventory.

That list includes Tomahawk cruise missiles, Joint Air-to-Surface Standoff Missiles, Precision Strike Missiles, Terminal High Altitude Area Defense interceptors, and Patriot air defense missiles.

The drawdown was not a slow bleed. In the first 39 days before the initial ceasefire, U.S. forces struck over 13,000 targets, often using these long-range precision weapons to smash Iranian missile launchers, air defenses, command sites, and nuclear-linked facilities.

Analysts estimate the United States used around 1,100 long-range stealth cruise missiles designed for a possible war with China, leaving a similar number still in the stockpile. That kind of front-loaded firepower won the opening round in Iran but chewed through years of careful missile buildup.

Precision Strike Missile stocks were hit especially hard

The Precision Strike Missile, or PrSM, is the U.S. Army’s new ground-launched long-range weapon meant to reach more than 500 kilometers and replace the older Army Tactical Missile System. It fired in combat for the first time in this war.

The problem is that PrSM was just entering service, so prewar stocks were low. CSIS estimates that only about 90 had been delivered by 2026. Of those, analysts believe between 40 and 70 were used against Iran, and one Army official even claimed the “entire inventory” was expended.

A separate CSIS-linked analysis that closely tracks Defense Department data concluded that the U.S. military had expended at least 45 percent of its Precision Strike Missiles overall.

Another estimate from the Payne Institute said U.S. forces burned through nearly 46 percent of combined Army Tactical Missile Systems and Precision Strike Missiles within the first 16 days alone. Reports from Aviation Week described a U.S. Army unit firing all of its new PrSM missiles at the start of the war, showing how quickly small stocks can disappear once combat begins.

Air and missile defense interceptors also plunged

The strike campaign did not only drain ground-attack missiles. It also hit America’s air and missile defense inventory. CSIS found that the United States may have used roughly half of its Patriot missile interceptors and more than half of its Terminal High Altitude Area Defense interceptors during the Iran war.

Defense-focused outlets repeated the same warning, saying Patriots were down by about two-thirds of the prewar stock in some assessments, creating readiness challenges for other theaters.

These interceptors are what protect forward bases, allies, and carrier groups from ballistic missiles and large drone swarms. Iran has built a large missile force with systems like the Fateh-313 and Zolfaghar, so U.S. commanders had to shoot often to keep bases alive.

That defensive success came at a price. Analysts now worry about what happens if another crisis — say in the Western Pacific — demands thousands more interceptor shots while stocks are still recovering.

Rebuilding inventories will take years, not months

Missiles like Tomahawk, Terminal High Altitude Area Defense, Patriot, Precision Strike Missile, and Joint Air-to-Surface Standoff Missile are not quick-turn “factory goods.”

CSIS’s deeper replenishment study says JASSM and PrSM will take several months to a year to replace, while systems such as Tomahawk, THAAD, Patriot, SM-3, and SM-6 will take between two and four years to return to prewar levels. The think tank warned that the window of vulnerability will last for several years, even with new production lines coming online.

U.S. officials themselves have echoed this concern. Reporting from CBS News quoted defense officials who said the American industrial base cannot produce missiles fast enough to replenish what was fired in the Iran campaign, creating mounting pressure on stockpiles.

CSIS analysts also cited Defense Secretary Pete Hegseth saying that replenishment would take “months and years” depending on the weapon system, a blunt admission that high-end munitions are a long-term project, not a quick refill.

What this means for deterrence and conservative priorities

For conservatives who care about peace through strength, these numbers raise red flags. CSIS stressed that the United States still has enough missiles to keep fighting in Iran, but warned that “the risk — which will persist for many years — lies in future wars.”

In plain terms, if America had to fight Iran again and also face a major crisis with China or Russia, it could not repeat this kind of high-end missile campaign for long without running short.

This shortage debate exposes deeper problems. Government stockpile data is classified, so the public must rely on think-tank work, budget documents, and anonymous sources. That secrecy makes it harder to hold leaders accountable for planning and production failures.

It also opens the door for defense industry voices to push their own narratives to win bigger contracts. Yet the core facts here come from multiple aligned analyses and inside sources, not fringe commentary, and they point to a real gap between America’s war plans and its missile inventory.

Pressure to fix the missile gap

Experts argue that the answer is not panic, but serious policy. They call for larger standing inventories of long-range precision missiles, faster surge capacity in factories, and more discipline about when to fire the most advanced weapons. Some analysts suggest shifting more routine strikes to cheaper systems once enemy air defenses are knocked down, saving high-end missiles for truly critical targets. That approach already began late in the Iran campaign, as U.S. forces moved from Tomahawk and PrSM to shorter-range, more plentiful munitions.

For ordinary Americans, the message is simple and important. The United States won the first round in Iran with high-tech firepower, but that win revealed how thin our missile margin really is. In a dangerous world, running that close to empty on the tools that protect troops and allies is not a luxury a serious country can afford.
