U.S. Missile Production Strains Under Iran Conflict
By Drooid · · How we work
The Emerging Shortage
The United States’ war against Iran has exposed a shortfall in high-end munitions. Each Patriot air-defense missile costs roughly $4 million, and Lockheed Martin’s Camden, Arkansas plant turns out about 750 units annually—far below the estimated 1,500 Patriots fired in the Iran campaign. Mark Cancian of the Center for Strategic and International Studies (CSIS) estimates that munitions expended against Iran total around $25 billion. By April 8, the United States Joint Force had struck more than 13,000 targets, further depleting stockpiles.
Context: From Ukraine to Iran
Cancian argues the “wake-up call” came from the 2022 war in Ukraine, which revealed insufficient inventories and surge capacity. The subsequent Iranian conflict, now in its seventh month, has highlighted the gap between peacetime stockpiles and the demands of a protracted war, especially when contrasted with the looming challenge of a potential conflict with China.
Production Bottlenecks and New Efforts
Lockheed Martin plans to boost Patriot output from 750 to 2,000 per year by adding shifts and increasing automation. Tim Cahill notes the assembly line currently takes six weeks per missile, while the 4,000 component parts require about two years to manufacture. The supply chain relies on 500-1,000 suppliers; a single missing part can halt production. Rocket motors, supplied by L3Harris, involve a curing process that can take days to weeks, adding further delay.
Start-up CoAspire, based in Manassas, Virginia, is pursuing a low-cost cruise missile (Rapidly Adaptable Affordable Cruise Missile (RAACM)) with roughly 200 parts, many off-the-shelf, and the Pentagon intends to purchase 10,000 units. This approach contrasts with Lockheed’s $59 billion high-performance Patriot contract.
Official Statements & Responses
The Pentagon has dismissed reports of shortages, stating “Claims of U.S. munition shortages are false.” Defense Secretary Pete Hegseth has urged industry to operate at a “wartime footing,” emphasizing speed, scale, and efficiency. CSIS’s Cancian cautions that replenishing pre-war stockpiles could take one to five years, with additional years needed to reach levels suitable for a China-focused strategy.
