How depleted weapons stockpiles could affect the Iran conflict

March 4, 2026

The conflict between the US-Israel alliance and Iran is consuming weapons and munitions at an unsustainable pace, with over 2,000 coalition strikes already conducted and Iran launching nearly 2,000 missiles and drones combined. Intelligence indicates Iran's attack rate has dropped dramatically—down 86% for ballistic missiles and 73% for drones since the conflict's first day—suggesting depleting stockpiles or strategic conservation amid destroyed air defenses and production facilities. While the US possesses deeper conventional weapons reserves and has shifted to less expensive munitions now that it controls Iranian airspace, critical air defense systems like Patriot missiles remain in limited supply with only about 700 produced annually.

Who is affected

United States military forces and defense industrial base
Iran's defense ministry, military forces, and weapons production facilities
Israel and its military conducting joint operations
Arab allies of the US requiring air defense systems
Ukraine (competing for limited Patriot missile supplies)
US defense contractors being pressed to increase production
Civilians in Iran where strikes are targeting weapons facilities and launchers

What action is being taken

The US and Israel are conducting strikes hunting down Iran's missile and drone launchers, weapons stockpiles, and production facilities
The US Air Force is using JDAM bombs dropped above targets (having shifted from long-range Tomahawk cruise missiles)
Iran is launching ballistic missiles and drones (though at significantly reduced rates)
The US is using Patriot missiles and other air defense systems to intercept Iranian attacks
The US is drawing down on Patriot missile stockpiles

Why it matters

This conflict demonstrates that even the world's most powerful military faces resource constraints during high-intensity warfare, particularly with expensive precision-guided weapons and air defense systems produced in limited quantities. The depletion of US Patriot missile stockpiles—estimated at around 1,600 units with only 700 produced annually—creates strategic vulnerabilities, especially if the US needs these systems for a potential Pacific conflict with China. The situation also reveals the limitations of air campaigns alone, as historical examples from Gaza and Yemen show that intensive bombing campaigns struggle to completely eliminate adversaries or their hidden weapons caches, meaning sustainable production capacity may ultimately determine outcomes in prolonged conflicts.

What's next

President Trump is scheduled to meet with defense contractors later this week to press them to speed up weapons production
US Central Command plans to continue the next phase focused on hunting down Iran's missile and drone launchers, weapons stockpiles, and destroying production factories
