A recent report issued by the Center for Strategic and International Studies (CSIS), dated April 2026, has revealed a critical and alarming state of the US’ major munitions stockpiles in the aftermath of the conflict with Iran, indicating the existence of “lethal gaps” in American defense capabilities.
Follow-ups – Al-Khabar Al-Yemeni:
The data shows a rapid and unprecedented depletion of several vital missile systems. For example, between 1,060 and 1,430 “Patriot” missiles have been consumed, representing a significant portion of the original stockpile of 2,330 missiles.
Additionally, more than 1,000 “JASSM” missiles have been used out of 4,400 and more than 850 “Tomahawk” missiles. More critically, most of the “PrSM” small missile stockpile (40-70 out of 90) has been consumed, as well as the majority of the “THAAD” stockpile (190-290 out of 360).
The enormous financial cost and lengthy replenishment timeline exacerbate the crisis. For instance, the unit cost of the “SM-3” interceptor missile is $28.7 million, which is the most expensive, and new orders take 64 months to deliver, which is more than five years. The “THAAD” missile also costs up to $15.5 million, with a delivery time of 53 months.

The report warns that this industrial sluggishness and replenishment gap of 42 to 64 months for all systems creates “critical readiness risks,” leaving the US vulnerable for a long period due to its inability to quickly compensate for the shortage. The overall view of the crisis describes the situation as “rapid stockpile depletion” met with “industrial production sluggishness.”
