As of early March 2026, the assessment of missile production for both the
and
highlights a significant "asymmetry of inventory," where Iran produces offensive missiles at a higher monthly rate than the U.S. can produce the high-end interceptors used to stop them.
Iranian Missile Production (Offensive)
Iran possesses the largest and most diverse missile arsenal in the Middle East, with many systems capable of reaching Israel (range of 1,000+ km).
- Monthly Production Rate: Current estimates from the U.S. Secretary of State and Israeli Intelligence place Iran's ballistic missile production at over 100 units per month. Some Israeli assessments suggest a goal of reaching 300 precision missiles per month by 2027-2028.
- Total Inventory: Before recent strikes, the IDF assessed Iran's stockpile at approximately 2,500 to 3,000 ballistic missiles.
- Wartime Status: While production remains high, U.S. and Israeli airstrikes (Operation Epic Fury) have reportedly destroyed roughly 50% of Iran's operational launcher fleet as of March 2, 2026.

U.S. Interceptor Production (Defensive)
The U.S. produces high-end "interceptors" (PAC-3, SM-3, THAAD) to counter Iranian missiles. These are significantly more complex and slower to build than the offensive missiles they target.
- Monthly Production Rate: U.S. Secretary of State Marco Rubio noted a stark gap, stating that the U.S. can only build six or seven interceptors per month compared to Iran's 100+ offensive missiles.
- Annual Scaling Goals: To address this, Lockheed Martin and the Pentagon recently signed agreements to "turbo-charge" production, aiming to move from roughly 600 to 2,000 Patriot (PAC-3) missiles and from 96 to 400 THAAD missiles annually over the next few years.

The "Inventory Arithmetic" Problem
Experts warn of a depletion risk because the rate of fire during major salvos exceeds the rate of replenishment.
- Expenditure Ratio: In a single major conflict in June 2025, Iran fired over 500 missiles in a few days—nearly 70 times the current monthly U.S. production rate for the interceptors needed to stop them.
- Stockpile Depth: While President Trump claims a "virtually unlimited supply" of medium-grade munitions, CNN and the WSJ report that "super high-end" interceptors like the SM-3 and Tomahawk are under severe strain.
