U.S. annual production of navy and missile defense systems has shifted into high-scale mobilization as of early 2026, driven by high expenditure rates in conflicts involving

Iran

and defense operations in

Israel

Navy Missile Production (Anti-Ship & Strike) 

The U.S. Navy relies heavily on the Standard Missile (SM) family and Tomahawk cruise missiles for both defensive interceptions and offensive strikes. 

  • SM-3 (Aegis Ballistic Missile Defense): Annual production for 2025 was approximately 71 units, with 66 projected for 2026. New framework agreements with RTX (Raytheon) aim to accelerate this further, as the U.S. fired roughly a year's worth of these interceptors during recent defenses of Israel.
  • SM-6 (Multi-mission): Current production is roughly 125 units per year. Recent deals aim to increase this to over 500 units annually.
  • Tomahawk Cruise Missile: Production was approximately 70–90 units per year as of 2025. Under a new 2026 agreement, RTX is scaling capacity to 1,000+ units annually to replenish stocks after 400 were fired in the first 72 hours of operations against Iran. Seapower MagazineSeapower Magazine +6

Missile Defense Systems (Israel & Gulf States) 

These systems are the primary shield against Iranian ballistic missiles and drones. 

  • Patriot (PAC-3 MSE): Lockheed Martin delivered 620 interceptors in 2025. A landmark January 2026 agreement with the Pentagon aims to more than triple this capacity to 2,000 units per year.
  • THAAD (Terminal High Altitude Area Defense): Historical production has been low, at roughly 50–96 units per year. In early 2026, Lockheed Martin broke ground on new facilities to quadruple output to 400 units annually.
  • Expenditure Note: During the June 2025 conflict, the U.S. fired approximately 150 THAAD interceptors, nearly 25% of the total global inventory at the time. Lockheed MartinLockheed Martin +7

As of early March 2026, the assessment of missile production for both the

U.S.

and

Iran

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. The Times of IsraelThe Times of Israel +4

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. Al JazeeraAl Jazeera +2

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. Middle East MonitorMiddle East Monitor +2
