US Military Aid to Israel: A $3.3 Billion Investment in Defense Against Iran

Strategic Insights

— 1 min read

As part of the US-Israel memorandum of understanding, the US invests $3.3 billion annually in military aid to Israel, with a significant portion of this aid being utilized during the recent operation against Iran. The US assistance to Israel in this operation reached an exceptionally high amount, with the US launching about 15%-20% of all THAAD system interceptors in the world against Iranian ballistic missiles, costing over $800 million. The THAAD system, developed by Lockheed Martin, is designed to intercept ballistic missiles in the terminal phase, using an advanced radar from Raytheon.

Key Takeaways:

  • The US invested over $800 million in THAAD interceptors during the operation against Iran, at a cost of about $12.7 million per interceptor missile.
  • The THAAD system, with a 6-8 launcher capacity and eight interceptors per launcher, demonstrated a high level of effectiveness, intercepting 60-80 Iranian ballistic missiles with an 85%-90% success rate.
  • The deployment of THAAD in Israel presents a challenge to the Trump administration due to economic and operational concerns, including the high cost of each interceptor missile and the potential need for additional air defense systems to counter emerging threats.
  • The THAAD system has a unique capability to track up to seven targets at once and has maneuvering capabilities similar to Israel's David's Sling system.
  • The THAAD system has previously proven itself in operational level interceptions, including the January 17, 2022, interception of a Houthi rebel missile launched against the UAE.
  • The US military aid to Israel, as part of the memorandum of understanding, totals $3.3 billion annually, with a significant portion being utilized during the operation against Iran.
