What is Israel’s Iron Dome?

Israel’s Iron Dome is a mobile all-weather air defense system developed by Rafael Advanced Defense Systems and Israel Aerospace Industries. First deployed in 2011, it is designed to intercept and destroy short-range rockets and artillery shells fired from distances of 4 kilometers to 70 kilometers. The system has proven to be a critical component in protecting Israeli civilians from threats originating from neighboring territories.

The Iron Dome system includes several key components:

  • Detection and Tracking Radar: Identifies and tracks incoming projectiles.
  • Battle Management and Weapon Control (BMC): Analyzes threats and coordinates interception strategies.
  • Missile Firing Unit: Launches Tamir interceptor missiles to neutralize threats in mid-air.

 Materials and Components Used in Israel’s Iron Dome

The construction of the Iron Dome involves a combination of advanced materials and sophisticated technology. The primary components include the radar system, control center, and interceptor missiles, each made from a range of specialized materials:
