How does Iron Dome protect Israel from rocket attacks?

Question

Accepted Answer

Iron Dome Provides Multi-Layered Defence Against Rocket Threats

Israel's Iron Dome air defence system serves as a critical shield against rocket attacks, protecting both military and civilian areas. Since its deployment in 2011, the system has successfully intercepted thousands of rockets, most recently engaging over 200 drones and missiles launched by Iran. Its operational capability extends to countering threats originating from Gaza and Lebanon, forming an integral part of Israel's broader missile defence strategy.
System Composition and Operational Mechanism

The Iron Dome is engineered to intercept short-range rockets travelling up to 70 kilometres. Each operational battery comprises three core components: a sophisticated radar detection system to identify incoming projectiles, a computer unit that calculates the rocket's trajectory, and a launcher. Interceptors are deployed when the trajectory analysis indicates a high probability of the rocket striking a populated or strategically important location. This system works in conjunction with other defence layers, such as the Arrow system for ballistic missiles and David's Sling for medium-range threats.
Development and International Collaboration

Initially developed independently by Israel following the 2006 Lebanon War, the Iron Dome project later saw collaboration with the United States. This partnership has been significant, with the US contributing crucial defence expertise and substantial financial backing, amounting to billions of dollars, across various administrations. This support underscores the strategic importance of the system within the US-Israeli alliance.
Performance and Cost of Interception

The Iron Dome system boasts an impressive interception rate of approximately 90%, according to its developer, Rafael. This effectiveness comes at a considerable cost, with each interceptor missile estimated to cost between US$40,000 and US$50,000 to produce. A complete Iron Dome system, including radar, computer, and multiple launchers, is estimated to cost around US$100 million. Israel currently operates ten such systems, with the US Army also having acquired two batteries to bolster its own short-range defence capabilities.
