Iron Dome can operate in all weather conditions and at any time; one launcher holds 20 intercept missiles at a given time. The system uses a radar to detect an incoming projectile. The radar tracks the projectile while also alerting the other system components — the battle management and weapons control (BMC) component and the launcher — of the incoming threat. It also estimates where incoming projectiles will hit and only focuses on those threats that will fall in the area the system is meant to protect. Rafael boasts that this strategic targeting makes the system extremely cost-effective.
Defense News reported on August 12 that the US had purchased two Iron Dome systems, although it's unclear how much the Department of Defense paid for them, or where or how they will be deployed.
While the system has been very useful for Israel against more rudimentary Hamas- and Hezbollah-launched projectiles, it would be less so against weapons like hypersonic missiles, which can maneuver midflight.
