Context: The Iron Dome aerial defence system just intercepted a Hamas Unmanned Aerial Vehicle (UAV) that crossed from Gaza into Israel.

What is Iron Dome?

  • Iron Dome is a multi-mission system capable of intercepting rockets, artillery, mortars and Precision Guided Munitions like very short range air defence (V-SHORAD) systems as well as aircraft, helicopters and Unmanned Aerial Vehicles (UAV) over short ranges of up to 70 km.
  • It is an all-weather system and can engage multiple targets simultaneously and can be deployed over land and sea.
  • Iron Dome is jointly manufactured by Rafael Advanced Systems and has been in service with Israeli Air Force since 2011.

How does it work?

  • An Iron Dome battery consists of a battle management control unit, a detection and tracking radar and a firing unit of three vertical launchers, with 20 interceptor missiles each.
  • The interceptor missile uses a proximity fuse to detonate the target warhead in the air.
  • One of the system’s important advantages is its ability to identify the anticipated point of impact of the threatening rocket, to calculate whether it will fall in a built-up area or not, and to decide on this basis whether or not to engage it.
  • This prevents unnecessary interception of rockets that will fall in open areas and thus not cause damage.
  • The I-DOME is the mobile variant with all components on a single truck and C-DOME is the naval version for deployment on ships.

What are the limitations of the system?

  • The system has a ‘saturation point’.
  • It is capable of engaging a certain (unpublished) number of targets at the same time, and no more.

One of the possible limitations is the system’s inability to cope with very short range threats as estimates put the Iron Dome’s minimum interception range at 5-7 kilometres.
