Iron Dome is a mobile all-weather air defense system developed by Rafael Advanced Defense Systems and Israel Aerospace Industries. The system is designed to intercept and destroy short-range rockets and artillery shells fired from distances of 4 kilometres (2.5 mi) to 70 kilometres (43 mi) away and whose trajectory would take them to an Israeli populated area. Israel hopes to increase the range of Iron Dome's interceptions, from the current maximum of 70 kilometres (43 mi) to 250 kilometres (160 mi) and make it more versatile so that it could intercept rockets coming from two directions simultaneously.
