Israel Deploys 'Star Wars' Missile Killer System
Such high-altitude shoot-downs are meant to safely destroy incoming nuclear, biological, or chemical missiles. Israel has frequently voiced concern about a ballistic missile threat posed by its arch-foe, Iran.
The United States has its own system for intercepting ballistic missiles in space, Aegis.
Arrow serves as the top tier of an integrated Israeli shield built up to withstand various potential missile or rocket salvoes. The bottom tier is the already-deployed short-range Iron Dome interceptor, which was used extensively with high success rates in a 2014 Gaza war against Hamas militants.
Another Israeli system called David's Sling is being developed to shoot down mid-range, lower-altitude missiles, such as those in the arsenal of Iranian-backed Hezbollah, a Lebanese group which last fought a war with Israel in 2006.
