Israel has a multilayered air-defense network that includes systems capable of intercepting a variety of threats including long-range missiles, cruise missiles, drones and short-range rockets. However, in a massive attack involving multiple drones and missiles, the likelihood of a strike making it through is higher.
Israel's defense system with assistance from the U.S. and Britain is credited with preventing serious damage or casualties.
This system developed with the U.S. is designed to intercept long-range missiles, including the types of ballistic missiles Iran said it launched on Saturday. The Arrow, which operates outside the atmosphere, has been used in the current war to intercept long-range missiles launched by Houthi militants in Yemen.
Also developed with the U.S., the David’s Sling is meant to intercept medium-range missiles, such as those possessed by Hezbollah in Lebanon.
