  • Israel confirmed using its David's Sling air-defense system to intercept a Hamas rocket on Friday.
  • David's Sling is the middle part of Israel's sophisticated and multi-layer air-defense network.
  • That network also includes Iron Dome for short-range threats and Arrow systems for longer ranges.

Israel on Friday was forced to activate its David's Sling medium-range air-defense system, marking the first time since it declared war on Hamas last weekend that the country has turned to aerial protection beyond the Iron Dome.
