Why in the news?
Israel successfully intercepted an Iranian missile outside Earth’s atmosphere using an Exoatmospheric kill vehicle.
Israeli Air-Defence Systems
Israel’s multi-layered air defence system, including Iron Dome, The Arrow, and David’s Sling, was activated in anticipation of the attack.
- IRON DOME: The short-range Iron Dome air defence system was built to intercept the kind of rockets fired by the Hamas in Gaza. Developed by state-owned Rafael Advanced Defense Systems with US backing, it became operational in 2011. Each truck-towed unit fires radar-guided missiles to blow up short-range threats like rockets, mortars and drones in mid-air.
- ARROW: The long-range Arrow-2 and Arrow-3 system, developed by Israel with an Iranian missile threat in mind, is designed to intercept ballistic missiles outside the earth’s atmosphere, using a detachable warhead that collides with the target. It operates at an altitude that allows for the safe dispersal of any non-conventional warheads.
- DAVID’S SLING: This mid-range system is designed to shoot down ballistic missiles fired from 100 km to 200 km away. Developed and manufactured jointly by Israel’s state-owned Rafael Advanced Defense Systems and the U.S. Raytheon Co, David’s Sling is also designed to intercept aircraft, drones and cruise missiles.

What are Exoatmospheric Missiles?
- Exoatmospheric missiles, or anti-ballistic missiles (ABMs), operate beyond Earth’s atmosphere to intercept incoming ballistic missiles.
- They employ advanced sensors and guidance systems to detect, track, and destroy targets in space.
- Kinetic kill vehicles, like the Exoatmospheric Kill Vehicle (EKV), rely on high-speed collisions to neutralize threats.
- It travels at hypersonic speed.
Working Mechanism of Exoatmospheric Missiles:
- The EKV uses a solid rocket booster to propel itself into space.
- Advanced sensors and onboard computers identify and track incoming threats.
- Precise maneuvering allows the missile to navigate towards the target.
- Impact from a high-speed collision eliminates the threat without traditional warheads, enhancing speed and accuracy.
