Iran is firing fewer missiles at Israel each day, making it easier for Israeli air-defense systems to intercept them, according to Israeli officials and air-defense experts.

The Arrow system intercepts long-range missiles at higher altitudes; the David’s Sling system intercepts them at lower altitudes; while the Iron Dome takes out shorter-range rockets, usually fired from Gaza, or the fragments of missiles already intercepted by other defense systems.

Iran is boasting that it has hypersonic missiles and says it already has begun firing the cutting-edge weapons at Israel.
