Why Tackling Iranian Drones Is A Job For Israel’S Helicopter Gunships

An Israeli AH-64 Apache engages and shoots down an Iranian suicide drone in footage released by the. More IDF IDFDramatic videos are emerging of Israeli AH-64 Apache helicopters shooting down Iranian attack drones. The advanced U.S.-supplied helicopters are pursuing and destroying propeller-driven drones with bursts from their 30mm cannon. But the encounters illustrate an interesting point: the drones are getting past Israel’s world-class interceptor missiles and have to be stopped at close range. In a long war, helicopters vs drones could become a crucial factor in protecting civilians.Iron Dome Protection Comes At A CostIsrael has a layered air defence missile system, comprising the long-range Arrow, the medium-range David’s Sling and THAAD and the short range Iron Dome. Between them, these are capable of tackling everything from ballistic missiles launched from Iran to home-made Qassem rockets fired from Gaza.Israel's Iron Dome air defence system shooting down incoming Hezbollah rockets in August 2024 AFP via Getty ImagesThis system is supported by a complex network of radar and other sensors and has proven extremely effective at swatting down missile attacks mid-air
