IAI HARPY
At the end of the 1980s, a new type of weapon appeared based on the existing anti-radiation missiles but with the exceptional characteristic of being able to remain in flight over a determined area waiting to locate a target to launch against it. These new missiles/drones were called “loitering munition”, and the Israeli IAI Harpy was the first to be operational in the early 90s, since then many models have been developed and it has become a lethal weapon with great flexibility, within the reach of any army thanks to its low cost.
