UNMANNED AERIAL VEHICLES IN THE SERVICE OF THE : “THEY WILL SOAR ON WINGS LIKE EAGLES” By David Rodman*

The Israel Air Force (IAF) has a rich history of employing unmanned aerial vehicles in battle with excellent results, and is set to expand significantly its drone operations in the coming decades, as the increasing sophistication of these vehicles makes them suitable for a rapidly expanding set of roles. In the future, the IAF's drone force could alter Israel’s strategic landscape, reinforcing both its nuclear and conventional deterrence, as well as making it less dependent on American military assistance .

Unmanned aerial vehicles (UAVs), often designers, and so on—familiarity with the referred to colloquially as drones, can claim a Jewish state’s UAV operations, past and lineage that dates back to the dawn of air present, is not widespread. A brief review of warfare. Though quite rare in comparison to Israel’s experience with drones, as well as a the enormous numbers of manned aircraft few thoughts about the future of its UAV involved in the first and second world wars, force, then, seems entirely in order. The UAVs participated in both conflicts, especially employment of these vehicles is set to expand the latter, mainly as attack vehicles armed dramatically in the years ahead, if the fighting with high-explosive warheads.
