It was during the Vietnam War that the U.S. Air Force, to counteract the Soviet surface-to-air missiles that had inflicted heavy casualties on it, invested in reconnaissance drones nicknamed “Lightning Bugs,” produced by Ryan Aeronautical. An American official explained that “these RPVs [remotely piloted vehicles] could help prevent aircrews from becoming casualties or prisoners… With RPVs, survival is not the driving factor.”
Once the war was over, those machines were scrapped. By the late 1970s, the development of military drones had been practically abandoned in the United States. However, it continued elsewhere. Israel, which had inherited a few of these machines, recognized their potential tactical advantages.
In 1973, the Israel Defense Forces (IDF), facing off against Egypt, ran up against the tactical problem of surface-to-air missiles. After losing around 30 planes in the first hours of the Yom Kippur War, Israeli aviation changed its tactics. They decided to send out a wave of drones in order to mislead enemy defenses: “After the Egyptians fired their initial salvo at the drones, the manned strikes were able to attack while the Egyptians were reloading.” This ruse enabled Israel to assume mastery of the skies. In 1982, similar tactics were employed against the Syrians in the Bekaa Valley. Having first deployed their fleet of Mastiff and Scout drones, the Israelis then sent out decoy planes that were picked up by enemy radar. The Syrians activated their surface-to-air missiles, to no effect whatsoever. The drones, which had been observing the scene from the sky, easily detected the positions of the antiaircraft batteries and relayed them to the Israeli fighter planes, which then proceeded to annihilate them.
