The first kill by an F-15 was scored by Israeli Air Force ace Moshe Melnik in 1979. During Israeli raids against Palestinian factions in Lebanon in 1979–1981, F-15As reportedly downed 13 Syrian MiG-21s and two Syrian MiG-25s. Israeli F-15As and Bs participated as escorts in Operation Opera, an air strike on an Iraqi nuclear reactor. In the 1982 Lebanon War, Israeli F-15s were credited with 41 Syrian aircraft destroyed (23 MiG-21s and 17 MiG-23s, and one Aérospatiale SA.342L Gazelle helicopter). During Operation Mole Cricket 19, Israeli F-15s and F-16s together shot down 82 Syrian fighter aircraft (MiG-21s, MiG-23s, and MiG-23Ms) with no losses.
