Following peace between Egypt and Israel in 1979, the RJAF began to modernize its fleet once again. The first part of this program was the procurement of the Dassault Mirage F1 which became the RJAF's frontline fighter supported by generous aid from wealthy oil-rich Arab states. The Mirage F1 was selected over the General Dynamics F-16/79 (an F-16A powered by the GE J79 turbojet series as opposed to the Pratt & Whitney F100, which had 25% more power in afterburn) while also acquiring the Northrop F-5 to complement the Mirage F1CJ/EJ in the process.
