Having sustained aircraft losses during the Six-Day War of 1967 and the War of Attrition fought during the late 1960s, the Israeli Air Force (IAF) sought to procure an improved variant of the highly successful Dassault Mirage III fighter aircraft. While a partnership to produce such an aircraft, the Mirage 5, was formed between French manufacturer Dassault Aviation and Israeli aerospace company Israel Aircraft Industries (IAI), during January 1969, in response to the 1968 Israeli raid on Lebanon, the French government announced that it would be imposing an arms embargo on Israel. In response to the embargo, Israel decided to proceed with the venture, but to domestically manufacture the airframes instead.
