As an experiment, Aerosud, a South African aero-engineering concern, equipped a Mirage F1 with a Klimov RD-33 engine, the same engine used in the MiG-29. This development was dubbed the "SuperMirage" F1, and held the distinction of being the first Western aircraft to perform a display at the MAKS airshow in Moscow.
In 2004 up to 21 F1AZs were reported in storage at AFB Hoedspruit, awaiting a possible buyer. In April 2006, it was reported that Gabon had purchased the surviving Mirage F1AZs and spares for about ZAR 40 million. On 17 August 2006, French news agency Agence France-Presse (AFP) reported that two upgraded ex-South African F1AZs had taken part in a fly-past over Libreville earlier that day in celebration of Gabon's independence day. The refurbishment and upgrade of the aircraft was carried out by Aerosud. Aerosud Group managing director Dr. Paul Potgieter confirmed his company's involvement, but declined to give numbers or cite figures. It was also reported at that time that Gabon had only bought 3 Mirage F1 from South Africa, and it was unclear whether the third aircraft was another F1AZ or a two-seat F1CZ.
