Hi,

I found this article from Aerosud, the South African company involved in the RD33 Super Mirage F1 project. It looks it was only one plane modified with the RD33 and then no follow up since that.

SYSTEM ENGINEERING MANAGEMENT

The lead role that Aerosud played in the re-engining of the Mirage F1 and Mirage III-derived Cheetah aircraft with a variant of the Russian Klimov RD33 engine used in the Mig 29 Fighter has brought the company substantial International recognition. Aerosud was assigned overall system responsibility for this program, and also conducted the detailed design of all airframe and airborne systems modifications, whilst its Russian partners were responsible for the redesign of the engine and the design of a new accessory gearbox. Both the F1 and Cheetah prototypes were successfully flight tested and performed exceptionally well. The ” Super Mirage F1″ technology demonstrater was displayed and successfully demonstrated at the MAKS airshow in Moscow during August 2001.
