found this from a South African site..
number of different reports were published each claiming to be as accurate as the previous report. Some of the reports suggested that the existing Cheetah Es were re fitted with Atar 9K50 engines from the retired F1CZ aircraft, some claimed the Cheetah “R” was the latest type under Project 855 or Project Bark and even quoted the total cost of this project, while others claimed the Cheetah “R” was actually the new Cheetah C under development. There were even reports that South Africa had developed a twin Atar 9K50 fighter aircraft and a model of this type at an aerospace exhibition fuelled more speculation that “Project Cava” existed. Although the model was essentially a single engine aircraft. But the sole Cheetah “R” fuelled the majority of reports as many concluded the SAAF was in need of reconnaissance aircraft as very few aircraft remained in the SAAF’s inventory that could be used for this role. The SAAF simply capitalised on wrong reports in the media to protect its current black project which was well underway.
