Love to know what happened to the South African Cheetahs after being taken off line. They were decedents of the Kfir if my memory is correct. J79’s? why not a GE-404? or P & W F-100?
The Cheetahs were sold to Ecuador. I don’t think a F-100 would fit; An F-404 would be feasible, but I don’t think U.S. companies would be keen on supporting it given it would eat into potential U.S. sales.
