As stated, due to world pressure, the RSA took apart their Nukes. I think we had 4 or so. We still have several nuclear research facilities and a
large nuclear power plant. I think the greatest benifit to RSA was the natural materials like uranium that we have plenty of.
Our Nukes were never meant to be used against a "communist" foe but were rather a political deterent that, if ever another nation attacked SA then
we would be forced to use them unless the world intervened. I dont believe we had developed any long range missiles to carry them and there were
intended to be drpped by plane.
Popular thought also says that the apartheid government didnt want to hand over nukes to the new ANC lead government.
It might sound crazy, but one of my high school science teachers, Mrs Lamb, was an ex nuclear scientist who worked on the bombs. She lost her job in
the early 90's when they cancelled the program. She never told us any more than that!
