Are the Raptor or Torgos operational with the SAAF? Is it maybe part of a unknown (secret?) strategic strike arsenal along with our mini nukes that we don't know of?

Maybe we have these things but don't know about it. Hey, they kept the nukes pretty concealed all those years.

Unfortunately, or perhaps fortunately, we have not been able to generate the material to build any nukes for many years. Not even secretly as our facilities are open to international inspection. Building a mini-nuke is probably way beyond our technological capability at present. However I do have a PDF I wrote a decade ago about how to build a nuke in one's garage - it does presuppose that one has obtained the fissile material elsewhere. There is no way one could generate either the U-235 or P-239 in the garage. Both require hideously expensive and large complicated facilities which emit enough radioactive daughter gasses to alert busybodies like Uncle Sam and Ivan and the international nuclear regulatory organizations as to what one is up to.
Our nuclear program produced the simplest of A-bombs. Not much better than the one that was dropped on Hiroshima 6th August 1945. Using prodigious amounts of cash and at the rate of about one a year. And even then the fissile material was only just good enough - way below the grade used in the Hiroshima bomb - to make a bang. And like almost all post 1945 nukes harmed the builder nation more than anything else.
Perhaps I should write another companion PDF on how to refine uranium and generate and purify plutonium? Not unless you have access to oodles and oodles of cash.
