...reduced the numbers yes but never given them up...
The South Africans gave their nuclear weapons up in the 1990s. Nukes that could have been dropped from the Bucc, no less!
From
Wikipedia:
South Africa developed a small finite deterrence arsenal of gun-type fission weapons in the 1980s. Six were constructed and another was under construction at the time the program ended.
None of the six bombs were particularly sophisticated, being designed to be delivered from one of the aircraft types then in service with the South African Air Force, presumed to have been either the Buccaneer or Cheetah D.
However, South Africa had a relatively sophisticated intercontinental ballistic missile programme running concurrently with the nuclear programme, and was known to be working on more sophisticated nuclear weapons capable of delivery from such a platform. According to published data one of the missiles, the RSA-4, may have been capable of delivering a 700 kg nuclear warhead from its South African launch site to any point on earth.
