First nuclear weapon test in South Africa

South Africa reached an understanding with the United States after signing a 50-year collaboration under the U.S.-sanctioned programme, Atoms for Peace. The treaty concluded the South African acquisition of a single nuclear research reactor and an accompanying supply of highly enriched uranium (HEU) fuel, located in Pelindaba. South Africa was able to mine uranium ore domestically and used aerodynamic nozzle enrichment techniques to produce weapons-grade material.
