Oerlikon-Bührle enabled licensed manufacture of gun barrels and ammunition in South Africa from 1964 and later of complete guns. In the 1980s, the group provided technical and organisational support for further development of 35 mm air defence under the Sleeve and Skavot projects. On 13 November 2002, a US civil lawsuit by Ed Fagan in Florida against Unaxis, formerly Oerlikon-Bührle, announced for that day, became known. It concerned Oerlikon-Contraves arms and licence sales during apartheid. Fagan sought to hold Unaxis responsible for transactions before the arms division was sold to Rheinmetall in 1999. The subsequent outcome of this specific announced lawsuit is not documented. In 1974, Oerlikon-Bührle confirmed to Swiss authorities a contract for 36 DCA-type 35 mm anti-aircraft guns with ammunition for South Africa. The guns were to be manufactured at Oerlikon Italiana in Milan and some ammunition in Singapore. The delivery schedule ran until 1979. The case concerns production abroad and is distinct from the Swiss Bührle smuggling cases of the 1960s. In the US class action known as the South African Apartheid Litigation, Khulumani plaintiffs also cited arms deliveries by the Oerlikon-Bührle Group. On 8 April 2009, the federal court in New York allowed parts of the aiding-and-abetting allegations against Rheinmetall to survive the motion-to-dismiss stage. On 26 December 2013, the case against Rheinmetall was dismissed because of its insufficient connection to the United States and the limits on extraterritorial application of the Alien Tort Statute. The 2014 decision records this conclusion of the proceedings.
