The RSA is one of the earliest surface-to-air missiles systems developed by the Swiss companies Oerlikon-Bührle and Contraves starting in 1947. The missile went through a rapid development process with several upgraded versions and was the first anti-aircraft missile offered for commercial sale when it was placed on the market in the RSC-50 form. The US tested 25 of the slightly different RSC-51 model under the name MX-1868. No further sales were forthcoming.
