In 1947, the swiss companies Oerlikon-Bührle & Co. and Contraves AG began the development of a guided short-range surface-to-air missile. The initial production-ready version was the RSC-50, development of which was completed in 1950 (as indicated by the digits in the designation). This missile was actually the world's first commercially available anti-aircraft guided missile. In 1952, the U.S. Air Force evaluated 25 examples of the slightly improved, but otherwise very similar, RSC-51 at Holloman AFB under the project designation MX-1868.

The RSC-51 was launched from a mobile trailer and powered by a liquid-fueled rocket engine. It used a beam-riding guidance system developed by Brown-Boveri. The tracking radar and beam transmitter were located on a second trailer. The missile was equipped with four small fixed stabilizing wings, and was steered by exhaust-deflection control vanes. The RSC-51's high-explosive warhead was detonated by a proximity fuze.
No details about the USAF's evaluation of the MX-1868/RSC-51 missile are available, but the weapon was not further procured by the U.S. military. However, in the international market later models of the Oerlikon/Contraves missiles (RSC-54, RSC-56, RSC-57 and RSC/RSD-58) were reasonably successful, having been used by Switzerland, Italy, Sweden and Japan (usually as a training missile only, though).
