The S.O.1221S Djinn was the twin-seat production version of the SO.1220 that had been flown originally to evaluate the cold jet method of powering the main rotor blades. In many references it is referred to as the Sud SO.1221 as Sud took over responsibility for the type after taking over SNCASO.
The primary operator was the French Aviation Légère de l'Armée de Terre with a small number operated by the Federal German Heeresfligerei.
