The prototype S.61 was evaluated by the French Air Force alongside the S.51 as a potential new fighter, but like its stablemate, was rejected.

About 30 were built in Poland, by the CWL (Centralne Warszaty Lotnicze - Central Aviation Workshops, a predecessor of PZL).

An S.61 was also used by Jean Callizo in his fraudulent attempt on the world altitude record that saw him stripped of his Légion d'Honneur.

A Polish S.61 placed second in the Capitaine Echard race at the Zürich aerial meeting in 1927.
