It was the first aircraft designed for CAMS by Raffaele Conflenti after he had been recruited by the company from his previous job at Società Idrovolanti Alta Italia (SIAI).

It was a conventional design for the era featuring a two-bay equal-span unstaggered biplane wing cellule.

The prototype was exhibited at the 1922 Salon de l'Aéronautique and evaluated the following year by the Aéronautique Maritime.

In August 1924, Ernest Burri used this machine to break the world air speed record for a passenger-carrying seaplane.
