Between 20 January and 5 February 1927 Dornier Chief Pilot Richard Wagner established twelve world records for seaplanes with a new R4 Gas Superwal. This aircraft and eleven more with Gnome et Rhône Bristol-Jupiter engines (R4 Gas) or 525 hp Siemens-Bristol-Jupiter engines (R4 Sas) were delivered to the Italian airline Società Anonima Navigazione Aerea (SANA) and Luft Hansa during 1928 and ‘29. Apart from their use by Luft Hansa, six Superwals saw regular service with SANA into the early 1930s on a route along the Italian west coast and on to Spain. Three aircraft were lost during their service. The Superwal I-RUDO (equipped with Isotta Fraschini Asso 500 engines) went into service with the Italian Air Ministry in 1934 and became the last Superwal in Italian service. At least one aircraft was assembled in Spain by CASA.
