The CANT 6 was a flying boat designed for Italian military service in 1925. It was a large biplane of conventional design with three engines mounted in nacelles within the interplane gap. Only a single example was produced in its original military configuration, followed by two further aircraft redesigned as 11-seat passenger aircraft. One of these was retained by CANT, but the other entered airline service with SocietÃÂ Italiana Servizi Aerei.
