Cantieri Riuniti dell'Adriatico ("CANT") was responsible for the excellent Italian floatplane design that was the CANT Z.506 Airone ("Heron") series of the 1930s. The aircraft emerged from a commercial development which set about rewriting world aviation speed and distance records concerning aircraft of this class. The Z.506 began life as a commercial airliner shuttling persons over Italian Mediterranean routes before being adopted into service with the Italian Navy prior to and during World War 2 as a maritime patrol and bombing/torpedo platform. The aircraft managed an existence in the post-war world as well, her qualities proving useful in the at-sea rescue role.
The CANT Z.506 offered up a very unique design appearance making her one of the more recognizable aircraft of the period. This was primarily due to her tri-motor configuration in which engine nacelles were affixed to both wing leading edges as well as the fuselage nose. The fuselage was well-streamlined from nose to tail, the latter capped by a conventional single-rudder tail unit. The fuselage sat atop a network of reinforced struts which attached it to a pair of long-running floats allowing for sea-based landings and take offs. The design was clean and well thought out for the period, combining a wooden understructure with canvas-and-wood skinning techniques which made it strong, light and cost-effective - only the floatplanes were actually constructed of more expensive metal. First flight was recorded on August 19th, 1935 with the prototype (powered by 3 x Piaggio P.IX radial piston engines of 610 horsepower each) giving rise to the original commercial model designated as the "Z.506A". The aircraft was formally introduced in 1936.
