SIAI-Marchetti S.700 Cormorano

The SIAI-Marchetti S.700 Cormorano was an Italian proposal for a twin-engined amphibian based on the SF.600 Canguro feeder-liner. The design used as much of the SF.600 as possible, with a stronger wing to carry the greater all-up weight. It was a high-wing cantilever monoplane able to land on water or to use a retractable tricycle undercarriage, with the hull and floats to be made of composite materials and the engines mounted on the upper surface of the wings to protect them from spray. The planned power was two Alfa Romeo AR-318 turboprops driving three-bladed reversible propellers. It was proposed as a freighter or utility aircraft with 12 seats and as a water bomber able to carry 1,300 litres of water or retardant.
