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.

Development
The S.700 was designed to use as much of the SF.600 as possible to build a twin-engined amphibian, changes required included a stronger wing due to the increased all-up weight. The S.700 was a high-wing cantilever monoplane with the ability to land on water or use a retractable tricycle landing gear. The hull and floats were to be made of composite materials and the engines were to be fitted on the upper surface of the wings to protect against spray. It was planned that the aircraft could use the Italian Alfa Romeo AR-318 turboprop with three-bladed tractor propellers. As well as use as a freighter or general utility aircraft with 12 seats it was also proposed to use it as a water bomber with a capacity for 1300 L of water or retardants.
