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.[1] The S.700 was a high-wing cantilever monoplane with the ability to land on water or use a retractable tricycle landing gear.[1] 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.[1] It was planned that the aircraft could use the Italian Alfa Romeo AR-318 turboprop with three-bladed tractor propellers.[1] 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 1,300 l (343 US gal) of water or retardants.[1]
