Design and development

The S.22 was a single-seat twin-engine biplane flying boat. Its two 224 kW (300 hp) Isotta Fraschini V.6bis engines were mounted on eight struts above the hull and below the upper wing, driving two propellers, one in tractor configuration and one in pusher configuration.[1]

Operational history

During test flights over Lake Maggiore prior to the 1921 Schneider trophy races, the S.22 crashed into the lake, ending the hope that it would represent Italy in the race.[2]
