The S.72 prototype bomber/transport flew in 1932. Powered by three 410kW Pegasus II radials, it followed the popular high-wing, fixed landing-gear formula of the time. An altitude record with 5,000kg payload was established in June 1934. The Nanking Chinese government bought 20 production aircraft with defensive dorsal turret and ventral step machine-gun posts, but nothing was heard of them in action against the Japanese.
