The Savoia-Marchetti S.74 was a four-engine airliner developed by Savoia-Marchetti for Ala Littoria. The prototype first flew on 16 November 1934. Only three were ever built. The aircraft were used in passenger service. On 22 December 1937, one broke the speed record over 1,000 kilometres (620 mi), at 322.089 km/h (200.137 mph). When Italy entered World War II in 1940, they were put into service as military transport aircraft for the Regia Aeronautica. None of the three survived the war.
