The Savoia-Marchetti S.72 was an Italian three-engine transport monoplane designed and built by Savoia-Marchetti as an enlarged and strengthened version of the earlier S.71. The S.72 was a three-engine, high-wing cantilever monoplane with a fixed tailwheel landing gear. Designed as a heavy bomber, the prototype was first flown in 1934 powered by three 410 kW (550 hp) Alfa Romeo licence-built Bristol Pegasus radial engines.
