The Savoia-Marchetti SM.79 Sparviero (Italian for sparrowhawk) was a three-engined Italian medium bomber with a wood-and-metal structure. Originally designed as a fast passenger aircraft, between 1937 and 1939 this low-wing monoplane set 26 world records, qualifying it for some time as the fastest medium bomber in the world. It first saw action during the Spanish Civil War and flew on all fronts in which Italy was involved during World War II. It achieved success as a torpedo bomber in the Mediterranean theater, and became the best-known Italian aeroplane of the war. It was easily recognizable due to its distinctive fuselage dorsal “hump”, and was well liked by its crews, who nicknamed it il gobbo maledetto (“damned hunchback”). It was the most numerous Italian bomber of World War II, with some 1,300 built, remaining in Italian service until 1952.
