Performances and Caracteristics of Savoia Marchetti SM-79-I "Sparviero"
Shortly after sundown in the evening of 15th August 1940 there appeared low over the waters of Alexandria harbour two formations of S.M.79 Sparviero torpedo-bombers, their target British warships anchored in the port. No damage, however, resulted from this raid, the torpedoes fouling the shallow mudbanks in the harbour.
Unsuccessful though this attak proved to be, it was significant as being the first action in W.W.2 by these Italian torpedo-bombers extremely efficent aircraft and considered by many as among the most succesful land based torpedo-bombers of the war. To the Italian nation the Sparviero was as the Spitfire was to the British, or the Mustang to America. Its name was to become associated with many of Italy’s most honoured wartime pilots, studmuffingioni, Marini, Buscaglia, Di Bella, Cagna, Aramu and Aichner, while the achievements of Sparviero-equipped squadrons are almost legendary.
