Two words (regarding the SM.79). Mediterranean event. Oh ... lookie .... another reason.

The SM.79 trimotor torpedo bomber emerged as Italy’s most important attack aircraft in the MediterraneanAs the struggle between Allied and Axis forces for control of the Mediterranean Sea reached its climax in August 1942, the British Royal Navy launched one of the most formidable efforts to resupply the besieged island of Malta.

Between 1940 and 1943, the SM.79 stormi (wings) based in Sicily, Sardinia and Libya were constantly in action against British warships and merchant vessels. In fact, they participated in all major air campaigns in the Mediterranean, providing pinpoint bombing during the Axis invasions of Crete and Greece, the siege of Malta and the North African campaign, including the Battle of El Alamein. Torpedo-armed SM.79s either sank or damaged 20 warships, and 19 enemy merchant ships were put out of action and their cargo destroyed. It is estimated that SM.79s were responsible for destroying as much as 320,000 tons of enemy shipping, a remarkable achievement even in comparison to the tally of larger torpedo bomber fleets.
