High Quality Content by WIKIPEDIA articles! The Savoia-Marchetti SM.82 was an Italian bomber and transport aircraft of World War II. It was a cantilever, mid-wing monoplane trimotor with a retractable, tailwheel undercarriage. About 400 were built, the first entering service in 1940, but although able to operate as a bomber with a maximum bombload of up to 8,818 lb (4000 kg), the SM.82 saw very limited use in this role.
