The Savoia-Marchetti SM.81 first saw combat during the Second Italo-Abyssinian War where it showed itself to be versatile serving as a bomber transport and reconnaissance aircraft. SM.81s also fought in the Spanish Civil War with the Aviazione Legionaria and were among the first aircraft sent by the fascist powers to aid Francisco Franco. In spite of their obsolescence when Italy became involved in the Second World War approximately 300 SM.81s were in service with the Regia Aeronautica.
