Osvetnik (Avenger) was the first of the Osvetnik-class diesel-electric submarines built by Ateliers et Chantiers de la Loire, Nantes, France for the navy of the Kingdom of Serbs, Croats and Slovenes (later Yugoslavia). She was launched in 1929, and was built to a partial double hull Simonot design similar to the French Circé-class submarines. She was armed with six 550 mm (22-inch) torpedo tubes, one 100 mm (3.9 in) gun, and one 40 mm (1.6 in) anti-aircraft gun, and could dive to 80 metres (260 ft).
Prior to World War II she participated in several cruises to Mediterranean ports. During the German-led Axis invasion of Yugoslavia in April 1941, she was captured by Italian forces at the Bay of Kotor. Initially designated N1, her armament was changed and her conning tower modified. Due to her age and shallow diving depth, when she was commissioned into the Royal Italian Navy as Francesco Rismondo; her service was limited to training and experimentation. She was scuttled off the island of Corsica by the Germans shortly after her capture in September 1943 following the Italian surrender.
