Overview
The Marcello type submarines were an evolution of the large Glauco-class submarines initially ordered by Portugal but absorbed into the Italian fleet due to contract termination. The design was successful, featuring excellent maneuverability, speed, and armament, leading to an order of 11 vessels of this type. These were single-hull submarines with side bulges. In Italian classification, they were categorized as 'large cruiser' (or 'ocean-going') submarines. Giacomo Nani was built at the CRDA shipyard in Monfalcone and entered service in September 1938, assigned to the 2nd submarine squadron. At the outbreak of World War II, Nani completed three unsuccessful patrols in the Mediterranean before being transferred to the Atlantic in autumn 1940. During its fourth patrol, the submarine sank a Swedish coal transport. Giacomo Nani went missing during its fifth patrol in early January 1941.
