Italian submarine Gondar was an built for the Royal Italian Navy (Regia Marina) during the 1930s. It was named after a city of Gondar in northern Ethiopia. Design and description The Adua-class submarines were essentially repeats of the preceding . They displaced surfaced and submerged. The submarines were long, had a beam of and a draft of . For surface running, the boats were powered by two diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a electric motor. They could reach on the surface and underwater. On the surface, the Adua class had a range of at , submerged, they had a range of at . The boats were armed with six internal torpedo tubes, four in the bow and two in the stern. One reload torpedo was carried for each tube, for a total of twelve. They were also armed with one deck gun for combat on the surface. The light anti-aircraft armament consisted of one or two pairs of machine guns. Construction and career Gondar was launched on 3 October 1937 in OTO's shipyard in La Spezia and commissioned on 28 September 1938. Initially, she was assigned to 14th Squadron based at La Spezia. After intensive training and exercises, in August of 1938 Gondar was reassigned to the III Submarine Group based at Leros. During 1939, Gondar made a long endurance training in the Dodecanese, and in February of 1940 the submarine was temporarily assigned to Messina, and finally in May 1940 she became a part of 15th Squadron (I Submarine group) based at La Spezia. At the outbreak of hostilities she was immediately sent on a mission to patrol an area along the French coast and Gulf of Genoa. She returned to the base on 14 June 1940 without encountering any enemy traffic. After completing two more missions, one 20 miles east of Cape Antibes from 18 to 25 June 1940, and the other off the Strait of Gibraltar from 5 to 16 August 1940, Gondar was moved into Arsenal at La Spezia to convert her into SLC carrying submarine. Three SLC(Siluro a Lunga Corsa which means long running torpedo) units were fitted onto the boat on her deck, two placed side by side in the aft, and one on her bow, the submarine's deck gun was also removed to accommodate SLC units. With a weight of 2.8 tons, these SLC
