Design and description
The Bandiera class was an improved and enlarged version of the preceding Pisani-class submarines. They displaced 940 metric tons (925 long tons) surfaced and 1,097 metric tons (1,080 long tons) submerged. The submarines were 69.8 meters (229 ft 0 in) long, had a beam of 7.3 meters (23 ft 11 in) and a draft of 5.26 meters (17 ft 3 in).[1] They had an operational diving depth of 90 meters (300 ft).[2] Their crew numbered 53 officers and enlisted men.[1]
For surface running, the boats were powered by two 1,500-brake-horsepower (1,119 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 650-horsepower (485 kW) electric motor. They could reach 15 knots (28 km/h; 17 mph) on the surface and 8.2 knots (15.2 km/h; 9.4 mph) underwater.[2] On the surface, the Bandiera class had a range of 4,750 nautical miles (8,800 km; 5,470 mi) at 8.5 knots (15.7 km/h; 9.8 mph); submerged, they had a range of 60 nmi (110 km; 69 mi) at 4 knots (7.4 km/h; 4.6 mph).[2]
The boats were armed with eight 53.3-centimeter (21 in) torpedo tubes, four each in the bow and stern for which they carried a total of 12 torpedoes. They were also armed with a single 102-millimeter (4 in) deck gun forward of the conning tower for combat on the surface. Their anti-aircraft armament consisted of two 13.2-millimeter (0.52 in) machine guns.[1][2]
