Fratelli Bandiera was the lead ship of her class of four submarines built for the Regia Marina (Royal Italian Navy) during the late 1920s.
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]
Construction and career
Fratelli Bandiera was laid down by Cantiere Navale Triestino at their Trieste shipyard in 1928, launched on 7 August 1929 and completed later that year.[3]
