The Settembrini class was an improved and enlarged version of the preceding Mameli-classsubmarines. They displaced 953 metric tons (938 long tons) surfaced and 1,153 metric tons (1,135 long tons) submerged. The submarines were 69.11 meters (226 ft 9 in) long, had a beam of 6.61 meters (21 ft 8 in) and a draft of 4.45 meters (14 ft 7 in).[1] They had an operational diving depth of 80 meters (260 ft).[2] Their crew numbered 56 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 700-horsepower (522 kW) electric motor. They could reach 17.5 knots (32.4 km/h; 20.1 mph) on the surface and 7.7 knots (14.3 km/h; 8.9 mph) underwater.[2] On the surface, the Settembrini class had a range of 6,200 nautical miles (11,500 km; 7,100 mi) at 7.3 knots (13.5 km/h; 8.4 mph);[1] submerged, they had a range of 100 nmi (190 km; 120 mi) at 3 knots (5.6 km/h; 3.5 mph).[2]
