Design and description
The Acciaio-class submarines were designed as improved versions of the preceding Adua class. They displaced 697 metric tons (686 long tons) surfaced and 850 metric tons (840 long tons) submerged. The submarines were 60.18 meters (197 ft 5 in) long, had a beam of 6.44 meters (21 ft 2 in) and a draft of 4.78 meters (15 ft 8 in).[1]
For surface running, the boats were powered by two 700-
propeller shaft. When submerged each propeller was driven by a 400-horsepower (298 kW) electric motor. They could reach 14 knots (26 km/h; 16 mph) on the surface and 7.3 knots (13.5 km/h; 8.4 mph) underwater. On the surface, the Acciaio class had a range of 5,000 nautical miles (9,300 km; 5,800 mi) at 8.5 knots (15.7 km/h; 9.8 mph), submerged, they had a range of 80 nmi (150 km; 92 mi) at 3 knots (5.6 km/h; 3.5 mph).[2]
The boats were armed with six internal 53.3 cm (21.0 in)
13.2 mm (0.52 in) machine guns.[1]
Construction and career
Acciaio was built in
Operation Husky, the invasion of Sicily. On 13 July 1943, Acciaio was sunk by the British submarine Unruly with the loss of her entire crew of 46.[3]
