Comandante Faà di Bruno, also referred to by its shortened name Faà di Bruno, was a Template:Sclass- built for the Royal Italian Navy (Regia Marina) in the 1930s. It was sunk in 1940 by British and Canadian destroyers escorting a convoy.

Design and description

The Marcello-class submarines were designed as improved versions of the preceding Template:Sclass-. They displaced 1,043 metric tons (1,027 long tons) surfaced and 1,290 metric tons (1,270 long tons) submerged. The submarines were 73 meters (239 ft 6 in) long, had a beam of 7.19 meters (23 ft 7 in) and a draft of 5.1 meters (16 ft 9 in).[1]

For surface running, the boats were powered by two 1,800-brake-horsepower (1,342 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 550-horsepower (410 kW) electric motor. They could reach 17.4 knots (32.2 km/h; 20.0 mph) on the surface and 8 knots (15 km/h; 9.2 mph) underwater. On the surface, the Marcello class had a range of 7,500 nmi (13,900 km; 8,600 mi) at 9.4 knots (17.4 km/h; 10.8 mph), submerged, they had a range of 120 nmi (220 km; 140 mi) at 3 knots (5.6 km/h; 3.5 mph).[2]

The boats were armed with eight internal 53.3 cm (21.0 in) torpedo tubes, four each in the bow and stern. One reload were stowed for each tube, which gave them a total of sixteen torpedoes. They were also armed with two 100 mm (4 in) guns and four 13.2 mm (0.52 in) machine guns for combat on the surface.[1]

Construction and career

It was sunk on 8 November 1940 by a combined effort from the destroyers HMCS Ottawa of the Royal Canadian Navy, and HMS Harvester of the Royal Navy after attacking Convoy HX 84 they were defending.[3]
