'''''Comandante Faà di Bruno''''', also referred to by its shortened name ''Faà di Bruno'', was a {{sclass|Marcello|submarine}} built for the [[Royal Italian Navy]] (''Regia Marina'') in the 1930s. It was sunk in 1940 by British and Canadian [[destroyer]]s escorting a convoy.

==Design and description==
The ''Marcello''-class submarines were designed as improved versions of the preceding {{sclass|Glauco|submarine|4}}. They [[Displacement (ship)|displaced]] {{convert|1043|t|LT|sp=us}} surfaced and {{convert|1290|t|LT|sp=us}} submerged. The submarines were {{convert|73|m|ftin|sp=us}} long, had a [[beam (nautical)|beam]] of {{convert|7.19|m|ftin|sp=us}} and a [[draft (hull)|draft]] of {{convert|5.1|m|ftin|sp=us}}.<ref name=c5>Chesneau, p. 305</ref>

For surface running, the boats were powered by two {{convert|1800|bhp|lk=in|0|adj=on}} [[diesel engine]]s, each driving one [[propeller shaft]]. When submerged each propeller was driven by a {{convert|550|hp|0|adj=on}} [[electric motor]]. They could reach {{convert|17.4|kn|lk=in}} on the surface and {{convert|8|kn}} underwater. On the surface, the ''Marcello'' class had a range of {{convert|7500|nmi|lk=in|abbr=on}} at {{convert|9.4|kn}}, submerged, they had a range of {{convert|120|nmi|abbr=on}} at {{convert|3|kn}}.<ref>Bagnasco, p. 158</ref>

The boats were armed with eight internal {{convert|53.3|cm|in|1|abbr=on|sp=us}} [[torpedo tube]]s, four each in the bow and stern. One reload were stowed for each tube, which gave them a total of sixteen [[torpedo]]es. They were also armed with two [[Škoda 10 cm K10#OTO 100.2F47 History|{{convert|100|mm|in|abbr=on|0}}]] guns and four [[Breda Model 1931 Machine Gun|{{convert|13.2|mm|in|abbr=on}}]] machine guns for combat on the surface.<ref name=c5/>

==Construction and career==
It was sunk on 8 November 1940 by a combined effort from the destroyers {{HMCS|Ottawa|H60|6}} of the [[Royal Canadian Navy]], and {{HMS|Harvester|H19|6}} of the [[Royal Navy]] after attacking [[Convoy HX 84]] they were defending.<ref>Rohwer, p. 48</ref>
