The '''''Marcello'' class''' was a [[ship class|class]] of nine [[submarine]]s built in 1937 and 1938 by [[Cantieri Riuniti dell' Adriatico|CRDA]] in [[Trieste]] for the [[Royal Italian Navy]] ({{langx|it|Regia Marina}}). Two similar submarines built in 1939 at [[La Spezia]] by [[Oto Melara]] are sometimes considered part of the class.  All eleven served in the [[Mediterranean Sea]] at the start of the [[Second World War]]. After {{ship|Italian submarine|Provana||2}}{{'}}s 1940 sinking, the remaining boats were transferred to the [[BETASOM]] Atlantic submarine base at [[Bordeaux]] in August 1940.  After four boats had been sunk in the Atlantic, {{ship|Italian submarine|Barbarigo||2}} and {{ship|Italian submarine|Comandante Cappellini||2}} were then selected for conversion to "[[Merchant submarine|transport submarines]]" in order to exchange rare or irreplaceable trade goods with [[Japan]]. Cargo capacity of 160 tons reduced reserve buoyancy from 20–25% to 3.5–6%; and armament was reduced to defensive [[machine gun]]s.<ref>Brice pp.129&131</ref> Only {{ship|Italian submarine|Dandolo||2}} was in operational condition at the end of the war.

== Class members ==

===''Lorenzo Marcello''===
{{ship|Italian submarine|Lorenzo Marcello||2}} ([[pennant number]] ML) was [[Ceremonial ship launching|launched]] on 20 November 1937<ref name="k&p">Kafka & Pepperburg pp. 790 & 791</ref> and completed on 5 March 1938.  When Italy declared war, ''Marcello'' was temporarily disabled by [[air conditioning]] system leaks. Leakage of [[chloromethane]] refrigerants during submerged operations had caused [[central nervous system]] poisoning of the crew. After unsuccessful patrols in the Mediterranean, ''Marcello'' sailed on 31 October 1940 and passed the [[Strait of Gibraltar]] on 5 November for an Atlantic patrol to [[Bordeaux]] on 2 December.  ''Marcello'' sank one ship on its first BETASOM patrol and was lost to unknown causes on its next patrol in late February 1941.<ref name="marcello">{{cite web|url=http://www.regiamarina.net/detail_text_with_list.asp?nid=84&lid=1&cid=26|title=Regia Marina Italiana|publisher=Cristiano D'Adamo|access-date=2012-08-12}}</ref>

''Dandolo'' sank one ship and damaged another en route to Bordeaux. After an unsuccessful patrol, ''Dandolo'' sank one ship on its second BETASOM patrol. After another unsuccessful patrol, ''Dandolo'' sailed from Bordeaux on 26 June, passed the Strait of Gibraltar on 2 July, and returned to [[Naples]] on 7 July. ''Dandolo'' spent the remainder of the war in the Mediterranean damaging a neutral French [[Tanker (ship)|tanker]] on 4 November 1941, sinking the neutral Spanish freighter ''Castillo Oropesa'' on 8 November 1941, and damaging the [[cruiser]] {{HMS|Cleopatra|33|6}} on 16 July 1943.

After an unsuccessful Mediterranean patrol, ''Veniero'' passed the Strait of Gibraltar on 7 July 1940 for an Atlantic patrol near the [[Canary Islands]] and returned past Gibraltar on 27 July.  This was the first [[Axis powers|Axis]] submarine to pass Gibraltar during [[World War II]], and the report of conditions delivered upon return to Naples on 1 August assisted future attempts to pass the strait. ''Veniero'' sailed on 28 September 1940 and passed the Strait of Gibraltar for an Atlantic patrol to Bordeaux on 2 November.  After sinking two ships in six BETASOM patrols, ''Veniero'' sailed from Bordeaux on 8 August 1941 and returned through the Strait of Gibraltar to La Spezia on 2 September.  On its seventh patrol after return to the Mediterranean, ''Veniero'' was assumed sunk (identification not confirmed) by a [[Consolidated PBY Catalina]] on 7 June 1942.<ref name="veniero">{{cite web|url=http://www.regiamarina.net/detail_text_with_list.asp?nid=84&lid=1&cid=49|title=Regia Marina Italiana|publisher=Cristiano D'Adamo|access-date=2012-08-13}}</ref>

[[Italian submarine Barbarigo|''Agostino Barbarigo'']] (pennant number BO) was launched 12 June 1938.<ref name="k&p"/>  After unsuccessful patrols in the Mediterranean, ''Barbarigo'' sailed on 13 August 1940 and passed the Strait of Gibraltar for an Atlantic patrol to Bordeaux on 8 September.  After unsuccessful BETASOM patrols from 14 October to 13 November 1940 and from 10 February to 8 March 1941, ''Barbarigo'' damaged the British freighter ''Manchester Port'' on 15 May 1941. ''Barbarigo'' sank two ships on its fourth BETASOM patrol.  After an unsuccessful patrol from 22 October to 12 November 1941, ''Barbarigo'' sank the neutral Spanish freighter ''Navemar'' on 23 January 1942.  ''Barbarigo'' sank one ship and damaged another during its seventh BETASOM patrol. Following an encounter with cruisers {{USS|Omaha|CL-4|6}} and {{USS|Milwaukee|CL-5|6}} coming to assist the damaged ship, Captain Grossi notoriously asserted he had sunk a [[battleship]] of the [[United States Navy]]. On the following patrol, a similarly unsuccessful launch of torpedoes at the {{sclass2|Flower|corvette}} HMS ''Petunia'' was reported as the sinking of another battleship.  ''Barbarigo'' sank two [[Allies of World War II|Allied]] ships and another neutral Spanish freighter ''Monte Igueldo'' on its ninth BETASOM patrol.<ref name="barbarigo">{{cite web|url=http://www.regiamarina.net/detail_text_with_list.asp?nid=84&lid=1&cid=9|title=Regia Marina Italiana|publisher=Cristiano D'Adamo|access-date=2012-08-13}}</ref>  After conversion to a transport submarine, ''Barbarigo'' sailed from Bordeaux on 17 June 1943 and was sunk by aircraft in the Bay of Biscay.<ref name="brice131">Brice pp.131-133</ref>
