The '''''Calvi'' class''' was a [[ship class|class]] of three [[submarine]]s built by Oderno-Terni-Orlando in [[Genoa]] for the [[Royal Italian Navy]] ({{lang-it|Regia Marina}}). The submarines were built in 1935, and all three served in the Mediterranean at the start of the [[Second World War]]. The boats were transferred to the [[BETASOM]] Atlantic submarine base at [[Bordeaux]] in August 1940. In December 1941 the boats were used for a rescue mission of 254 sailors from the sunken {{ship|German auxiliary cruiser|Atlantis}}. After ''Calvi'' had been sunk, ''Finzi'' and ''Tazzoli'' were selected for conversion to "[[Merchant submarine|transport submarine]]s" 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>

==Design and description==
The ''Calvi'' class was an improved and enlarged version of the preceding {{sclass|Balilla|submarine|0}} [[submarine cruiser]]s. They [[Displacement (ship)|displaced]] {{convert|1525|LT|t|sp=us|lk=on|order=flip|0}} surfaced and {{convert|2028|LT|t|sp=us|order=flip|0}} submerged. The submarines were {{convert|84.3|m|ftin|sp=us}} long, had a [[beam (nautical)|beam]] of {{convert|7.7|m|ftin|sp=us}} and a [[draft (hull)|draft]] of {{convert|5.2|m|ftin|sp=us}}.<ref name=c5/> They had an [[Submarine depth ratings|operational diving depth]] of {{convert|90|m|sp=us}}.<ref name=b4/><ref name=c5/> They had an [[Submarine depth ratings|operational diving depth]] of {{convert|90|m|sp=us}}.<ref name=b4/> Their crew numbered 77 officers and enlisted men.<ref name=c5>Chesneau, p. 305</ref>

For surface running, the boats were powered by two {{convert|2200|bhp|lk=on|0|adj=on}} [[diesel engine]]s, each driving one [[propeller shaft]]. When submerged each propeller was driven by a {{convert|900|hp|0|adj=on}} [[electric motor]]. They could reach {{convert|16.8|kn|lk=in}} on the surface and {{convert|7.4|kn}} underwater. On the surface, the ''Calvi'' class had a range of {{convert|11400|nmi|lk=in}} at {{convert|8|kn}}; submerged, they had a range of {{convert|120|nmi|abbr=on}} at {{convert|3|kn}}.<ref name=b4>Bagnasco, p. 152</ref>

The boats were armed with eight {{convert|53.3|cm|in|0|adj=on|sp=us}} [[torpedo tube]]s, four each in the bow and in the stern for which they carried a total of 16 [[torpedo]]es. They were also armed with a pair of [[120 mm Italian naval gun#45-calibre OTO 1931|{{convert|120|mm|adj=on|sp=us}}]] [[deck guns]], one each fore and aft of the [[conning tower]], for combat on the surface. Their [[Anti-aircraft warfare|anti-aircraft armament]] consisted of two twin-gun mounts for [[Breda Model 1931 Machine Gun|{{convert|13.2|mm|in|adj=on|sp=us}}]] [[machine gun]]s.<ref name=c5/>

===''Giuseppe Finzi''===
''Giuseppe Finzi'' (pennant number FZ) was launched 29 June 1935.<ref name="k&p"/> The first war patrol was from [[Cagliari]] to the Atlantic, and lasted from 5 June to 10 July 1940. ''Finzi'' sailed on 7 September 1940 and passed the [[Strait of Gibraltar]] on 13 September for an Atlantic patrol to Bordeaux on 29 September. Admiral [[Karl Dönitz]] visited ''Finzi'' on 30 September to welcome ''[[Regia Marina]]'' sailors to the German base. The third patrol near the British Isles from 24 October to 4 December 1940 revealed that the diesel engine air intake was too exposed for North Atlantic winter weather. The fourth patrol was near the Canary Islands from 10 March to 17 April 1941 and the fifth patrol was off Gibraltar in August. During the sixth patrol from 7 to 29 December 1941 ''Calvi'', ''Finzi'' and ''Tazzoli'' rescued sailors of the sunken raider ''Atlantis''. ''Finzi'' sailed for [[Operation Neuland]] on 6 February 1942 and returned on 31 March. ''Finzi'' returned to the [[Caribbean Sea]] for an eighth patrol from 6 June to 18 August 1942. On 26 November 1942 ''Finzi'' sailed for a ninth patrol to Brazil; but mechanical problems required return to base on 10 December. ''Finzi'' patrolled the west African coast from 11 February to 18 April 1943. Conversion to a transport submarine was never completed, and the boat was seized by the Germans on 9 September 1943 when [[Armistice of Cassibile|Italy surrendered]] to the [[Allies of World War II|Allies]].

The Calvi class was a class of three submarines built by Oderno-Terni-Orlando in Genoa for the Royal Italian Navy (Italian: Regia Marina). The submarines were built in 1935, and all three served in the Mediterranean at the start of the Second World War. The boats were transferred to the BETASOM Atlantic submarine base at Bordeaux in August 1940. In December 1941 the boats were used for a rescue mission of 254 sailors from the sunken German auxiliary cruiser Atlantis. After Calvi had been sunk, Finzi and Tazzoli were selected for conversion to "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 guns.[1]

Design and description[edit]

The Calvi class was an improved and enlarged version of the preceding Balilla-class submarine cruisers. They displaced 1,549 metric tons (1,525 long tons) surfaced and 2,061 metric tons (2,028 long tons) submerged. The submarines were 84.3 meters (276 ft 7 in) long, had a beam of 7.7 meters (25 ft 3 in) and a draft of 5.2 meters (17 ft 1 in).[2] They had an operational diving depth of 90 meters (300 ft).[3][2] They had an operational diving depth of 90 meters (300 ft).[3] Their crew numbered 77 officers and enlisted men.[2]

For surface running, the boats were powered by two 2,200-brake-horsepower (1,641 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 900-horsepower (671 kW) electric motor. They could reach 16.8 knots (31.1 km/h; 19.3 mph) on the surface and 7.4 knots (13.7 km/h; 8.5 mph) underwater. On the surface, the Calvi class had a range of 11,400 nautical miles (21,100 km; 13,100 mi) at 8 knots (15 km/h; 9.2 mph); submerged, they had a range of 120 nmi (220 km; 140 mi) at 3 knots (5.6 km/h; 3.5 mph).[3]

The boats were armed with eight 53.3-centimeter (21 in) torpedo tubes, four each in the bow and in the stern for which they carried a total of 16 torpedoes. They were also armed with a pair of 120-millimeter (4.7 in) deck guns, one each fore and aft of the conning tower, for combat on the surface. Their anti-aircraft armament consisted of two twin-gun mounts for 13.2-millimeter (0.52 in) machine guns.[2]

Ships[edit]

Pietro Calvi[edit]

Pietro Calvi (pennant number CV) was launched 31 March 1935.[2] During the Spanish Civil War, she unsuccessfully fired a pair of torpedoes each at the 6,942-gross register ton (GRT) mail steamer SS Villa de Madrid and the 3946 GRT mail steamer SS Ciudad de Barcelona during a patrol on 1–17 January 1937. During the night of 12/13 January she bombarded the port of Valencia.[4]

The first patrol during the Second World War was from Liguria to the Atlantic Ocean, and lasted from 3 July to 6 August 1940. After overhaul at La Spezia, Calvi sailed on 6 October 1940 for a second Atlantic patrol reaching Bordeaux on 23 October. Calvi suffered storm damage during its third patrol off the British Isles from 3 to 31 December 1940. The fourth patrol was between the Canary Islands and the Azores from 31 March to 13 May 1941. Calvi sailed on 1 August 1941 for a fifth patrol off the Canary Islands. During the sixth patrol from 7 to 29 December 1941 Calvi, Finzi and Tazzoli rescued sailors of the sunken raider Atlantis. The seventh patrol was off Brazil from 7 March to 29 April 1942. Calvi sailed on 2 July 1942 for its eighth patrol.[5] Calvi was rammed and sunk on 14 July 1942 by convoy SL 115 escort HMS Lulworth.[6] Three officers and 32 sailors survived.[5]

Giuseppe Finzi[edit]

Giuseppe Finzi (pennant number FZ) was launched 29 June 1935.[2] The first war patrol was from Cagliari to the Atlantic, and lasted from 5 June to 10 July 1940. The submarine sailed on 7 September 1940 and passed the Strait of Gibraltar on 13 September for an Atlantic patrol to Bordeaux, France, on 29 September. Admiral Karl Dönitz visited Giuseppe Finzi on 30 September to welcome Regia Marina sailors to the German base. The third patrol near the British Isles from 24 October to 4 December 1940 revealed that the diesel engine air intake was too exposed for North Atlantic winter weather. The fourth patrol was near the Canary Islands from 10 March to 17 April 1941 and the fifth patrol was off Gibraltar in August. During the sixth patrol from 7 to 29 December 1941 Pietro Calvi, Giuseppe Finzi and Enrico Tazzoli rescued sailors of the sunken German commerce raider Atlantis. The submarine sailed for Operation Neuland on 6 February 1942 and returned on 31 March. She returned to the Caribbean Sea for an eighth patrol from 6 June to 18 August 1942. On 26 November 1942 Giuseppe Finzi sailed for a ninth patrol to Brazil; but mechanical problems required return to base on 10 December. The boat patrolled the West African coast from 11 February to 18 April 1943. Conversion to a transport submarine was never completed, and the boat was seized by the Germans on 9 September 1943 when Italy surrendered to the Allies. Renamed UIT21 in German service, she was scuttled at Le Verdon-sur-Mer on 25 August 1944 to prevent her capture by advancing Allied forces.[7][8]

Enrico Tazzoli[edit]

For other Italian submarines, see Italian submarine Enrico Tazzoli.

Enrico Tazzoli (pennant number TZ) was launched 14 October 1935.[2] It was named after Enrico Tazzoli, a martyr of the Italian wars of independence. The first wartime patrol was off the coast of North Africa from 21 June to 2 July 1940. The second was an unsuccessful attempt to pass the Strait of Gibraltar from 30 July to 9 August 1940. After overhaul at La Spezia, Enrico Tazzoli sailed on 2 October 1940 and passed the Strait of Gibraltar on 7 October for an Atlantic patrol to Bordeaux on 24 October. The fourth patrol was off the British Isles from 13 December 1940 to 6 January 1941. The boat sailed on 7 April 1941 to patrol between Freetown and the Azores; and shot down an attacking Bristol Blenheim while returning to port on 23 May.
