Armament

The Argo-class was a

Second World War. The boats were transferred to the BETASOM Atlantic submarine base at Bordeaux in 1940, but returned to the Mediterranean in 1941, where both were sunk within a few days of the September 1943 Italian armistice.[1]

Design and description

The Argo-class submarines displaced 793 metric tons (780 long tons) surfaced and 1,016 metric tons (1,000 long tons) submerged. The submarines were 63.15 meters (207 ft 2 in) long, had a beam of 6.93 meters (22 ft 9 in) and a draft of 4.46 meters (14 ft 8 in). Their crew numbered 46 officers and enlisted men.[2]

For surface running, the boats were powered by two 750-

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 8 knots (15 km/h; 9.2 mph) underwater. On the surface, the Argo class had a range of 10,176 nautical miles (18,846 km; 11,710 mi) at 8 knots (15 km/h; 9.2 mph); submerged, they had a range of 100 nmi (190 km; 120 mi) at 3 knots (5.6 km/h; 3.5 mph).[3]

The boats were armed with six internal 53.3-centimeter (21 in)

Velella

Velella (pennant number VL) was launched 18 December 1936[4] and completed on 1 September 1937. Velella was on patrol in the eastern Mediterranean when Italy declared war. After refit at La Spezia, Velella sailed on 25 November 1940 and passed the Strait of Gibraltar on 1 December for an Atlantic patrol to Bordeaux on 25 December. After four unsuccessful Atlantic patrols, Valella returned to the Mediterranean on 24 August 1941. After refit at Cagliari and training at Pula, Velella patrolled without success south of Cape Palos (Spain) in April 1942, south of the Balearic Islands in June, along the Tunisian coast in July, and west of the Island of Galite in August, south of the Balearic Islands in September, in the Gulf of Philippeville and the Bay of Bona in November, north of Cape de Fer in April 1943, and off eastern Sicily in July. Its last patrol was off Salerno, where it was torpedoed by HMS Shakespeare on 7 September 1943. There were no survivors.[6]
