Design and description

The Argonauta class was derived from the earlier Squalo-class submarines.[1] They displaced 660 metric tons (650 long tons) surfaced and 813 metric tons (800 long tons) submerged. The submarines were 61.5 meters (201 ft 9 in) long, had a beam of 5.7 meters (18 ft 8 in) and a draft of 4.7 meters (15 ft 5 in).[2] They had an operational diving depth of 80 meters (260 ft).[1] Their crew numbered 44 officers and enlisted men.[2]

For surface running, the boats were powered by two 750-brake-horsepower (559 kW) diesel engines, each driving one 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.[1] On the surface, the Settembrini class had a range of 5,000 nautical miles (9,300 km; 5,800 mi) at 8 knots (15 km/h; 9.2 mph);[2] submerged, they had a range of 110 nmi (200 km; 130 mi) at 3 knots (5.6 km/h; 3.5 mph).[1]

The boats were armed with six 53.3-centimeter (21 in) torpedo tubes, four in the bow and two in the stern for which they carried a total of 12 torpedoes. They were also armed with a single 102-millimeter (4 in) deck gun forward of the conning tower for combat on the surface. Their anti-aircraft armament consisted of two single 13.2-millimeter (0.52 in) machine guns.[2]

Construction and career

Argonauta was laid down by Cantieri Riuniti dell'Adriatico at their Monfalcone shipyard in 1929, launched on 19 January 1931 and completed the following year.[2]
