Design and description

The Squalo-class submarines were essentially repeats of the preceding Bandiera class. They displaced 920 metric tons (910 long tons) surfaced and 1,125 metric tons (1,107 long tons) submerged. The submarines were 69.8 meters (229 ft) long, had a beam of 7.21 meters (23 ft 8 in) and a draft of 5.19 meters (17 ft).[1] They had an operational diving depth of 90 meters (300 ft).[2] Their crew numbered 53 officers and enlisted men.[1]

For surface running, the boats were powered by two 1,500-brake-horsepower (1,119 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 650-brake-horsepower (485 kW) electric motor. They could reach 15.1 knots (28.0 km/h; 17.4 mph) on the surface and 8 knots (15 km/h; 9.2 mph) underwater. On the surface, the Squalo class had a range of 5,650 nautical miles (10,460 km; 6,500 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).[2]

The boats were armed with eight internal 53.3 cm (21 in) torpedo tubes, four each in the bow and stern. They carried a total of a dozen torpedoes. They were also armed with one 102 mm (4 in) deck gun for combat on the surface. Their anti-aircraft armament consisted of two 13.2 mm (0.52 in) machine guns.[1]

Construction and career

Narvalo, named for the narwhal, was laid down on 17 October 1928 at the Cantieri Riuniti dell'Adriatico (CRDA) shipyard at Monfalcone. She was launched on 15 March 1930 and completed on 6 December.[3]
