The Glauco class was a pair of submarines ordered by the Portuguese government, but were taken over and completed for the Regia Marina (Royal Italian Navy) during the 1930s. They played a minor role in the Spanish Civil War of 1936–1939 supporting the Spanish Nationalists.
Design and description
The Glauco-class submarines were improved versions of the preceding Squalo class. They displaced 1,071 metric tons (1,054 long tons) surfaced and 1,326 metric tons (1,305 long tons) submerged. The submarines were 73 meters (239 ft 6 in) long, had a beam of 7.2 meters (23 ft 7 in) and a draft of 5.12 meters (16 ft 10 in).[1]
For surface running, the boats were powered by two 1,500-
propeller shaft. When submerged each propeller was driven by a 600-horsepower (447 kW) electric motor. They could reach 17 knots (31 km/h; 20 mph) on the surface and 8 knots (15 km/h; 9.2 mph) underwater. On the surface, the Glauco class had a range of 9,760 nautical miles (18,080 km; 11,230 mi) at 8 knots (15 km/h; 9.2 mph); submerged, they had a range of 110 nmi (200 km; 130 mi) at 3 knots (5.6 km/h; 3.5 mph).[2]
The boats were armed with eight internal 53.3 cm (21 in)
13.2 mm (0.52 in) machine guns.[1]
