Italian submarine Flutto
Italian submarine
The Italian submarine Flutto was the name ship of her class of submarines built for the Royal Italian Navy (Regia Marina) during World War II. She obtained no successes during her short career, and was sunk by British ships during the Invasion of Sicily in 1943.
Design and description
The Flutto-class submarines were designed as improved versions of the preceding Argo class. They displaced 930 metric tons (920 long tons) surfaced and 1,093 metric tons (1,076 long tons) submerged. The submarines were 63.15 meters (207 ft 2 in) long, had a beam of 6.98 meters (22 ft 11 in) and a draft of 4.87 meters (16 ft 0 in).
For surface running, the boats were powered by two 1,200-brake-horsepower (895 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 16 knots (30 km/h; 18 mph) on the surface and 8 knots (15 km/h; 9.2 mph) underwater. On the surface, the Flutto class had a range of 5,400 nautical miles (10,000 km; 6,200 mi) at 8 knots (15 km/h; 9.2 mph), submerged, they had a range of 80 nmi (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph).
The boats were armed with six internal 53.3 cm (21.0 in) torpedo tubes, four in the bow and two in the stern. One reload were stowed for each tube, which gave them a total of twelve torpedoes.
