Design and description

The Balilla-class submarines were the first cruiser submarines built for the Regia Marina. They displaced 1,450 metric tons (1,427 long tons ) surfaced and 1,904 metric tons (1,874 long tons) submerged. The submarines were 86.5 meters (283 ft 10 in) long, had a beam of 7.8 meters (25 ft 7 in) and a draft of 4.7 meters (15 ft 5 in). [1] They had an operational diving depth of 110 meters (360 ft). [2] Their crew numbered 77 officers and enlisted men. [1]

For surface running, the boats were powered by two 2,450- brake-horsepower (1,827  kW ) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 1,100-horsepower (820 kW) electric motor. The submarines were also fitted with an auxiliary diesel cruising engine that gave them a speed of 7 knots (13 km/h; 8.1 mph) on the surface. They could reach a maximum speed of 17.5 knots (32.4 km/h; 20.1 mph) on the surface and 8 knots (15 km/h; 9.2 mph) underwater. On the surface, the Balilla class had a range of 12,000 nautical miles (22,000 km; 14,000 mi) at 7 knots; 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 six internal 53.3-centimeter (21 in) torpedo tubes, four in the bow and two in the stern, for which they carried a dozen torpedoes. They were also armed with a single 120-millimeter (4.7 in) deck gun, forward of the conning tower, for combat on the surface. Their anti-aircraft armament consisted of two 13.2-millimeter (0.52 in) machine guns. [1]

Construction and service

Domenico Millelire was laid down on 26 January 1925 at the Odero-Terni-Orlando shipyard in Muggiano, La Spezia. She was launched on 19 September 1927 and commissioned on 11 August 1928. [3]
