Domenico Millelire was one of four Balilla-class submarines built for the Regia Marina (Royal Italian Navy) during the late 1920s.

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]
