Italian cruiser Nino Bixio

Plan and profile drawing of Nino Bixio

Nino Bixio was 140.3 meters (460 ft) long at the waterline, with a beam of 13 m (43 ft) and a draft of 4.1 m (13 ft). She displaced 3,575 long tons (3,632 t) normally and up to 4,141 long tons (4,207 t) at full load. She had a short forecastle deck and a pair of pole masts. Her crew consisted 13 officers and 283 enlisted men.[1]

The ship's propulsion system consisted of three Curtiss steam turbines, each driving a screw propeller. Steam was provided by fourteen mixed coal and oil firing Blechynden boilers, which were vented into four widely spaced funnels. The engines were rated at 23,000 shaft horsepower (17,000 kW) for a top speed of 26.82 knots (49.67 km/h; 30.86 mph). She had a cruising range of 1,400 nautical miles (2,600 km; 1,600 mi) at an economical speed of 13 knots (24 km/h; 15 mph).[1]

The ship was armed with a main battery of six 120 mm (4.7 in) L/50 guns mounted singly.[Note 1] She was also equipped with a secondary battery of six 76 mm (3 in) L/50 guns, which provided close-range defense against torpedo boats. She also carried two 450 mm (17.7 in) torpedo tubes submerged in the hull. Nino Bixio also had a capacity to carry 200 naval mines. The ship was only lightly armored, with a 38 mm (1.5 in) thick deck, and 100 mm (3.9 in) thick plating on her main conning tower.[1]

Nino Bixio, named for the soldier and politician, was built at the Regio Cantiere di Castellammare di Stabia shipyard; her keel was laid down on 15 February 1911, the same day as her sister Marsala. Nino Bixio's completed hull was launched ten months later on 30 December, after which fitting-out work commenced. The ship was completed by 5 May 1914, when she was commissioned into the Italian fleet.[1]

Italy, a member of the Central Powers, declared neutrality at the start of World War I in August 1914, but by May 1915, the Triple Entente had convinced the Italians to enter the war against their former allies.[2] Admiral Paolo Thaon di Revel, the Italian naval chief of staff, believed that Austro-Hungarian submarines could operate too effectively in the narrow waters of the Adriatic, which could also be easily seeded with minefields. The threat from these underwater weapons was too serious for him to use the fleet in an active way.[3] Instead, Revel decided to implement blockade at the relatively safer southern end of the Adriatic with the main fleet, while smaller vessels, such as the MAS boats, conducted raids on Austro-Hungarian ships and installations.[4] Nino Bixio, Marsala, and the cruiser Quarto were based at Brindisi during the war, where they could patrol the path from the narrow Adriatic to the Mediterranean.[5]

In December 1915, an Austro-Hungarian force of two cruisers and five destroyers attempted to intercept transports supplying the Serbian Army trapped in Albania. Quarto departed first, along with the British cruiser HMS Dartmouth and five French destroyers; Nino Bixio followed two hours later with HMS Weymouth and four Italian destroyers. The first flotilla engaged in a running battle with the fleeing Austro-Hungarian cruiser SMS Helgoland but Nino Bixio's group was too far behind to join the fray.[6] By May 1917, the reconnaissance forces at Brindisi had come under the command of Rear Admiral Alfredo Acton.[7] On the night of 14–15 May, the Austro-Hungarian cruisers Helgoland, Novara, and Saida raided the Otranto Barrage—a patrol line of drifters intended to block Austro-Hungarian and German U-boats.[8] She did not participate in the ensuing Battle of the Otranto Straits because she did not have steam up in her boilers when the Italo-British forces counterattacked.[9]

The Regia Marina demobilized after the end of the war in 1918 and the draw-down continued into the 1920s in large part due to severe budgetary shortfalls in the postwar period.[10][11] The engines installed on Nino Bixio and her sister proved to be problematic throughout her time in service, which ultimately cut her career short. She was stricken from the naval register on 15 March 1929 and subsequently broken up for scrap; in contrast, the much more efficient Quarto, which had been built before Nino Bixio, remained in service for another decade.[1]
