Design and description
The Sauro-class destroyers were enlarged and improved versions of the preceding Sellaclass. [1] They had an overall length of 90.16 meters (296 ft), a beam of 9.2 meters (30 ft 2 in) and a mean draft of 2.9 meters (9 ft 6 in). They displaced 1,058 metric tons (1,041 long tons ) at standard load, and 1,600 metric tons (1,570 long tons) at deep load. Their complement was 8–10 officers and 146 enlisted men. [2]
The Sauros were powered by two Parsons geared steam turbines, each driving one propeller shaft using steam supplied by three Yarrow boilers. The turbines were rated at 36,000 shaft horsepower (27,000 kW ) for a speed of 31 knots (57 km/h; 36 mph) in service, [3] although the ships reached speeds in excess of 36 knots (67 km/h; 41 mph) during their sea trials while lightly loaded. [4] They carried enough fuel oil to give them a range of 2,600 nautical miles (4,800 km; 3,000 mi) at a speed of 14 knots (26 km/h; 16 mph). [1]
Their main battery consisted of four 120-millimeter (4.7 in) guns in two twin-gun turrets, one each fore and aft of the superstructure. [2] Anti-aircraft (AA) defense for the Sauro-class ships was provided by a pair of 40-millimeter (1.6 in) AA guns in single mounts amidships and a pair of 13.2-millimeter (0.52 in) machine guns. They were equipped with six 533-millimeter (21 in) torpedo tubes in two triple mounts amidships. [3] The Sauros could also carry 52 mines. [2]
Operational history
The destroyers were outfitted for colonial service, and by 1935 they were deployed in the naval base of Massawa, Eritrea. [5] Italian's entry in World War II left Italian East Africa isolated from Italy. [6]
Attack on convoy BN 7
The only appreciable action in which the destroyers were involved was the attack on the Allied convoy BN 7, on the first hours of 21 October 1940. Nullo and Sauro, along with Leone and Pantera shelled the convoy and its escort, inflicting some splinter damage to the leading transport ship, and launched at least two torpedoes aimed at HMAS Yarra, which successfully dodged them. [7] The attack was nevertheless repulsed by the cruiser HMS Leander, which fired 129 six-inch rounds on the Italian destroyers. While Sauro and the other destroyers successfully disengaged, Nullo was chased by the destroyer HMS Kimberley and forced to run aground on Harmil island, where she was later wrecked by RAF Blenheim bombers. Kimberley took two hits on a boiler from coastal batteries, and had to be towed to Aden by HMS Leander.
End of the surviving units
The three surviving destroyers remained at dock in Massawa until the very end of ground operations in East Africa. Their commander ordered them to steam out on 2 April 1941, for an almost suicidal attack on Port Sudan. The squadron was soon discovered by British air reconnaissance, and immediately bombed by land-based Swordfish aircraft from the aircraft carrier HMS Eagle. Battisti managed to reach the Arabian coast, where she was scuttled by her crew. Manin and Sauro kept firing their antiaircraft guns until they were sunk by the British planes. [8]
The Turbine-class destroyer was a group of eight destroyers built for the Regia Marina in the 1920s. The ships played a minor role in the Spanish Civil War of 1936–1937, supporting the Nationalists. All the ships of the class were lost during World War II.
The Sella-class destroyers were a group of four destroyers built for the Regia Marina in the 1920s. Two of these ships fought in World War II and both were sunk after the Italian capitulation to the Allies. The two other ships were sold to the Swedish Navy in 1940 and were scrapped in the late 1940s.
The Leone class were a group of destroyers built for the Italian Navy in the early 1920s. Five ships were planned and three completed. All three ships were based at Massawa, Eritrea during World War II and were sunk during the East African Campaign.
The Mirabello class were a group of three destroyers built for the Regia Marina during World War I. Carlo Alberto Racchia was sunk by a mine in the Black Sea during the Allied intervention in the Russian Civil War in 1920. The remaining two ships, obsolescent by 1938, were re-rated as destroyers and participated in World War II. Carlo Mirabello was also lost to a mine while escorting a convoy in 1941. The last surviving ship, Augusto Riboty, was reconfigured as a convoy escort in 1942–1943. The torpedo tubes were removed and depth charges and 20 mm (0.79 in) anti-aircraft guns added. She survived the war and was transferred to the Soviet Union as war reparations in 1946. The ship was scrapped five years later.
Strale was one of four Freccia-class destroyers built for the Regia Marina in the early 1930s. Completed in 1932, she played a minor role in the Spanish Civil War of 1936–1939 supporting the Spanish Nationalists and served in World War II.
Italian destroyer Espero was one of eight Turbine-class destroyers built for the Regia Marina during the 1920s. She was named after a westerly wind, Espero, or Ponente, common in summer in the Mediterranean. Completed in 1928, Espero was sent to Shanghai after the Shanghai Incident on 28 January 1932. After encountering heavy seas, she had to stop at Saigon, French Indochina, then stayed in the Far East even after a truce had been negotiated between China and Japan.
Euro was one of eight Turbine-class destroyers built for the Regia Marina during the 1920s. She was named after Euro, weak winter easterly wind bringing rain and storms to the Mediterranean.
Carabiniere was one of nineteen Soldati-class destroyers built for the Regia Marina in the late 1930s and early 1940s. Completed in 1938, she survived World War II to be scrapped in 1978.
Corazziere was one of nineteen Soldati-class destroyers built for the Regia Marina in the late 1930s and early 1940s. Completed in mid-1939, she was the last of the first batch of a dozen ships to enter service.
Dardo was one of four Freccia-class destroyers built for the Regia Marina in the early 1930s. Completed in 1932, she served in World War II. The ship was captured by the Germans after the Italian armistice in September 1943 and used by the Kriegsmarine under the name TA31 until she was sunk in April 1945.
Francesco Nullo was one of four Sauro-class destroyers built for the Regia Marina in the 1920s. Completed in 1927, she served in World War II.
Cesare Battisti was one of four Sauro-class destroyers built for the Regia Marina in the 1920s. Completed in 1927, she served in World War II.
Daniele Manin was one of four Sauro-class destroyers built for the Regia Marina in the 1920s. Completed in 1927, she served in World War II.
Nazario Sauro was the lead ship of her class of four destroyers built for the Regia Marina in the 1920s. Completed in 1926, she served in World War II.
Quintino Sella was the lead ship of her class of four destroyers built for the Regia Marina in the 1920s. Completed in 1926, she served in World War II.
Francesco Crispi was one of four Sella-class destroyers built for the Regia Marina in the 1920s. Completed in 1927, she served in World War II.
