The Sirio-class (also known as the Saffo-class[lower-alpha 1]) was a class of six sea-going steam-powered torpedo boats of the of the Italian Regia Marina (Royal Navy) built by the German shipyard Schichau-Werke from 1904–1906. They served in the Italo-Turkish War and the First World War.
Design[]
In 1904, work began at the German shipyard of Schichau-Werke, Elbing (now Elbląg, Poland) on a class of six torpedo-boats for the Italian Navy.[3][lower-alpha 2] They were 50.00 metres (164 ft 1 in) long between perpendiculars and 51.07 metres (167 ft 7 in) overall, with a beam of 6.00 metres (19 ft 8 in) and a draught of 1.60 metres (5 ft 3 in).[1] Two Coal-fired Schultz-Thornycroft boilers fed Vertical triple-expansion steam engines rated at 3,000–3,100 indicated horsepower (2,200–2,300 kW), giving a rated speed of 25 knots (46 km/h; 29 mph),[1][4] which corresponded to an in-service sea speed of about 21 knots (39 km/h; 24 mph).[3][lower-alpha 3] Displacement was 210 tonnes (207 long tons).[3]
Three 450 mm (17.7 in) torpedo tubes were fitted, with a gun armament of three 47 mm guns. The ships had a crew of 38 officers and men.[1]
Service[]
On delivery, the ships of the class equipped the 1st Squadron of High Seas Torpedo Boats, based first at La Spezia and then at Messina.[2] The ships of the class were active during the Italo-Turkish War of 1911–1912,[2] with Spica leading four Pegaso-class torpedo boats on a reconnaissance of the Dardanelles on the night of 18/19 July 1912, penetrating under fire about 18 kilometres (11 mi) before being stopped by a boom across the straits, and then escaping with little damage and no casualties.[6] Two ships, Scorpione and Serpente, were lost following collisions during the First World War, with the remaining ships being rearmed, with two 76 mm anti-aircraft guns replacing the 47 mm guns.[3] A third ship, Saffo was lost after running aground off Turkey on 2 April 1920.[3] The surviving ships were disposed of in 1923.[3]

Notes[]
- ↑ Chesneau and Kolesnik[1] and the current Italian Navy[2] refer to the class as the Sirio-class, while Fraccaroli[3] and Purnell's Illustrated Encyclopedia of Modern Weapons and Warfare[4] refer to the Saffo-class.
- ↑ Work also begun in at the Pattison shipyard of Naples on four torpedo boats of similar size to a design by the British torpedo-craft specialist Thornycroft, the initial members of the Pegaso-class torpedo boat.[5]
- ↑ Speeds of up to 25.7 knots (47.6 km/h; 29.6 mph) were reached during sea trials.[3]
- ↑ Fracarolli swaps the dates and circumstances of the loss of Scorpione and Serpente.[3]
