The Sirio class (also known as the Saffo classFirst World War.
Design
In 1904, work began at the German shipyard of
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][5] which corresponded to an in-service sea speed of about 21 knots (39 km/h; 24 mph).[4][c] Sufficient coal was carried to give a range of 598 nmi (688 mi; 1,107 km) at 23 kn (26 mph; 43 km/h) or 1,920 nmi (2,210 mi; 3,560 km) at 8 kn (9.2 mph; 15 km/h).[7] Displacement was 210 tonnes (207 long tons).[4]
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
First World War, with the remaining ships being rearmed, with two 76 mm anti-aircraft guns replacing the 47 mm guns.[4] A third ship, Saffo was lost after running aground off Turkey on 2 April 1920.[4] The surviving ships were disposed of in 1923.[4]

Notes
- ^ Chesneau and Kolesnik,[1] Fock[2] and the current Italian Navy[3] refer to the class as the Sirio class, while Fraccaroli[4] and Purnell's Illustrated Encyclopedia of Modern Weapons and Warfare[5] 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.[6]
- ^ Speeds of up to 25.7 knots (47.6 km/h; 29.6 mph) were reached during sea trials.[4]
- ^ Fraccaroli swaps the dates and circumstances of the loss of Scorpione and Serpente.[4]
