The Branlebas class was a class of ten destroyers built for the French Navy in the first decade of the 20th century. Eight of the ships survived the First World War and were scrapped afterwards.
The Branlebas-class was a development of the previous Claymore-class, and was the final evolution of the 300-tonne type which the French had built since 1899, with their first destroyer class, the Durandal-class. Like all the 300-tonne destroyers, the Branlebas-class had a turtledeck forecastle with a flying deck, raised above the hull, aft.
They were 58 metres (190 ft 3 in) long between perpendiculars, with a beam of 6.28 metres (20 ft 7 in) and a maximum draught of 2.96 metres (9 ft 9 in).Displacement was 350 tonnes (344 long tons). Two coal-fired Normand or Du Temple boilers fed steam at 1,830 kilopascals (265 psi) to two 3-cylinder triple-expansion steam engines, rated at 6,800 indicated horsepower (5,100 kW), and driving two propeller shafts, giving a design speed of 27.5 knots (50.9 km/h; 31.6 mph). Speeds reached during sea trials ranged from 27.09 knots (50.17 km/h; 31.17 mph) for Glaive to 29.82 knots (55.23 km/h; 34.32 mph) for Sape. The ships had a range of 2,100 nautical miles (3,900 km; 2,400 mi) at 10 knots (19 km/h; 12 mph).
