The Aventurier-class ships were significantly larger and more heavily armed than other French destroyers of the period. The ships had an overall length of 88.5m (290.4feet), a beam of 8.6m (28.2feet), and a draft of 3.1m (10.2feet). They displaced 930t at normal load and at deep load. Their crew numbered 140 men.[1]
The ships were powered by a pair of Rateau steam turbines, each driving one propeller shaft using steam provided by five mixed-firing Foster-Wheeler boilers. The engines were designed to produce 18000shp which was intended to give the ships a speed of 32kn. The ships carried of coal and of fuel oil that gave them a range of 1850nmi at a cruising speed of .[2]
The primary armament of the Aventurier-class ships consisted of four 100mm guns in single mounts, one on the forecastle, one between the funnels, and two on the quarterdeck, in front and behind the searchlight platform. They were fitted with a 47mm AA gun for anti-aircraft defence. The ships were also equipped with four single mounts for 450mm torpedo tubes amidships.[1]
