Design and description
The Acasta class was based on an enlarged HMS Firedrake, a very fast Yarrow Special of the Acheron class. Ardent was ordered to evaluate William Denny & Brothers' recently developed longitudinal framing method of building which offered greater hull strength for a given weight than conventional transverse construction. The Acastas had an overall length of 267 feet 6 inches (82 m), a beam of 27 feet (8.2 m), and a normal draught of 9 feet 6 inches (2.9 m). The ships displaced 1,072 long tons (1,089 t) at deep load and their crew numbered 73 officers and ratings.
The destroyers were powered by a single Parsons steam turbine that drove two propeller shafts using steam provided by Yarrow boilers. Ardent differed from her sister ships in that she had only three rather than four boilers and only two funnels. The engines developed a total of 24,500 shaft horsepower (18,300 kW) and were designed for a speed of 29 knots (54 km/h; 33 mph). The ship reached a speed of 29.5 knots (54.6 km/h; 33.9 mph) during her sea trials. The Acastas had a range of 1,540 nautical miles (2,850 km; 1,770 mi) at a cruising speed of 15 knots (28 km/h; 17 mph).
The primary armament of the ships consisted of three BL 4-inch (102 mm) Mk VIII guns[Note 1] in single, unprotected pivot mounts. Ardent had one gun on the forecastle, one on a platform between her funnels and the third aft of the superstructure. The destroyers were equipped with a pair of single rotating mounts for 21-inch (533 mm) torpedo tubes amidships and carried two reload torpedoes.
Construction and career
HMS Ardent, the seventh Royal Navy ship to bear the name, was ordered under the 1911–1912 Naval Programme from William Denny & Brothers. The ship was laid down at the company's Dumbarton shipyard on 9 October 1911, launched on 8 September 1912 and commissioned in February 1914. She joined the 4th Destroyer Flotilla on completion, and served with the Grand Fleet on the outbreak of the First World War.
