HMS Cameleon was one of 20 Acorn-class destroyers built for the Royal Navy in the 1910s. Completed in 1910, she saw active service in the First World War.

The Acorn class marked a return to oil-firing as pioneered in the Tribal or F class of 1905 and HMS Swift of 1907. The Admiralty provided general specifications, but each shipyard did their own detailed design so that ships often varied in size.^[1] The Acorns had an overall length of 246 feet (75 m), a beam of 25 feet 5 inches (7.7 m), and a deep draught of 8 feet 6 inches (2.6 m). The ships displaced 772 long tons (784 t) at deep load and their crew numbered 72 officers and ratings.^[2]

The destroyers were powered by a single Parsons steam turbine that drove three propeller shafts using steam provided by four Yarrow boilers. The engines developed a total of 13,500 shaft horsepower (10,100 kW) and were designed for a speed of 27 knots (50 km/h; 31 mph). Cameleon reached a speed of 28.2 knots (52.2 km/h; 32.5 mph) from 14,790 shp (11,030 kW) during her sea trials.^[3] The Acorns 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).^[2]

The primary armament of the ships consisted of a pair of BL 4-inch (102 mm) MK VIII guns in single, unprotected pivot mounts fore and aft of the superstructure. They were also armed with two single QF 12-pounder (3-inch (76 mm)) guns, one on each broadside between the forward and centre funnels. These destroyers were equipped with a pair of single rotating mounts for 21-inch (533 mm) torpedo tubes amidships and carried two reload torpedoes.^[4]

Cameleon was ordered under the 1909–1910 Naval Programme from Fairfield Shipbuilding & Engineering Company. The ship was laid down at the company's Govan shipyard on 6 December 1909, launched on 2 June 1910 and commissioned in December. She was sold for scrap on 21 November 1921.^[5]
