HMS Cameleon (1910)

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.

Design and description
The Acorn class marked a return to oil-firing as pioneered in the Tribal or F class of 1905 and HMS Swift (1907) of 1907. The Admiralty provided general specifications, but each shipyard did their own detailed design so that ships often varied in size. The Acorns had an overall length of 246 ft, a beam of 25 ft, and a deep draught of 8 ft. The ships displaced 772 LT at deep load and their crew numbered 72 officers and ratings.

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 13500 shp and were designed for a speed of 27 kn. Cameleon reached a speed of 28.2 kn from 14790 shp during her sea trials. The Acorns had a range of 1540 nmi at a cruising speed of 15 kn.

The primary armament of the ships consisted of a pair of BL 4 in 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 in) 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.

Construction and career
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.
