HMS Doon was a Hawthorn Leslie type River-class destroyer ordered by the Royal Navy under the 1903 – 1904 Naval Estimates.

In July 1908 Doon entered refit and had a new propeller shaft fitted at Sheerness Dockyard, returning to the Channel Fleet destroyer Flotilla at the end of September.

[3] On the night of 2/3 March 1909, Doon, which had set off from Portland Harbour with the destroyer Fawn to escort the Royal yacht Alexandra from Dover to Calais, collided with the steam trawler Halcyon.

On 30 August 1912 the Admiralty directed all destroyer classes were to be designated by alpha characters starting with the letter 'A'.

After 30 September 1913, she was known as an E-class destroyer and had the letter ‘E’ painted on the hull below the bridge area and on either the fore or aft funnel.

She was straddled by three salvoes with one near miss by an 11-inch (280 mm) shell grazing the after edge of the foremost funnel, damaging a Berthon collapsible lifeboat, before going overboard and bursting on impact with the water.
