HMS Swift was a unique destroyer leader designed and built for the Royal Navy prior to World War I, yet another product of Admiral "Jackie" Fisher's relentless quest for speed. She was designed to be the prototype for a class of large ocean-going destroyers, but remained something of an abortion; the only ship in the Royal Navy of this type, size and design.

The tonnage of Swift was double that of her contemporary destroyers, in order to produce a vessel large enough and fast enough to take on the scouting duties of the cruiser. As such she was designed wih oil firing and four shafts to make 39 knots. It was released that she had met this on builder's trials, even though she failed to better 35 knots. This minor fallacy was somewhat irrelevant however, as even if she had made her design speed she carried only 180 tons of oil fuel and at full power was uneconomical. Her cruising radius at speed was therefore totally unsuitable for scouting duties. For a vessel of her size she was also lightly built and armed to reduce displacement, and was consequently a poor seaboat and of limited operational utility.

After operational damage in the Battle of Dover Strait in 1917 she was reconstructed, recieving a permanent bridge and wheelhouse structure and had the sided 4 inch guns on the forecastle replaced with a 6 inch weapon. As such she was the only Royal Navy destroyer to ever carry a gun of this caliber. Quietly sidelined and scrapped after the war, her size was not approached in the Royal Navy until the Tribal class of 1936.
