HMS Swift was a unique destroyer leader designed and built for the Royal Navy prior to World War I, another product of Admiral "Jackie" Fisher''s relentless quest for speed. A specification for the design was produced by the Admiralty in December 1904, and the (subsequently successful) Cammell Laird design was evaluated against four others from Thornycrofts, Fairfields, John Brown and Armstrong Whitworth. She was designed to be the prototype for a class of large ocean-going destroyer, but no other leaders were built before the outbreak of war in 1914, and she remained something of an aberration; the only ship in the Royal Navy of this type, size and design.
