The S class were a class of 67 destroyers built from 1917 for the Royal Navy during the First World War. The design was based on the Admiralty modified R class and all ships had names beginning with S or T.
They were built in three discrete groups; the Admiralty S class comprised 55 vessels (excluding two that were cancelled) built in two batches that were ordered in May and June 1917 respectively, while seven vessels were built to a distinct design by Yarrow and five more to another distinct design by Thornycroft. All ships had two funnels, a long fo'c'sle and a tall bridge which, unusually, was located behind the break in the main deck. Most of these ships were commissioned after World War I, but only eleven survived to serve in World War II. The remainder were scrapped in the mid-to-late 1930s, in order to comply with the limit on total destroyer tonnage imposed by the London Naval Treaty of 1930.
24 vessels were ordered in April 1917.
33 vessels were ordered in June 1917.
These five vessels were built to Thornycroft's own design; they were slightly larger than the Admiralty design and had engines of 29,000 shp. The first two were ordered in April 1917 and the last three in June 1917.
These seven vessels were built to Yarrow's own design; they were slightly smaller than the Admiralty design and had engines of only 23,000 shp. All ordered in April 1917; the orders for Torch and Tomahawk replaced previous orders for two Admiralty W-class destroyers previously ordered from Yarrow in December 1916 (Wayfarer and Woodpecker). Their design was weakened in order to optimize speed, which explains the early disposal of these vessels.
Five of the above Admiralty S class were transferred to the Royal Australian Navy in June 1919. The ships were all commissioned on 27 January 1920 although they spent much of their careers in reserve. None of these ships served in World War II, having been scrapped in 1937.
