 These vessels saw comparatively little action, most being completed in the closing stages or after the end of the First World War, and scrapped before the start of Second World War.The first S-class destroyer to be completed, "Simoom", joined the Grand Fleet in April 1918.The Commodore(F) commanding the Grand Fleet destroyer flotillas did not approve of the design, largely because of the 18-inch torpedoes, which were considered useless.
