Three Gipsy-class destroyers served with the Royal Navy; Osprey, Fairy and Gipsy were three funnelled C-class destroyers built by Fairfield with Thorneycroft boilers. Leven, Falcon and Ostrich are sometime referred to as the Falcon class but are here listed under the Gipsy class. These long ships were armed with the standard 12-pounder gun and two torpedo tubes and all served in the First World War in home waters.
