Six Earnest-class destroyers served with the Royal Navy: Earnest, Griffon, Locust, Panther, Seal and Wolf. These ships were all built by Cammell Laird and were part of the class of 'thirty knotters'. Concern about the higher speeds of foreign boats had prompted to Admiralty to order new destroyers capable of , rather than the requirement which had been standard. The boats were not able to make this speed in bad weather, where they were usually wet and uncomfortable with cramped crew quarters, but they proved their toughness in serving through World War I, despite being twenty years old. Thanks to their watertight bulkheads, their thin plating and light structure they were able to take a great deal of damage and remain afloat, although their plates buckled easily, affecting their handling.
