s posed a threat to battleships: large numbers of torpedo boats could overwhelm a battleship's defences and sink it, or distract the battleship and make it vulnerable to opposing capital ships. Torpedo boats proved devastatingly effective in the 1891 Chilean Civil War. The defence against torpedo boats was clear: small warships accompanying the fleet that could screen and protect it from attack by torpedo boats. Several European navies developed vessels variously known as torpedo boat "catchers", "hunters" and "destroyers", while the Royal Navy itself operated

that was characteristic of early British TBDs. All six of them were removed from service and disposed of by the end of 1912, and thus were not affected by the Admiralty decision in 1913 to group all the surviving 27-knot and 30-knot destroyers (which had followed on these six 26-knot vessels) into four heterogeneous classes, labelled "A", "B", "C" and "D" classes. and were both built by

and three 6-pounder guns, with one fixed 18-in torpedo tube in the bow plus two more torpedo tubes on a revolving mount abaft the two funnels. Later the bow torpedo tube was removed and two more 6-pounder guns added instead. They produced from a pair of Thornycroft water-tube boilers, giving them a top speed of 27 knots. In common with subsequent early Thornycroft boats, they had sloping sterns and double rudders.
