River-class destroyer (1903)

The River class, renamed the E class in 1913, was a group of 37 torpedo boat destroyers built for the Royal Navy in the first few years of the twentieth century, each to its builder's own design. The class put more weight on seakeeping and endurance than on top speed in good weather, with a raised forecastle in place of the turtleback, and was the first Royal Navy destroyer class named systematically, after British, Irish and Portuguese rivers. Yarrow built its own type of the class at Poplar, in London, with four funnels set in two pairs, and Navypedia lists three of those ships in the Usk group, with two vertical triple expansion engines, four Yarrow boilers and a coal bunker of 120 tons. Almost every ship of the class was coal fired and had triple expansion steam engines, four being powered by steam turbines. Seven were sunk in the First World War, and the 28 ships that survived the war were all sold and scrapped by late 1920.
