The Royal Navy's G-class of diesel/electric submarines were launched between 1914 and 1917, and intended for operations in the North Sea and German Bight in World War I against German U-boats. The design was based on the E-class, adopting the double hull concept, but in practice showed little improvement, the ships notoriously slow to dive.[1][2]

A total of 14 boats were built at four yards: G1 to G5 by Chatham Dockyard, G6 & G7 by Armstrong Whitworth, G8 to G13 by Vickers, and G14 by Scott's on the Clyde. G15 was ordered from Samuel White's yard at Cowes, Isle of Wight, but cancelled.[3] The class was distinguished by the 21-inch stern torpedo tube, an electric oven in the galley, and Fessenden Underwater Sound Telegraphy. The G-class had their bows raised during the war to increase buoyancy and improve seakeeping.
