HMS G10 was a British G-class submarine built for the Royal Navy during World War I. Description The G-class submarines were designed by the Admiralty in response to a rumour that the Germans were building double-hulled submarines for overseas duties. The submarines had a length of overall, a beam of and a mean draft of . They displaced on the surface and submerged. The G-class submarines had a crew of 30 officers and ratings. They had a partial double hull. For surface running, the boats were powered by two Vickers two-stroke diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a electric motor. They could reach on the surface and underwater. On the surface, the G class had a range of at . The boats were intended to be armed with one 21-inch (53.3 cm) torpedo tube in the bow and two 18-inch (45 cm) torpedo tubes on the beam. This was revised, however, while they were under construction, the 21-inch tube was moved to the stern and two additional 18-inch tubes were added in the bow. They carried two 21-inch and eight 18-inch torpedoes. The G-class submarines were also armed with a single deck gun. Construction and career Like the rest of her class, G10s role was to patrol an area of the North Sea in search of German U-boats. While on exercises, the submarine collided with a merchant vessel resulting in the destruction of the bridge and the periscopes. On 3 June 1916, following the Battle of Jutland, HMS Titania instructed G10 to locate and sink floating remains of to prevent the capture of materials. The submarine survived the war, and was sold for scrap in 1923.
