HMS C31 was one of 38 C-class submarines built for the Royal Navy in the first decade of the 20th century. She struck a mine in 1915 and sank with the loss of all hands.
Design and description
The C-class boats of the 1907–08 and subsequent Naval Programmes were modified to improve their speed, both above and below the surface. The submarine had a length of {{convert|142|ft|3|in|m|1}} overall, a beam of {{convert|13|ft|7|in|m|1}} and a mean draft of {{convert|11|ft|6|in|m|1}}. They displaced {{convert|290|LT|t}} on the surface and {{convert|320|LT|t}} submerged. The C-class submarines had a crew of two officers and fourteen ratings.Gardiner & Gray, p. 87
For surface running, the boats were powered by a single 12-cylinderHarrison, Chapter 25 {{convert|600|bhp|lk=in|0|adj=on}} Vickers petrol engine that drove one propeller shaft. When submerged the propeller was driven by a {{convert|300|hp|0|adj=on}} electric motor. They could reach {{convert|13|kn|lk=in}} on the surface and {{convert|8|kn}} underwater. On the surface, the C class had a range of {{convert|910|nmi|lk=in}} at {{convert|12|kn}}.Harrison, Chapters 3
The boats were armed with two 18-inch (45 cm) torpedo tubes in the bow. They could carry a pair of reload torpedoes, but generally did not as they would have to remove an equal weight of fuel in compensation.Harrison, Chapter 27
