The boat was sunk by a German U-boat in 1917.

==Design and description== {{stack|thumb|HMS ''C34''}} 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|lk=on}} on the surface and {{convert|320|LT|t}} submerged. The C-class submarines had a crew of two officers and fourteen ratings.<ref name=gg9>Gardiner & Gray, p. 87</ref>

For surface running, the boats were powered by a single 12-cylinder<ref>Harrison, Chapter 25</ref> {{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.<ref name=gg9/> 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}}.<ref>Harrison, Chapters 3</ref>

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.<ref>Harrison, Chapter 27</ref>

==Construction and career== [[File:Memorial to Ingleby Stuart Jefferson in Ripon Cathedral.JPG|thumb|Memorial to Ingleby Stuart Jefferson in Ripon Cathedral]] HMS ''C34'' was built by HM Dockyard, Chatham for the Royal Navy. She was laid down on 29 March 1909 and was commissioned on 17 September 1910. The boat was sunk by the Imperial German Navy U-boat {{SMU|U-52||2}} off Fair Isle in Shetland while on the surface on 17 July 1917. The only survivor was picked up by ''U-52''.<ref>{{cite web |url=http://uboat.net/wwi/ships_hit/1019.html |title=C 34 |publisher=Uboat.net |accessdate=9 October 2012}}</ref>
