The boat survived the First World War and was sold for scrap in 1919.

==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.<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&nbsp;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== '''HMS ''C37''''' was built by Vickers, Barrow. She was laid down on 7 April 1909 and was commissioned on 31 March 1910. Along with her sisters {{HMS|C36||2}} and {{HMS|C38||2}}, ''C37'' was transferred to Hong Kong in February 1911 to operate with the Royal Navy's China Squadron. HMS ''C37'' was sold on 25 June 1919 in Hong Kong.
