HMS L52 was a late-model L-class submarine built for the Royal Navy during the First World War. The boat was not completed before the end of the war and was sold for scrap in 1935.
Design and description
L52 and its successors were modified to maximise the number of 21-inch (53.3 cm) torpedoes carried in the bow. The submarine had a length of {{convert|235|ft|m|1}} overall, a beam of {{convert|23|ft|6|in|m|1}} and a mean draft of {{convert|13|ft|2|in|m|1}}.Gardiner & Gray, p. 94 They displaced {{convert|960|LT|t}} on the surface and {{convert|1150|LT|t}} submerged. The L-class submarines had a crew of 44 officers and ratings.Akermann, p. 165 They had a diving depth of {{convert|150|ft|1}}.Harrison, Chapter 11
For surface running, the boats were powered by two 12-cylinder VickersHarrison, Chapter 25 {{convert|1200|bhp|lk=in|0|adj=on}} diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a {{convert|600|hp|0|adj=on}} electric motor. They could reach {{convert|17|kn|lk=in}} on the surface and {{convert|10.5|kn}} underwater. On the surface, the L class had a range of {{convert|4200|nmi|lk=in}} at {{convert|10|kn}}.
The boats were armed with six 21-inch torpedo tubes in the bow. They carried eight reload torpedoes for a grand total of a dozen torpedoes.Harrison, Chapter 27 They were also armed with two {{convert|4|in|mm|adj=on|0}} deck guns.
Construction and career
HMS L52 was laid down on 16 May 1917 by Armstrong Whitworth at their Newcastle-Upon-Tyne shipyard, launched on 18 December 1918, and completed on 18 January 1921. The boat was sold for scrap in September 1935, but was wrecked off Barry, South Wales.
