Design and description
L9 and its successors were enlarged to accommodate 21-inch (53.3 cm) torpedoes and more fuel. The submarine had a length of Script error: No such module "convert". overall, a beam of Script error: No such module "convert". and a mean draft of Script error: No such module "convert"..[1] They displaced Script error: No such module "convert". on the surface and Script error: No such module "convert". submerged. The L-class submarines had a crew of 35 officers and ratings.[2] They had a diving depth of Script error: No such module "convert"..[3]
For surface running, the boats were powered by two 12-cylinder Vickers[4] Script error: No such module "convert". diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a Script error: No such module "convert". electric motor.[1] They could reach Script error: No such module "convert". on the surface and Script error: No such module "convert". underwater. On the surface, the L class had a range of Script error: No such module "convert". at Script error: No such module "convert"..[3]
The boats were armed with four Script error: No such module "convert". torpedo tubes in the bow and two Script error: No such module "convert". tubes in broadside mounts. They carried four reload torpedoes for the 21-inch tubes for a grand total of ten torpedoes of all sizes.[5] They were also armed with a Script error: No such module "convert". deck gun.[2]
Construction and career
HMS L27 was built by Vickers at their Barrow-in-Furness shipyard, launched on 14 June 1919. She was then towed and completed at HM Dockyard, Sheerness and commissioned on an unknown date.
At the onset of the Second World War, L27 was a member of the 6th Submarine Flotilla. From 26–29 August 1939, the flotilla deployed to its war bases at Dundee and Blyth.[6] From 20 September 1939 to 15 January 1940, the 6th Submarine Flotilla was deployed off Skagerrak, Jutland and Horns Reef.[7] On 15 October 1940 L27 attacked a German convoy unsuccessfully in the English Channel.[8]
Beginning on 22 March 1941, the Royal Navy and Allies began deploying submarines off Brest, France to prevent the German battleships Script error: No such module "WPSHIPS utilities".Script error: No such module "Check for unknown parameters". and Script error: No such module "WPSHIPS utilities".Script error: No such module "Check for unknown parameters". from leaving port. L27 was among the submarines assigned to the patrol.[9] On 15 October 1941, the submarine unsuccessfully attacked a merchant vessel off Cherbourg.[10]
L27 was converted into a training boat at Portsmouth before being broken up in Canada in 1944.[11][note 1]
