**HMS *L19*** was a [L-class](/source/British_L-class_submarine) [submarine](/source/Submarine) built for the [Royal Navy](/source/Royal_Navy) during [World War I](/source/World_War_I). The boat was not completed before the end of the war and was sold for [scrap](/source/Ship_breaking) in 1937.

## Design and description

*L9* and its successors were enlarged to accommodate [21-inch (53.3 cm)](/source/British_21-inch_torpedo) torpedoes and more fuel. The submarine had a length of 238 feet 7 inches (72.7 m) [overall](/source/Length_overall), a [beam](/source/Beam_(nautical)) of 23 feet 6 inches (7.2 m) and a mean [draft](/source/Draft_(ship)) of 13 feet 3 inches (4.0 m).[1] They [displaced](/source/Displacement_(ship)) 914 long tons (929 t) on the surface and 1,089 long tons (1,106 t) submerged. The L-class submarines had a crew of 38 officers and [ratings](/source/Naval_rating).[2] They had a diving depth of 150 feet (45.7 m).[3]

For surface running, the boats were powered by two 12-cylinder [Vickers](/source/Vickers)[4] 1,200-[brake-horsepower](/source/Horsepower#Brake_horsepower) (895 kW) [diesel engines](/source/Diesel_engine), each driving one [propeller shaft](/source/Propeller_shaft). When submerged each propeller was driven by a 600-horsepower (447 kW) [electric motor](/source/Electric_motor).[1] They could reach 17 [knots](/source/Knot_(unit)) (31 km/h; 20 mph) on the surface and 10.5 knots (19.4 km/h; 12.1 mph) underwater. On the surface, the L class had a range of 3,800 [nautical miles](/source/Nautical_mile) (7,000 km; 4,400 mi) at 10 knots (19 km/h; 12 mph).[3]

The boats were armed with four 21-inch [torpedo tubes](/source/Torpedo_tube) in the bow and two [18-inch (45 cm)](/source/British_18-inch_torpedo) 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 4-inch (102 mm) [deck gun](/source/Deck_gun).[2]

## Construction and career

HMS *L19* was [laid down](/source/Laid_down) on 18 July 1917 by [Vickers](/source/Vickers) at their [Barrow-in-Furness](/source/Barrow-in-Furness) [shipyard](/source/Shipyard), [launched](/source/Ship_naming_and_launching) on 4 February 1919, and completed on 2 August 1919. *L19* was assigned to the [4th Submarine Flotilla](https://en.wikipedia.org/w/index.php?title=4th_Submarine_Flotilla&action=edit&redlink=1) and [HMS Titania](/source/HMS_Titania) in 1919 and sailed to [Hong Kong](/source/Hong_Kong), arriving on 14 April 1920. *L19* was sold for scrap on 12 April 1937 at [Pembroke Dock](/source/Pembroke_Dock).
