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 238 feet 7 inches (72.7 m) overall, a beam of 23 feet 6 inches (7.2 m) and a mean draft of 13 feet 3 inches (4.0 m). [1] They displaced 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. [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 [4] 1,200- brake-horsepower (895 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 600-horsepower (447 kW) electric motor. [1] They could reach 17 knots (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 (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 in the bow and two 18-inch (45 cm) 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. [2]

Construction and career

HMS L24 was built by Vickers at their Barrow-in-Furness shipyard, launched on 19 February 1919, and completed at an unknown date. The boat was sunk with all hands lost in a collision with the battleship Resolution during an exercise off Portland Bill in the English Channel on 10 January 1924. [6] A memorial is located in St Ann's Church in HMNB Portsmouth. [7]

The wreck is located at 50°22.50′N02°37.79′W / 50.37500°N 2.62983°W / 50.37500; -2.62983 at a depth of 52 metres. Her hydroplanes remain set to hard dive, indicating that she was trying to take evasive action. A hatch is open and there is obvious damage where Resolution sliced into her hull. The wreck is designated as a protected place under the Protection of Military Remains Act 1986.
