British M-Class destroyer

|
HMS Orcadia was a Repeat Admiralty M-class destroyer that served in the Royal Navy during the First World War. The M class was an improvement on those of the preceding L class, capable of higher speed. Orcadia had a largely uneventful war. Joining the Fifteenth Destroyer Flotilla of the Grand Fleet in 1917, the ship was dispatched from the flotilla to the naval base Portsmouth. The vessel was a participant in anti-ship and anti-submarine patrols as part of the flotilla, but did not engage any enemy warships. The Admiralty increasingly used more successful convoys rather than relying on destroyers finding the enemy on patrol. After the Armistice that ended the war, Orcadia was allocated to the Local Defence Flotilla at Portsmouth and was sold in 1921 to be broken up.
Design and development
Orcadia was one of 16 Repeat Admiralty M-class destroyers ordered by the British Admiralty in February 1915 as part of the Fourth War Programme soon after the start of the First World War. The M class was an improved version of the earlier L class, required to reach a higher speed in order to counter rumoured new German fast destroyers. The remit was to have a maximum speed of 36 knots (67 km/h; 41 mph) and, although ultimately the destroyers fell short of that ambition in service, the extra performance that was achieved was valued by the navy. It transpired that the German warships did not exist. The Repeat M class differed from the prewar vessels in having a raked stem and minor design improvements based on wartime experience.
The destroyer had a length of 265 ft (80.8 m) between perpendiculars and 273 ft 4 in (83.3 m) overall, with a beam of 26 ft 8 in (8.1 m) and draught of 8 ft 11 in (2.7 m). Displacement was 948 long tons (963 t) normal. Power was provided by three Yarrow boilers feeding Brown-Curtiss steam turbines rated at 27,800 shaft horsepower (20,700 kW). The turbines drove three shafts and exhausted through three funnels. Design speed was 34 knots (63 km/h; 39 mph), which the vessel exceeded on trials. A total of 228 long tons (232 t) of oil was carried to give a design range of 2,530 nautical miles (4,690 km; 2,910 mi) at 15 knots (28 km/h; 17 mph). The ship had a complement of 80 officers and ratings.
Orcadia had a main armament consisting of three single QF 4-inch (102 mm) Mk IV guns on the centreline, with one on the forecastle, one aft on a raised platform and one between the middle and aft funnels. Torpedo armament consisted of two twin torpedo tubes for 21 in (533 mm) torpedoes located aft of the funnels. Two single 1-pounder 37 mm (1.5 in) "pom-pom" anti-aircraft guns were carried.
