See main article: S-class destroyer. Saladin was one of 33 Admiralty destroyers ordered by the British Admiralty on 7 April 1917 as part of the Eleventh War Construction Programme. The design was a development of the introduced at the same time as, and as a cheaper and faster alternative to, the . Differences with the R class were minor, such as having the searchlight moved aft and being designed to mount an additional pair of torpedo tubes.
The destroyer had a overall length of 276feet and a length of 265feet between perpendiculars. Beam was 26feet and mean draught 9feet. Displacement was 1075LT normal and 1221LT deep load. Three Yarrow boilers fed steam to two sets of Brown-Curtis geared steam turbines rated at 27000shp and driving two shafts, giving a design speed of 36kn at normal loading and at deep load. Two funnels were fitted. A full load of of fuel oil was carried, which gave a design range of 2750nmi at .
Armament consisted of three QF 40NaN0 Mk IV guns on the ship's centreline. One was mounted raised on the forecastle, one on a platform between the funnels, and one aft. The ship also mounted a single 2-pounder 40mm "pom-pom" anti-aircraft gun for air defence. Four 21inches torpedo tubes were carried in two twin rotating mounts aft. Four depth charge chutes were also fitted aft. Initially, typically ten depth charges were carried. The ship was designed to mount two additional 180NaN0 torpedo tubes either side of the superstructure but this required the forecastle plating to be cut away, causing excess water to come aboard at sea, so they were removed. The weight saved enabled the heavier Mark V 21-inch torpedo to be carried. Fire control included a training-only director, single Dumaresq and a Vickers range clock. The ship had a complement of 90 officers and ratings.
Laid down on 10 September 1917 during the First World War by Alexander Stephen and Sons at their dockyard in Linthouse, Glasgow, Saladin was launched on 17 February 1919 after the Armistice that ended the war and completed on 11 April. The vessel was the only one in Royal Navy service named for Saladin, the founder of the Ayyubid dynasty, conqueror of Jerusalem and opponent of Richard I in the Third Crusade. Saladin was commissioned into the Reserve Fleet in Portsmouth on 18 August 1920.[1] The following few years were generally uneventful, the vessel serving as the emergency destroyer at Plymouth for much of the period.[2] On 19 June 1933, the destroyer formed part of the escort for King Faisal on a state visit.[3] On 17 September, the vessel took part in a water carnival in Brighton, the ship's searchlight adding to fireworks and other displays that celebrated the collaboration between the town and the city of Bristol.[4] On 16 July 1935, the destroyer was one of over 100 ships of the Royal Navy in a fleet review to celebrate the Silver Jubilee of George V.[5] Saladin was relieved as emergency destroyer by the newer W-class destroyer on 1 October and became an independent operator under the retired first rate ship of the line at Plymouth.[6] [7]
At the start of the Second World War, Saladin was in reserve at Portsmouth.[8] It was intended that the warship would be sent to join the Eastern Fleet, but this was delayed by a boiler retubing. Instead, the destroyer was upgraded as an escort to join the Sixteenth Destroyer Flotilla. The aft gun and torpedo tubes were removed and a high-angle QF 12-pounder anti-aircraft gun was fitted on a bandstand abaft the middle funnel. Two quadruple Vickers .50 machine guns were also mounted for close-in defence. ASDIC was installed along with eight depth charge throwers and new depth charge rails aft. A total of 112 depth charges were now carried. On 28 and 29 May 1940, while assisting in the Dunkirk evacuation of 47,310 British troops as part of Operation Dynamo, Saladin was attacked ten times by the German Luftwaffe, receiving multiple hits but none that put the ship out of action. Nonetheless, the ship's engine room was so severely damaged that the vessel had to sail back to Dover at and could take no part in the evacuation. The destroyer was swiftly repaired ready to return to service. On 9 June, the ship was dispatched as part of the escort for a flotilla of ships sent to evacuate soldiers from Le Havre. Despite bombing from the Luftwaffe, 11,059 British troops were rescued by the flotilla on 11 June. The following day, the destroyer arrived in St Valery, and evacuated an additional 15 sailors.
For the majority of the war, Saladin acted as a convoy escort. Between May 1940 and May 1944, the destroyer accompanied 76 convoys, including nine travelling from Halifax, Nova Scotia to Liverpool.[9] Between 11 and 15 September 1941, the destroyer formed part of the Second Escort Group that accompanied Convoy SC 42. Apart from the loss of one merchant ship, the escorts managed to prevent successful attacks from German submarines, including and during the following night, and sank .[10] Saladin remained part of the escort group for the remainder of the year, accompanying the Atlantic convoys ON 18 on 21 September, ON 25 on 13 October and HX 154 on 19 October. The following year saw the destroyer join the Seventh Escort Group, escorting the arctic convoy Convoy PQ 13 between 11 and 16 March. The passage was uneventful. During this time, the destroyer was upgraded again. The 12-pounder was removed and a Type 271 radar fitted instead while two single Oerlikon 20 mm cannon replaced the Vickers machine guns. These changes also increased the ship's displacement, which nearly reached .
In January 1944, Saladin was transferred to Plymouth to serve in the English Channel. On 25 March 1944, Saladin rescued seven survivors from a Short Sunderland flying boat that had been shot down over the Bay of Biscay on 23 March. On 28 April, the destroyer helped rescue survivors from and, sunk by German E-boats during Exercise Tiger, a rehearsal of the Normandy landings. Nonetheless, between 639 and 749 US Army soldiers and US Navy sailors lost their lives in the exercise. Saladin had been dispatched to escort the convoy but a problem with number one boiler meant that the vessel was only able to make and did not arrive in time for the action. The destroyer subsequently formed part of the escort for the Normandy landings. In December, the vessel was placed into reserve at Falmouth. With the demobilisation of the British Armed Forces after the Second World War, Saladin was decommissioned from service. On 29 June 1947, the ship was retired and handed over to be broken up by Rees at Llanelly.
