See main article: S-class destroyer. Stronghold was one of thirty-three Admiralty destroyers ordered by the British Admiralty in June 1917 as part of the Twelfth War Construction Programme. The design was a development of the introduced as a cheaper and faster alternative to the . Differences with the R class were minor, such as having the searchlight moved aft.
Stronghold had a overall length of 276feet and a length of 265feet between perpendiculars. Beam was 26feet and draught 9feet. Displacement was 1075LT normal and 1221LT deep load. Three Yarrow boilers fed steam to two sets of Parsons 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. The ship carried 301LT of oil, which gave a design range of 2750nmi at . The ship had a complement of 90 officers and ratings.
Armament consisted of three QF 40NaN0 Mk IV guns on the ship's centreline. One was mounted raised on the forecastle, one between the funnels and one aft. The ship also mounted a single 401NaN1 2-pounder pom-pom anti-aircraft gun for air defence. Four 210NaN0 tubes were fitted in two twin rotating mounts aft. The ship was designed to mount two 180NaN0 tubes either side of the superstructure but this addition required the forecastle plating to be cut away, making the vessel very wet, so they were not fitted. The weight saved enabled the heavier Mark V 21-inch torpedo to be carried.
Laid down in March 1918 by Scotts Shipbuilding and Engineering Company in Greenock with the yard number 494, Stronghold was launched on 6 May 1919. The vessel was the first, and only, of the name. Completed on 2 July 1919, the ship served in active duty for only a few days, being reduced to the Reserve Fleet at Portsmouth on 10 July.[1] The vessel was recommissioned in Reserve at Portsmouth on 16 August 1920.[2]
Unlike many of the class which suffered deterioration over the ensuing years, Stronghold was drafted into service as part of Naval experiments with the Royal Navy's first experiments with guided missiles. In 1924, the destroyer was equipped with a simple catapult to launch the RAE 1921 Target unmanned vehicle. First used on 3 September, 1924, despite the flight lasting only twelve minutes, this was the first Remote Piloted Vehicle (RPV) flown. The Target was successfully launched twelve times in the following two years. The aircraft was initially accelerated to launch by the simple process of dropping a large bag of water off the side of the ship. This was replaced by a more sophisticated catapult powered by cordite in 1927. The new catapult was used to test the more capable RAE Larynx, the first success launch taking place in the Bristol Channel on 20 July 1927. At the second launch, on 1 September, the aircraft is believed to have flown, while the third and final flight, on 15 October, struck the ground from its target after travelling . The catapult was subsequently removed. In July 1931, Stronghold, in reserve at Portsmouth was recommissioned to replace as tender to the Torpedo School, with Taras crew transferring to Stronghold.[3] In 1938, Stronghold was equipped as a minelayer, capable of carrying thirty-eight mines as an alternative to the aft guns and torpedo tubes.
At the start of the Second World War, Stronghold was based in Singapore. On 10 December 1941, the destroyer was once again involved in supporting aircraft, this time a Supermarine Walrus from the battlecruiser . The flying boat had been launched prior to the Japanese aerial attack that had sunk the capital ship and had been flying since. Stronghold took the aircraft in tow back to Singapore, the ASV radar mounted in the Walrus proving a useful security against submarine attack. On 16 January 1942, the destroyer formed part of the Far Eastern Squadron, or China Force, led by the light cruisers, and . The force was allocated to escorting convoys. On 3 February, Stronghold was tasked with towing the Royal Australian Navy destroyer, which had been refitting in Singapore, on the first part of that vessel's journey to Fremantle.
Between 11 and 13 February, the destroyer helped escorting what has been termed the Empire Star Convoy, after the Blue Star Line refrigerated cargo ship Empire Star. Stronghold was then assigned to undertake an anti-submarine patrol off the coast of Cilacap. The ship sailed on 1 March, sweeping at . The destroyer spotted the Dutch evacuee ship Zandaam and provided essential cover against submarines until the heavily laiden vessel steamed off at speed to Fremantle. The destroyer itself then set off for Onslow, Western Australia. Unable to refuel at Cilacap, the destroyer was short of fuel and so had cruise at an economic speed of between .
The ship was sighted at about 09:00 on 2 March by a Japanese reconnaissance seaplane south of Bali. The seaplane reported the position of the British vessel to the Japanese fleet. As 17:05, the first shell splashes appeared to the starboard. By 17:43, the destroyer was being attacked by the heavy cruiser, which was being accompanied by and, escorted by the destroyers and . Maya opened fire at a range of with 8inches shells, the destroyers at with their 5inches guns. Stronghold returning fire soon after. Heavily outgunned, the destroyer sustained damage aft, in the forward mess and the engine room, which had to be abandoned. The Japanese destroyers then attacked with torpedoes, one of which crippled the ship. The crew abandoned ship and Stronghold sank at 19:00. The cruiser expended 635 rounds, Nowaki 345 rounds and Arashi 290 rounds in the sinking.
The crew had to rely on Carley floats as the ship's lifeboats had been destroyed in the action. The four floats separated and drifted in the open sea for three days. Fifty survivors were rescued by a Dutch steamer with a Japanese crew on 5 March, who were then transferred to a Japanese cruiser and interred as prisoners of war. In all, nine officers and sixty-one ratings were killed, with an additional two subsequently dying in the camp.
