- Acasta class destroyer
The "Acasta" (in September 1913 redesignated the K class) was a class of twenty
destroyer s built for theRoyal Navy under the Naval Programme of 1911 - 1912 that saw service duringWorld War I . They were the last class of Royal Navy destroyers to have mixed names with no systematic theme (seenaming conventions for destroyers of the Royal Navy for more information.) The class saw extensive wartime service and seven were lost, including four at theBattle of Jutland .Design
The "Acastas" were larger and heavier armed than the preceding H and I classes ("Acorn" and "Acheron", respectively), displacing about 25 % more and with the mixed calibre armament replaced with a uniform fit of QF 4-inch guns, which the "Acastas" introduced. Previous 4-inch weapons had been of the breech-loading (BL) type. The guns were shipped one each on the
forecastle and either side abreast the after torpedo tube (or amidships before and after the tube in some ships.) All ships had three funnels, the foremost being tall and narrow, the second short and wide and the third level with the second but narrower. The foremost torpedo tube was sited between the second and third funnels, a distinctive feature of this class.There were twelve 'standard' vessels built to a common Admiralty design, and eight builder's specials that (except for "Garland") had a shorter, less beamy hull; five of the latter were from Thornycroft with 22,500 shp, one by Parsons that made 31 knots on trials, a seventh from Fairfields, and an eight by William Denny, Dumbarton.
ervice
At the outbreak of World War I until mid-1916, the "Acastas" were serving in the
Grand Fleet as the 4th Destroyer flotilla, with "Swift" as leader. By the time of Jutland the leader was the "Faulknor" class leader "Tipperary", with "Ardent", "Fortune", "Shark" and "Sparrowhawk" lost in the course of the battle and "Acasta" was so badly damaged that she had to be practically rebuilt. After Jutland the remainder of the flotilla moved to the Humber and then toPortsmouth by the end of 1916, before dispersing, some ships to the 6th Destroyer Flotilla and theDover Patrol and the remainder to Devonport. All survivors of the war were sold out of service for scrapping by 1921.hips
