'''HMS ''Fermoy''''' was a [[Hunt-class minesweeper (1916)|Hunt-class]] [[minesweeper]] of the ''Aberdare'' [[ship class|sub-class]] built for the [[Royal Navy]] during [[World War I]]. She was not finished in time to participate in the First World War, and was crippled by German bombers in 1941 and later scrapped.

==Design and description==
The ''Aberdare'' sub-class were enlarged versions of the original Hunt-class ships with a more powerful armament. The ships displaced {{convert|800|LT|t}} at normal load. They had a [[length between perpendiculars]] of {{convert|220|ft|m|1}}<ref name=c6/> and measured {{convert|231|ft|m|1}} [[length overall|long overall]]. The ''Aberdare''s had a [[beam (nautical)|beam]] of {{convert|26|ft|6|in|m|1}} and a [[draft (hull)|draught]] of {{convert|7|ft|6|in|m|1}}. The ships' complement consisted of 74 officers and [[naval rating|ratings]].<ref name=l3>Gardiner & Gray, p. 98</ref>

The ships had two [[Marine steam engine#Triple or multiple expansion|vertical triple-expansion steam engines]], each driving one shaft, using steam provided by two [[Yarrow boiler]]s. The engines produced a total of {{convert|2200|ihp|lk=in}} and gave a maximum speed of {{convert|16|kn|lk=in}}. They carried a maximum of {{convert|185|LT|t|0}} of coal<ref name=l3/> which gave them a range of {{convert|1500|nmi|lk=in}} at {{convert|15|kn}}.<ref name=c6>Cocker, p. 76</ref>

The ''Aberdare'' sub-class was armed with a [[quick-firing gun|quick-firing (QF)]] {{Convert|4|in|mm|adj=on|0|spell=in}} gun forward of the [[bridge (nautical)|bridge]] and a QF twelve-pounder (76.2&nbsp;mm) [[anti-aircraft gun]] aft.<ref name=l3/> Some ships were fitted with six- or three-pounder guns in lieu of the twelve-pounder.<ref name=c6/>

==Construction and career==
HMS ''Fermoy'' was built by the [[Dundee Shipbuilding Company]]. By 1923 she had become the depot ship for the Submarine Periscope School at Portland and on 14 April [[Hugh Marrack]] was appointed in command.<ref>{{cite web |url=http://rnsubs.co.uk/crew/biographies/marrack.html |title=Hugh Richard Marrack: A short biography |last=Downer |first=Barrie |date=1997 |website=rnsubs.co.uk |access-date=27 September 2022 |archive-date=25 January 2022 |archive-url=https://web.archive.org/web/20220125162622/http://rnsubs.co.uk/crew/biographies/marrack.html |url-status=dead }}</ref>

She was bombed by Italian aircraft off [[Valletta]], [[Malta]], on 30 April 1941, then on 4 May 1941, and was written off as constructive total loss.  She was eventually raised and sold for scrap.
