The '''Type 42''' or '''''Sheffield'' class''' was a class of fourteen [[guided-missile destroyer]]s that served in the [[Royal Navy]].<ref name=Marriott_1945_RN_DestroyerBook>Marriott, Leo: ''Royal Navy Destroyers since 1945'', {{ISBN|0-7110-1817-0}}, Ian Allan Ltd, 1989</ref> A further two ships of this class were built for and served with the [[Argentine Navy]].

The first ship of the class was ordered in 1968 and launched in 1971. Two of the class (''Sheffield'' and ''Coventry'') were lost to enemy action during the [[Falklands War]] of 1982. The Royal Navy used this class of destroyer for 38 years between 1975 and 2013.

No ships of this class remain active in the Royal Navy and both have also been retired from the Argentine Navy. The Royal Navy has replaced them with [[Type 45 destroyer]]s.

==History==
{{unreferenced section|date=October 2017}}
The class was designed in the late 1960s to provide fleet area air defence. In total fourteen vessels were constructed in three batches. In addition to the Royal Navy ships, two more ships were built to the same specifications as the Batch 1 vessels for the [[Navy of the Argentine Republic|Argentine Navy]]. ''Hércules'' was built in the UK and ''Santísima Trinidad'' in the AFNE Rio Santiago shipyard in Buenos Aires.

{{HMS|Sheffield|D80|2}} and {{HMS|Coventry|D118|2}} were lost in the [[Falklands War]] to enemy action. This was the first conflict where surface warships of the same design have been on opposite sides since [[World War II]], when four {{sclass2|Flower|corvette}}s built for France in 1939 were taken over by the ''[[Kriegsmarine]]'' in 1940. The final ship of the class (''Edinburgh'') decommissioned on 6 June 2013. One Argentine Navy ship ({{ship|ARA|Hércules|B-52|2}}) remains in service, the other vessel ({{ship|ARA|Santísima Trinidad|1974|2}}) sank whilst alongside in Puerto Belgrano Naval Base in early 2013.

When the [[Type 82 destroyer|Type 82]] air-defence destroyers were cancelled along with the proposed [[CVA-01]] carrier by the Labour Government of 1966, the Type 42 was proposed as a lighter and cheaper design with similar capabilities to the Type 82. The class is fitted with the GWS30 [[Sea Dart]] [[surface-to-air missile]] first deployed on the sole Type 82 destroyer, {{HMS|Bristol|D23|2}}. The Type 42s were also given a [[flight deck]] and hangar to operate an [[anti-submarine warfare]] helicopter, greatly increasing their utility compared to the Type 82, which was fitted with a flight deck but no organic aviation facilities.

The design was budgeted with a ceiling of £19 million per hull but soon ran over budget. The original proposed design (£21 million) was similar to the lengthened 'Batch 3' Type 42s. To cut costs, the first two batches had 47 feet removed from the bow sections forward of the bridge, and the beam-to-length ratio was proportionally reduced. These early, batch 1 Type 42s performed poorly during the contractor's sea trials, particularly in heavy seas, and the hull was examined for other problems. Batch 2 vessels (''Exeter'' onwards) embodied better sensor fits and slight layout modifications. The ninth hull, ''Manchester'', was lengthened in build, as part of a design review. This proved a better hull form at sea and later hulls were built to this specification. Strengthening girders were later designed into the weather deck structure in the batch 1 and 2 ships, and the batch 3 ships received an external '[[strake]]' to counter longitudinal cracking.

==Design==
The first batch had the [[Type 965 radar|965]] or 966 surveillance radar, which had a "slow data-rate".<ref name=PrestonFalklands112/> The Type 992Q radar used to designate targets for the gun and missiles lacked Moving Target Indiction (MTI). Though "British radar manufacturers [had] offered to retrofit MTI to these radars... nothing was done."<ref name=PrestonFalklands112/> Without MTI, the Type 992Q had difficulty in tracking aircraft when land was behind the aircraft or when there was snow or rain showers.<ref name=PrestonFalklands112/> The Type 42 also had "insufficient space for an efficient operations room".<ref name=PrestonFalklands112>A Preston. ''Sea Combat off the Falklands''. Willow Collins. (1982)London, pp. 112–113</ref>

The Type 42 was also equipped with a [[4.5 inch Mark 8 naval gun]] and earlier vessels had six Ships Torpedo Weapon System (STWS) [[torpedo]] launchers. Two [[Phalanx CIWS|Phalanx]] Mk&nbsp;15 [[close-in weapon system|close-in weapon systems (CIWS)]] were fitted to British Type 42s after the loss of ''Sheffield'' to an [[Exocet]] missile in 1982.

There have been three batches of ships, batch 1 and 2 displacing 4,820&nbsp;tonnes and batch 3 (sometimes referred to as the ''Manchester'' class) displacing 5,200&nbsp;tonnes. The batch 3 ships were heavily upgraded, though the proposed [[Sea Wolf (missile)|Sea Wolf]] systems upgrades were never fitted. Because of their more general warfare role, both Argentine ships were fitted with the MM38 Exocet, and not with a CIWS.

The electronics suite included one Type 1022 [[D band (NATO)|D band]] long-range radar with Outfit LFB track extractor or one [[Type 965 radar|Type 965P]] long-range air surveillance radar, one Type 996 [[E band (NATO)|E band]]/[[F band (NATO)|F band]] [[3D radar]] for target indication with Outfit LFA track extractor or type 992Q surface search, two Type 909 I/J-band [[fire-control radar]]s and an Outfit LFD radar track combiner.

All ships were propelled by [[Rolls-Royce Olympus|Rolls-Royce TM3B Olympus]] and [[Rolls-Royce Tyne|Rolls-Royce RM1C Tyne]] marinised gas turbines, arranged in a COGOG (combined gas or gas) arrangement, driving through synchronous self-shifting clutches into a double-reduction, dual tandem, articulated, locked-train gear system and out through two five-bladed <!--Stone Manganese refers to the company that built them, now called Stone Marine (http://www.stonemanganese.co.uk/)-->[[controllable pitch propellers]]. All have four [[Paxman Ventura]] 16YJCAZ [[diesel generator]]s, each generating 1 [[megawatt]] of [[three-phase electric power]] (440&nbsp;V 60&nbsp;Hz).

[[File:HMS Sheffield (D80).jpg|thumb|right|''Sheffield'' with the prominent exhaust deflectors on her funnel]]

The first of class, ''Sheffield'', was initially fitted with exhaust deflectors on her funnel tops to guide the high-temperature exhaust efflux sidewards and minimise damage to overhead aerials. As this provided a prominent target for then-new [[infrared homing]] missiles, only ''Sheffield'' and both the Argentinian ''Hércules'' and ''Santísima Trinidad'' had these. All subsequent engine uptakes were fitted with 'cheese graters' that mixed machinery space vent air with the engine exhaust to reduce [[infrared signature]]s.

==Availability and use of the Type 42==
{{unreferenced section|date=October 2017}}
This class was originally conceived to be a stopper for long-range [[strategic bomber]]s from the former Soviet [[Long-Range Aviation|Long Range Aviation]]/A-VMF and as area defence for carrier battle groups. Seven of the class took part in the [[Falklands War]] (Operation Corporate) and the immediate aftermath. The Type 42 provided a capable long-range defence against Argentine air force assets, scoring three confirmed kills. However, ''Sheffield'' was hit and disabled by a long-range first-generation air-to-surface missile ([[Exocet]]) and sank six days later, ''Coventry'' was sunk by conventional iron bombs, and ''Glasgow'' was disabled by a single bomb that passed straight through her aft engine room without exploding; an extensive rethink was conducted and future iterations were adopted. Later uses included The [[Gulf War]], when ''Gloucester'' shot down a land-based surface-to-surface missile. Type 42s were called upon to carry out fleet contingency ship duties such as [[West Indies]] counter drugs operations and Falkland Islands patrol, [[NATO]] Mediterranean and Atlantic task group operations, and [[Persian Gulf]] patrols. The deployment of [[Type 23 frigate|Type 23]]s in lieu of Type 42s to high-intensity mission areas became more prevalent as serviceability and reliability issues dogged Type 42s availability, as did obsolescence of their combat and machinery system equipment.

Owing to difficulties in recruiting labourer to work on construction the ship was only completed in 1978 and cost double the original price (over £30 million)."  On page 129 it gives the source of this cost data as: "''Fourth Report from the Committee on Public Accounts, 1976–77'' (H.C. 304), April 1977, pp xii–xiii and Q. 92."<br>The cost quoted in ''Aldrich'' is from a source written before the completion of the vessel, and so is less complete than the cost quoted in ''Jane's'' and ''Marriott'', which were written after completion of the vessel, and are nearly the same as the Hansard figure.</ref>

The surviving [[Argentina|Argentine]] Type 42, ''Hércules'', was based at [[Puerto Belgrano Naval Base]], Argentina, and converted into an amphibious command ship through the addition of a new aft superstructure and hangar. She was originally fitted with four single Exocet missile launchers, two on either side of the funnel facing forward but these were removed during refit. As of 2020, ''Hércules'' was reported to be non-operational.<ref name="zona-militar.com"/> The other Argentine vessel, ''Santísima Trinidad'', capsized and sank alongside her berth at Puerto Belgrano on 22 January 2013, reportedly as a result of poor maintenance and negligence leading to a burst seawater main and catastrophic flooding.<ref name="telegraph.co.uk">{{cite news |work=The Daily Telegraph |url=https://www.telegraph.co.uk/news/worldnews/southamerica/falklandislands/9820163/Falklands-warship-sinks-in-Argentina.html |title=Falklands warship sinks in Argentina |date=23 January 2013 |access-date=20 June 2015 |archive-url=https://web.archive.org/web/20150925232858/http://www.telegraph.co.uk/news/worldnews/southamerica/falklandislands/9820163/Falklands-warship-sinks-in-Argentina.html |archive-date=25 September 2015 |url-status=live }}</ref> She was formally taken out of service in 2024.<ref>{{cite web |url=https://www.zona-militar.com/en/2024/03/22/after-years-without-sailing-the-argentine-navy-confirms-the-definitive-decommissioning-of-the-multipurpose-fast-transport-ara-hercules/ |title=After years without sailing, the Argentine Navy confirms the definitive decommissioning of the Multipurpose Fast Transport ARA “Hércules” |last=Videla Solá |first=Mariano Germán |work=Zona Militar |date=22 March 2024 |access-date=27 March 2024 }}</ref>

Prior to her demise, ''Santísima Trinidad'' was extensively [[Cannibalization (parts)|cannibalised]] for spare parts for her more active sister ship. In December 2015, she was refloated and placed in drydock to evaluate the cost of restoration as a museum ship. Finally, due to the very high cost required, it was decided to scrap her in 2016.<ref name=":0" />

==Replacement==

The UK ships are all now decommissioned. By 2007 none of the batch 1 vessels remained in commission. Initially, the UK sought to procure replacements first in collaboration with seven other [[NATO]] nations under the [[NFR-90]] project and then with France and Italy through the [[Horizon CNGF]] programme. However, both these collaborative ventures failed and the UK decided to go it alone with a national project.<ref name="NAO report">{{cite journal |url=http://www.nao.org.uk/publications/0809/the_type_45_destroyer.aspx |title=Providing Anti Air Warfare Capability: the Type 45 destroyer |journal=National Audit Office |date=13 March 2009 |isbn=978-0-10-295468-5|archive-url=https://web.archive.org/web/20110805061334/http://www.nao.org.uk/publications/0809/the_type_45_destroyer.aspx |archive-date=5 August 2011 |url-status=live }}</ref>

The UK Type 42s are succeeded by six [[Type 45 destroyer]]s. {{HMS|Daring|D32|2}}, {{HMS|Dauntless|D33|2}}, {{HMS|Diamond|D34|2}}, {{HMS|Dragon|D35|2}}, {{HMS|Defender|D36|2}} and {{HMS|Duncan|D37|2}} are all in commission. The Type 42 class suffered from cramped accommodation, a problem for crew safety and comfort, and also when finding space for upgrades. The Type 45s are considerably larger, displacing 7,500&nbsp;tonnes, compared to the Type 42 displacement of 3,600&nbsp;tonnes.<ref name="NAO report"/>
