'''His Majesty's Naval Base, Devonport''' ('''HMNB Devonport''') is one of three operating bases in the United Kingdom for the [[Royal Navy]] (the others being [[HMNB Clyde]] and [[HMNB Portsmouth]]) and is the sole nuclear repair and refuelling facility for the Royal Navy. The largest [[naval base]] in [[Western Europe]],<ref name=hmnbdevonport2023>{{cite web|url=https://www.royalnavy.mod.uk/our-organisation/bases-and-stations/naval-base/devonport |title=HMNB Devonport}}</ref> HMNB Devonport is located in [[Devonport, Devon|Devonport]], in the west of the city of [[Plymouth]], England.

The base began as a [[Royal Navy Dockyard]] in the late 17th century, designed and built on open ground by [[Edmund Dummer (naval engineer)|Edmund Dummer]] as an integrated facility for the repair and maintenance of warships, centred on his pioneering stone [[dry dock]] (one of the earliest stepped docks in the world).<ref name="1DockListing" /> Over the next two centuries it expanded, reaching its present extent in the 20th century.<ref name="20cNavalDockyards2" /> Historically, the yard was also used for shipbuilding: over 300 naval vessels were built there, the last being [[HMS Scylla (F71)|HMS ''Scylla'']] (launched in 1968).<ref>{{cite news|url=http://news.bbc.co.uk/local/devon/hi/people_and_places/history/newsid_8278000/8278316.stm|title=BBC – Plymouth's proud naval history|date=28 September 2009 |access-date=19 March 2016}}</ref> 

The yard was known as '''HM Dockyard, Plymouth''' until 1843, when it was renamed '''HM Dockyard, Devonport'''. (In the late 20th century, here as elsewhere, the term 'Naval Base' replaced 'Dockyard' in the official naval designation.)<ref name="20cNavalDockyards1">{{cite book |editor1-last=Coats |editor1-first=Ann |editor2-last=Davies |editor2-first=David |title=20th Century Naval Dockyards: Devonport and Portsmouth Characterisation Report - Part 1 |date=2013 |publisher=Naval Dockyards Society |location=Portsmouth, Hants. |url=https://historicengland.org.uk/images-books/publications/twentieth-century-naval-dockyards-devonport-portsmouth-characterisation-report/part1-twentieth-century-naval-dockyards-devonport-portsmouth-characterisation |access-date=15 August 2023}}</ref> 

Today HMNB Devonport serves as the home port of the '''Devonport Flotilla'''. [[Flag Officer Sea Training (United Kingdom)|FOST]], the training hub of the front-line Fleet, is also based there, as is the Royal Navy's Amphibious Centre of Excellence (at [[RM Tamar]]).<ref name="hmnbdevonport2023" /> Although shipbuilding ceased at Devonport in the late 1960s, ship repair and maintenance work has continued; the now [[Privatization|privatised]] maintenance facilities are operated under the name '''Devonport Royal Dockyard''' by [[Babcock International Group]], who took over the previous owner [[Devonport Management Limited]] (DML) in 2007 (DML had been running the Dockyard since privatisation in 1987).<ref name="HE" /> Babcock owns around a third of the overall area of the base (having been sold the freehold in 2011).<ref name="20cNavalDockyards2">{{cite book |editor1-last=Coats |editor1-first=Ann |editor2-last=Davies |editor2-first=David |title=20th Century Naval Dockyards: Devonport and Portsmouth Characterisation Report - Part 2 |date=2013 |publisher=Naval Dockyards Society |location=Portsmouth, Hants. |url=https://historicengland.org.uk/images-books/publications/twentieth-century-naval-dockyards-devonport-portsmouth-characterisation-report/part2-twentieth-century-naval-dockyards-devonport-portsmouth-characterisation |access-date=15 August 2023}}</ref>

Accommodation and support services are provided within the base for naval personnel. The Royal Naval Barracks, dating from 1889, were first commissioned as [[HMS Vivid|HMS ''Vivid'']], before being renamed [[HMS Drake|HMS ''Drake'']] in 1934. Since the early 21st century the name '''HMS ''Drake''''' (and its [[command structure]]) has been extended to cover the entire Naval Base,<ref name=hmnbdevonport2007>{{cite web|url=http://www.royalnavy.mod.uk/server/show/nav.3109 |title=HMNB Devonport |url-status=dead |archive-url=https://web.archive.org/web/20070108135602/http://www.royalnavy.mod.uk/server/show/nav.3109 |archive-date=8 January 2007 }}</ref><ref name="Handbook2010" /><ref>{{cite news |title=Gun salute tribute for Queen in Plymouth |work=BBC News |date=9 September 2022 |url=https://www.bbc.com/news/uk-england-devon-62851864 |access-date=14 March 2023}}</ref> while HMS ''Vivid'' is Plymouth's [[Royal Naval Reserve]] unit (which has its headquarters within the base).<ref name="HMSVividRNR" />

==The Naval Base today==

The Naval Base as a whole covers an area of {{convert|650|acre|km2}} with four miles (6&nbsp;km) of waterfront; it has twenty-five tidal berths, five [[Basin (maritime)|basins]] and fourteen dry docks (docks numbered 1 to 15, [[Triskaidekaphobia|but there is no 13 Dock]]). The base employs 2,500 service personnel and civilians, supports circa 400 local firms and contributes approximately 10% to the income of Plymouth.<ref name="hmnbdevonport2023" /> The Naval Base commander has in recent years been a [[Commodore (Royal Navy)|Commodore (RN)]], but in 2022 Brigadier Mike Tanner took command (the first [[Royal Marine]] officer to be appointed to the role).<ref>{{cite news |last1=Telford |first1=William |title=Ex-England rugby star named new Devonport Naval Base commander |url=https://www.plymouthherald.co.uk/news/plymouth-news/ex-england-rugby-star-named-7334634 |access-date=16 August 2023 |work=Plymouth Live |date=15 July 2022}}</ref>

===Devonport Flotilla===
In 2009 the [[Ministry of Defence (United Kingdom)|Ministry of Defence]] announced the conclusion of a long-running review of the long-term role of three naval bases. It was decided that Devonport would no longer be used as a base for attack submarines (these were subsequently moved to [[Faslane Naval Base|Faslane]]), and that the [[Type 45 destroyers]] would be based at Portsmouth; however, Devonport retains a long-term role as the dedicated home of the amphibious fleet, survey vessels and more than half the frigate fleet<ref>{{cite web|url=https://publications.parliament.uk/pa/cm201415/cmhansrd/cm150223/debtext/150223-0001.htm|title=Daily Hansard - Debate|publisher=UK Parliament House of Commons|date=2015-02-23}}</ref> (as well as [[HMS Triumph (S93)|HMS ''Triumph'']], the only remaining {{sclass|Trafalgar|submarine|0}} nuclear-powered hunter-killer submarine). In 2018 the [[Secretary of State for Defence|Defence Secretary]] announced that the proposed new [[Type 26 frigate]]s would all be based at Devonport.<ref>{{cite web |title=All Type 26 Frigates To Be Based At Devonport |url=https://www.forces.net/news/every-type-26-frigate-be-based-devonport |website=Forces Network |date=8 October 2018 |access-date=5 February 2019}}</ref> 

Ships based at the port are known as the Devonport Flotilla; they include:

In changes to base porting arrangements announced in November 2017, HM Ships ''Argyll'', ''Monmouth'' and ''Montrose'' were all to join the [[Portsmouth Flotilla]] (however, ''Monmouth'' retired in 2021, ''Montrose'' decommissioned in 2023 and ''Argyll'' in 2024); HM Ships ''Richmond'', {{HMS|Kent|F78|2}} and ''St Albans'' moved in the opposite direction, to Devonport. ''Richmond'' also became a Devonport ship on completion of her refit. ''St Albans'' moved to Devonport in July 2019 in preparation for her major refit.<ref>{{cite web|url=https://www.royalnavy.mod.uk/news-and-latest-activity/news/2017/november/24/171124-defence-secretary-announces-type-23-base-port-moves|title=Defence Secretary announces Type 23 base port moves|website=royalnavy.mod.uk}}</ref> HMS ''Westminster'' retired in 2024.

Babcock's privatised ''Devonport Royal Dockyard'' facility is co-located with HM Naval Base Devonport, providing 'through-life support for submarines, surface ships and associated systems and equipment'.<ref name="BabcockNBM">{{cite web |title=Naval Base Management |url=https://www.babcockinternational.com/what-we-do/support/frontline-support/naval-base-management/ |website=Babcock |access-date=16 August 2023}}</ref> Operational vessels are provided with 'in-service engineering maintenance support' from the yard, dry docks are available to 'maintain, refit, convert and modernise sophisticated modern surface warships' and specialised workshops enable complex systems to be 'removed, overhauled, tested and installed'.<ref name="BabcockNBM" /> 

In the early 1970s it was announced that Devonport would join [[Chatham Dockyard|Chatham]] and [[Rosyth Dockyard|Rosyth]] in serving as a refit base for [[nuclear submarines]]; the Submarine Refit Centre duly opened in 1981.<ref name="20cNavalDockyards2" /> Since 2002, Devonport has been the sole refitting base for all Royal Navy nuclear submarines.<ref>{{cite news|url=https://rina.org.uk/industry-news/naval-and-patrol/babcock-awarded-contract-to-refit-uk-nuclear-submarine/|title=Babcock awarded contract to refit UK nuclear submarine|publisher=Institute of Naval Architects|date=5 March 2024 |access-date=31 August 2024}}</ref>

Several sections of the South Yard (the oldest part of the Naval Base) are no longer used by the Ministry of Defence. Its historic [[Slipway|slips]] were formerly the shipbuilding centre of the Royal Dockyard. In 2012 the southernmost part of the site was sold to a private company and in 2014 the northernmost section was leased to [[Plymouth City Council]] as part of a [[City Deal]] regeneration project; other areas are leased to Babcock. In 2022 the whole of the South Yard (except for the north-east corner of the site) became part of Plymouth's [[Free ports in the United Kingdom|Freeport]].<ref name="PSDFMap" />

==History==
===Overview===
[[Image:Devonport Dockyard in 1909 plan.png|thumb|A 1909 map of HM Dockyard, Devonport, also showing the [[Board of Ordnance#Distribution points: the Royal Dockyards|Gun Wharf]] (Morice Yard) located between the South Yard and the North Yard]]

From its original 17th-century site, around No.1 Dock in what is now called the South Yard, the dockyard expanded in stages (first to the south and then progressively northwards) over the next two-and-a-half centuries. Key periods in the geographical development of the yard included:<ref name="Coad2013" />
*The building of Plymouth Dock and Yard (1692-1698).
*The building of Morice Ordnance Yard (1719-1720) alongside the dockyard to the north (this became part of the dockyard during the Second World War).
*The Great Rebuilding (1760-1790) which saw the dockyard expand to the south.
*The building of Keyham Steam Yard (1844-1865) to the north of the Morice Yard.
*The building of the Keyham Extension (1896-1907) which more than doubled the size of the Keyham yard.<ref name="20cNavalDockyards1" />
*Post-war appropriation of adjacent land (1950s) with bomb-damaged streets were brought within the dockyard perimeter to allow for future expansion.
*The reclamation of Weston Mill Lake (1972-1979), now the northernmost part of the base.<ref name="20cNavalDockyards2" />

===Origins===
[[File:Docks de Plymouth - btv1b53010267w (2 of 5).jpg|thumb|left|A 1689 proposal by Edmund Dummer for a single cruiser dock at Point Froward (the future site of the dockyard)]]

In 1689 Prince William of Orange became [[William III of England|William III]] and almost immediately he required the building of a new [[dry dock]] west of Portsmouth, 'for cruisers only' (to support the [[Cruiser#Early history|cruiser squadrons]] that patrolled the western approaches to the [[English Channel]]).<ref name="Coad1989">{{cite book |last1=Coad |first1=Jonathan G. |title=The Royal Dockyards1690-1850 |date=1989 |publisher=Scolar Press |location=Aldershot, Hants.}}</ref> [[Edmund Dummer (naval engineer)|Edmund Dummer]], [[Surveyor of the Navy]], travelled the West Country searching for an area where the dock could be built. Once he had settled on Plymouth, it took the rest of the year for the Admiralty to decide between two possible locations; eventually, in preference to [[Cattewater]], they settled on a site on the [[Hamoaze]] (a section of the [[River Tamar]]) in the parish of [[Stoke Damerel]]. On 30 December 1690, a contract was let for a dock to be built; having selected the location, Dummer was given responsibility for designing and building it.<ref name=wessom>{{cite web|first=William |last=Wessom |title=The Devonport Royal dockyard |url=http://www.freewebs.com/10yearsofism/THE%20PORT%20OF%20PLYMOUTH.doc |date=24 September 2007 |access-date=4 October 2009 |url-status=dead |archive-url=https://web.archive.org/web/20121022125510/http://www.freewebs.com/10yearsofism/THE%20PORT%20OF%20PLYMOUTH.doc |archive-date=22 October 2012 }}</ref>

Then the project began to grow: first the King requested a larger dock (suitable for [[first-rate]] ships, as well as cruisers), then the Navy required a [[Basin (maritime)|basin]] to protect the dock entrance; and finally, in July 1692, the Admiralty resolved that 'where the new dock is now building' a full [[Royal Navy Dockyard]] should be established, with 'buildings erected therein as well for the accommodation of the officers of the Navy that shall be appointed there, as for storehouses and other services'.<ref name="Coad1989" /> This was the start of Plymouth (later Devonport) Royal Dockyard.<ref name=wessom/>

At the heart of his new dockyard, Dummer placed a stone-lined [[wet dock]], giving access to what proved to be the first successful stepped stone [[Drydock|dry dock]] in Europe.<ref name = "Fox26">{{cite web |first=Celina |last=Fox |title=The Ingenious Mr Dummer: Rationalizing the Royal Navy in Late Seventeenth-Century England |url=http://www.bl.uk/eblj/2007articles/pdf/ebljarticle102007.pdf |work=Electronic British Library Journal |page=26 |year=2007 |access-date=6 October 2009 |archive-date=27 September 2013 |archive-url=https://web.archive.org/web/20130927054739/http://www.bl.uk/eblj/2007articles/pdf/ebljarticle102007.pdf |url-status=dead }}</ref> Previously the Navy Board had relied upon timber as the major building material for dry docks, which resulted in high maintenance costs and was also a fire risk. The docks Dummer designed were stronger with more secure foundations and stepped sides that made it easier for men to work beneath the hull of a docked vessel. These innovations also allowed rapid erection of staging and greater workforce mobility. He discarded the earlier three-sectioned hinged gate, which was labour-intensive in operation, and replaced it with the simpler and more mobile two-sectioned gate.<ref>{{cite web  |last=Fox  |title=The Ingenious Mr Dummer  |url=http://www.bl.uk/eblj/2007articles/pdf/ebljarticle102007.pdf  |page=27  |access-date=29 September 2009  |archive-date=27 September 2013  |archive-url=https://web.archive.org/web/20130927054739/http://www.bl.uk/eblj/2007articles/pdf/ebljarticle102007.pdf  |url-status=dead  }}</ref>

Dummer wished to ensure that naval dockyards were efficient working units that maximised available space, as evidenced by the simplicity of his design layout at Plymouth Dock. He introduced a centralised storage area (the quadrangular Great Storehouse) alongside the basin, and a logical positioning of other buildings around the yard. The southern boundary of his yard was formed by a 'double' [[Ropewalk|rope-house]] (combining the previously separate tasks of spinning and laying within a single building); the upper floor was used for the repair of sails and a separate rigging house stood nearby. The anchor [[smithery]] with its fire and forge was positioned to the north, safely separate from the other buildings. On high ground overlooking the rest of the yard he built a grand terrace of thirteen three-storey houses for the senior dockyard officers (the first known example in the country of a [[Terraced house#United Kingdom and Ireland|palace-front terrace]]); the commissioner was accommodated in the centre, and at each end of the terrace was a two-storey block of offices (one for the commissioner, the other for the Clerk of the Cheque).<ref name=Terrace>{{NHLE|desc=Listed building text|num=1378525|access-date=13 August 2015}}</ref> Work on the dockyard was completed by 1698.<ref name="Coad1989" /> Two years later a chapel was built, alongside the Porter's Lodge at the main gate<ref name="PicPlymouth1812">{{cite book |title=The Picture of Plymouth |date=1812 |publisher=Rees & Curtis |location=London |pages=102–115}}</ref> (it was destroyed by a fire in 1799).<ref name="SciMus">{{cite web |title=Plymouth Dockyard 1698 – 1843 |url=https://collection.sciencemuseumgroup.org.uk/people/cp136280/plymouth-dockyard |website=Science Museum Group |access-date=2 August 2019}}</ref> 

Most of these buildings and structures were rebuilt over ensuing years, including Dummer's original wet dock and dry dock (completely rebuilt in the 1840s and now known as No. 1 Basin and No. 1 Dock).<ref name="1DockListing">{{NHLE|desc=Listed building description|num=1388409|access-date=31 August 2016}}</ref> The terrace survived into the 20th century, but was largely destroyed in [[the Blitz]] along with several others of Devonport's historic buildings. Just one end section of the terrace survives; dating from 1692 to 1696, it is the earliest surviving building in any royal dockyard.<ref name="Terrace" />

===Subsequent development===
Once the dockyard was up and running, people (among them civilian workers from the dockyard) began to settle and build houses in the immediate vicinity. The settlement came to be known as [[Plymouth Dock]]; it was renamed [[Devonport, Plymouth|Devonport]] in 1824.<ref>{{cite book| title=Plymouth.

Engraving by [[Thomas Milton]] (1756) showing the extent of the yard before the Great Rebuilding.]]

The area where the dockyard began is now known as the South Yard. It was here that Dummer built his groundbreaking stone dry dock and basin. A further, double-dock (i.e. long enough to accommodate two ships of the line, end to end) was added, just north of the basin, in the 1720s.<ref>{{Cite web|url=https://historicengland.org.uk/listing/the-list/list-entry/1432153|title=No 2 Dock, including bollards and capstans, Non Civil Parish - 1432153 &#124; Historic England|website=historicengland.org.uk}}</ref> Slipways were also added in the early 18th century, either side of the dry docks, to enable shipbuilding to take place. The numbers employed at the yard increased from 736 in 1711 to 2,464 in 1730. Around this time the small cove on the south side of the dockyard was partially [[reclaimed]] to create an enclosed mast pond and ground which was used for storing timber.<ref name="DevCharStud">{{cite book |title=Devonport: Characterisation Study and Management Proposals |date=2006 |publisher=Plymouth City Council |location=Plymouth |pages=56–66 |url=https://www.plymouth.gov.uk/sites/default/files/Dv12aDevonportCharacterisationStudyOptimised.pdf |access-date=23 August 2023}}</ref> 

=====The Great Rebuilding=====

Centre front is Dummer's 1690s stone basin and dock: to its left, one double and two single dry docks; to its right, the 1761 double quadrangle storehouse. Behind the docks: pedimented workshops and the 1691 officers' terrace. On the right of the picture: building slips on the foreshore, then the smithery, timber stores, mast and boat houses, with the long 1760s roperies beyond them (in front of Mount Wise).]]

In the 1760s a period of expansion began, leading to a configuration which (despite subsequent rebuildings) can still be seen today : five [[slipways]], four [[dry docks]] and a basin. The two additional docks were built, in place of a pair of slips to the north of the double-dock, in 1762 and 1789.<ref name="PicPlymouth1812" /> (Slipways were used for shipbuilding, but the main business of the eighteenth-century yard was the repair, maintenance and equipping of the fleet, for which the dry docks and basin were used).<ref name="eh">{{cite web|url=http://m.english-heritage.org.uk/publications/thematic-survey-navy/|archive-url=http://webarchive.nationalarchives.gov.uk/20130204202749/http://m.english-heritage.org.uk/publications/thematic-survey-navy/|url-status=dead|archive-date=2013-02-04|title=Thematic Survey of English Naval Dockyards|first=English|last=Heritage}}</ref> New slips were built on the New Ground to the south. One slipway (Slip No.1 of 1774) survives unaltered from this period: a rare survival.<ref>{{NHLE|desc=Listed building description|num=1388431|access-date=31 August 2016}}</ref> It is covered with a timber superstructure of 1814, a similarly rare and early survival of its type; indeed, only three such timber slip covers have survived in Britain, two of them at Devonport. (The second, of similar vintage, stands over the former No.5 Slip; in 1870 it was converted to house a scrieve board, for full-size drafting of ship designs).<ref>{{NHLE|desc=Listed building description|num=1388417|access-date=31 August 2016}}</ref> 

[[File:Devonport South Yard - East Ropery.jpg|thumb|right|East Ropery (1763–71, rebuilt 1813–17)]]

Before the expansion could begin, a rocky hillside to the south had to be cut away; the rubble was used to [[Reclaimed land|reclaim]] the mudflats ready for building.<ref name="Coad2013" /> To open up the site, the old ropehouse was demolished and a new rope-making complex built alongside the east perimeter wall of the expanded site (where it still survives in part, albeit rebuilt following a fire in 1812). Where the old ropehouse had stood a short canal known as the Camber was laid out, terminating in a [[Ship's boat|boat]] basin with a [[boathouse]].<ref name="PicPlymouth1812" /> On the New Ground to the south a new smithery was constructed, in 1776, containing 48 forges; though subsequently rebuilt it too still stands, the earliest surviving smithery in any royal dockyard.<ref>{{NHLE|desc=Listed building description|num=1392692|access-date=31 August 2016}}</ref> Initially used for the manufacture of anchors and smaller metal items, it would later be expanded to fashion the iron braces with which wooden hulls and decks began to be strengthened; as such, it provided a hint of the huge change in manufacturing technology that would sweep the dockyards in the nineteenth century as sail began to make way for steam, and wood for iron and steel.<ref name=eh /> In the space between the new slips and the new ropehouse, south of the boat pond and smithery, was a sizeable mast pond, flanked by mast-houses.<ref name="PicPlymouth1812" /> 

The most imposing building of this period was a double-quadrangular storehouse of 1761 (probably designed by [[Thomas Slade]]); replacing the 17th-century Great Storehouse, it also incorporated a new rigging house and sail loft. It remained in use until it was destroyed in the [[Plymouth Blitz]]. The same fate befell several other buildings of the 18th and early 19th century, including a long and prominent [[pediment]]ed workshop with a central clocktower, built to accommodate a range of woodworkers and craftsmen, and an adjacent pedimented block containing the dockyard offices, as well as [[Edward Holl]]'s replacement Dockyard Church of 1814.<ref name=Coad2013>{{cite book|last1=Coad|first1=Jonathan|title=Support for the Fleet: architecture and engineering of the Royal Navy's bases 1700–1914|date=2013|publisher=English Heritage|location=Swindon}}</ref>

The dockyard suffered severe damage in a large-scale fire on 25 September 1840, which started in the North Dock on {{HMS|Talavera|1818|6}}. ''Talavera'' and {{HMS|Imogene|1831|2}} were completely gutted; the fire threatened {{HMS|Minden|1810|6}}, and spread to nearby buildings and equipment. Estimates for the damage were put at £150,000 in the values of the day, and would have totalled £500,000 had the fire not been contained by demolishing several surrounding buildings.<ref name="Morning Chronicle 1840">{{cite news |author1=<!--Staff writer(s); no by-line.--> |title=Dreadful Fire at Devonport |url=http://www.devonportonline.co.uk/historic_devonport/navy-dockyard/1840-fire/1840-fire.aspx |access-date=26 April 2020 |publisher=The Morning Chronicle |date=25 September 1840 |archive-url=https://web.archive.org/web/20190317100348/http://www.devonportonline.co.uk/historic_devonport/navy-dockyard/1840-fire/1840-fire.aspx |archive-date=17 March 2019 |location=London}}</ref>

The South Yard continued to be upgraded to keep abreast of changes in shipbuilding technology. The docks and slips were expanded and extended at various points in the 19th century, with the double dock being reconfigured to form a single dock (No. 2 Dock) in 1860. At the end of the century the mast ponds were filled in to provide room for a new and very much larger No. 3 Slip, designed for the construction of [[dreadnoughts]]. [[Machine shop]]s and plank stores were also put in place alongside.<ref name="DevCharStud" /> In 1912 the new No. 3 Slip was further extended in length, from {{convert|520|ft|abbr=on}} to {{convert|752|ft|abbr=on}}, ready for the building of the [[superdreadnought]] [[HMS Warspite (03)|HMS ''Warspite'']].<ref name="Coad2013" /> Meanwhile the 18th-century No. 1 Slip was converted into a [[patent slip]] for the repair of small craft, and in 1909 No. 2 Slip was made into a shallow dock for [[torpedo boats]].<ref>{{cite web|url=https://www.olddevonport.uk/Royal%20Dockyard-South%20Yard-Building%20Slip%202.htm|title=Building Slip 2 (Shallow Dock) |publisher=Old Deveonport|access-date=31 August 2024}}</ref>

The South Yard was drastically impacted by [[aerial bombardment]] during the Second World War: by the end of 1942, 85% of its buildings had been either heavily damaged or destroyed.<ref name="DevCharStud" />

Provision of ships' armaments was not the responsibility of the Navy but of the independent [[Board of Ordnance]], which already had a wharf and storage facility in the Mount Wise area of Plymouth. This, however, began to prove insufficient and in 1719 the board established a new gun wharf on land leased from one [[Sir Nicholas Morice, 2nd Baronet|Sir Nicholas Morice]], immediately to the north of the established Dockyard. The Morice Yard was a self-contained establishment with its own complex of workshops, workers, officers, offices and storehouses. Gunpowder was stored on site, which began to be a cause for concern among local residents (as was the older store in the [[Royal Citadel, Plymouth|Royal Citadel]] within the city of Plymouth); so new [[gunpowder magazine]]s were built further to the north, at Keyham, in the 1770s. (In the mid-19th century, to make room for the dockyard's expansion into Keyham, the gunpowder magazines were relocated to [[St Budeaux#19th century|Bull Point]], north of Weston Mill Lake).<ref>{{Cite web|url=http://m.english-heritage.org.uk/publications/thematic-survey-ordnance/|archive-url=https://web.archive.org/web/20140822013505/http://m.english-heritage.org.uk/publications/thematic-survey-ordnance/|url-status=dead|title=English Heritage: Thematic History of Ordnance Yards and Magazine Depots|archive-date=22 August 2014}}</ref>

In 1855 the Board of Ordnance was abolished and the [[War Office]] then took over management of the Morice Yard. Morice Ordnance Yard remained independent from the dockyard until 1941, at which point it was integrated into the larger complex. In contrast to South Yard, which fared badly in the Blitz, most of the original buildings survive at Morice Yard, enclosed behind their contemporary boundary wall; over a dozen of these are listed.<ref name="Listing" /> On higher ground behind the wharf itself is a contemporary terrace of houses for officers (1720), built from stone rubble excavated during the yard's construction.<ref name=eh /> 

Morice Yard remains part of the operational Naval Base; in 2022 it became the headquarters of [[Royal Navy Surface Fleet|Surface Fleet Command]].<ref name="COMSURFLOT">{{cite news |last1=Quayle |first1=Thomas |title=Royal Navy surface fleet command finds new home in Morice Yard |url=https://www.plymouthherald.co.uk/news/plymouth-news/royal-navy-surface-fleet-command-7105727 |access-date=19 August 2023 |work=Plymouth Live |date=20 May 2022}}</ref>

====The Devonport Lines====

[[File:Plan of Stoke Town and Plymouth Dock - Benjamin Donn, 1765.jpg|thumb|right|''A Plan of Stoke Town and Plymouth Dock'' dated 1765: showing the line of fortification (with associated military barracks) surrounding the gun wharf, town and dockyard (north is to the left)]]

In 1758, the Plymouth and Portsmouth Fortifications Act provided the means to construct a permanent landward defence for the dockyard complex. The Lines round Plymouth Dock (later 'Devonport Lines') were a [[bastion fort]]ification which consisted of an earthen [[Rampart (fortification)|rampart]] with a wide [[ditch (fortification)|ditch]] and a [[glacis]]. The lines ran from Morice Yard on the River Tamar, enclosing the whole dockyard and town, finally meeting the river again at Stonehouse Pool, a total distance of 2,000 yards (1,800 metres). There were four [[bastion]]s, Marlborough Bastion to the north, Granby Bastion to the north-east, Stoke Bastion to the east and George Bastion to the south east. There were originally two gates in the lines, the Stoke Barrier at the end of Fore Street and the Stonehouse Barrier. A third gate called New Passage was created in the 1780s, giving access to the [[Torpoint Ferry]]. After 1860, the fortifications were superseded by the [[Palmerston Forts, Plymouth|Palmerston Forts around Plymouth]] and the land occupied by the lines was either sold or utilised by the dockyard.<ref>{{cite web|url=http://www.plymouth.gov.uk/ppp_dock_lines.pdf |title=Plotting Plymouth's Past – Devonport's Dock Lines |website=www.plymouth.gov.uk |publisher=Old Plymouth Society |access-date=20 April 2016 |url-status=dead |archive-url=https://web.archive.org/web/20160428044331/http://www.plymouth.gov.uk/ppp_dock_lines.pdf |archive-date=28 April 2016 }}</ref> Also in 1860 the main dockyards' policing was transferred to the new [[History of the Ministry of Defence Police#1860: The Metropolitan Police|dockyard divisions of the Metropolitan Police]], in Devonport's case No. 3 Division, which remained in that role until 1934.<ref>{{Cite web|url=https://british-police-history.uk/f/royal-marine/|title=British Police History|website=british-police-history.uk}}</ref>

In the mid-nineteenth century, all royal dockyards faced the challenge of responding to the advent first of steam power and then metal hulls. Those unable to expand were closed; the rest underwent a transformation through growth and mechanisation. At Devonport, in 1864, a separate, purpose-built steam yard was opened on a self-contained site at Keyham, a little to the north of the Morice Yard (and a tunnel was built linking the new yard with the old). A pair of basins (8–9 acres each) were constructed: No. 2 Basin gave access to three large dry docks, while No. 3 Basin was the frontispiece to a huge integrated manufacturing complex. This 'steam factory' became known as the Quadrangle: it housed foundries, forges, pattern shops, boilermakers and all manner of specialized workshops. Two stationary steam engines drove [[line shaft]]s and heavy machinery, and the multiple flues were drawn by a pair of prominent chimneys. The building still stands, and is [[Grade I listed building|Grade I listed]]; architectural detailing was by [[Sir Charles Barry]]. [[English Heritage]] calls it 'one of the most remarkable engineering buildings in the country'.<ref name=eh />

[[File:HMS Westmister Undergoes Refit at Devonport MOD 45151169.jpg|thumb|upright|right|[[HMS Westminster (F237)|HMS ''Westminster'']] inside the Frigate Refit Complex, 2009]]

In the 1970s the three dry docks (Nos. 5, 6 and 7) were rebuilt, expanded and covered over to serve as an up-to-date Frigate Refit Complex.<ref name="HE">{{cite web|title=Devonport in the Twentieth Century|url=https://content.historicengland.org.uk/images-books/publications/twentieth-century-naval-dockyards-devonport-portsmouth-characterisation-report/part2-twentieth-century-naval-dockyards-devonport-portsmouth-characterisation.pdf/|website=Historic England}}</ref> They remain very much in use, together with the adjacent Quadrangle building, which (while extensively modernised within its original walls and roofs) continues to fulfil its original purpose, manufacturing items for ships in refit.<ref name="20cNavalDockyards2" /> 

=====RNEC Keyham=====
In 1880 a [[Royal Naval Engineering College]] was established at Keyham, housed in a new building just outside the dockyard wall alongside the Quadrangle where students (who joined at 15 years of age) gained hands-on experience of the latest naval engineering techniques. (The Engineering College moved to nearby [[Manadon]] in 1958; the [[Jacobethan]]-style building then went on to house the Dockyard Technical College for a time, but was demolished in 1985.)<ref name=Coad2013 />

=====The Naval barracks=====
Until the late nineteenth century, sailors whose ships were being repaired or refitted, or who were awaiting allocation to a vessel, were accommodated in floating [[Hulk (ship)|hulks]]. Construction of an onshore barracks, just north-east of the North Yard, was completed in 1889, with the barracks being named "HMS Vivid", after the [[HMS Vivid (1848)|base ship of the same name]]. It could accommodate 2,500 sailors and officers, and the first personnel moved in during June of that year. The barracks were renamed [[HMS Drake (shore establishment)|HMS ''Drake'']] on January 1, 1934;<ref name="Plymouthdata">{{cite web |last1=Moseley |first1=Brian |title=Royal Navy Barracks "HMS Vivid" / "HMS Drake" |url=http://www.plymouthdata.info/Royal%20Navy%20Estabs-RN%20Barracks.htm |website=Plymouth Data |archive-url=https://web.archive.org/web/20120318073336/http://www.plymouthdata.info/Royal%20Navy%20Estabs-RN%20Barracks.htm |access-date=14 March 2023|archive-date=18 March 2012 }}</ref> in the early 21st century the barracks area remained part of HMNB Devonport,<ref>{{cite web|url=https://www.royalnavy.mod.uk/locations-and-operations/bases-and-stations/hmnb-devonport|title=HMNB Devonport|publisher=Royal Navy|access-date=1 September 2024|quote=Hasler Naval Service Recovery Centre is in HMS Drake, which is part of HMNB Devonport.}}</ref> but was re-designated the [[HMS Drake (shore establishment)|Fleet Accommodation Centre]].<ref name="Handbook2010">{{Cite web|url=http://www.nff.org.uk/pdfdocs/devonport_naval_base_unit_information_booklet_nov09_smaller.pdf|archive-url=https://web.archive.org/web/20150405040735/http://www.nff.org.uk/pdfdocs/devonport_naval_base_unit_information_booklet_nov09_smaller.pdf|url-status=dead|title=Devonport Naval Base Handbook, 2010|archive-date=5 April 2015}}</ref> It remains in [[Ministry of Defence (United Kingdom)|Ministry of Defence]] ownership.<ref>{{cite web|url=https://historicengland.org.uk/images-books/publications/twentieth-century-naval-dockyards-devonport-portsmouth-characterisation-report/part2-twentieth-century-naval-dockyards-devonport-portsmouth-characterisation  |last1=Coats|first1=Ann|last2=Davies|first2=David|year=2013|title=20th Century Naval Dockyards: Devonport and Portsmouth Characterisation Report: Part 2|location=Portsmouth, Hants|publisher=Naval Dockyards Society|access-date=1 September 2024}}</ref>

====Keyham Extension====
[[File:Plymouth , Trafalgar Submarine at Devonport Naval Dockyard - geograph.org.uk - 1151394.jpg|thumb|left|The 80-ton crane, a landmark of the Submarine Refit Centre since 1977, was dismantled in 2008.]]

In 1895 the decision was taken to expand the Keyham Steam Yard to accommodate the increasing size of modern warships. By 1907 Keyham, now renamed the North Yard, had more than doubled in size with the addition of No. 4 and No. 5 Basins (of 10 and 35 acres respectively), linked by a very large lock-cum-dock (the North Lock), 730&nbsp;ft in length, alongside three more dry docks of a similar size (Nos. 8, 9 and 10), able to "accommodate ships larger than any war-vessel yet constructed".<ref>{{cite web|url=http://www.devonportonline.co.uk/historic_devonport/navy-dockyard/dockyard/1914-guide-dockyard.aspx|title=1914 Guide for Visitors to Devonport Dockyard|author=Liz Cook|access-date=19 March 2016}}</ref> At the northernmost end of the site the north-west promontory, together with the wharves facing on to Weston Mill Lake, functioned as a vast [[Coaling (ships)|coaling yard]] for the steam-powered fleet.<ref>{{cite web|url=https://www.worldnavalships.com/keyham_dockyard.htm|title=Keyham Dockyard|publisher=World Naval Ships|access-date=31 August 2024}}</ref>

In the 1970s a new Fleet Maintenance Base was built at the North West Corner of the North Yard; opened in 1978, it was commissioned as [[HMS Defiance|HMS ''Defiance'']] (remaining so until 1994, when it was amalgamated into HMS ''Drake''). At the same time, a new Submarine Refit Complex was created, alongside the Fleet Maintenance Base, in the north-west corner of No. 5 Basin. It opened in 1981.<ref name="20cNavalDockyards1" /> Within it, two new dry docks were created (Nos. 14 and 15) for nuclear-powered [[fleet submarine]]s, and between them an 80-ton [[Hammerhead crane|cantilever crane]], one of the largest in western Europe, was installed to lift nuclear cores from submarines for maintenance and refuelling.<ref name="HE" /> As part of the same works, the North Lock (at the opposite end of the basin) was divided to form two submarine docks (Nos. 11 and 12).<ref>{{cite web|url=https://navaldockyards.org/wp-content/uploads/2016/02/part2-twentieth-century-naval-dockyards-devonport-portsmouth-characterisation.pdf  |page=85|title=Twentieth century naval dockyards Devonport Portsmouth characterisation report|publisher=Naval Dockyard Society|access-date=31 August 2024}}</ref>

In 1993 the Submarine Refit Centre was upgraded following the announcement that Devonport was to become the Royal Navy's only nuclear refit yard; among other things Nos. 9 and 10 dry docks were strengthened and reconfigured so as to be able to accommodate the much larger [[Vanguard-class submarine]]s, which entered into service from that year;<ref name="20cNavalDockyards2" /> the work was completed by [[Carillion]] in 2002.<ref>{{cite web|url=https://www.isurv.com/directory_record/3911/carillion_construction_ltd_v_devonport_royal_dockland_2003|title=Cases – Carillion Construction Ltd v Devonport Royal Dockland |year=2003|publisher=RICS|access-date=31 August 2024}}</ref><ref>{{cite news|url=https://www.constructionnews.co.uk/sections/news/carillion-wins-10m-in-trident-dock-claim-12-05-2005/  |title=Carillion wins £10m in Trident dock claim|date=12 May 2005|newspaper=Construction News| access-date=31 August 2024}}</ref>

In 2011 the MOD sold the [[Freehold (law)|freehold]] of much of the North Yard to the Dockyard operator, Babcock; the site includes Basins No. 2 and No. 5 and their adjoining dry docks, together with the land between and around them (containing six listed buildings and structures, including the Grade I listed Quadrangle).<ref>{{cite web|title=MOD Heritage Report 2009–2011|url=https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/33359/heritage_rpt_200911.pdf/|website=UK Government}}</ref>

=====Weston Mill Lake=====
To the north of No. 5 Basin, land around Weston Mill Lake was reclaimed in the 1970s and the following decade the area (including the former coaling wharves) was repurposed to provide frigate berths for the [[Type 22 frigate|Type 22]] fleet.<ref>{{cite journal|url=http://www.icevirtuallibrary.com/doi/abs/10.1680/iwtme.1992.21672|title=Weston Mill Lake, HM Naval Base Devonport: Construction of a jetty using concrete caissons|year=1992|publisher=Institution of Civil Engineers|doi=10.1680/iwtme.1992.21672|access-date=15 July 2017|last1=MacIntyre|first1=H.|journal=Proceedings of the Institution of Civil Engineers - Water Maritime and Energy|volume=96|issue=4|pages=227–234}}</ref> It is now where the Navy's [[amphibious warfare ship]]s are based.

====Goschen Yard and post-war development====
The civilian streets around Devonport (like the dockyard itself) were heavily bombed during the Plymouth blitz. Post-war reconstruction was mainly focused on Plymouth itself. Several damaged streets in the vicinity of the dockyard were not rebuilt, but instead brought within Admiralty ownership to allow for future dockyard expansion.<ref name="20cNavalDockyards2" /> An area around Goschen Street, to the east of the North Yard, became known as the Goschen Yard: a factory and workshops were built on the site (which is now owned by Babcock); there was also an apprentice training centre (which later became part of [[City College Plymouth]]).<ref>{{cite web |title=Goschen Yard |url=https://www.olddevonport.uk/Royal%20Dockyard-Goschen%20Yard.htm |website=Old Devonport UK |access-date=22 August 2023}}</ref>

In 2005 a sizeable area of the historic town centre of Devonport, which had been annexed after the war and was known as the South Yard Enclave, was released from MOD ownership.<ref>{{cite book |title=Devonport Area Action Plan 2006-2021 |date=2007 |publisher=Plymouth City Council |location=Plymouth |pages=13–16 |url=https://www.plymouth.gov.uk/sites/default/files/DevonportChapters1To4.pdf |access-date=22 August 2023}}</ref> The area, west of Chapel Street and north of Duke Street, had since 1956 been enclosed behind a perimeter wall and used as a naval stores yard;<ref>{{cite web |title=Central Devonport |url=https://www.devonportonline.co.uk/millennium_devonport/visiting/central/central.aspx |website=Devonport Online |access-date=22 August 2023}}</ref> it has since been redeveloped with housing and other amenities.

The Naval base at Devonport is still nicknamed "Guzz" (or, sometimes, "Guz") by sailors and marines. One suggestion is that this originates from the word ''guzzle'' (to eat or drink greedily), which is likely to refer to the eating of [[cream tea]]s, a [[West Country]] delicacy and, therefore, one with strong connections to the area around [[Plymouth]].<ref>{{cite web|url=http://www.royalnavalmuseum.org/info_sheets_nicknames.htm |title=Pompey, Chats and Guz: the Origins of Naval Town Nicknames &#124; Online Information Bank &#124; Research Collections &#124; Royal Naval Museum at Portsmouth Historic Dockyard |publisher=Royalnavalmuseum.org |access-date=6 November 2012 |url-status=dead |archive-url=https://web.archive.org/web/20101220215401/http://royalnavalmuseum.org/info_sheets_nicknames.htm |archive-date=20 December 2010 }}</ref> Another explanation advanced is that "GUZZ" was the radio [[Radio call sign|call sign]] for the nearby Admiralty wireless station (which was GZX) at [[Devil's Point, Devon|Devil's Point]],<ref>{{cite web|url=http://www.plymouthdata.info/Royal%20Navy%20Estabs-RN%20Barracks.htm| website = The Encyclopaedia of Plymouth History|title=Plymouth, Royal Navy Establishments – Royal Naval Barracks (HMS Vivid / HMS Drake)|publisher=Plymouth Data| date = February 2011| archive-url = https://web.archive.org/web/20120318073336/http://www.plymouthdata.info/Royal%20Navy%20Estabs-RN%20Barracks.htm| archive-date = 18 March 2012| access-date = 13 February 2015|last=Moseley|first=Brian}} (citing Brimacombe, Peter, "The History of HMS Drake", Rodney Brimacombe, Mor Marketing, Plymouth, July 1992.)</ref> though this is disputed and has recently been disproved by reference to actual [[wireless telegraphy]] callsigns in existence over the past century.<ref>See, for example:{{cite web|url=http://www.godfreydykes.info/THE_PLYMOUTH_COMMAND.htm|title=THE_PLYMOUTH_COMMAND|access-date=20 August 2011|last=Dykes|first=Godfrey|archive-date=20 January 2015|archive-url=https://web.archive.org/web/20150120104416/http://www.godfreydykes.info/THE_PLYMOUTH_COMMAND.htm|url-status=dead}}</ref>

Another explanation is that the name came from the [[Hindi languages|Hindi]] word for a [[yard]] (36 inches), "[[guz]]", (also spelled "guzz", at the time) which entered the [[Oxford English Dictionary]],<ref>{{cite web|title=A Minor case: OED contributions from a prison cell |url=http://blog.oxforddictionaries.com/2013/02/william-minor/|archive-url=https://web.archive.org/web/20130216111334/http://blog.oxforddictionaries.com/2013/02/william-minor/|url-status=dead|archive-date=16 February 2013}}</ref> and Royal Navy usage,<ref>{{cite book|title=Royal Navy "Sailor's Pocket Book" |first= Sir Frederick |last=Bedford|year=1875 |url=https://books.google.com/books?id=BmABAAAAQAAJ&q=guz}}</ref> in the late 19th century, as sailors used to regularly abbreviate "The [[Dockyard Port of Plymouth|Dockyard]]" to simply "The Yard", leading to the slang use of the Hindi word for the unit of measurement of the same name.<ref>{{Cite web|url=http://www.godfreydykes.info/THE_PLYMOUTH_COMMAND.htm|title=THE_PLYMOUTH_COMMAND|website=www.godfreydykes.info|access-date=20 August 2011|archive-date=20 January 2015|archive-url=https://web.archive.org/web/20150120104416/http://www.godfreydykes.info/THE_PLYMOUTH_COMMAND.htm|url-status=dead}}</ref> The Plymouth Herald newspaper attempted<ref>{{cite web|url=http://www.plymouthherald.co.uk/Plymouth-Devonport-called-Guzz/story-16428801-detail/story.html|title=Why are Plymouth and Devonport called Guzz|work=Plymouth Herald|access-date=19 March 2016|archive-url=https://web.archive.org/web/20150924122242/http://www.plymouthherald.co.uk/Plymouth-Devonport-called-Guzz/story-16428801-detail/story.html|archive-date=24 September 2015|url-status=dead}}</ref> to summarise the differing theories, but no firm conclusion was reached.

===Admiral Superintendents of the yard===
In 1832 the [[Navy Board]] was abolished, everything except the gun wharves were brought under the direct control of the [[British Admiralty|Admiralty]]. A serving Royal Navy officer, usually of rear-admiral rank, was appointed as [[admiral-superintendent]] of the dockyard; however, the post was sometimes held by a commodore-superintendent or even a vice-admiral. They were responsible for all the civilian support services operated by the dockyard departments.
