140-647: His Majesty's Naval Base, Portsmouth ( HMNB Portsmouth ) is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Clyde and HMNB Devonport ). Portsmouth Naval Base is part of the city of Portsmouth ; it is located on the eastern shore of Portsmouth Harbour , north of the Solent and the Isle of Wight . For centuries it was officially known as HM Dockyard, Portsmouth : as
280-448: A Royal Dockyard , Portsmouth functioned primarily as a state-owned facility for building, repairing and maintaining warships ; for a time it was the largest industrial site in the world. From the 1970s, the term 'Naval Base' began to be used for Portsmouth (and other Royal Dockyards), acknowledging a greater focus on personnel and support elements alongside the traditional industrial emphases. In 1984 Portsmouth's Royal Dockyard function
420-546: A torpedo workshop (built to the east of No 12 dock in 1886). Before the end of the century, it was recognised that there would have to be still further expansion across all the Royal Dockyards in order to keep pace with the increasing likely size of future naval vessels. At Portsmouth two more dry docks, Nos 14 & 15, were built alongside the Repairing Basin in 1896; (within ten years these, together with

The mission ended in May 2011. The financial costs attached to nuclear deterrence, including Trident missile upgrades and replacements, have become an increasingly significant issue for the navy. HMS Raleigh at Torpoint, Cornwall ,
700-606: A comprehensive transformation, brought about by steam propulsion , metal ship construction, and explosive munitions. Despite having to completely replace its war fleet, the Navy managed to maintain its overwhelming advantage over all potential rivals. Owing to British leadership in the Industrial Revolution , the country enjoyed unparalleled shipbuilding capacity and financial resources, which ensured that no rival could take advantage of these revolutionary changes to negate
840-410: A dramatic and ongoing increase in the potential size of new vessels. The Dockyards found themselves having to expand in kind. At Portsmouth, plans were drawn up in the late 1850s for further land reclamation north and east of the new Steam Basin, and from 1867 work was begun on a complex of three new interconnected basins, each of 14–22 acres. Each basin served a different purpose: ships would proceed from
980-414: A freshwater well, to enable water to be pumped through a network of pipes to various parts of the dockyard. A table engine , designed by Bentham's staff chemist James Sadler , was installed in 1799; it represented the first use of steam power in a Royal Naval Yard. By 1800 a second steam engine (a Boulton & Watt beam engine) was being installed alongside the first. Meanwhile, Bentham designed and built
1120-478: A gradual decline in its fleet size in accordance with the changed strategic environment it operated in. While new and more capable ships are continually brought into service, such as the Queen Elizabeth -class aircraft carriers , Astute -class submarines , and Type 45 destroyers , the total number of ships and submarines operated has continued to steadily reduce. This has caused considerable debate about
1260-475: A heavy reliance upon impressed labour. This would result in problems countering large, well-armed United States Navy frigates which outgunned Royal Naval vessels in single-opponent actions, as well as United States privateers, when the American War of 1812 broke out concurrent with the war against Napoleonic France and its allies. The Royal Navy still enjoyed a numerical advantage over the former colonists on
1400-599: A key part in establishing and defending the British Empire , and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority. Following World War I , it was significantly reduced in size. During the Cold War , the Royal Navy transformed into a primarily anti-submarine force , hunting for Soviet submarines and mostly active in
1540-463: A larger scale. The three great storehouses (Nos 9, 10 & 11) were built between 1764 and 1785 on a wharf, alongside a deep canal (or camber ) which allowed transport and merchant vessels to moor and load or unload goods; the camber was rebuilt in Portland stone between 1773 and 1785. On the other side of the camber, on newly reclaimed land, two more sizeable brick storehouses were built to serve as

#17327984688301680-428: A military threat to England, the strategic importance of Portsmouth grew. In 1689, Parliament ordered a new dry dock to be built there, large enough to accommodate the latest first-rate and second-rate ships of the line (which were too big for the existing docks). Work began in 1691; as with all subsequent extensions to the dockyard, the new works were built on reclaimed land (on what had been mud flats, to north of

Following the Glorious Revolution of 1688, England joined the War of the Grand Alliance which marked the end of France 's brief pre-eminence at sea and the beginning of an enduring British supremacy which would help with the creation of the British Empire. In 1707, the Scottish navy was united with the English Royal Navy. On Scottish men-of-war,

John's flight to Winchester and his death later that year left the Earl of Pembroke as regent, and he was able to marshal ships to fight the French in the Battle of Sandwich in 1217 – one of the first major English battles at sea. The outbreak of the Hundred Years War emphasised the need for an English fleet. French plans for an invasion of England failed when Edward III of England destroyed
2100-526: A new chapel ( St Ann's Church ) was built nearby. At the same time a set of offices for the senior officers of the yard was built (in place of an earlier office block), overlooking the docks and basin; it continues to provide office space to this day. After the old Commissioner's House had been demolished, four identical quadrangular buildings were built, flanking the timber ground east of the Basin; as well as providing storage space, they accommodated workshops for
2240-551: A peak of efficiency, dominating the navies of all Britain's adversaries, which spent most of the war blockaded in port. Under Lord Nelson , the navy defeated the combined Franco-Spanish fleet at Trafalgar (1805). Ships of the line and even frigates, as well as manpower, were prioritised for the naval war in Europe, however, leaving only smaller vessels on the North America Station and other less active stations, and
2380-497: A range of vessels, including so-called "motherships" planned for procurement by the Royal Fleet Auxiliary. The Hunt-class vessels combine the separate roles of the traditional minesweeper and the active minehunter in one hull. If required, the vessels can take on the role of offshore patrol vessels. A fleet of eight River-class offshore patrol vessels are in service with the Royal Navy. The three Batch 1 ships of

The Great Ropehouse, a double ropery over 1,000 ft (300 m) in length, dates from the same period. It is, however, the sixth ropehouse (since 1665) to have stood on the site. Both its immediate predecessors were destroyed by fire (in 1760 and 1770) and
2660-479: A second dry dock (called the "North Stone Dock" after it was rebuilt with stone altars in 1737, and known today as No 6 dock). Severed from the harbour, the Upper Wet Dock became a reservoir into which water from various nearby dry docks could be drained; it was vaulted and covered over at the end of the eighteenth century, but still exists today underground. By 1700 a shipbuilding slip had been constructed off

Tanks installed on the upper floor provided a head of water for Bentham's aforementioned dockyard-wide pipe network, providing both salt water for firefighting and fresh water for various uses (including, for
2940-433: A series of workshops: for construction and repair of boilers, for punching and shearing and for heavy turning ; there was also an erecting shop for assembling the finished engines. The upper floor housed pattern shops, fitting shops and other light engineering workshops. Line shafts throughout were powered by an 80 hp steam engine accommodated to the rear. A new Brass and Iron Foundry was also built soon afterwards, on

#17327984688303080-473: A single force. During the early 17th century, England's relative naval power deteriorated until Charles I undertook a major programme of shipbuilding. His methods of financing the fleet contributed to the outbreak of the English Civil War , and the abolition of the monarchy . The Commonwealth of England replaced many names and symbols in the new Commonwealth Navy, associated with royalty and
3220-448: A small permanent core of warships in peacetime. England's naval organisation was haphazard and the mobilisation of fleets when war broke out was slow. Control of the sea only became critical to Anglo-Saxon kings in the 10th century. In the 11th century, Aethelred II had a large fleet built by a national levy. During the period of Danish rule in the 11th century, authorities maintained a standing fleet by taxation, and this continued for
3360-814: A time under Edward the Confessor , who frequently commanded fleets in person. After the Norman Conquest , English naval power waned and England suffered large naval raids from the Vikings. In 1069, this allowed for the invasion and ravaging of England by Jarl Osborn, brother of King Svein Estridsson , and his sons. The lack of an organised navy came to a head during the First Barons' War , in which Prince Louis of France invaded England in support of northern barons. With King John unable to organise

A new smithery was also built nearby, immediately to the north (the latest in a succession of smiths' shops to have been built on the site); dating from 1791, it was mainly occupied with anchor making. Ten years later this process was vividly described: "The immense masses of the anchors,

Queen Elizabeth began sea trials in June 2017, was commissioned later that year, and entered service in 2020, while the second, HMS Prince of Wales , began sea trials on 22 September 2019, was commissioned in December 2019 and was declared operational as of October 2021. The aircraft carriers form a central part of the UK Carrier Strike Group alongside escorts and support ships. Amphibious warfare ships in current service include two landing platform docks ( HMS Albion and HMS Bulwark ). While their primary role

The UK government has committed to replace these submarines with four new Dreadnought -class submarines , which will enter service in the "early 2030s" to maintain this capability. Commander-in-Chief Naval Home Command As the Royal Navy's size decreased during the Cold War , commands were amalgamated. In 1969, the Home and Mediterranean Fleets were amalgamated, and on shore,

The area controlled from Bermuda (and Halifax until 1905) had been part of the North America Station, until the 1820s, which then absorbed the Jamaica Station to become
10920-463: The adjacent docks 12 & 13, had to be extended, and by the start of World War I Dock No 14 was over 720 ft in length). In 1843 construction began on a railway system within the dockyard. In 1846 this was connected to Portsmouth Town railway station via what became known as the Admiralty Line. By 1952 there was over 27 miles of track within the dockyard. Its use declined in the 1970s:
11060-402: The age of 14, this was the forerunner of Portsmouth Dockyard School (later Technical College) which continued to provide specialist training until 1970. The adoption of steam propulsion for warships led to large-scale changes in the Royal Dockyards, which had been built in the age of sail . The Navy's first 'steam factory' was built at Woolwich in 1839; but it soon became clear that the site
11200-646: The area in 1212. The docks were used by various kings when embarking on invasions of France through the 13th and 14th centuries, including the Saintonge War in 1242. Edward II ordered all ports on the south coast to assemble their largest vessels at Portsmouth to carry soldiers and horses to the Duchy of Aquitaine in 1324 to strengthen defences. The first recorded dry dock in the world was built in Portsmouth by Henry VII in 1495. The first warship built here
11340-574: The beginning of the war without the loss of a single life. The Royal Navy nevertheless remained active in other theatres, most notably in the Mediterranean Sea , where they waged the Dardanelles and Gallipoli campaigns in 1914 and 1915. British cruisers hunted down German commerce raiders across the world's oceans in 1914 and 1915, including the battles of Coronel , Falklands Islands , Cocos , and Rufiji Delta , among others. At
11480-474: The boat pond and boat houses; so in 1845 a new facility (No 6 Boathouse) was built alongside the mast pond, to the south, which was converted into a boat pond.) Three new dry docks were constructed over the next 20 years, opening off the new basin, and another was built on reclaimed land west of the basin, immediately north of the shipbuilding slips. The slips were now five in number, with Nos. 3–5 being covered by interlinking metal roofs (believed to have comprised

The vessel MV Grampian Frontier is leased from Scottish-based North Star Shipping for patrol duties around the British Indian Ocean Territory . However, she is not in commission with
11760-480: The continued rebuilding at Portsmouth and initiated further key engineering works. A prolific inventor and precision engineer, Bentham's initiatives at Portsmouth ranged from instituting new management principles in the manufacturing departments to developing the first successful steam-powered bucket dredger , which began work in the harbour in 1802. The 1761 rebuilding plan had envisaged the old wooden double dock being refurbished, but Bentham instead proposed expanding
11900-667: The cross of St Andrew was replaced with the Union Jack. On English ships, the red, white, or blue ensigns had the St George's Cross of England removed from the canton, and the combined crosses of the Union flag put in its place. Throughout the 18th and 19th centuries, the Royal Navy was the largest maritime force in the world, maintaining superiority in financing, tactics, training, organisation, social cohesion, hygiene, logistical support and warship design. The peace settlement following
12040-415: The current building was itself gutted by fire in 1776 as the result of an arson attack . It was called a 'double' ropery because the spinning and laying stages took place in the same building (on different floors) rather than on two separate sites. Other buildings associated with ropemaking (including hemp houses, a hatchelling house, tarring house and storehouses) were laid out alongside and parallel to
12180-714: The early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France . The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the UK's armed services , it is consequently known as the Senior Service . From the 19th century until the Second World War , it was the world's most powerful navy. The Royal Navy played
12320-573: The eastern Pacific Ocean (after the war, the Royal Navy's Bermuda-based North America and West Indies Station was consequently re-designated the America and West Indies station , including a South American division. The rising power and increasing belligerence of the Japanese Empire after World War I, however, resulted in the construction of the Singapore Naval Base , which was completed in 1938, less than four years before hostilities with Japan did commence during World War II . In 1932,
12460-447: The edges of the basins: five cranes, seven caissons and forty capstans were run on compressed air from the pump house. The "Great Extension" of Portsmouth Dockyard was largely completed by 1881. Alongside the new Basins new buildings were erected, on a huge scale, to accommodate new manufacturing and construction processes. These included a gun-mounting workshop (built alongside the pumping station in 1881) which produced gun turrets , and
12600-532: The end of World War I, the Royal Navy remained by far the world's most powerful navy, larger than the U.S. Navy and French Navy combined, and over twice as large as the Imperial Japanese Navy and Royal Italian Navy combined. Its former primary competitor, the Imperial German Navy, was destroyed at the end of the war . In the inter-war period , the Royal Navy was stripped of much of its power. The Washington and London Naval Treaties imposed
12740-420: The entrance to the basin (another innovation which soon became a standard design). To deal with the increasing number of docks, Bentham in 1797 proposed replacing one of the horse pumps above the reservoir with a steam engine. His plan was that the engine should be used not only to drain the reservoir (by night) but also to drive a sawmill and woodworking machinery (during the day); he also envisaged linking it to
12880-401: The first time, provision of drinking water to ships on the wharves) sourced from a newly sunk 274 ft well. Between the two Wood Mills buildings a single-storey workshop was built in 1802 to accommodate what soon came to be recognised as the world's first steam-powered factory for mass production: Portsmouth Block Mills . Marc Brunel , father of Isambard Kingdom Brunel , famously designed
13020-458: The first two years of the war. Over 3,000 people were lost when the converted troopship Lancastria was sunk in June 1940, the greatest maritime disaster in Britain's history. The Navy's most critical struggle was the Battle of the Atlantic defending Britain's vital North American commercial supply lines against U-boat attack. A traditional convoy system was instituted from the start of
13160-436: The foreign and defence policies of His Majesty's Government through the exercise of military effect, diplomatic activities and other activities in support of these objectives. It is also a key element of the British contribution to NATO, with a number of ships or aircraft allocated to NATO tasks at any time. In 2007 core capabilities were described as: The English Royal Navy was formally founded in 1546 by Henry VIII , though
13300-456: The great historical garrison commands of Commander-in-Chief, Portsmouth and Commander-in-Chief, Plymouth were combined in July 1969. The result was Naval Home Command. In 1992 establishments under the command's jurisdiction included Flag Officer, Portsmouth ; Flag Officer Plymouth ; activities at Portland; Flag Officer Scotland and Northern Ireland ; Commodore HMNB Clyde ; Training; Reserves; and Chief Executive Marine Services . In 1976
13440-463: The isles though Alexander III was ultimately successful in asserting Scottish control. The Scottish fleet was of particular import in repulsing English forces in the early 14th century. A standing "Navy Royal", with its own secretariat, dockyards and a permanent core of purpose-built warships, emerged during the reign of Henry VIII. Under Elizabeth I , England became involved in a war with Spain , which saw privately owned vessels combining with
13580-614: The last Admiral Commanding, Reserves hauled down his flag. Included: Other Royal Navy shore establishments also reported to CINCNAVHOME. In 1994 the post of Commander-in-Chief Naval Home Command was unified with that of the Second Sea Lord following the rationalisation of the British Armed Forces following the end of the Cold War. The staff were housed in a new Victory Building at Portsmouth. By 2006,
13720-501: The last time before his death at the Battle of Trafalgar. From 1814 wooden covers were built over some of the slips and docks, to designs by Robert Seppings . From 1815 the system of Dockyard apprenticeship was supplemented by the establishment of a School of Naval Architecture in Portsmouth (for training potential Master Shipwrights), initially housed in the building which faces Admiralty House on South Terrace. Taking on students from
13860-525: The link to the mainline was closed in 1977 and locomotives ceased operating within the yard the following year. In 1876 a railway station was built on what became known as South Railway Jetty on Watering Island (west of the Semaphore Tower). It was served by a separate branch line which crossed the South Camber by way of a swing bridge and continued on a viaduct over the foreshore , joining
14000-401: The machines, which manufactured ships' pulley blocks through a total of fifteen separate stages of production. Having been presented with Brunel's designs, which would be built by Henry Maudslay , Bentham incorporated them into his woodworking complex and linked them to the engines by way of line shafts . At the same time as building his Wood Mills, Bentham, with his deputy Simon Goodrich ,
14140-482: The main line just east of Portsmouth Harbour railway station . A small railway station and ornamental cast-iron shelter served in particular the needs of Queen Victoria and her family, who would often transfer from yacht to train at this location; this line soon became the main arrival/departure route for personnel. The swing bridge and viaduct were damaged in the wartime blitz and subsequently dismantled in 1946. The Royal Naval Railway Shelter has recently been moved to
14280-564: The mid-1500s, no new naval vessels were built here until 1648, but ships from Portsmouth were a key part of the fleet that drove off the Spanish Armada in 1588. Naval shipbuilding at Portsmouth recommenced under the English Commonwealth , the first ship being the eponymous fourth-rate frigate Portsmouth launched in 1650. (Portsmouth had been a parliamentarian town during the civil war .) A resident Commissioner
14420-614: The museum ship HMS M33 ). North of the reservoir a channel was dug leading to a new boat basin, beyond which several shipbuilding slips were constructed on reclaimed land at what became known as the North Corner of the dockyard. The rest of the reclaimed land was given over to storage space for timber with saw pits and seasoning sheds alongside, as shown in the dockyard model of 1774. Several of Portsmouth Dockyard's most notable historic buildings date from this period, with several older wooden structures being replaced in brick on
14560-744: The navy to meet its commitments. In December 2019 the First Sea Lord , Admiral Tony Radakin , outlined a proposal to reduce the number of Rear-Admirals at Navy Command by five. The fighting arms (excluding Commandant General Royal Marines ) would be reduced to commodore (1-star) rank and the surface flotillas would be combined. Training would be concentrated under the Fleet Commander . The Royal Navy has two Queen Elizabeth -class aircraft carriers. Each carrier cost £ 3 billion and displaces 65,000 tonnes (64,000 long tons; 72,000 short tons). The first, HMS Queen Elizabeth , commenced flight trials in 2018. Both are intended to operate
14700-570: The north of the Mary Rose will not be ceded for several years at least, due to the site's proximity to the berth of the new Queen Elizabeth-class aircraft carriers . Along with Woolwich , Deptford , Chatham and Plymouth , Portsmouth has been one of the main Royal Navy Dockyards or Bases throughout its history. Richard I ordered construction of the first dock on the site in 1194, while his successor John added walls around
14840-540: The old double dock) and the civil engineering involved was on an unprecedented scale. The work was entrusted to Edmund Dummer , naval engineer and surveyor to the Navy Board . His new dry dock (the "Great Stone Dock" as it was called) was built to a pioneering new design, using brick and stone rather than wood and with an increased number of 'altars' or steps (the stepped sides allowed shorter timbers to be used for shoring and made it much easier for shipwrights to reach
14980-612: The other Royal Dockyards). A substantial planned programme of expansion and modernisation was undertaken from 1761 onwards, driven (as would be future periods of expansion) by increases both in the size of individual ships and in the overall size of the fleet. In the 1760s the Lower Wet Dock (by then known as the Great Basin) was deepened, the Great Stone Dock was rebuilt and a new dry dock (known today as No 4 dock)
15120-531: The other side of the island and restored. By the end of the 19th century No 5 Slip had been uncovered and extended (to a length of 666 feet (203 m)) to become the yard's principal shipbuilding slip. At the same time the adjacent dry dock (No 9) was filled in to provide space for stacking steel plates, alongside which a further smithery (No 3 Engine Smithery) was erected in 1903. Meanwhile, slips 1–4 were repurposed (being no longer large enough for warship construction). Before long Nos 4 and 3 had been filled in, and
15260-489: The ponderous hammers, the vast size of the bellows, the roaring of the flaming furnaces, the reverberations of the falling cumbrous hammers, and the fiery pieces of metal flying in all directions, are truly awful, grand and picturesque". In 1796 Samuel Bentham was appointed Inspector General of Naval Works by the Admiralty with the brief of modernising the Royal Dockyards. As such, he took on responsibility for overseeing
15400-483: The repairing basin, to the rigging basin, to the fitting-out basin, and exit from there into a new tidal basin, ready to take on fuel alongside the sizeable coaling wharf there. Three dry docks were also constructed as part of the plan, as well as parallel pair of sizeable locks for entry into the basin complex; the contemporary pumping station which stands nearby not only served to drain these docks and locks, but also delivered compressed air to power equipment around
15540-495: The ropehouse; they largely date from the same period. Later, in 1784, a large new house was built for the Dockyard Commissioner. Unusually for the time it was designed by a civilian architect ( Samuel Wyatt , with Thomas Telford as clerk-of-works); most other dockyard buildings were designed in-house. The dockyard chapel , built eighty years earlier, was demolished to make way for the new Commissioner's house and
15680-688: The scrapping of some capital ships and limitations on new construction. The lack of an imperial fortress in the region of Asia , the Indian Ocean , and the Pacific Ocean was always to be a weakness throughout the 19th century as the former North American colonies that had become the United States of America had multiplied towards the Pacific Coast of North America, and the Russian Empire and Japanese Empire both had ports on
15820-411: The size of the Royal Navy. A 2013 report found that the Royal Navy was already too small, and that Britain would have to depend on her allies if her territories were attacked. The Royal Navy was responsible for training the fledgling Iraqi Navy and securing Iraq's oil terminals following the cessation of hostilities in the country. The Iraqi Training and Advisory Mission (Navy) ( Umm Qasr ), headed by
15960-406: The south; the yard's one shipbuilding slip (completed in 1651) stood between the two docks. These would all have been built of timber, rather than stone. By 1660 the dockyard had, in addition to these large-scale facilities for shipbuilding and repairs, a new rope house (1,095 ft (334 m) in length) and a variety of small storehouses, workshops and dwellings arranged around the site, which
16100-558: The southern edge of the basin, and in 1852 the Great Steam Smithery was opened alongside the Steam Factory (where Bentham's Metal Mills had formerly stood), containing a pair of steam hammers designed by James Nasmyth . The infrastructure and buildings were designed by a group of Royal Engineer officers, overseen by Captains Sir William Denison and Henry James . (The new steam basin was built over what had been
16240-560: The space beneath their cast iron covers converted into a shipbuilding workshop (No 3 Ship Shop); the neighbouring No 2 Slip was used for hauling up torpedo boat destroyers for a time, while No 1 was used as a boat slip. Royal Navy The Royal Navy ( RN ) is the naval warfare force of the United Kingdom , British Overseas Territories and Crown Dependencies , and a component of His Majesty's Naval Service . Although warships were used by English and Scottish kings from
16380-615: The space between the new North and South dry docks on the eastern side of the basin. In 1860 policing of the dockyard was also transferred to the new No. 2 Division of the Metropolitan Police , a role it fulfilled until 1933. Technological change affected not only ships' means of propulsion, but the materials from which they were built. By 1860 wooden warships, vulnerable as they were to modern armaments, had been rendered largely obsolescent. The changeover to metal hulls not only required new building techniques, but also heralded
16520-416: The start of World War II in 1939, the Royal Navy was still the largest in the world, with over 1,400 vessels. The Royal Navy provided critical cover during Operation Dynamo , the British evacuations from Dunkirk , and as the ultimate deterrent to a German invasion of Britain during the following four months. The Luftwaffe under Hermann Göring attempted to gain air supremacy over southern England in
16660-401: The two aircraft carriers, HMS Queen Elizabeth and HMS Prince of Wales . Naval logistics, accommodation and messing are provided on site, with personnel support functions (e.g. medical and dental; education; pastoral and welfare) provided by Defence Equipment and Support . Other functions and departments, e.g. Navy Command Headquarters support staff, are also accommodated within
16800-424: The underside of vessels needing repair). Extensively rebuilt in 1769, the Great Stone Dock is now known as No.5 dock. Along with the new dock, Dummer proposed that two wet docks (non-tidal basins) be built: the first ("Lower") Wet Dock was entered directly from the harbour and provided access to the Great Stone Dock; since much expanded, it remains in place (now known as "No. 1 Basin"). The second ("Upper") Wet Dock
16940-587: The use of Victory as flagship. The Second Sea Lord is now based at the Henry Leach Building on Whale Island , which is also the headquarters of the Fleet Commander . Some of the following ships (e.g. the patrol vessels) are not based in Portsmouth, but form part of the Portsmouth Flotilla . In changes to base porting arrangements announced in November 2017, HM Ships Westminster , Richmond , Kent and St Albans were to move to
17080-502: The war, but German submarine tactics, based on group attacks by " wolf-packs ", were much more effective than in the previous war, and the threat remained serious for well over three years. After World War II, the decline of the British Empire and the economic hardships in Britain forced the reduction in the size and capability of the Royal Navy. The United States Navy instead took on the role of global naval power. Governments since have faced increasing budgetary pressures, partly due to
17220-417: The widest iron span in Britain when built in 1845). Developments in shipbuilding technology, however, led to several of the new amenities having to be rebuilt and expanded (almost as soon as they were finished). A much larger Iron Foundry was opened in 1861, immediately to the east of its predecessor; it was further expanded in the following decade. In 1867 a very large Armour Plate Workshop was opened, filling
17360-510: The world. The former Block Mills are of international significance, having been the first factory in the world to employ steam-powered machine tools for mass production. The Royal Naval Museum has been on the site since 1911. In 1985 a partnership between the Ministry of Defence and Portsmouth City Council created the Portsmouth Naval Base Property Trust to manage part of the historic south-west corner of
17500-617: Was acquired in 2023 to act as a mothership for autonomous minehunting systems. The Royal Navy also includes a number of smaller non-commissioned assets such as the Sea-class workboats . On 29 July 2022, the Royal Navy christened a new experimental ship, XV Patrick Blackett , which it aims to use as a testbed for autonomous systems. Whilst the ship flies the Blue Ensign , it is crewed by Royal Navy personnel and will participate in Royal Navy and NATO exercises. The Submarine Service
17640-412: Was also established nearby. The Wood Mills, Block Mills, Metal Mills and Millwrights' department were all placed under Goodrich's supervision as Mechanist to the Royal Navy. In 1800, the Royal Navy had 684 ships and the Dockyard was the largest industrial complex in the world. In 1805 Horatio Nelson toured the newly opened block mills before embarking from Portsmouth on HMS Victory , leaving Britain for
17780-411: Was built alongside it over a five-year period from 1767. During 1771–76 the former Upper Wet Dock was reconfigured to serve as a reservoir into which water from the dry docks could be drained by way of culverts (enabling ships to be dry docked much more speedily). From 1789 work was begun on replacing the old wooden South Dock with a modern stone dry dock (known today as No 1 dock, it currently accommodates
17920-437: Was built at around this time (Long Row, 1715–19); later in the century it was joined by a further terrace (Short Row, 1787). In 1733 a Royal Naval Academy for officer cadets was established within the Dockyard, the Navy's first shore-based training facility and a forerunner of Britannia Royal Naval College in Dartmouth . The second half of the eighteenth century was a key period in the development of Portsmouth (and indeed of
18060-422: Was constructing a Metal Mills complex a little to the north-east. Alongside a smithery were a copper-smelting furnace and refinery , and a steam engine which drove a rolling mill and tilt hammers . Begun in 1801, these facilities were for recycling the copper sheathing of ships' hulls. In 1804 the works were extended to accommodate machinery for the rolling of iron to make bars and bolts. A millwrights ' shop
18200-656: Was contrary to widespread prewar expectations that in the event of a Continental conflict Britain would primarily provide naval support to the Entente Powers while sending at most only a small ground army. Nevertheless, the Royal Navy played an important role in securing the British Isles and the English Channel , notably ferrying the entire British Expeditionary Force to the Western Front at
18340-427: Was entered by way of a channel. To empty the dry dock, Dummer designed a unique system which used water from the Upper Wet Dock to drive a water-wheel on the ebb tide , which in turn powered a set of pumps. (At high tide, an auxiliary set of pumps was used, powered by a horse gin .) In 1699 Dummer adapted the channel leading to the Upper Wet Dock, enabling it to be closed off at each end by a set of gates, thus forming
18480-399: Was far too small to cope with this revolutionary change in ship building and maintenance. Therefore, in 1843, work began in Portsmouth on further reclamation of land to the north of the then Dockyard to create a new 7-acre basin (known today as No 2 Basin) with a sizeable factory alongside for manufacturing marine steam engines . The Steam Factory, on the western edge of the basin, housed
18620-524: Was first appointed in 1649; fifteen years later the Commissioner was provided with a house, and extensive gardens, at the centre of the yard. A new double dry dock (i.e. double the standard length so as to accommodate two ships at once) was built by the Commonwealth government in 1656, on what was then the tip of land at the north-west corner of the yard. It was joined by a single dry dock, just to
18760-516: Was now enclosed by a wooden palisade . After the Restoration , there was continued investment in the site with the excavation of a new mast pond, begun in 1664, alongside which a mast house was built in 1669. Between 1665 and 1668 Bernard de Gomme fortified the dockyard with an earthen rampart (complete with one bastion and two demi-bastions ), as part of his wider fortification of Portsmouth and Gosport . As France began to pose more of
18900-623: Was now in question. The Royal Navy clearance diving unit, the Fleet Diving Squadron, was reorganised and renamed the Diving and Threat Exploitation Group in 2022. The group consists of five squadrons: Alpha, Bravo, Charlie, Delta, and Echo. The Royal Navy has a separate unit with divers the special forces unit the Special Boat Service . The escort fleet comprises guided missile destroyers and frigates and
19040-409: Was significantly downsized and downgraded, and was formally renamed the 'Fleet Maintenance and Repair Organisation' (FMRO). The FMRO was privatised in 1998; in 2002, shipbuilding (which had not taken place on site since the late 1960s) resumed in the form of block construction , but this again ceased in 2014. Today, Portsmouth is the home base for two-thirds of the Royal Navy surface fleet , including
19180-668: Was sold to the Royal Australian Navy in 2011. In November 2006, the First Sea Lord Admiral Sir Jonathon Band described the Royal Fleet Auxiliary vessels as "a major uplift in the Royal Navy's war fighting capability". In February 2023, a commercial vessel was also acquired to act as a Multi-Role Ocean Surveillance (MROS) Ship for the protection of critical seabed infrastructure and other tasks. She entered service as RFA Proteus . An additional vessel, RFA Stirling Castle ,
19320-542: Was the Sweepstake of 1497; of more significance were the carracks Mary Rose of 1509 and Peter Pomegranate of 1510—both were rebuilt here in 1536. The wreck of the Mary Rose (which capsized in 1545, but was raised in 1982) is on display in a purpose-built museum. A fourth Tudor warship was the galleass Jennett , built in 1539 and enlarged as a galleon in 1559. The appointment of one Thomas Jermyn as Keeper of
19460-406: Was thwarted by the defeat of their escort fleet in the extraordinary Battle of Quiberon Bay in 1759, fought in dangerous conditions. In 1762, the resumption of hostilities with Spain led to the British capture of Manila and of Havana , along with a Spanish fleet sheltering there. British naval supremacy could however be challenged still in this period by coalitions of other nations, as seen in
19600-653: Was to search for and destroy Soviet submarines in the North Atlantic, and to operate the nuclear deterrent submarine force. The navy received its first nuclear weapons with the introduction of the first of the Resolution -class submarines armed with the Polaris missile . Following the conclusion of the collapse of the Soviet Union and the end of the Cold War in 1991, the Royal Navy began to experience
