The **Royal Navy** (**RN**) is the United Kingdom's naval warfare force and a component of His Majesty's Naval Service. Although warships were used by English and Scottish kings from 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 early 16th century; the oldest of the UK's armed services, it is consequently known as the **Senior Service**.

From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid-18th century until the Second World War, it was the world's most powerful navy. The Royal Navy played 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 globally. Owing to this historical prominence, it is common, even among non-Britons, to refer to it as "the Royal Navy" without qualification. Following World War I, it was significantly reduced in size, although at the onset of World War II it was still the world's largest. During the Cold War, the Royal Navy transformed into a primarily anti-submarine force, hunting for Soviet submarines and mostly active in the GIUK gap. Following the collapse of the Soviet Union, its focus has returned to expeditionary operations around the world and it remains one of the world's foremost blue-water navies.

The Royal Navy maintains a fleet of technologically sophisticated ships, submarines, and aircraft, including 2 aircraft carriers, 2 amphibious transport docks, 4 ballistic missile submarines (which maintain the nuclear deterrent), 6 nuclear fleet submarines, 6 guided missile destroyers, 11 frigates, 9 mine-countermeasure vessels and 26 patrol vessels. As of April 2023, there are 70 operational commissioned ships (including submarines as well as one historic ship, HMS *Victory*) in the Royal Navy, plus 13 ships of the Royal Fleet Auxiliary (RFA); there are also five Merchant Navy ships available to the RFA under a private finance initiative. The RFA replenishes Royal Navy warships at sea, and augments the Royal Navy's amphibious warfare capabilities through its three Bay-class landing ship vessels. It also works as a force multiplier for the Royal Navy, often doing patrols that frigates used to do.

The Royal Navy is part of His Majesty's Naval Service, which also includes the Royal Marines and the Royal Fleet Auxiliary. The professional head of the Naval Service is the First Sea Lord who is an admiral and member of the Defence Council of the United Kingdom. The Defence Council delegates management of the Naval Service to the Admiralty Board, chaired by the Secretary of State for Defence. The Royal Navy operates from three bases in Britain where commissioned ships and submarines are based: Portsmouth, Clyde and Devonport, the last being the largest operational naval base in Western Europe, as well as two naval air stations, RNAS Yeovilton and RNAS Culdrose where maritime aircraft are based.

### Role

As the seaborne branch of HM Armed Forces, the RN has various roles. As it stands today, the RN has stated its six major roles as detailed below in umbrella terms.

* Preventing Conflict – On a global and regional level
* Providing Security At Sea – To ensure the stability of international trade at sea
* International Partnerships – To help cement the relationship with the United Kingdom's allies (such as NATO)
* Maintaining a Readiness To Fight – To protect the United Kingdom's interests across the globe
* Protecting the Economy – To safeguard vital trade routes to guarantee the United Kingdom's and its allies' economic prosperity at sea
* Providing Humanitarian Aid – To deliver a fast and effective response to global catastrophes

## History

The English Royal Navy was formally founded in 1546 by Henry VIII, though the Kingdom of England had possessed less-organised naval forces for centuries prior to this.

The Royal Scots Navy (or Old Scots Navy) had its origins in the Middle Ages until its merger with the English Royal Navy per the Acts of Union 1707.

### Earlier fleets

During much of the medieval period, fleets or "king's ships" were often established or gathered for specific campaigns or actions, and these would disperse afterwards. These were generally merchant ships enlisted into service. Unlike some European states, England did not maintain 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 a time under Edward the Confessor, who frequently commanded fleets in person. After the Norman Conquest, English naval power waned and England suffered 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 navy, this meant the French landed at Sandwich unopposed in April 1216. 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 the French fleet in the Battle of Sluys in 1340. England's naval forces could not prevent frequent raids on the south-coast ports by the French and their allies. Such raids halted only with the occupation of northern France by Henry V. A Scottish fleet existed by the reign of William the Lion. In the early 13th century there was a resurgence of Viking naval power in the region. The Vikings clashed with Scotland over control of 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.

### Age of Sail

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 the Queen's ships in highly profitable raids against Spanish commerce and colonies. The Royal Navy was then used in 1588 to repulse the Spanish Armada, but the English Armada was lost the next year. In 1603, the Union of the Crowns created a personal union between England and Scotland. While the two remained distinct sovereign states for a further century, the two navies increasingly fought as 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 the high church, and expanded it to become the most powerful in the world. The fleet was quickly tested in the First Anglo-Dutch War (1652–1654) and the Anglo-Spanish War (1654–1660), which saw the conquest of Jamaica and successful attacks on Spanish treasure fleets. The 1660 Restoration saw Charles II rename the Royal Navy again, and started use of the prefix HMS. The Navy remained a national institution and not a possession of the Crown as it had been before. 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.

In 1707, the Scottish navy was united with the English Royal Navy. On Scottish men-of-war, 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 the War of the Spanish Succession (1702–1714) granted Britain Gibraltar and Menorca, providing the Navy with Mediterranean bases. The expansion of the Royal Navy would encourage the British colonisation of the Americas, with British (North) America becoming a vital source of timber for the Royal Navy. There was a defeat during the frustrated siege of Cartagena de Indias in 1741. A new French attempt to invade Britain 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 the American War of Independence. The United States was allied to France, and the Netherlands and Spain were also at war with Britain. In the Battle of the Chesapeake, the British fleet failed to lift the French blockade, resulting in the surrender of an entire British army at Yorktown.

The French Revolutionary and Napoleonic Wars (1793–1801, 1803–1814 & 1815) saw the Royal Navy reach 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 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 the Atlantic, and from its base in Bermuda it blockaded the Atlantic seaboard of the United States throughout the war and carried out (with Royal Marines, Colonial Marines, British Army, and Board of Ordnance military corps units) various amphibious operations, most notably the Chesapeake campaign. On the Great Lakes, however, the United States Navy established an advantage.

### Splendid isolation

In 1860 Prince Albert of Saxe-Coburg and Gotha wrote to the Foreign Secretary John Russell, 1st Earl Russell with his concern about "a perfect disgrace to our country, and particularly to the Admiralty". The stated shipbuilding policy of the British monarchy was to take advantage of technological change and so be able to deploy a new weapons system that could defend British interests before other national and imperial resources are reasonably mobilized. Nevertheless, British taxpayers scrutinized progress in modernizing the Royal Navy so as to ensure, that taypayers' money is not wasted.

Between 1815 and 1914, the Navy saw little serious action, owing to the absence of any opponent strong enough to challenge its dominance, though it did not suffer the drastic cutbacks the various military forces underwent in the period of economic austerity that followed the end of the Napoleonic Wars and the American War of 1812 (when the British Army and the Board of Ordnance military corps were cutback, weakening garrisons around the Empire, the Militia became a paper tiger, and the Volunteer Force and Fencible units disbanded, though the Yeomanry was maintained as a back-up to the police). Britain relied, throughout the 19th century and the first half of the 20th century, on imperial fortress colonies (originally Bermuda, Gibraltar, Halifax, Nova Scotia, and Malta, though military control on Nova Scotia passed to the new dominion government after the 1867 Confederation of Canada and naval control of the Halifax Yard was transferred to the new Royal Canadian Navy in 1905) as bases for naval squadrons with stores and dockyard facilities. These allowed control not only of the Atlantic, but it was presumed also of the other oceans. Prior to the 1920s, it was presumed that the only navies that could challenge the Royal Navy belonged to nations on the Atlantic ocean or its connected seas. Britain would rely on Malta, in the Mediterranean Sea, to project power to the Indian Ocean and western Pacific Ocean via the Suez Canal after its completion in 1869 and relying on amity and common interests between Britain and the United States (which controlled transit through the Panama Canal, completed in 1914) during and after the First World War, on Bermuda to project power the length of the Western Atlantic, including the Caribbean Sea and Gulf of Mexico, and eastern Pacific, from the Arctic to the Antarctic – originally, the area controlled from Bermuda (and Halifax until 1905) had been North America, until the 1820s, then absorbed the Jamaica Station to become the North America and West Indies Station, and after the First World War absorbed the eastern Pacific Ocean and the western South Atlantic to become the *America and West Indies Station* until 1956.

During this period, naval warfare underwent 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 the British advantage in ship numbers. In 1889, Parliament passed the Naval Defence Act, which formally adopted the 'two-power standard', which stipulated that the Royal Navy should maintain a number of battleships at least equal to the combined strength of the next two largest navies. The end of the 19th century saw structural changes and older vessels were scrapped or placed into reserve, making funds and manpower available for newer ships. The launch of HMS *Dreadnought* in 1906 rendered all existing battleships obsolete. The transition at this time from coal to fuel-oil for boiler firing would encourage Britain to expand their foothold in former Ottoman territories in the Middle East, especially Iraq.

### Exploration

The Royal Navy played an historic role in several great global explorations of science and discovery. Beginning in the 18th century many great voyages were commissioned often in co-operation with the Royal Society, such as the Northwest Passage expedition of 1741. James Cook led three great voyages, with goals such as discovering Terra Australis, observing the Transit of Venus and searching for the elusive North-West Passage, these voyages are considered to have contributed to world knowledge and science.

In the late 18th century, during a four year voyage Captain George Vancouver made detailed maps of the western coastline of North America. In the 19th century, Charles Darwin made further contributions to science during the second voyage of HMS Beagle. The Ross expedition to the Antarctic made several important discoveries in biology and zoology. Several of the Royal Navy's voyages ended in disaster such as those of Franklin and Scott. Between 1872 and 1876 HMS Challenger undertook the first global marine research expedition, the *Challenger* expedition.

### World War I

During World War I, the Royal Navy's strength was mostly deployed at home in the Grand Fleet, confronting the German High Seas Fleet across the North Sea. Several inconclusive clashes took place between them, chiefly the Battle of Jutland in 1916. The British fighting advantage proved insurmountable, leading the High Seas Fleet to abandon any attempt to challenge British dominance. The Royal Navy under John Jellicoe also tried to avoid combat and remained in port at Scapa Flow for much of the war. This 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 without the loss of a single life at the beginning of the war.

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.

### Interwar period

At 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 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 the Pacific and had begun building large, modern fleets which went to war with each other in 1904. Britain reliance on Malta, via the Suez Canal, as the nearest Imperial fortress was improved, relying on amity and common interests that developed between Britain and the United States during and after World War I, by the completion of the Panama Canal in 1914, allowing the cruisers based in Bermuda to more easily and rapidly reach 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, the Invergordon Mutiny took place in the Atlantic Fleet over the National Government's proposed 25% pay cut, which was eventually reduced to 10%. International tensions increased in the mid-1930s and the re-armament of the Royal Navy was well under way by 1938. In addition to new construction, several existing old battleships, battlecruisers and heavy cruisers were reconstructed, and anti-aircraft weaponry reinforced, while new technologies, such as ASDIC, Huff-Duff and hydrophones, were developed.

### World War II

At 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 the Battle of Britain in order to neutralise the Home Fleet, but faced stiff resistance from the Royal Air Force. The Luftwaffe bombing offensive during the Kanalkampf phase of the battle targeted naval convoys and bases in order to lure large concentrations of RAF fighters into attrition warfare. At Taranto, Admiral Cunningham commanded a fleet that launched the first all-aircraft naval attack in history. The Royal Navy suffered heavy losses in 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 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.

### Cold War

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 the increasing cost of weapons systems.

In 1981, Defence Secretary John Nott had advocated and initiated a series of cutbacks to the Navy. The Falklands War however proved a need for the Royal Navy to regain an expeditionary and littoral capability which, with its resources and structure at the time, would prove difficult. At the beginning of the 1980s, the Royal Navy was a force focused on blue-water anti-submarine warfare. Its purpose 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.

### Post-Cold War

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 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 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 financial costs attached to nuclear deterrence, including Trident missile upgrades and replacements, have become an increasingly significant issue for the navy.
