The Senior Service: A History of the Royal Navy

Ask a Royal Navy sailor why theirs is called “the Senior Service” and you will usually get a small, satisfied smile before the explanation arrives: the Navy predates the British Army and the Royal Air Force, and it has never let either forget it. That seniority has been earned the hard way, through five hundred years of storms, cannon smoke, mutiny, reform, humiliation and triumph, in roughly that order and often all at once.

This is the story of how a scruffy Tudor coastal defence force became, for a time, the largest and most powerful navy the world had ever seen, and how it has since had to find a smaller, sharper role in a world it no longer runs.

Henry VIII and the Birth of the Navy Royal (1509 to 1547)

England had possessed warships before Henry VIII, but it did not have a navy in any organised sense. When Henry's father, Henry VII, died in 1509, he left his son a modest inheritance of five royal warships.

Henry VIII, a king with a well-documented enthusiasm for showing off, was not going to settle for five of anything.

Over his reign the fleet grew to more than forty ships. He founded dockyards at Woolwich in 1512 and Deptford in 1513, and greatly expanded the dockyard his father had built at Portsmouth, giving the Crown somewhere permanent to build and repair its ships rather than relying on hired merchant vessels whenever a fight broke out.

He also set up the Navy Board to administer this growing fleet, the beginnings of the bureaucratic machinery that would, centuries later, run an empire's worth of shipping.

Henry's dockyards are the part of his legacy that outlasted everything else. Ships rot, burn or get sold for firewood; a dry dock with a basin behind it is still a dry dock four centuries later. The one at Portsmouth had been cut in 1495 for Henry's father, to a design by Sir Reginald Bray, and it remains the oldest surviving dry dock anywhere in the world. What the son added was the machinery around it, and the far more radical idea that the Crown should own its yards outright rather than hire somebody else's whenever a war broke out. The story of what that yard became is in HMNB Portsmouth.

The technical leap forward came with the hinged gunport, which allowed heavy cannon to be mounted low in the hull rather than crammed onto the upper decks, making ships more stable and far better armed. Henry's own flagship, the Mary Rose, was among the first to carry the new low-mounted guns.

She is rather more famous today for sinking in the Solent in 1545, in full view of the King, for reasons still debated by historians (overloading and an ill-timed turn are the leading suspects).

Raised from the seabed in 1982 after 437 years underwater, she now sits in Portsmouth as the best-preserved Tudor warship on Earth, which is one way of getting the last word.

There is a modern coda to her. Before the Mary Rose could be raised she had to be found, and locating a Tudor hull under the silt of the Solent is a survey problem rather than a diving one. The Royal Navy still works that same patch of water: HMS Magpie (H130) has charted the ground the flagship went down on. Four and a half centuries between the two ships, and about a mile of water between where they did their work.

By 1546, Henry had formally established the “Navy Royal”. The name Royal Navy would come later, but the institution, complete with dockyards, standing administration and purpose-built warships, was unmistakably underway.

Gloriana's Navy and the Spanish Armada (1588)

Elizabeth I inherited her father's taste for sea power without his taste for extravagant self-portraiture, and it served her well. English shipwrights of the 1570s, notably at the yards developing faster, lower-built galleons such as the Dreadnought (a name that would echo down the centuries), gave England ships that could out-sail and out-manoeuvre the heavier vessels of Catholic Spain.

That advantage was tested in July and August 1588, when King Philip II of Spain sent an Armada of around 130 ships and 30,000 men to escort an invasion force across the Channel. The English fleet, under Lord Howard of Effingham with Sir Francis Drake as his most celebrated subordinate, harried the Armada up the Channel, then sent fireships into its anchorage off Calais to break up its tight defensive formation.

A running battle off Gravelines followed, after which the scattered Spanish fleet was forced north around Scotland and Ireland to get home, straight into a series of Atlantic storms that did more damage than English guns had managed.

It was not, in truth, a single decisive battle so much as a long, harassing pursuit followed by an act of God, but Elizabethan England was not about to let a good story get bogged down in nuance, and the defeat of the Armada became the founding legend of English sea power.

Worth noting, in the interests of balance and because history rarely lets anyone enjoy an uncomplicated win for long: an English counter-attack the following year, the so-called English Armada of 1589, went rather worse, costing some 40 ships and around 15,000 men. The Navy's early years were a story of both, not just the flattering half.

New Rivals, a New Name (1650s to 1690s)

By the seventeenth century, England's fiercest rival at sea was not Spain but the Dutch Republic, then the dominant trading and naval power in Europe. The Anglo-Dutch Wars, fought in three rounds between 1652 and 1674, were fought increasingly with purpose-built warships rather than converted merchantmen, sharpening naval tactics and ship design on both sides.

English victories at Portland, the Gabbard and Scheveningen in 1653 were matched by a genuinely mortifying Dutch success in 1667, when a raid up the Medway captured or destroyed several English capital ships at anchor, practically within sight of London. It remains one of the more bracing reminders in British naval history that dominance is never guaranteed.

It was in this period, with the restoration of Charles II in 1660, that the fleet officially became “the Royal Navy” and its ships began carrying the “HMS” prefix still used today. The Glorious Revolution of 1688 saw the Navy escort William of Orange's invasion fleet, and by 1692 the decisive Anglo-Dutch victory at Barfleur-La Hogue had ended France's brief bid for naval supremacy.

In 1707, the Act of Union folded the Royal Scots Navy into the Royal Navy, and the fleet that would go on to rule the eighteenth century's oceans was essentially complete in name and structure, if not yet in size.

Georgian Guns and the Year of Miracles (1759)

The eighteenth century was an age of near-constant war between Britain and France, fought as much for colonies and trade routes as for territory in Europe, and the Royal Navy was Britain's principal instrument for winning it. The high point came in 1759, still remembered in some quarters as the “Annus Mirabilis” or Year of Miracles, when British victories piled up on land and sea in quick succession.

The naval crown jewel was the Battle of Quiberon Bay that November, when Admiral Sir Edward Hawke pursued a French fleet into the shallow, rock-strewn waters off the Brittany coast in worsening weather, conditions in which most admirals of the era would have called off the chase and gone home for something warm to drink.

Hawke did not, and the resulting battle scattered and destroyed the French fleet, ending any realistic prospect of a French invasion of Britain and securing British naval dominance for the rest of the Seven Years' War.

It is sometimes called the Trafalgar of its age, which does it a disservice, since Quiberon Bay arguably had the harder job: fighting a proper fleet action in a gale, on a lee shore, at the end of a long autumn day, and winning anyway.

Mutiny at Spithead and the Nore (1797)

Not every Georgian-era story reflects well on the Admiralty, and it would be a disservice to skip the year the Navy nearly stopped working altogether.

In April and May 1797, crews at Spithead mutinied over grievances that had been ignored for decades: pay rates frozen since 1658 despite soaring wartime inflation, food rations shortchanged by the notorious “purser's pound” of fourteen ounces rather than sixteen, and precious little shore leave to compensate.

Admiral Lord Howe negotiated in good faith, secured a royal pardon, a pay rise and the abolition of the short-weight ration, and the affair became known, with typically dry naval understatement, as the “breeze at Spithead”.

A parallel mutiny at the Nore that May went considerably worse. Its leader, Richard Parker, escalated the crews' demands until support collapsed and ships began deserting the cause; when Parker signalled for the fleet to sail for France, nobody followed.

The Nore is worth a closer look, because it was a stranger affair than the word mutiny suggests. It began on 12 May 1797 aboard the 90-gun Sandwich, a tired old three-decker serving as a receiving ship in the Thames estuary, and spread through the anchorage in a matter of days. The crews elected delegates, and the delegates elected a president. Parker was an unusual choice: a former officer who had been disrated, gone bankrupt, and come back to the lower deck as an ordinary seaman, which made him one of the very few men in the anchorage who could draft a formal petition and knew precisely how the Admiralty would read it.

That knowledge did not save him. The Nore demands ran well past Spithead's. More shore leave and a fairer division of prize money were arguable; amendments to the Articles of War, a veto over officers the men would not serve under, and finally a blockade of the Thames itself were not. Closing London's own river in the middle of a war with revolutionary France turned a pay dispute into something a nervous Cabinet could read as the opening move of an English revolution. Ships slipped away one by one through June as the food ran out, and when Sandwich herself came in, Parker was handed over with her. The Navy has never used the word lightly since, as the HMS Iveston (M1151) story shows rather well.

He was convicted of treason and piracy and hanged from the yardarm of his own former flagship.

Twenty-nine more men were hanged after him, and others were imprisoned, flogged or transported to Australia, though most of the many thousands involved were not punished at all.

It is a useful corrective to any suggestion that the Georgian Navy was one long parade of glory: the men who won at Quiberon Bay and would go on to win at Trafalgar were, for a few tense weeks in 1797, on the brink of open rebellion against the conditions they served under.

Nelson and Trafalgar (1805)

No single figure looms larger over Royal Navy history than Horatio Nelson, and no single battle looms larger than Trafalgar. By 1805, Napoleon's ambitions to invade Britain depended on gaining temporary control of the Channel, which in turn depended on defeating the Royal Navy's blockade of the French and Spanish fleets. It did not work out that way.

On 21 October 1805, off Cape Trafalgar on Spain's Atlantic coast, Nelson's 27 ships of the line met a combined Franco-Spanish fleet of 33 under Admiral Villeneuve.

Rather than forming the traditional single line and trading broadsides, Nelson split his fleet into two columns and drove them directly at the enemy line, a tactic bold enough to be dangerous and clever enough to work, banking on superior British gunnery and seamanship to win the close-quarters melee that would follow.

He had written the whole thing down a fortnight beforehand. The memorandum he circulated on 9 October, and talked his captains through over dinner, threw out the orthodoxy of the age. Fleets of that era fought in a single line ahead, parallel to the enemy, which was tidy, controllable and almost always indecisive, since either side could break off the moment the arithmetic stopped suiting them. Nelson proposed to come in at right angles instead and drive through the enemy line at two points, cutting it into three, so that the leading third would be sailing away from a battle it could not quickly rejoin.

The price was a long approach during which his leading ships would be raked from ahead and unable to reply. What he bought with it was what he called a pell-mell battle, a close-range brawl of ship against ship, which was precisely the fight his gunners and seamen were better at than anybody else's. In case the smoke swallowed his signals, he left his captains a rule of thumb that has outlived the memorandum: no captain can do very wrong if he places his ship alongside that of an enemy. It was a plan designed to produce a decisive result rather than a tidy one.

It did: the combined fleet lost some 20 ships captured or destroyed, while Britain lost none.

Nelson himself did not survive to enjoy it. Shot by a French sharpshooter aboard his flagship HMS Victory, he lingered for a few hours below decks, extracting a promise from his flag captain to look after Lady Hamilton, asking to be kissed, and reportedly declaring himself satisfied that he had done his duty before he died.

It is the kind of exit line a scriptwriter would be too embarrassed to invent, and it turned an already formidable naval victory into a national myth. A brutal storm in the battle's aftermath wrecked or recaptured most of the prizes the fleet had taken, so that only four of the captured ships ultimately reached Britain, a reminder that the sea rarely lets a victory go entirely uncontested.

Trafalgar nonetheless secured British naval supremacy for the rest of the Napoleonic Wars and, in practice, for the century that followed.

The ship he died in is still with us, and still, technically, in commission. HMS Victory sits today in that same 1495 dry dock at Portsmouth, the oldest commissioned warship in the world and flagship of the First Sea Lord, which makes her simultaneously a museum piece and an operational appointment.

Ruling the Waves: Pax Britannica (1815 to 1900)

With Napoleon defeated and no serious naval rival left standing, the nineteenth-century Royal Navy settled into the role it is perhaps best remembered for: global policeman of the “Pax Britannica”, the long stretch of relative great-power peace that Britain's naval dominance helped enforce.

The fleet suppressed the transatlantic slave trade, charted the world's coastlines, protected imperial trade routes and, more often than most modern readers appreciate, simply sat at anchor in foreign harbours looking unarguably large.

Technologically, this was the century in which sail gave way to steam and wood gave way to iron and steel, a transition the Navy approached with the mixture of caution and eventual enthusiasm typical of large institutions.

Early experiments with paddle steamers in the 1820s and 1830s proved themselves in the Crimean War of the 1850s, and the launch of HMS Warrior in 1860, an iron-hulled, steam-and-sail-powered battleship, marked the definitive shift away from wooden walls.

Warrior deserves more than a passing mention, because she is that rare thing, a warship that won without ever fighting. Iron-hulled, armoured, faster and better armed than anything afloat, she made every wooden battleship in the world redundant on the day she commissioned. That included the French ironclad Gloire, an armoured ship built on a wooden hull, whose appearance had caused the panic that produced Warrior in the first place. She never fired a shot in anger, and she is afloat at Portsmouth to this day: HMS Warrior (1860).

By 1889, Parliament had formally adopted the “two-power standard”, committing Britain to maintaining a navy at least as strong as the next two largest navies in the world combined, a policy as much about deterrence as vanity. By 1899, the fleet numbered 380 ships in commission with ninety more building, a scale that is difficult to picture from the present day.

The century also brought welcome reform below decks: flogging was abolished in 1879, impressment (the forced conscription of sailors, source of much eighteenth-century misery and more than one American war) gave way to voluntary service, and formal officer training was established aboard the training ship HMS Britannia.

That training ship was an altogether older sort of vessel than Warrior: a wooden three-decker moored in the River Dart, launched as a 121-gun first rate and renamed on her way to becoming a schoolroom. Generations of officers learned their trade aboard her, one of them a future king, and the hulk in the river is where the college at Dartmouth comes from. Her story is in HMS Britannia.

The Navy that entered the twentieth century was, on paper at least, both the most powerful and the most humane version of itself yet.

The Dreadnought Race and the First World War

If any single ship changed naval warfare more than any other, it was HMS Dreadnought, launched in February 1906. She carried a uniform main battery of ten 12-inch guns rather than the mixed armament of earlier battleships, and she was the first capital ship powered by steam turbines, making her faster than anything else afloat.

Dreadnought rendered every existing battleship in the world instantly obsolete, including, somewhat awkwardly, most of the Royal Navy's own fleet, and triggered an international arms race, chiefly with Imperial Germany, that became one of the underlying tensions of the years leading to the First World War.

Every capital ship built afterwards was measured against her; the ones that came before were simply “pre-dreadnoughts”, a category nobody wants to belong to.

The awkwardness cut deeper than it sounds. In a single launch Britain had reduced its own commanding lead in pre-dreadnought battleships to scrap value and reset the count against Germany to something close to parity, which is a peculiar way to defend a naval advantage. Whether Admiral Fisher had been brilliant or reckless is argued over to this day, and her own account is here: HMS Dreadnought (1906).

That arms race produced its great, inconclusive reckoning at the Battle of Jutland on 31 May and 1 June 1916, the only full-scale clash between the British Grand Fleet and the German High Seas Fleet of the entire war. Some 250 ships and around 100,000 men were involved.

Britain lost 14 ships and more than 6,000 men, including the battlecruisers Indefatigable, Queen Mary and Invincible, all three destroyed by catastrophic magazine explosions that killed all but a handful of their crews.

Germany lost 11 ships and over 2,500 men. Tactically it was, at best, a draw, and the British press treated it as a disappointment given the losses involved.

Strategically, though, it settled the matter: the German fleet returned to harbour and never seriously challenged British control of the North Sea again, leaving the Royal Navy free to maintain the blockade that steadily strangled Germany's war effort through to 1918.

Three battlecruisers going the same way in the same afternoon was not bad luck. To keep the guns firing faster, crews had been stacking cordite charges in the turrets and the ammunition hoists and propping the flash doors open, so a single hit anywhere in the turret could send fire straight down the trunk into the magazine. German ships had suffered exactly this at Dogger Bank the year before and had quietly rewritten their handling drills; the Royal Navy had not, and paid for it with three ships and most of three crews inside a couple of hours. Two accounts from the British line that day: the fleet flagship in HMS Iron Duke (1912), and, at the other end of the experience entirely, a dreadnought that fired one salvo in the whole battle in HMS Ajax (1912).

Jutland was the war's headline act, but the more dangerous threat to Britain came from underneath the waves. German U-boats waged an escalating campaign against merchant shipping, and when Germany turned to unrestricted submarine warfare in early 1917, sinking any vessel bound for Britain without warning, the country came uncomfortably close to being starved into submission.

The Admiralty's answer, adopted reluctantly and rather late, was the convoy system: grouping merchant ships together under naval escort instead of sending them out individually as easy targets. It worked, cutting losses dramatically, and it worked well enough that the Royal Navy would reach for exactly the same solution, on a far larger scale, the next time German submarines came hunting in the Atlantic.

The Second World War: The Atlantic, the Bismarck, and D-Day

The Royal Navy's Second World War was fought on several fronts at once, but none mattered more than the Battle of the Atlantic, the six-year struggle to keep Britain's supply lines from North America open against German U-boats. The first convoy sailed within days of the outbreak of war in September 1939, and the campaign did not let up until Germany's defeat in 1945.

It came closest to disaster in 1942 and early 1943, when German U-boat “wolf packs” and gaps in Allied code-breaking combined to inflict devastating losses on merchant shipping. The tide turned by May 1943, through a combination of escort carriers, long-range aircraft, improved radar and codebreaking, and dedicated escort groups, after which Allied shipping losses fell sharply while U-boat losses rose.

Winston Churchill later admitted that the U-boat peril was the only thing that ever really frightened him during the war, which, coming from a man who spent 1940 fully expecting an invasion, is a considerable statement.

The war also produced one of the Navy's most storied single episodes: the hunt for the German battleship Bismarck. On 24 May 1941, Bismarck and the cruiser Prinz Eugen encountered the battlecruiser HMS Hood in the Denmark Strait.

A shell from Bismarck struck near Hood's ammunition magazines; she exploded and sank within about three minutes, taking all but three of her 1,400-plus crew with her.

It was, and remains, one of the worst single losses in Royal Navy history, and it triggered an immediate, fleet-wide manhunt.

The scale of the shock is difficult to convey at this distance. Hood had been the largest warship in the world for twenty years and was, to the British public, the Royal Navy made visible: the ship that had shown the flag around the globe between the wars, and the one warship everybody could name without having to think about it. What actually happened inside her, and why an armoured ship folded in on herself in three minutes, is covered in HMS Hood (51).

Nearly every available British warship was redirected to find Bismarck, which was finally crippled by a torpedo strike from Fleet Air Arm biplanes (elderly Swordfish aircraft that Bismarck's crew could reportedly not believe were being used against them) and sunk on 27 May by a concentration of British battleships and cruisers. Vengeance, in this instance, was thorough.

The two ships that finished the job have their own stories. The Swordfish whose torpedo jammed Bismarck's rudders flew from HMS Ark Royal (91), which would herself be lost to a single torpedo six months later. And the battleship that closed to point-blank range and then did something no battleship has done to another before or since, which was to torpedo her, was HMS Rodney (29).

Three years later, the Navy's job was rather different: not sinking ships, but getting an army safely across the Channel. For the D-Day landings on 6 June 1944, nearly 7,000 vessels took part, most of them under British and Commonwealth control, forming the largest amphibious invasion fleet in history.

Naval forces bombarded German coastal defences, swept invasion lanes clear of mines, and landed over 132,000 troops on the Normandy beaches on the first day alone.

In the weeks that followed, Allied navies moved more than 850,000 personnel, 148,000 vehicles and 570,000 tons of supplies across the Channel, while losing or having damaged around 127 vessels to enemy action. It was unglamorous, largely uncelebrated work compared with the drama of Bismarck or the romance of Trafalgar, and it was also one of the most consequential logistical achievements in the Navy's history.

Retreat from Empire and the Falklands (1945 to 1982)

The postwar decades were, for the Royal Navy, a long and not always graceful exercise in downsizing. Britain's empire dissolved through the 1940s, 50s and 60s, and with it went the strategic justification for a fleet built to police the entire globe.

Successive defence reviews shrank the surface fleet, cancelled new aircraft carriers, and shifted resources towards the nuclear deterrent carried aboard the Navy's submarines, a role it still performs today.

Then, in April 1982, Argentina invaded the Falkland Islands, a British territory in the South Atlantic that most of Whitehall would have struggled to find on a map the week before.

The Royal Navy assembled and despatched a task force with startling speed, built around the carriers HMS Hermes and HMS Invincible, escorted by destroyers, frigates and the submarine HMS Conqueror, which sank the Argentine cruiser General Belgrano on 2 May, the first submarine sinking of a surface warship since the Second World War.

Argentine air attacks took a heavy toll in return: HMS Sheffield was struck and sunk by an Exocet missile on 4 May, and HMS Coventry, HMS Ardent and HMS Antelope were lost in the weeks that followed, alongside the requisitioned container ship Atlantic Conveyor. In total, 255 British servicemen died recovering the islands, a sobering cost for a conflict fought eight thousand miles from home.

Those losses read quickly in a list and rather less quickly from the decks concerned. HMS Sheffield (D80) was the first British warship lost in action since 1945; HMS Ardent (F184) and HMS Antelope (F170) were both lost in San Carlos Water. Not every ship that was hit went down, either: HMS Plymouth (F126) took four bombs in a single afternoon, put out her own fires and sailed home.

The campaign succeeded, and it did something few observers expected of a navy that had spent thirty years being quietly written off: it proved that global reach, however diminished, had not disappeared.

One last thing about that task force, which is easy to miss in the summary: on paper neither of its carriers should have been available at all. HMS Hermes was a twenty-three-year-old ship laid down under an entirely different name and already earmarked for disposal, and HMS Invincible had actually been sold to Australia, the sale cancelled only because of the war. Britain went to the South Atlantic with one carrier bound for the breakers and one that already belonged to somebody else.

The Royal Navy Today

The scale of the shrinkage is worth sitting with for a moment. At the end of the Second World War in August 1945, the Royal Navy had around 990 frigates and larger warships in commission, submarines included: a genuinely staggering number, assembled to fight a war on every ocean at once.

Today its frontline surface escort force consists of eleven ships: six Type 45 destroyers and five Type 23 frigates.

Much of that fall was unavoidable, the by-product of an exhausted postwar economy, a dissolving empire and the sheer fact that missiles and nuclear propulsion made most of the 1945 fleet obsolete almost overnight. Even so, it is a sobering comparison for a service once built on sheer numerical weight.

What today's smaller Navy has traded quantity for is concentrated capability. It continues to carry Britain's nuclear deterrent aboard four Vanguard-class ballistic missile submarines, maintaining an unbroken “Continuous At Sea Deterrent” patrol without a single gap since 1969, a record no other part of the British armed forces can match.

Five Astute-class nuclear attack submarines provide some of the quietest, most capable hunter-killers afloat.

And its most visible modern assets are the two Queen Elizabeth-class aircraft carriers, HMS Queen Elizabeth and HMS Prince of Wales, each displacing around 65,000 tonnes, 284 metres long, and capable of carrying up to 72 aircraft, including up to 36 F-35B stealth fighters, launched via a distinctive ski-jump ramp rather than the catapults used by American carriers.

They are, by a wide margin, the largest warships the Royal Navy has ever operated, a genuinely startling fact for a service that used to measure its fleet in the hundreds of hulls and now measures it rather more carefully in the tonnage of a handful of very expensive ones.

Both have had eventful starts, and both have their own accounts here: HMS Queen Elizabeth (R08), which took her first F-35 landings off the coast of New Jersey before leading a carrier strike group into the South China Sea, and HMS Prince of Wales (R09), whose early career has been a long object lesson in the difference between a setback and a failure.

It is a smaller navy than at any point in its modern history, and a far more specialised one, built around carrier strike groups and nuclear submarines rather than the vast fleets of the Pax Britannica era or the Second World War.

But the throughline from the Mary Rose to HMS Queen Elizabeth is unmistakable: a maritime nation that has, for five hundred years, staked an outsized share of its security, its trade and its self-image on the ships it puts to sea.

The uniforms have changed, the guns have changed almost beyond recognition, and the empire the Navy once guarded is long gone. The habit of going down to the sea in ships, and rather stubbornly refusing to be pushed off it, has not.
