The Royal Navy is an English-then-British state institution whose popular statue is Horatio Nelson at Trafalgar (21 October 1805) and whose industrial truth is coal, then oil, then a 1914 dreadnought race and a 1939-45 convoy war. Samuel Pepys is the Restoration administrative name; John Fisher is the 1900s reform name (Dreadnought, 1906); Jellicoe and Beatty split Jutland (31 May-1 June 1916) into a century of argument. This page is force-structure history -- manning, yards, doctrine as dated debate -- not a live order of battle and not a how-to for any ship.
Political impact is high because the fleet was the hardware of a global empire and then of a declining great power that chose the US alliance. The two Atlantic U-boat crises (1917, 1940-43) recast the RN as an escort-and-air navy as much as a battle-line navy. Andrew Cunningham's Mediterranean 1940-43 is the other English still. Intensity is mid-atlas: an institution, not a single battle's peak.
Korean contact is real and under-taught in London: UN naval operations in 1950-53, including British light carriers HMS Theseus and Glory and a minesweeping story. William Andrewes is a named RN figure in that war. Tsushima (1905) is a Japanese-Russian file the RN watched as a student of gunnery -- see that battle page. This is not a current ROKN-RN ORBAT.

Deep introduction
A battle line that became a convoy and an alliance
The RN's honest twentieth-century sentence is not Trafalgar repeated; it is yards, oil, escorts, and a handoff of maritime primacy.
Tudor to Nelson
A standing navy, press gangs, and a 1756-1815 near-continuous war with France. Trafalgar froze the popular image. Pepys froze the administrative one.
No sail-handling lesson.
Fisher to Jutland
Dreadnought (1906) and the German race. Jutland as a tactical draw and a strategic hold -- the argument English memoirs never ended.
No gunnery table.
Two Atlantics
1917 and 1939-43 made convoy, air, and intelligence the surviving arts. See the submarine page for the opponent type.
Western Approaches is a place and a system -- history, not a present ASW manual.
Alliance navy
1945-present shrinkage, the US special relationship at sea, Korea 1950-53 as a UN footnote, and later carriers as political objects. History of a smaller fleet, not a current list of hulls.
Alliance navy stays dated: 1916-05-31 (Jutland) in Home waters, the Atlantic, the Mediterranean, and a global imperial-then-alliance map. John Jellicoe, 1st Earl Jellicoe (Admiral) is a named witness -- Jutland's Grand Fleet commander -- the cautious name in the English split. Cost band: not one war -- an institution; human cost sits in the wars the fleet fought. Encyclopedia, not a method.
The long British institution that Trafalgar mythologised and the Atlantic industrialised.

Key terms
Senior Service
British nickname -- a cultural fact.
Dreadnought
1906 type that reset a race -- a political ship.
Western Approaches
The 1939-45 convoy-command geography.

Press gang
Manning violence of the sailing navy -- part of the cost file.
HMS Theseus / Glory

Image vs oil
Nelson is the statue. Fisher and tanker routes are the twentieth-century truth.
A statue that hides oil is a children's book.
Jutland argument
Jellicoe vs Beatty is an English civil religion of 1916.
The strategic fact (blockade held) sits beside the tactical disappointment.
Korea footnote
A real UN naval war that London under-teaches beside Imjin.
Andrewes and the light carriers belong in the paragraph.

Frequently asked questions
Are the scores a ranking of nations or armies?
No. Scores are browsing aids inside an era-bounded atlas — not live league tables of countries.
Why Trafalgar?
21 October 1805 ended a combined Franco-Spanish battle fleet as a threat in that war and killed Nelson into a civic religion. It did not freeze naval history.
What was Jutland?
The 31 May-1 June 1916 North Sea clash. Tactically disappointing for British hopes; the blockade continued. Memoirs split Jellicoe and Beatty for a century.
How did U-boats change the RN?
In 1917 and again in 1940-43 they made escort, air, and convoy the surviving problem. See the submarine page.
Did the RN fight in Korea?
Yes -- UN naval operations, including British light carriers and minesweeping. Thinner in UK public memory than the Glorious Glosters' Imjin story.
Is this a current fleet list?
No. Era-bounded force-structure history. No live hull list, no patrol tracker.
How does Tsushima relate?
The RN studied 1905 as a gunnery and Togo story. The battle is Japanese-Russian -- see that page.
