Royal Navy
The Royal Navy is the official name of the United Kingdom's navy. Its history goes back hundreds of years.
Ark Royal
Napoleonic Wars
The Royal Navy was Britain's principal weapon against Revolutionary France, and France under Napoleon Bonaparte, during the twenty-year conflict between those two nations.
Colonial period
In 1815, after the defeat of Napoleon, the strength of the Royal Navy left Britain the world's pre-eminent naval power.

Driven by First Sea Lord Admiral John Arbuthnot "Jacky" Fisher, the Royal Navy introduced a revolutionary design of battleship that was considered to render all earlier battleships obsolete. The first Royal Navy example of these new battleships was the HMS Dreadnought of 1905. The new vessels were known as 'Dreadnoughts', even if they were built for other navies.
The two differences introduced with this class of vessels was that they were equipped with a large main battery of a single, uniform calibre of large, long range, cannons, and were powered by new, more powerful steam turbine engines, in place of the older technology of triple expansion steam piston engines.
The large main battery of long range cannons of a single calibre enabled engagement with enemy targets at longer range, by firing simultaneous [salvo]]s from the entire battery at one time. The main gunnery officer would sit in a gunnery director in an armoured tower, where they could observe the fall of shot, and tell all the guns in the battery to correct their shared aim.
Germany started building its own fleet of all-big-gun battleships. The two navies were seen to be in a high-profile ship-building arms race.
World War I
During World War I there was only a single full-scale battle between the Royal Navy's fleet of dreadnoughts, and Germany's High Seas Fleet, although there were other important engagements, as well as the emerging submarine threat.
Some commentators describe the Battle of Jutland as indecisive, because both fleets continued to pose a serious threat. Some describe it as a German victory, because the Germans sank more vessels. Some describe it as a British victory, because Britain had control of the seas prior to the battle, and the German fleet remained in port for the duration of the war.
World War I also saw the introduction of the submarine or U-boat, as a commerce raider. The German use of U-boats was countered by the development of convoys, with a convoy escort force armed with depth charges.
Following World War, the United Kingdom, the United States of America, Japan, France and Italy agreed to sign the Washington Naval Treaty capping the tonnage of various classes of warships, in order to prevent another exhausting naval arms race. After a long period of negotiation, the treaty was signed in 1921. The treaty capped the size of battleships at 39,000 tons. Cruisers were capped at 10,000 tons. The treaty allowed the United Kingdom and the USA to have fleets of fifteen battleships. Japan was capped at nine battleships, and the other signatories at six. The size of Germany's navy was capped by the Treaty of Versailles. Germany was allowed "battleships", capped at 10,000 tons - the size of the obsolete pre-dreadnought battleships.
The signatories all basically complied with the treaty, into the 1930s. Germany and Japan are generally regarded as the first nations to covertly subvert the treaty's limits. By the time World War II seemed imminent, all the signatories were quietly ignoring the treaty limits.
World War II
In 1940, at the [[Battle of Taranto],] torpedo-equipped warplanes launched from a Royal Navy aircraft carrier provided the first practical demonstration of the vulnerability of battleships to aerial attack, sinking or damaging much of Italy's fleet.
By World War II, Germany had four battleships, three pocket battleships, and had converted twelve fast freigters into auxiliary cruisers, with hidden guns, that would cruise the world's commercial shipping lanes masquerading as merchant vessels. But the greatest threat the German navy posed was its u-boat fleet. Germany was to build hundreds of u-boats to restrict the vital flow of supplies to Britain. To counter the U-boat wolf packs, the Royal Navy built hundreds of destroyers, and smaller convoy escort vessels such as the Flower Class Corvettes.
Post-World War II
Following World War II, the Royal Navy, like every other navy except the U.S. Navy, retired all its battleships, because the war had shown they were too vulnerable to aerial attack. World War 2 had exhausted the United Kingdom, which allowed almost all of its colonies to become independent. The post-war Royal Navy was now much smaller, no longer trying to match the U.S. Navy in tonnage or number of vessels.
Post-war Royal Navy aircraft carriers were the first to carry vertical take-off fighters, allowing them to carry modern jet aircraft, in a smaller vessel than the big American air craft carriers.
Falklands War
Unexpectedly, in 1983, Argentina invaded the Falkland Islands and South Georgia. At the time, the the Islands' garrison consisted of two Royal Marine platoons. The United Kingdom had just two aircraft carriers at the time of the invasion. The older of the two aircraft carriers had its retirement postponed. Long range Royal Air Force bombers, from Ascension Island, destroyed the Falklands' airfields, preventing Argentina basing fighters there, or resupplying the Falklands by air. A large taskforce proceeded to the Falklands, and allowed ground forces to engage the cut-off Argentine ground forces.
The greatest Argentinian success came through the use of long range Exocet anti-ship cruise missiles. Several vessels were sunk, even when the Exocet's warhead failed to explode, because the missile's rocket engines were hot enough to ignite the vessels' aluminium superstructure. Use of aluminium in construction has since been cut back.
Post-Falklands War
As of 2005 the Royal Navy consisted of 33,154 regular personnel and 988 volunteer reserves, with the Royal Marines having 6,585 personnel. At the same time the fleet strength consisted of the following.
- 4 Vanguard-class strategic missile submarines (Vanguard, Victorious, Vigilant and Vengeance).
- 11 attack submarines comprising 7 Trafalgar-class submarines and 4 Swiftsure class, with 3 Astute-class submarines under construction at that time.
- 3 Invincible-class aircraft carriers (Invincible, Illustrious and Ark Royal).
- 8 destroyers comprising 4 Type 42-class (batch 2) and 4 Type 42 class (batch 3) with an additional 6 D class (Type 45-class) destroyers under construction or projected.
- 18 frigates comprising 4 Broadsword class (Type 22 batch 3) and 14 Duke class (Type 23) vessels.
- 2 Albion class assault ships (Albion and Bulwark).
- 1 or more Amphibious Assault Ship/helicopter carrier (Ocean-class).
- 19 minesweepers/minehunters comprising 11 Hunt class and 8 Sandown class vessels.
The Royal Navy operates many other types of vessel, including small patrol craft, maintenance vessels, survey ships, tankers and training vessels. The bulk of the fleet are situated at Portsmouth, Devonport and Faslane.
After the Cold War
New construction includes the Type 45-class air warfare destroyers, Ocean-class amphibious assault ship/aircraft carriers, and replacements for the current ballistic missile and attack submarines.
RN ships played important roles in the Gulf War and in the Middle East generally.
