Pre-First World War
This is a list of Royal Navy submarines, arranged chronologically. Submarines that are currently active and commissioned are shown below in bold.
From HMS Porpoise Royal Navy submarines were given their own "S" pennant numbers.

The Swiftsure class was a class of nuclear-powered fleet submarines in service with the Royal Navy from the early 1970s until 2010.
The Trafalgar class is a class of nuclear-powered fleet submarines (SSNs) in service with the Royal Navy, and the successor to the Swiftsure class. Like the majority of Royal Navy nuclear submarines, all seven boats were constructed at Barrow-in-Furness shipyard, Cumbria. With only one boat remaining active and in commission and six retired from the seven originally in service, the class makes up part of the Royal Navy's nuclear-powered ‘hunter-killer’ submarine force. The Trafalgar class has nearly been replaced by the larger and more capable Astute class, of which five are commissioned.
The Vanguard class is a class of nuclear-powered ballistic missile submarines (SSBNs) in service with the Royal Navy. The class was introduced in 1994 as part of the Trident nuclear programme, and comprises four vessels: Vanguard, Victorious, Vigilant and Vengeance, built between 1986 and 1999 at Barrow-in-Furness by Vickers Shipbuilding and Engineering, now owned by BAE Systems. All four boats are based at HM Naval Base Clyde , 40 km (25 mi) west of Glasgow, Scotland.
The Amphion class of British diesel-electric submarines were designed for use in the Pacific War. Only two were completed before the end of hostilities, but following modernisation in the 1950s, they continued to serve in the Royal Navy into the 1970s.
The Astute class is the latest class of nuclear-powered fleet submarines (SSNs) in service with the Royal Navy. The boats are being constructed by BAE Systems Submarines at Barrow-in-Furness. Seven boats will be constructed: the first of class, Astute, was launched by Camilla, Duchess of Cornwall, in 2007, commissioned in 2010, and declared fully operational in May 2014. The Astute class is the replacement for the Trafalgar-class fleet submarines in Royal Navy service.
An attack submarine or hunter-killer submarine is a submarine specifically designed for the purpose of attacking and sinking other submarines, surface combatants and merchant vessels. In the Soviet and Russian navies they were and are called "multi-purpose submarines". They are also used to protect friendly surface combatants and missile submarines. Some attack subs are also armed with cruise missiles, increasing the scope of their potential missions to include land targets.
The seventh HMS Dreadnought was the United Kingdom's first nuclear-powered submarine, built by Vickers Armstrongs at Barrow-in-Furness. Launched by Queen Elizabeth II on Trafalgar Day 1960 and commissioned into service with the Royal Navy in April 1963, she continued in service until 1980. The submarine was powered by a S5W reactor, a design made available as a direct result of the 1958 US–UK Mutual Defence Agreement.
The Valiant class were a class of nuclear-powered fleet submarines in service with the Royal Navy from the mid-1960s until 1994. They were the first fully British nuclear fleet submarine; the earlier HMS Dreadnought used an American nuclear reactor. There were only two boats in the class, the first, Valiant commissioned in 1966 three years after Dreadnought, and Warspite the following year. Both were built by Vickers at Barrow-in-Furness.
The Rolls-Royce pressurised water reactor (PWR) series has powered the Royal Navy's nuclear submarines since the Valiant class, commissioned in 1966.
A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. Nuclear submarines have considerable performance advantages over "conventional" submarines. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines. The large amount of power generated by a nuclear reactor allows nuclear submarines to operate at high speed for long periods, and the long interval between refuelings grants a virtually unlimited range, making the only limits on voyage times being factors such as the need to restock food or other consumables.
The fifth HMS Sceptre is a Swiftsure-class submarine built by Vickers in Barrow-in-Furness. She was launched in 1976, with a bottle of cider against her hull. She was commissioned on 14 February 1978, by Lady Audrey White. She was the tenth nuclear fleet submarine to enter service with the Royal Navy. She was decommissioned on 10 December 2010, at which time she was the oldest commissioned vessel in the Royal Navy still available for service; in total around 1,500 men served aboard during her commission. In theory, she is replaced by the first Astute-class submarine in service, HMS Astute.
An SSN is a nuclear-powered general-purpose attack submarine. SSN is the US Navy hull classification symbol for such vessels; the SS denotes a submarine and the N denotes nuclear power. The designation SSN is used for interoperability throughout NATO under STANAG 1166, though navies use other terms.
BAE Systems Submarines, is a wholly owned subsidiary of BAE Systems, based in Barrow-in-Furness, Cumbria, England, and is responsible for the development and production of submarines.
The Royal Navy Submarine Service is one of the five fighting arms of the Royal Navy. It is sometimes known as the Silent Service, as submarines are generally required to operate undetected.
The Dreadnought class is the future replacement for the Royal Navy's Vanguard class of ballistic missile submarines. Like their predecessors they will carry Trident II D-5 missiles. The Vanguard submarines entered service in the United Kingdom in the 1990s with an intended service life of 25 years. Their replacement is necessary for maintaining a continuous at-sea deterrent (CASD), the principle of operation behind the Trident system.
Keith Foulger was a British naval architect. As a child he aspired to a career as a Royal Navy officer but failed the eyesight requirements and so started a career in naval architecture. Foulger joined the Royal Corps of Naval Constructors and worked on designs for the Porpoise and Explorer-class submarines. Following the 1958 US–UK Mutual Defence Agreement Foulger was chosen to lead a team to observe the construction of the Skipjack-class submarine being constructed for the US Navy. The first British nuclear submarine HMS Dreadnought would use the same reactor and so the aft portion had to accommodate that design. Foulger's job was to minimise any mismatch between this portion and the forward section which was to be a wholly British design.
Vulcan Naval Reactor Test Establishment (NRTE), formerly HMS Vulcan, is a UK Ministry of Defence (MoD) establishment in Scotland, operated by Rolls-Royce Submarines.
