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 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 three boats in commission and four retired, the class makes up half of the Royal Navy's nuclear-powered ‘hunter-killer’ submarine force. The Trafalgar class is being gradually replaced by the larger and more capable Astute class, of which three are complete. The name Trafalgar refers to the Battle of Trafalgar fought between the Royal Navy and the combined fleets of France and Spain in 1805.
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 includes four boats: 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 Astute class is the latest class of nuclear-powered fleet submarines (SSNs) in service with the Royal Navy. The class sets a new standard for the Royal Navy in terms of weapons load, communication facilities and stealth. The boats are being constructed by BAE Systems Maritime – 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.
HMS Talent is the sixth of seven Trafalgar-class nuclear submarines of the Royal Navy, and was built at Barrow-in-Furness. Talent was launched by The Princess Royal in April 1988 and commissioned in May 1990. The boat is affiliated with Shrewsbury in Shropshire. Talent is the third submarine of the Royal Navy to bear the name. The first was the World War II Talent, a T-class submarine transferred to the Royal Netherlands Navy as RNLMS Zwaardvisch in 1943.
HMS Artful is the third Astute-class nuclear-powered fleet submarine of the British Royal Navy. She is the second submarine of the Royal Navy to bear this name. Artful was ordered from GEC's Marconi Marine on 17 March 1997, and was constructed at Barrow in Furness. She was named on 20 September 2013, was rolled out of the shipyard construction hall on 16 May 2014, and was due to start sea trials in early 2015. Artful made her first successful basin dive in October 2014, and sailed on 13 August 2015 for sea trials. Artful was handed over the Royal Navy on 14 December 2015, and commissioned on 18 March 2016.
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 British nuclear submarines since the Valiant class, commissioned in 1966. The first British nuclear submarine, HMS Dreadnought, was powered by a Westinghouse S5W reactor.
A nuclear submarine is a submarine powered by a nuclear reactor. The performance advantages of nuclear submarines over "conventional" submarines are considerable. 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 of time; and the long interval between refuelings grants a range virtually unlimited, making the only limits on voyage times being imposed by such factors 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 theory she is replaced by the first Astute-class submarine in service, HMS Astute.
The eleventh HMS Vanguard of the Royal Navy is the lead boat of her class of Trident ballistic missile-armed submarines. The submarine is based at Faslane, HMNB Clyde, Argyll, Scotland.
The latest HMS Warspite was the third of Britain's nuclear-powered submarines, and the second of the Valiant class. After entering service in 1967 she collided with a Soviet submarine the following year. A mechanical failure associated with the submarine's nuclear reactor in 1991 led to the boat being laid up at HMNB Devonport where she awaits disposal.
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.
HMSVictorious is the second Vanguard-class submarine of the Royal Navy. Victorious carries the Trident ballistic missile, the UK's nuclear deterrent.
HMS Vengeance is the fourth and final Vanguard-class submarine of the Royal Navy. Vengeance carries the Trident ballistic missile, the UK's nuclear deterrent.
BAE Systems Submarines, known as BAE Systems Submarine Solutions until January 2012 and then BAE Systems Maritime - Submarines until 2017, 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 the submarines are generally required to operate undetected.
Scotland has a long history of nuclear research and electricity generation. Nuclear energy accounted for 42.8% of electricity generated in Scotland in 2016.
