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 (as of 2023) 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 The Trafalgar class has nearly been replaced by the larger and more capable Astute class, of which five are commissioned.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 name Trafalgar refers to the Battle of Trafalgar fought between the Royal Navy and the combined fleets of France and Spain in 1805.
The Trafalgar class were designed in the early 1970s during the Cold War as a refinement of the preceding Swiftsure class. Including HMS Dreadnought, the Trafalgar class are the fifth class of nuclear-powered fleet submarines to enter service with the Royal Navy. The first of the class, HMS Trafalgar, was ordered on 7 April 1977 and completed in 1983. The last, HMS Triumph, was ordered on 3 January 1986 and completed in 1991. All seven boats of the class were built and completed by Vickers Shipbuilding and Engineering at the Barrow-in-Furness shipyard.
In 1982, Jane's Fighting Ships recorded: "Estimated cost of fourth submarine £175 million including equipment and weapon system when fitted." In 1986, Jane's Fighting Ships recorded that the average cost for this class was £200 million at 1984–85 prices. [4]
In 1987, the Canadian White Paper on Defence recommended the purchase of 10 to 12 Rubis- or Trafalgar-class submarines under technology transfer, [5] with the choice of the type of submarine due to be confirmed before summer 1988. [6] The goal was to build up a three-ocean navy and to assert Canadian sovereignty over Arctic waters. [7] The purchase was finally abandoned in April 1989 due to the financial economy. In 1998 the Canadian government signed an agreement to acquire four of the Royal Navy's diesel-electric Upholder-class submarines.
The submarines of the class have seen service in a wide range of locations, most notably firing Tomahawk land-attack cruise missiles in anger at targets during conflicts in Afghanistan, Iraq and Libya. Three of the Trafalgar-class boats have been involved in such operations. In 2001 Trafalgar took part in Operation Veritas, the attack on Al-Qaeda and Taliban forces following the September 11 attacks in the United States, becoming the first Royal Navy submarine to launch Tomahawk cruise missiles against Afghanistan. [8] During April 2003, HMS Turbulent returned home flying the Jolly Roger after having launched thirty Tomahawk cruise missiles during the invasion of Iraq. [9] As part of the 2011 military intervention in Libya, HMS Triumph fired her Tomahawk cruise missiles on three occasions; first on 19 March, [10] then again on 20 March, [11] [12] and finally on 24 March. [13] Her primary targets were Libyan air-defence installations around the city of Sabha. [14] Triumph returned to Devonport on 3 April 2011 flying a Jolly Roger adorned with six small Tomahawk axes to indicate the missiles fired by the submarine in the operation. [15]
In 1993 Triumph sailed to Australia, covering a distance of 41,000 miles (66,000 km) whilst submerged and without any forward support. As of 2011, this still remained the longest solo deployment by any British nuclear submarine. [16]
In 1998, Trenchant experienced a steam leak, forcing the crew to shut down the nuclear reactor. In 2000 a leak in the PWR1 reactor primary cooling circuit was discovered on Tireless, forcing her to proceed to Gibraltar on diesel power. [17] The fault was found to be due to thermal fatigue cracks, requiring the other Trafalgar-class boats, and some of the remaining Swiftsure-class boats, to be urgently inspected and if necessary modified. [17]
In 2013 the Defence Nuclear Safety Regulator reported that the reactor systems were suffering increasing technical problems due to ageing, requiring effective management. An example was that Tireless had had a small radioactive coolant leak for eight days in February 2013. [18]
As a refinement of the preceding Swiftsure class, the design of the Trafalgar class bears some similarity, including its internal layout and the Rolls-Royce PWR1 Core 3. However some improvements over the Swiftsure class include its reduced acoustic signature, which is due to the hull being covered in anechoic tiles which are designed to absorb sound rather than reflect it, making the boats quieter and more difficult to detect with active sonar. A pumpjet propulsion system is also used from boat 2 onward, rather than a conventional propeller. [19] The Trafalgar class are 85.4 m (280 ft 2 in) long, [2] have a beam of 9.8 m (32 ft 2 in), [2] a draught of 9.5 m (31 ft 2 in) [2] and a dived displacement of 5,300 tonnes (5,200 long tons ). [2] Each boat has a complement of 130. [2] Like all Royal Navy submarines, the Trafalgar class have strengthened fins and retractable hydroplanes, allowing them to surface through thick ice.
Four boats of the class — Torbay, Trenchant, Talent and Triumph — have been fitted with the Sonar 2076 system. Beginning in 2014, the last four boats of the class underwent a communications package upgrade. [2]
The Trafalgar class is equipped with five 21-inch (533 mm) torpedo tubes with accommodation for a mixture of up to 30 weapons: [2]
The Tomahawk missiles are capable of hitting a target to within a few metres, to a range of 1,000 miles (1,600 km). [20]
Ostensibly, the submarines use the same steering column as was used in the Wellington bombers of the Second World War. [21]
Initially, the last five boats of the Trafalgar class were to be replaced by the 'Future Fleet Submarine' programme, however this was effectively cancelled in 2001. The Astute class are replacing the Trafalgar class. [22]
Triumph is the only remaining submarine based at HMNB Devonport. [23] Talent and Trenchant were decommissioned in a joint ceremony at HMNB Devonport on 20 May 2022. [24] [25]

In June 2019, ITV commissioned a six-part thriller to be set aboard a fictional Trafalgar-class submarine, HMS Tenacity. [31] However, production on the series was paused in 2020, before being dropped all together by November 2021. [32]
The Swiftsure class was a class of nuclear-powered fleet submarines in service with the Royal Navy from the early 1970s until 2010.
HMS Astute is an operational nuclear-powered attack submarine in the Royal Navy, the lead boat of her class.
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 Queen Camilla, 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 Splendid was a Royal Navy nuclear-powered fleet submarine of the Swiftsure class. From commissioning in 1979 to her decommission in 2004 she took part in many operations involving British forces around the globe.
HMS Triumph is a Trafalgar-class nuclear submarine of the Royal Navy and was the seventh and final boat of her class. She is the nineteenth nuclear-powered hunter-killer submarine built for the Royal Navy. Triumph is the tenth vessel, and the second submarine, to bear the name. The first HMS Triumph was a 68-gun galleon built in 1561. As of 2022, she is the last boat of her class remaining in service.
HMS Trafalgar is a decommissioned Trafalgar-class submarine of the Royal Navy. Unlike the rest of the Trafalgar-class boats that followed, she was not launched with a pump-jet propulsion system, but with a conventional 7-bladed propeller. Trafalgar was the fifth vessel of the Royal Navy to bear the name, after the 1805 Battle of Trafalgar.
HMS Turbulent is a retired Trafalgar-class submarine of the Royal Navy and the second vessel of her class. Turbulent was the fifth vessel, and second submarine, of the Royal Navy to bear this name. She was built by Vickers Shipbuilding, Barrow-in-Furness, and based at HMNB Devonport. She was commissioned in 1984 and decommissioned in July 2012. She was stripped of equipment and now awaits dismantling in number 3 Basin at Devonport.
HMS Tireless was the third Trafalgar-class nuclear submarine of the Royal Navy. Tireless is the second submarine of the Royal Navy to bear this name. Launched in March 1984, Tireless was sponsored by Sue Squires, wife of Admiral 'Tubby' Squires, and commissioned in October 1985.
HMS Trenchant was a Trafalgar-class nuclear-powered fleet submarine of the Royal Navy built by Vickers Shipbuilding, Barrow-in-Furness. Trenchant was based at HMNB Devonport. She was the third vessel and the second submarine of the Royal Navy to be named for the characteristic of vigour and incisiveness.
HMS Talent is the sixth of seven Trafalgar-class nuclear submarines operated by the Royal Navy from 1990 until 2022. It was built at Barrow-in-Furness.
HMS Superb was a nuclear-powered fleet submarine of the Swiftsure class serving in the Royal Navy.
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 Commander-in-Chief Fleet (CINCFLEET) was the admiral responsible for the operations of the ships, submarines and aircraft of the British Royal Navy from 1971 until April 2012. The post was subordinate to the First Sea Lord, the professional head of the Naval Service. In its last years, as the Navy shrank, more administrative responsibilities were added.
His Majesty's Naval Base, Clyde, primarily sited at Faslane on the Gare Loch, is one of three operating bases in the United Kingdom for the Royal Navy. It is the navy's headquarters in Scotland and is best known as the home of Britain's nuclear weapons, in the form of nuclear submarines armed with Trident missiles.
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.
HMS Agincourt is an Astute-class nuclear-powered fleet submarine under construction for the Royal Navy and the seventh in her class. The boat's name was confirmed in May 2018, having previously held the in-work name of Ajax.
Operation Ellamy was the codename for the United Kingdom participation in the 2011 military intervention in Libya. The operation was part of an international coalition aimed at enforcing a Libyan no-fly zone in accordance with the United Nations Security Council Resolution 1973 which stipulated that "all necessary measures" shall be taken to protect civilians. The coalition operation was designated by NATO as Operation Unified Protector, by the US as Operation Odyssey Dawn. The Canadian participation as Operation Mobile and the French participation as Opération Harmattan. It was confirmed in December 2011 that the cost of the operations was £212m – less than was estimated, including £67m for replacing spent munitions, is all expected to be met from the Treasury reserve.
In 1989 the Royal Navy was under the direction of the Navy Department in the UK Ministry of Defence. It had two main commands, CINCFLEET and Naval Home Command.
