  • 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 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.

    Triumph was laid down in 1987 by Vickers Shipbuilding and Engineering Limited and launched in February 1991 by Mrs. Ann Hamilton, wife of the then Armed Forces Minister Archie Hamilton.[3] She was commissioned in October that same year. In 2005, Triumph began a £300 million nuclear refuel and refitting period which also saw the installation of an updated 2076 bow, flank and towed array sonar and a new command and control system. The boat rejoined the fleet in June 2010 and is due to be the last of the Trafalgar-class submarines to be decommissioned, scheduled for 2022.[3][4]

    Operational history

    Triumph sailed to Australia in 1993, travelling 41,000 miles (66,000 km) submerged without support—the longest solo deployment so far by a Royal Navy nuclear submarine.[5] In that same year, author Tom Clancy published a book called Submarine: a Guided Tour Inside a Nuclear Warship which was centered around Triumph and USS Miami.

    War in Afghanistan

    After the 9/11 attacks in the USA, Triumph, along with her sister-ship Trafalgar, formed part of a task group in 2001 as part of the American-led invasion of Afghanistan, Britain's contribution being known as Operation Veritas.[5]

    During Operation Veritas, Triumph launched Tomahawk missiles at targets inside Afghanistan. When Triumph returned home after operations had ended, the boat flew the Jolly Roger, the traditional way of denoting live weapons had been fired.[6]

    On 19 November 2000, Triumph ran aground travelling at 22 knots (41 km/h; 25 mph) and at a depth of 200 metres while off the western Scottish coast. The boat surfaced in a safe and controlled fashion. She was under the command of trainee officers and an investigation attributed the grounding to poor navigation. Triumph suffered only superficial damage.[7]

    Triumph was also featured in the TV programme "How to Command a Nuclear Submarine" in 2011 in which trainee commanding officers are shown on the Navy's "Perisher Course".

    Libya Operations

    In March 2011, she participated in Operation Ellamy, firing Tomahawk cruise missiles on 19 March, 20 March and again on 24 March at Libyan air defence targets. One of these strikes hit a command and control centre in Colonel Gaddafi's presidential compound.[3] 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.[8][9][10][11][12][13]

    Eleven weeks later on 20 June upon her return to Devonport, in the interim having deployed for a second deployment in the Mediterranean and relieving HMS Turbulent, she once again flew the Jolly Roger adorned with tomahawks, indicating that further cruise missile strikes had taken place in Libya as part of the ongoing operations there.[14] Analysts believe that in total more than 15 cruise missiles were fired by the submarine during the operations.[15]

    2011/2012 Deployment

    In November 2011, Triumph sailed from her home port in Devonport for a seventh month deployment that will see her away from the UK until summer 2012. The deployment will see her operate in a wide range of locations including the Atlantic, the Mediterranean, the Arabian Sea and the Indian Ocean.[16]


    It was reported in May 2013 that her refit was completed and that she has returned to operational duties.[17]
