In 2014, the Royal Navy website stated that Duncan would be the first Type 45 destroyer to be armed with the Harpoon anti-ship missile system.[16] On 2 March 2015, Duncan left Portsmouth armed with Harpoon anti-ship missiles.[17]


Duncan's construction began at the BAE Systems Naval Ships (now part of BAE Systems Surface Ships) yards at Govan and Scotstoun on the River Clyde in 2006. She was launched from Govan on 11 October 2010,[18] on the 213th anniversary of the Battle of Camperdown.[19]

Duncan sailed from Scotstoun shipyard, Glasgow on 31 August 2012 to commence sea trials.[20]

Operational service

Duncan, the sixth and last Type 45 destroyer, was commissioned on 26 September 2013.[1] She entered service on 30 December 2013, four months ahead of schedule, after a period of trials and training.[21]

On 2 March 2015, Duncan left HMNB Portsmouth on her maiden deployment to the Mediterranean Sea and Middle East.[17] On 7 July 2015, Duncan joined up with the U.S. Navy Carrier Strike Group Twelve to strike the Islamic State of Iraq and the Levant.[22]

In April 2016, HMS Duncan was one of several Royal Navy ships exercising with the French Navy in Exercise Griffin Strike.[23] In October 2016, Duncan, escorted by the frigate HMS Richmond, was dispatched by the Ministry of Defence to intercept and "man-mark" a fleet of Russian Navy vessels, including their flagship Admiral Kuznetsov, which were passing through the English Channel on their way to Syria.[24] In November, while sailing off the coast of England, Duncan suffered a total propulsion failure and was towed back to Plymouth.[25]

Duncan sailed from Portsmouth in June 2017 to assume the role of flagship of NATO's Standing Maritime Naval Group 2 (SNMG2), operating in the Black Sea and the Mediterranean.[26] Duncan was due to be relieved in September 2017 by HMS Ocean on her final deployment,[27] however Ocean was redeployed to the Caribbean Sea to provide relief to British Overseas Territories in the region in the wake of Hurricane Irma. Duncan was instead relieved by HMS Diamond which was berthed in Gibraltar en route to the Persian Gulf to relieve HMS Monmouth.[28] Duncan returned to Portsmouth on 22 September 2017.[29]

She resumed NATO duties in January 2018, visiting Mediterranean and Black Sea ports such as Constanța, Souda Bay, and Split, and again took command of SNMG2, returning to Portsmouth on 13 July 2018. In November and December 2018, Duncan featured on the Channel 5 television documentary Warship: Life at Sea, which captured everyday life on board the vessel during her NATO deployment earlier that year, including confrontations with Russian warships and aircraft. On the programme, it is frequently claimed by the ship's crew that Duncan can detect a 'tennis ball sized object moving at 3-times the speed of sound, from over 100 miles away.' [30][31][32]

In December 2018 it was announced that Duncan would be affiliated with the town of Scarborough on the Yorkshire Coast.[33]

In July 2019 Duncan visited Odessa harbour in Ukraine.[34] On 12 July 2019 she was ordered to the Persian Gulf in response to threats against British shipping by Iran. On arrival she will join with the frigate HMS Montrose in protecting cargo vessels and oil tankers.[35]

Adam Duncan, 1st Viscount Duncan

Adam Duncan, 1st Viscount Duncan (1 July 1731 – 4 August 1804) was a British admiral who defeated the Dutch fleet off Camperdown (north of Haarlem) on 11 October 1797. This victory is considered one of the most significant actions in naval history.

Carrier Strike Group 12

Carrier Strike Group Twelve (CSG-12 or CARSTRKGRU 12) is one of four U.S. Navy carrier strike groups currently assigned to the United States Fleet Forces Command. Carrier strike groups gain and maintain sea control as well as project naval airpower ashore.USS Abraham Lincoln is the aircraft carrier assigned as the strike group's flagship. Units currently assigned to Carrier Strike Group Twelve included Carrier Air Wing One; the Ticonderoga-class cruisers Vicksburg and Normandy; and Destroyer Squadron 2.

Between 2006 and 2011, with USS Enterprise as its flagship, the group made four deployments to the U.S. Fifth Fleet in the Middle East. Strike group aircraft flew over 13,000 air combat missions in support of coalition ground forces in Iraq and Afghanistan, including 2006's Operation Medusa and Operation Mountain Fury in Iraq. The group's surface warships were also involved in several high-profile anti-piracy operations. The group participated in the multilateral exercises Anatolian Sun 2006, Reliant Mermaid 2007, BALTOPS 2008, and Malabar 2015; the bilateral exercise Inspired Union 2006; and the joint exercise Exercise Bold Alligator 2012.

The 2015 deployment was led by its new flagship, USS Theodore Roosevelt, which has since left the group and shifted homeport to Naval Base San Diego, California. Carrier Strike Group Twelve was the first U.S. Navy carrier strike group to deploy with a Naval Integrated Fire Control-Counter Air (NIFC-CA) capability that integrates all units via a data link to gain a more comprehensive overview of its operational battlespace. To augment this NIFC-CA capability, the strike group embarked the new E-2D airborne early warning (AEW) aircraft, making its first overseas deployment.

Guided missile destroyer

A guided-missile destroyer is a destroyer designed to launch guided missiles. Many are also equipped to carry out anti-submarine, anti-air, and anti-surface operations. The NATO standard designation for these vessels is DDG. Nations vary in their use of destroyer D designation in their hull pennant numbering, either prefixing or dropping it altogether. The U.S. Navy has adopted the classification DDG in the American hull classification system.

In addition to the guns, a guided-missile destroyer is usually equipped with two large missile magazines, usually in vertical-launch cells. Some guided-missile destroyers contain powerful radar systems, such as the United States’ Aegis Combat System, and may be adopted for use in an anti-missile or ballistic-missile defense role. This is especially true of navies that no longer operate cruisers, so other vessels must be adopted to fill in the gap.

HMS Daring (D32)

HMS Daring is the lead ship of the Type 45 or Daring-class air-defence destroyers built for the Royal Navy, and the seventh ship to hold that name. She was launched in 2006 on the Clyde and conducted contractor's sea trials during 2007 and 2008. She was handed over to the Royal Navy in December 2008, entered her base port of Portsmouth for the first time in January 2009 and was formally commissioned on 23 July 2009. As the lead ship of the first destroyer class built for the Royal Navy since the Type 42 in the 1970s, she has attracted significant media and public attention. Her name, crest and motto are a reference to the Roman youth Gaius Mucius Scaevola, famed for his bravery.

HMS Dauntless (D33)

HMS Dauntless is the second ship of the Type 45 or Daring-class air-defence destroyers built for the Royal Navy. She was launched at Govan in January 2007, was handed over to the Royal Navy on 3 December 2009 and was formally commissioned on 3 June 2010.

HMS Defender (D36)

HMS Defender is the fifth of the Type 45 or Daring-class air-defence destroyers built for the Royal Navy. She is the eighth ship to bear the name. Construction of Defender began in 2006, and she was launched in 2009. The ship completed her first sea trials in October–November 2011, and was commissioned during March 2013.

HMS Diamond (D34)

HMS Diamond is the third ship of the Type 45 or Daring-class air-defence destroyers built for the Royal Navy. She was launched in 2007, completed her contractor's sea trials in July 2010 and arrived at her base port on 22 September 2010. Diamond was commissioned in a traditional ceremony on 6 May 2011, and formally entered service on 12 July 2011.

HMS Dragon (D35)

HMS Dragon is the fourth ship of the Type 45 or Daring-class air-defence destroyers built for the Royal Navy. She was launched in November 2008 and commissioned on 20 April 2012.

HMS Duncan

Seven Royal Navy ships have been named HMS Duncan, after Admiral Adam Duncan, 1st Viscount Duncan of Camperdown, hero of the Battle of Camperdown.

HMS Duncan (1804) was the mercantile Carron, launched at Bombay Dockyard in 1792. She made three voyages from India to Britain for the British East India Company between 4 November 1795 and 17 June 1801. The Royal Navy purchased her in 1804 for service as a fifth rate and renamed her HMS Dover in 1807. She was wrecked off Madras in 1811.

HMS Duncan (1811) was a 74-gun third-rate launched in 1811, reduced to harbour service in 1826, and broken up 1863.

HMS Duncan (1859) was a 101-gun screw-propelled first-rate launched in 1859, employed on harbour service as HMS Pembroke in 1890, renamed HMS Tenedos in 1905, and sold in 1910.

HMS Duncan (1901), launched in 1901, was a Duncan-class battleship that saw action against German installations on the Belgian coast in World War I and was sold in 1920.

HMS Duncan (D99) was a D-class destroyer, launched in 1932 and scrapped in 1945.

HMS Duncan (F80) was a Type 14 frigate in service from 1957 to 1985.

HMS Duncan (D37) is a Type 45 destroyer launched on 11 October 2010.

HMS Edinburgh (D97)

HMS Edinburgh was a Type 42 (Batch 3) destroyer of the Royal Navy. Edinburgh was built by Cammell Laird of Birkenhead. She was launched on 14 April 1983 and commissioned on 17 December 1985. The largest of the Type 42 destroyers, Edinburgh was known as the "Fortress of the Sea". Edinburgh was the last of the Type 42 destroyer to serve in the Royal Navy and was decommissioned on 6 June 2013.

List of active Royal Navy ships

The Royal Navy is the principal naval warfare service branch of the British Armed Forces. As of November 2018, there are 74 commissioned ships in the Royal Navy. Of the commissioned vessels, twenty two are major surface combatants (six guided missile destroyers, thirteen frigates, two Landing Platform Docks and one aircraft carrier), and ten are nuclear-powered submarines (four ballistic missile submarines and six fleet submarines). In addition the Navy possesses two amphibious transport docks, thirteen mine countermeasures vessels, twenty-two patrol vessels, four survey vessels, one icebreaker and two historic warships, Victory and Bristol, although Bristol is not commissioned so is not in the ship count.

The Royal Navy operates three bases where commissioned ships are based; HMNB Portsmouth, HMNB Devonport and HMNB Clyde. In addition, a number of commissioned vessels belonging to the University Royal Naval Units (URNU) are stationed at various locations around the United Kingdom. The total displacement of the Royal Navy is approximately 407,000 tonnes (641,000 tonnes including the Royal Fleet Auxiliary and Royal Marines).

Besides the Royal Navy, the Royal Fleet Auxiliary and the Royal Marines operate their own flotillas of naval vessels which complement the assets of the Royal Navy, however they are not included in this list or the above figures. In addition, the naval training vessels Brecon and Cromer can be found based at the Royal Navy shore establishment HMS Raleigh and the Britannia Royal Naval College, respectively, along with a number of P1000's and Motor Whalers. As a supporting contingent of Her Majesty's Naval Service, the civilian Marine Services operate a large number of auxiliary ships (including coastal logistics, tugs and research vessels) in support of Royal Navy and Royal Fleet Auxiliary operations.All ships and submarines currently in commission with the Royal Navy were built in the United Kingdom, with the exceptions of icebreaker Protector which was built in Norway and survey vessel Magpie which was substantially built in Ireland. All vessels of the Royal Navy bear the ship prefix "HMS", for Her Majesty's Ship.

Type 45 destroyer

The Type 45 destroyer, also known as the D or Daring class, is a class of six guided missile destroyers built for the United Kingdom's Royal Navy. The class is primarily designed for anti-aircraft and anti-missile warfare and is built around the PAAMS (Sea Viper) air-defence system utilizing the SAMPSON AESA and the S1850M long-range radars. The first three destroyers were assembled by BAE Systems Surface Fleet Solutions from partially prefabricated "blocks" built at different shipyards, the remaining three were built by BAE Systems Maritime – Naval Ships. The first ship in the Daring class, HMS Daring, was launched on 1 February 2006 and commissioned on 23 July 2009.The Type 45 destroyers were built to replace the Type 42 (Sheffield class) destroyers that had served during the Falklands War, with the last Type 42 being decommissioned in 2013. The National Audit Office reported that, during an "intensive attack", a single Type 45 could simultaneously track, engage and destroy more targets than five Type 42 destroyers operating together. After the launch of Daring on 1 February 2006 Admiral Sir Alan West, a former First Sea Lord, stated that it would be the Royal Navy's most capable destroyer ever, as well as the world's best air-defence ship. The reduction in the number to be procured from twelve, then to (up to) eight, finally with only six confirmed (in 2008) was controversial.Another controversy arose when it was revealed that due to a design flaw on the Northrop Grumman intercooler which, when attached to the Rolls-Royce WR-21 gas turbines and functioning in the warm climate of the Persian Gulf power availability was diminished considerably, and it quickly became apparent that the class was not operating as originally envisioned. A refit will take place from 2019-21 to fully resolve the problems with the six ships in the class.
