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.
Dragons construction began at the then BAE Systems Naval Ships (later BAE Systems Surface Fleet Solutions) yard at Scotstoun on the River Clyde in December 2005, and by December 2007 the bow section was in place on the Govan slipway for mating with the other modules. Dragon launched from the slipway at Govan on 17 November 2008 at 3:00 pm. Her sponsor was Mrs Susie Boissier, wife of Vice Admiral Paul Boissier, Deputy Commander-in-Chief Fleet and Chief of Staff. The ship was fitted out at Scotstoun.
Dragon commenced her first set of contractor's sea trials on 5 November 2010.
Dragon entered her home port of Portsmouth for the first time on 31 August 2011.
Dragon joined the Royal Navy Surface Fleet on Friday, 20 April 2012. On Friday 27 April, she made her maiden visit to Liverpool, staying for three days. She opened to the public on Saturday 28 April, with visitors able to see the inside of the ship, including the operations room.
In August 2013, it was reported Dragon was sailing with the carrier group in the Arabian Sea, acting as the main point ship for aircraft control. In August 2013, several Typhoons from No. 6 Squadron RAF were exercising with Dragon and US fighters in the Persian Gulf. It sailed westward to the Eastern Mediterranean.
In April 2014, Dragon was deployed to waters north of Scotland, after sailing from Portsmouth to track the Russian warship . She was part of the Royal Navy's Atlantic Patrol Tasking in late 2014, visiting places such as the South Georgia Islands, the Falkland Islands, and a transit through the Panama Canal.
In October 2016, Dragon tracked two Russian corvettes in the Atlantic Ocean and Bay of Biscay during a major deployment of Russian naval forces near the United Kingdom.
On 11 February 2017, Dragon rescued the fourteen crew of the dismasted and adrift British yacht Clyde Challenger in the Atlantic Ocean south west of Land's End, Cornwall. Clyde Challenger was subsequently scuttled.
A 26 November 2018 press-release claimed Dragon discovered a suspicious boat while on operation in the Middle East. Sailors and Royal Marines boarded the vessel, and found 148 bags containing 3,048 kg of hashish.
On 15 March 2019, Dragon made its seventh drug seizure, involving 224kg of heroin from a fishing vessel in the Arabian Sea. During her time in the Arabian Sea, Dragon made eight drug busts and seized over eighteen tons of narcotics, a record for the number of successful busts and the total weight of drugs seized by a Royal Navy ship in the Middle East.
As of March 2019, took over the Dragon patrol role in the Persian Gulf.
HMS Dragon set sail in May 2025 to take part in NATO's Formidable Shield; the largest at-sea live-fire exercise in Europe.
On 3 March 2026, Prime Minister Keir Starmer announced that HMS Dragon would be deployed to the eastern Mediterranean to reinforce security around RAF Akrotiri in Cyprus. The deployment followed a Shahed-136 drone strike shortly after midnight on 2 March 2026 that caused minor damage to a hangar during the Iran war. Accompanied by three Wildcat helicopters, armed with Martlet missiles, and a Merlin helicopter that were airlifted separately, the destroyer was tasked with strengthening air defences against drone threats. HMS Dragon departed Portsmouth for Cyprus on 10 March 2026 after rapid preparations following a period in dry dock, with the crew recalled and the usual six weeks of maintenance, weapons loading, and system checks completed in six days.
At launch Dragon displayed a red Welsh Dragon on each side of her bow, the only Royal Navy ship to be adorned in this way. The dragons, which had been privately funded, were removed in a 2011 refit and repaint, and restored in 2016, funded by a campaign led by the British Warships Association.
Dragon appeared in No Time to Die, the 25th film of the James Bond series. The film inaccurately depicts the Type 45's Aster Surface-to-Air missiles as land attack missiles. Shooting for Dragon role in the film's finale took place off the Faroe Islands in September 2019.
