HMS Radiant was an R-class destroyer constructed by John I. Thornycroft & Company at Woolston, launched on 25 November 1916. As a member of the Royal Navy during World War I, she was primarily assigned to the 10th Destroyer Flotilla of the Harwich Force from April 1917 until February 1919. The R-class destroyers were designed for high-speed operations, featuring a displacement of approximately 1,000 tons and armed with torpedoes and guns suitable for fleet actions. One notable event in her service occurred on the night of 23 December 1917, when Radiant was escorting a convoy off the coast of Holland. During this operation, she responded to a distress call following the loss of three other destroyers—Torrent, Surprise, and Tornado—after they encountered a German minefield. Torrent struck a mine, and during the rescue attempt, Surprise and Tornado also hit mines, resulting in the loss of 252 officers and men. Radiant successfully rescued twelve survivors from these vessels, demonstrating her role in wartime rescue operations and her resilience in dangerous conditions. After the war, Radiant was briefly part of the 4th Destroyer Flotilla of the Home Fleet before being laid up in reserve under the Nore Command and subsequently sold. In September 1920, she was sold back to Thornycroft and then transferred to the Royal Thai Navy, where she was renamed HTMS Phra Ruang. Her acquisition marked a significant moment in Thai naval history, reportedly financed through personal donations from King Rama VI and other high-ranking officials, making it the first documented private donation for purchasing a warship in Thailand. The Thai Royal Prince Admiral Abhakara Kiartivongse personally negotiated and commanded her voyage from England to Thailand. Throughout her service with the Thai Navy, Phra Ruang remained active beyond World War II, even surviving a torpedo attack in 1943 when USS Trout’s torpedoes proved duds. She was used as a training ship later in her career, was removed from active service in 1957, and officially stricken in 1959. As the last surviving Royal Navy WWI destroyer, her long service history underscores her maritime significance and her role in both British and Thai naval history.
