HMS Duncan (F80), launched in 1957, was a Blackwood-class frigate of the Royal Navy, named after Admiral Adam Duncan. As a Blackwood-class vessel, she was designed primarily for anti-submarine warfare and served during a significant period of Cold War tensions. The ship was commissioned in 1958 and featured a displacement typical of her class, with a length of approximately 230 feet and equipped with sonar and anti-submarine weaponry suited for her role. Her early service saw her as the leader of the Fishery Protection Squadron from 1958 to 1965, where she played a prominent role in the First Cod War between the United Kingdom and Iceland over fishing rights. During this period, she actively intervened between Icelandic coastguard vessels and British trawlers. In August 1960, she served as an escort for the royal yacht Britannia. Her captains included George Cunningham Leslie (1960–1962) and Richard Trowbridge (1962–1964), the latter later becoming a Rear Admiral and Governor of Western Australia. In 1964, HMS Duncan fired a salute at the opening of the new Forth Road Bridge, marking her involvement in notable national events. The same year, she was awarded the Freedom of the City of Hull in recognition of her service during the Cod Wars. A significant refit occurred in 1966 at Rosyth Naval Dockyard, where her sonar and anti-submarine equipment were modernized, after which she mainly conducted anti-submarine training duties. She joined the Londonderry Squadron and later the Portland Training Squadron, participating in Portsmouth Navy Days in 1967 and 1970. A notable crew member was Sir Robin Knox-Johnston, who served aboard her as a watch-keeping and communications officer in early 1968, during his historic single-handed non-stop circumnavigation. HMS Duncan paid off from the Portland Training Squadron in 1971 and later served as a harbor training ship at Rosyth in the early 1980s, supporting marine engineering apprentices from HMS Caledonia. Her service history reflects her importance in Cold War naval operations, maritime training, and national ceremonies.
