HMS Diomede (F16) was a Leander-class frigate constructed by Yarrow Shipbuilders in Glasgow, launched on 15 April 1969, and commissioned on 2 April 1971. As a member of the Royal Navy, she featured the typical design of the Leander class, which was known for versatility and seaworthiness. During her service, Diomede participated in numerous operational deployments and notable events. In 1972, she was involved in the Second Cod War with Iceland, although her role was relatively subdued. That same year, she joined the 3rd Frigate Squadron based in the Far East, marking her presence in global maritime operations. In 1974, Diomede was part of Task Group 317.2, which caused controversy due to visits to apartheid-era South Africa and military exercises with South African forces. She also visited Brazil for exercises before returning to the UK in 1975. In 1976, she joined the Fishery Protection Squadron and took part in the Third Cod War, during which she collided three times with Icelandic Coast Guard vessels, suffering a significant gash on her port beam. Her notable participation in the Queen Elizabeth II Silver Jubilee Fleet Review in 1977 underscored her prominence within the Royal Navy. During the 1970s, Diomede was also featured as the fictional HMS Hero in the BBC TV series "Warship," with her crew wearing the show's cap tally. Plans for modernization, including the addition of Exocet and Sea Wolf missiles, were canceled in 1981 due to strategic defense reviews; however, the Falklands War in 1982 saw her dispatched to intercept Argentine vessels and escort RFA ships. She also deployed to the Persian Gulf for the Armilla patrol and to the West Indies in 1983, where her crew's performance impressed Queen Elizabeth II, who ordered "splice the mainbrace." In 1987, she returned to patrol near the Falkland Islands and South Georgia. Decommissioned in 1988, Diomede was sold to Pakistan and renamed PNS Shamsheer. She served in the Pakistan Navy until her decommissioning and scrapping in 2003. Her service history reflects her importance as a versatile and active vessel during a transformative period in maritime history.
