HMS Plymouth (F126) was a Royal Navy Rothesay-class frigate, constructed at Devonport Dockyard, with her keel laid on 1 July 1958. Launched by Viscountess Astor on 20 July 1959, she was commissioned on 11 May 1961, serving as a versatile anti-submarine and fleet escort vessel. The ship measured 370 feet in length overall, with a beam of 41 feet and a draught of 13 feet 6 inches. Powered by Y-100 machinery, she featured two Babcock & Wilcox water-tube boilers feeding two sets of geared steam turbines rated at 30,000 shaft horsepower, enabling her to reach speeds of approximately 29.5 knots. Her crew comprised about 212 officers and men. Her armament initially included a twin 4.5-inch Mark 6 gun mount forward, with a single 40 mm Bofors as a temporary aft anti-aircraft weapon, later replaced by Seacat missile launchers following modernization. The ship was equipped with a comprehensive radar suite, including Type 293Q surface/air search radar and Type 277 height-finding radar, alongside sonar systems for anti-submarine warfare. Originally armed with twelve 21-inch torpedo tubes and Limbo mortars, the torpedo tubes were soon removed due to their ineffectiveness against modern submarines. Between 1966 and 1969, HMS Plymouth underwent extensive modernization, adding a hangar and flight deck for a Westland Wasp helicopter, a Seacat missile system, and updated radar and fire control systems, bringing her capabilities closer to the Leander class. Her service record included leading escort squadrons in Singapore and Australia, participation in the Beira Patrol, and involvement in the Cod Wars. HMS Plymouth played a prominent role during the Falklands War in 1982, being among the first ships to arrive in the South Atlantic. She participated in the recapture of South Georgia, supporting landings and engaging Argentine vessels, including attacking the submarine Santa Fe. During the conflict, she sustained damage from Argentine air attacks, notably bombs dropped by Dagger fighters, which caused extensive internal damage but did not explode. She fired over 900 shells and nine Seacat missiles during the conflict before returning to the UK for repairs. Decommissioned on 28 April 1988, HMS Plymouth was preserved as a museum ship, first in Glasgow and later in Birkenhead. Despite efforts to save her, she was sold for scrapping in 2014 and dismantled in Turkey. Her service history highlights her as a significant vessel in Cold War and Falklands conflict maritime history.
