HMS Argonaut (F56) was a Leander-class frigate of the Royal Navy, constructed at the Hawthorn Leslie shipyard in Hebburn, Tyneside, during the mid-1960s. She was launched on 8 February 1966 and commissioned into service on 17 August 1967. The vessel measured approximately 372 feet in length, with a beam of around 41 feet, and displaced roughly 2,500 tons standard load, reflecting typical dimensions of her class. Her design incorporated modern naval technology of the era, including a radar suite that was later upgraded with Exocet missile capability between 1976 and 1980, enhancing her anti-ship armament. Throughout her service, Argonaut participated in diverse operations, including escorting RMS Queen Mary on her final transatlantic voyage in 1967, and joining NATO's Standing Naval Force Atlantic (STANAVFORLANT) in 1968. She was involved in the Beira Patrol in 1969, enforcing sanctions against Rhodesia, and undertook a lengthy, eleven-month global circumnavigation that same year, which included famine relief efforts in Fiji. In 1973, she served as a guard ship at Gibraltar, performing fishery protection duties during the Second Cod War, following Iceland's extension of its fishing limits. Argonaut's operational deployments often included NATO exercises, fishery patrols, and regional security tasks. Notably, she was part of the 'Task Group 317.1' deployment in early 1974, operating in the Barents Sea and visiting Norwegian ports. Her 1981 deployment as part of the Armilla Patrol in the Persian Gulf underscored her strategic importance. Her most significant engagement occurred during the Falklands War in 1982. Arriving at Ascension Island in April, she joined the task force heading toward the Falklands, providing escort and participating in the amphibious landings. On 21 May 1982, during the Battle of San Carlos, Argonaut was attacked by Argentine aircraft, sustaining damage from two bombs—one detonated in her Sea Cat missile magazine, causing casualties and knocking out her power. She was subsequently towed into San Carlos Water for repairs, including defusing the live bombs. Her resilience was demonstrated as she returned to service and participated in the eventual British victory. Post-war, Argonaut continued to serve until her decommissioning on 31 March 1993. She was laid up at Fareham Creek and was eventually broken up in Spain in January 1995. Her service record highlights her versatility, resilience in combat, and strategic role during a pivotal period in maritime history.
