HMS Achilles was a Leander-class frigate of the Royal Navy, built by Yarrow Shipbuilders in Glasgow. She was laid down on December 1, 1967, launched on November 21, 1968, and commissioned on July 11, 1970, with the pennant number F12. The vessel measured 372 feet (113.4 meters) in overall length, with a waterline length of 360 feet (109.7 meters), a beam of 43 feet (13.1 meters), and a maximum draught of 19 feet (5.8 meters). Her displacement was 2,500 long tons (2,540 metric tons) at standard load and approximately 2,962 long tons (3,010 metric tons) at full load. Achilles's propulsion system consisted of two oil-fired boilers powering twin steam turbines, rated at 30,000 shaft horsepower, enabling her to reach speeds of up to 28 knots (about 52 km/h). Armament included a twin 4.5-inch (113 mm) Mark 6 gun mount forward, a Sea Cat surface-to-air missile launcher aft, two Oerlikon 20mm cannons for close defense, and a Limbo anti-submarine mortar. She also featured a helicopter deck and hangar capable of operating a Westland Wasp helicopter, enhancing her anti-submarine capabilities. She was equipped with extensive radar and sonar suites, including Type 965 long-range air search radar, Type 993 short-range radar, Type 978 navigation radar, and sonar systems like Type 184, Type 162, and Type 170. Achilles’s service history included deployments to the Far East, where she escorted larger vessels and participated in various exercises, including the fall of South Vietnam. She was part of the 3rd Frigate Squadron from 1974 and undertook a nine-month deployment to the Far East, visiting African ports en route. Notably, she collided with a Greek tanker in 1975 in the Dover Strait, which resulted in significant damage and repairs until 1976. She also served in the Fishery Protection Squadron during the Third Cod War with Iceland, and was covertly deployed to Belize during the Guatemalan emergency. Throughout her career, Achilles participated in operations in the Persian Gulf, the Falklands post-war patrols, and exercises in the Indian Ocean. She was intended to undergo modernization, potentially replacing her 4.5-inch guns with missile systems, but this was canceled in 1981. She was decommissioned in January 1990, sold to Chile in 1991, and renamed Ministro Zenteno. In 2010, after being washed ashore by a tsunami in Chile, she was ultimately scuttled to prevent navigation hazards.
