HMS Ashanti was a Tribal-class frigate of the Royal Navy, named after the Ashanti people of Ghana. Built by Yarrow in Scotstoun at a cost of £5,315,000, she was notable for being the first commissioned Royal Navy warship equipped with combined steam and gas (COSAG) engines. Launched on 9 March 1959 and commissioned on 23 November 1961, Ashanti represented a significant technological advancement in naval propulsion systems. The vessel's early service was marked by technical challenges, including a failure in her COSAG engines during Caribbean trials in 1962, which led to her return to Britain for repairs. Investigations revealed defects in the COSAG machinery, specifically blade fracturing in the gas turbine, and hull strengthening was also deemed necessary. Despite these setbacks, Ashanti was actively involved in operational deployments, including a 10-month stint in the Persian Gulf and Arabian Sea in 1963, and she also participated in trials of the Westland Wasp helicopter prior to its operational deployment in 1964. Throughout her service, Ashanti engaged in various significant missions. She was part of the Beira Patrol in 1966/67, enforcing sanctions against Rhodesia by preventing oil shipments through Mozambique. During this period, she also underwent a gas turbine refit in Aden amid Britain's withdrawal from the region. In 1969, she embarked a Royal Marines Commando detachment at Bermuda during a Black Power Conference. The frigate also visited the Kuria Muria Islands, Bahrain, and Kuwait, and was involved in the Middle East conflicts, returning to the UK via the Cape of Good Hope in 1967. The vessel's service was marred by tragedies, including two fatalities in 1974 caused by a large wave, and three crew members died in 1977 from carbon monoxide poisoning following a boiler room fire. After a repair and refit in 1978, Ashanti was placed in reserve and used as a Harbour Training Ship. Ultimately, she was sunk as a target in 1988 by submarines Sceptre and Spartan, with her destruction captured during a missile exercise involving Sub Harpoon and torpedoes, breaking the ship in two. Her career reflected the technological evolution and operational versatility of Cold War-era frigates.
