HMS Berwick was a Rothesay-class (Type 12M) anti-submarine frigate of the British Royal Navy, built by Harland & Wolff and launched on 15 December 1959. She measured 370 feet (112.78 meters) overall in length, with a beam of 41 feet (12.50 meters) and a draught of 13 feet 6 inches (4.11 meters). Powered by Y-100 machinery identical to that of the Whitby-class, she featured two Babcock & Wilcox water-tube boilers feeding steam to two geared steam turbines, rated at 30,000 shaft horsepower, enabling her to reach speeds of approximately 29.5 knots (33.9 mph). Her crew comprised around 212 officers and men. Armament-wise, HMS Berwick was equipped with a twin 4.5-inch (113 mm) Mark 6 gun mount forward, carrying 350 rounds. Originally intended to have a twin 40 mm Bofors mount aft, she was fitted with a single L/60 40 mm Bofors as a temporary measure, with plans to replace it with Seacat missile systems that were never realized. Her anti-submarine weaponry included twelve 21-inch torpedo tubes for Mark 20E Bidder homing torpedoes—though these proved ineffective and were soon removed—and two Limbo anti-submarine mortars. Her sensor suite comprised surface and air search radars (Type 293Q and Type 277), fire control systems, navigation radars, and sonar arrays (Type 174, Type 170, and Type 162). Commissioned in 1961, HMS Berwick served as leader of the 5th Frigate Squadron (1961–63) and later of the 21st Escort Squadron (1963–65). She participated in notable operations including search efforts following a 1962 aircraft carrier Hermes crash, escort duties during the Sunda Straits Crisis in 1964, and enforcing the Beira Patrol in 1966. She was re-fitted with helicopter facilities in 1967, enhancing her anti-submarine capabilities. Throughout her service, Berwick undertook extensive deployments, including a global circumnavigation from 1975 to 1976 and patrols within the UK’s expanded Exclusive Economic Zone (EEZ) from 1977. She also participated in the Silver Jubilee Fleet Review in 1977. Decommissioned and placed in reserve in 1980, her condition deteriorated, but she was reactivated during the Falklands conflict in 1982, serving in the South Atlantic. Her final years included active West Indian training cruises before being paid off in 1985. HMS Berwick was ultimately sunk as a target by a Tigerfish torpedo fired from the submarine Tireless in 1986, marking the end of her distinguished service.
