HMS Eastbourne was a Whitby-class (Type 12) anti-submarine frigate of the Royal Navy, designed primarily for escort and patrol duties in cold waters. Laid down on 13 January 1951 at Vickers-Armstrongs' shipyard in Newcastle upon Tyne, she was launched on 29 December 1955 and completed on 9 January 1958. The vessel measured approximately 370 feet in length overall, with a waterline length of 360 feet, a beam of 41 feet, and a draught of 11 to 13 feet, depending on the location of the measurement. Equipped with the innovative Y-100 machinery, Eastbourne was powered by two Babcock & Wilcox water-tube boilers feeding steam at 550 psi and 850 °F into two geared steam turbines, which drove two large, slow-turning propellers. This machinery allowed her to reach speeds of up to 29 knots, with a range of about 4,500 nautical miles at 12 knots. Her armament included a twin 4.5-inch Mark 6 gun mount forward, with 350 rounds of ammunition, and a stabilised twin Bofors 40 mm L/60 gun mount aft for close-in defense. She was also fitted with anti-submarine weaponry, including twelve 21-inch torpedo tubes with Mark 20E Bidder homing torpedoes, though these proved ineffective against modern submarines and were later removed. Additional anti-submarine capabilities were provided by two Limbo mortars. Her electronic suite comprised surface/air search radar (Type 293Q), a height-finding radar (Type 277), fire control radar (Type 275), navigation radar (Type 974), and sonar systems (Types 174, 170, and 162). HMS Eastbourne served initially with the 3rd Training Squadron and was later loaned to the Fishery Protection Squadron, notably during the First Cod War in 1958, where she played a key role in protecting British trawlers off Iceland. She also participated in operations in the Mediterranean and served as a training ship, including leading the Dartmouth Training Squadron in 1966. In the 1970s, she replaced Rapid as a training vessel for artificer apprentices and took part in the Queen’s Silver Jubilee Fleet Review. Her later years saw her involved in the third Cod War, where she was damaged in a collision with the Icelandic vessel Baldur. Repairs revealed that she was no longer fit for active service, and she was repurposed as a harbour training ship at Rosyth Dockyard. She was de-stored and paid off in March 1984, marking the end of her operational life.
