HMS Barrosa (D68) was a Battle-class fleet destroyer of the Royal Navy, constructed as part of the 1943 construction programme designed to address the inadequacies of earlier destroyers in anti-aircraft defense during World War II. Built by John Brown & Company on the Clydebank shipyard, she was laid down on 28 December 1943, launched on 17 January 1945, and completed on 14 February 1947. Measuring 379 feet in length overall, with a beam of 40 feet 6 inches and a draught of 12 feet 9 inches (normal), HMS Barrosa displaced approximately 2,550 long tons at standard load and up to 3,420 long tons at full load. Her propulsion system comprised two Admiralty 3-drum boilers feeding Parsons single-reduction geared turbines, rated at 50,000 shp, which propelled her to a top speed of 34 knots. Her armament included two twin 4.5-inch Mark IV gun mounts capable of high-angle fire, a single 4.5-inch gun aft, and a comprehensive anti-aircraft suite featuring eight Bofors 40 mm guns, with stabilized STAAG mounts and additional single mounts. She was equipped with two quintuple 21-inch torpedo tubes and a Squid anti-submarine mortar. Initially joining the 4th Destroyer Flotilla of the Home Fleet, her early service was curtailed by manpower shortages, leading to periods in reserve. She returned to active duty in 1948, participating in exercises and port visits, and was involved in collision incidents, notably with the oiler Black Ranger in 1949 and HMS Corunna in 1959. Throughout the 1950s and 1960s, Barrosa served predominantly in the Mediterranean and Far East, undertaking patrols against arms smuggling, pirates, and during the Indonesia–Malaysia confrontation. She was adapted into a radar picket ship with missile and radar enhancements in the early 1960s. Her notable operations included participation in the Coronation Fleet Review of 1953, involvement in the Suez Crisis, and efforts to contain the Torrey Canyon oil spill in 1967. She also played a role in the Beira Patrol and assisted the Royal Fleet Auxiliary ship Lyness in 1968. Decommissioned in December 1968, HMS Barrosa was eventually used as a storage hulk before being scrapped at Blyth in 1978. Her service spanned over two decades, reflecting the evolving strategic needs of the Royal Navy during the Cold War era.
