The ARA Santísima Trinidad was a notable Type 42 destroyer of the Argentine Navy, commissioned in October 1980 and built at the Argentine AFNE Río Santiago shipyard with assistance from UK engineers and technicians. As the only ship of her class to be constructed outside Britain, she was an advanced warship with a length of approximately 134 meters and a displacement that suited her role as a flagship and escort vessel. The vessel’s design included facilities for missile armament, with modifications made to accommodate MM-38 Exocet missiles, although the launchers were apparently never installed on her. Her construction was delayed by an attack from guerrilla divers of the Montoneros on 22 August 1975, who attempted to place a limpet mine on her hull as retaliation for the Trelew massacre. The attack inflicted severe damage to her bottom and electronics, suspending construction for a year. Despite this setback, Santísima Trinidad completed her sea trials in Britain in April 1981, where her crew trained in Sea Dart missile operations before returning to Argentina in December. The destroyer played a pivotal role in the Falklands War, leading the Argentine landings at Mullet Creek on 2 April 1982, with high-ranking officers aboard. During the conflict, she served as the principal escort for the aircraft carrier Veinticinco de Mayo, commanding the group's air defense and engaging in key combat operations, including tracking British aircraft and providing radar coverage. She also participated in patrols off Patagonia and contributed to electronic warfare by jamming enemy frequencies during the attack on Bluff Cove. Post-war, Santísima Trinidad was placed in reserve due to the difficulty in obtaining spare parts after the British embargo. She participated in operations like Operation Grifo in 1987 and conducted her final voyage in 1989. By 2004, she was listed as awaiting overhaul, but her condition deteriorated over time. In 2013, she sank at her moorings following flooding caused by a broken valve. Efforts to refloat her began in 2014, and she was temporarily considered for preservation as a museum ship, though this plan was later abandoned. Despite legal protections for her historical significance, photos from 2025 indicate she is being scrapped.
