Construction and trials

She was built at the Argentine AFNE Río Santiago shipyard and commissioned in 1980.[1]

Sabotage

The commissioning of the ship, whose construction began in 1973, was long delayed by an improvised limpet mine attack carried out by divers of the guerrilla organization Montoneros on 22 August 1975. The date was chosen as a retaliation for the massacre of Trelew three years before, when a number of leftist militants were executed inside Almirante Zar air base, operated by the navy. The raid was allegedly planned after Operation Frankton, a British commando attack against German shipping in Bordeaux during WWII. Indeed, the attack involved the use of a folding boat, frogmen and 375 lb of explosives. Santísima Trinidad hull and electronics suffered severe damage. The completion's works were suspended for another year as a result of the attack.[2][3]

Commissioning

The Argentine Navy upgraded the Type 42 warships by enhancing their offensive capabilities with MM-38 Exocet missiles.[4] The original design's boat decks were replaced by special decks to install the missiles around the funnel, but the launchers were apparently never mounted on Santisima Trinidad.[5][6] In November 1981, she made her maiden voyage to Britain, where the destroyer carried out her first sea trials, and her crew was trained in the operation and launching of Sea Dart missiles.[7]

Operational History

Falklands War

Argentine Landings

She was the leading ship of the Argentine landings on the Falklands, on 2 April 1982. Both the Navy and the Army top commanders of the operation were on board.[8] A team of 84 amphibious commandos and 8 tactical divers landed at Mullet Creek at 00:00 A.M. on 21 Gemini boats lowered from her deck.[9] The wireless message asking the surrender of the British Governor and the Marines detachement was also radioed from the destroyer.[10]

Sea Harrier incident

During the remainder of the Falklands War, along with her sister ship ARA Hercules, the unit served as the main escort to the aircraft carrier ARA Veinticinco de Mayo.[11] At first, Hercules would operate independently along with a group of older destroyers, but the development of mechanical problems on her twin ship forced the Argentine commander to merge the two Type-42 destroyers into one escorting force. The carrier naval group was known as Grupo de Tareas 79.1 (Task force 79.1), intended to search for and engage its British counterpart from waters north of the Falklands.[12] Santísima Trinidad had the command and control of the group's air defence.[6] On the late hours of 1 May, the carrier launched a number of S-2 Tracker surveillance aircraft, with the mission of finding the British Task Group. One of the Trackers crew radioed that they were being chased by an unknown jet while returning to the Veinticinco de Mayo. Shortly after midnight, the Santísima Trinidad was ordered to switch her Type 965 radar on and track the unidentified contact. She then locked up a Sea Harrier with her Type 909 fire-control radar, followed afterwards by her sister ARA Hercules. The British aircraft, Sea Harrier nº XZ451 piloted by Flt. Lt. Ian Mortimer, was fended off by the threat of the Sea Dart, but not before spotting the area of deployment of the Argentine Fleet.[13][6] After realising that the enemy was not engaged in a major amphibious operation as supposed, which made any attempt of the Argentine against the British carriers extremely dangerous, the Argentine commander, Admiral Allara, decided to withdraw his forces to shallow waters close to the coast.[14]

Withdrawal

The destroyer lost her Sea Lynx helicopter on 4 May, as the Argentine fleet was redeploying, when the aircraft hit her flying deck.[15] She spent the next days in drydock to repair the mechanical problems which reduced her speed during the operations of May 1.[12] Right to the end of the conflict, she was engaged in patrol duties off Patagonia. Once the cease of hostilities was declared, Santísima Trinidad escorted into Puerto Madryn the British transport Canberra, with about 3,000 Argentine prisoners on board.[16]

After the war

After the war the British weapons and supplies embargo on Argentina made the purchase of spare parts impossible[17] even in the black market. The Argentine Minister of Defense was even thinking of selling the destroyers.[18] As a consequence, the Navy was forced to place Santísima Trinidad in reserve as a parts supplier for Hércules.[19] From 2 March until 15 March 1987 she took part of Operation Grifo, the Argentine response to Operation Fire-Focus, the largest British military exercise around the Falklands since 1982.[20] Her last Sea Dart missile test launch was conducted on 27 November 1987 against an Argentine-built drone.[21][22] Santísima Trinidad´s last voyage took place in 1989. She has not sailed since.[22]

Fate

At present, the Santisima Trinidad is listed as "in reserve awaiting overhaul", however, it is expected that the Navy will formally decommission her. There are projects in the Argentine Congress calling for Santisima Trinidad to be converted into a museum ship.[19][23]
