This article describes the composition and actions of the Argentine naval forces in the Falklands War (Spanish language: Guerra de las Malvinas ). For a list of naval forces from the United Kingdom, see British naval forces in the Falklands War.


The Argentine Navy (ARA), particularly its commander-in-chief and Junta member, Admiral Jorge Anaya, was the main architect and supporter of a military solution to resolve the long-standing claim of sovereignty over the islands. His first attempt came in 1976 when he was the Navy Chief's Operations of the recently established Military dictatorship but General Videla and Admiral Massera were more busy disappearing people at that time.[1] By 1982 the country was already in the midst of a devastating economic crisis and large-scale civil unrest against the repressive government and Anaya, now a member of the ruling Junta, ordered Operation Rosario to be brought forward to 2 April, after a group of Argentina military infiltrated a group of Argentine scrap metal merchants and raised the Argentine flag at South Georgia 19 March.

General Galtieri, acting president, agreed in his intention to mount a quick, symbolic occupation, followed rapidly by a withdrawal, leaving only a small garrison to support the new military governor and force the UK to begin talks on the long-delayed sovereignty claim. On 2 April an amphibious landing was made at Stanley and on 3 April Argentine marines used helicopters to take over the Georgias. Whilst the military junta was redeploying the assault units back to their home bases they found the British responded with a large-scale mobilisation to organise a naval task force and ground forces to retake the islands by force. The war could not have happened at a worse time for the Argentines. They were expecting new destroyers, frigates and submarines being built in West Germany and their shipment of French Super Etendards and Exocets were not yet complete. On the other hand, the Royal Navy was in middle of great cutbacks that would have eliminated its force of aircraft carriers and amphibious forces in the coming months.

Argentine Navy

Operation Rosario (2 April)

Vice Admiral Juan José Lombardo
Ships that only participated in the initial invasion, 2 April:

Task Group 20

Commander José Sarcona

Task Group 40

Rear Admiral Jorge Allara

South Georgia (3 April)

  • ARA Guerrico (P-32) - A Drummond -class (D'Estienne d'Orves class) corvette. (†1)
  • ARA Bahia Paraiso Antarctic Survey ship. A polar transport, later deployed as hospital ship off Stanley. Bahía Paraíso transported Argentine forces from Corbeta Uruguay base to South Georgia in the events preceding the Falklands War. The Bahía Paraíso sank in Antarctica on 30 January 1989 after running aground near Janus and DeLaca Island.

Falklands Theatre of Operations [Teatro de Operaciones Malvinas] (2 April-14 June)

  • ARA Alférez Sobral - a Sotoyomo class patrol vessel, formerly USS Salish (ATA-187), damaged by Sea Skua missiles fired by Westland Lynx HAS.Mk.2/3 helicopters from HMS Glasgow and HMS Coventry. (†8)
  • ARA Comodoro Somellera, a Sotoyomo class patrol vessel, formerly USS Catawba ATA-210. During the war the British claimed to have sunk the Comodoro Somellera with Sea Skua, this claim was subsequently dropped when the British evaluated wartime reports after the war. The ship continued to serve in the Argentine navy until 1998 when she sank in the port of Ushuaia during a storm following a collision with ARA Suboficial Castillo (A-6) .[2][3][4]
  • ARA Isla de los Estados - A transport ship sunk by HMS Alacrity in Falkland Sound. (†22)
  • ARA Bahía Buen Suceso - A transport ship, she was moved from Stanley to the Falklands Sound on 29 April. During the trip, the ship spotted the schooner Penelope, property of the FIC, which was taken over by an Argentine Prize crew the following day. While at anchor at Fox Bay, the transport ran aground in a storm and was later damaged by 30 mm ADEN cannon fire from BAe Sea Harrier FRS.Mk.1s. The British eventually captured the hull after the war and sunk her in high seas. The Bahía Buen Suceso transported Constantino Davidoff's party to South Georgia precipitating the Falklands War.
