This article describes the composition and actions of the Argentine naval forces in the Falklands War. 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. 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 Étendards and Exocets were not yet complete.

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

  • ARA Alferez Sobral - a Sotoyomo-class patrol vessel 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. During the war the British claimed to have sunk Comodoro Somellera with a 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.[1][2][3]
  • ARA Isla de los Estados - transport ship sunk by HMS Alacrity in Falkland Sound. (†22)
  • ARA Bahía Buen Suceso - a transport ship, Bahía Buen Suceso transported Constantino Davidoff's party to South Georgia precipitating the Falklands War. 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 sank her in high seas.
