Falklands War order of battle: Argentine naval forces

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.

Background

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.

Operation Relámpago

Operation Relámpago (Thunderbolt) ^[19] was a planned resupply mission to be carried out by the Argentine Navy between May and June using four requisitioned trawlers crewed with naval personnel. Some of the ships had been previously involved in surveillance and rescue operations, but manned by their civilian complements. The trawlers were moored with their cargoes in different inlets at Isla de los Estados, awaiting for an opportunity to cross to the Falklands, but the Argentine Navy dropped the plans just before the final British assault on Stanley. ^[20]

Falkland Islands Government ship

• ARA Forrest – armed coaster: She fought off a Sea Lynx helicopter that had put the patrol craft Islas Malvinas out of action near Kidney Island on 1 May. The aircraft came back to HMS Alacrity with serious damage from small arms fire, while Forrest was repeatedly struck by machine gun fire, without casualties. ^{[22] [23]} While at anchor in Port Howard in the night of 10 May, the ship received a stress signal from ARA Isla de los Estados when the transport was shelled and sunk by Alacrity. Forrest sailed off, but was ordered to steam back to port after being illuminated by two star shells. ^{[24] [25]} The following day she rescued two survivors of the crew of the lost ship. Later in the war, Forrest towed ARA Monsunen to Darwin, after this ship faced the attack of two British frigates and a helicopter. She uploaded ARA Monsunen's cargo and completed the supply mission to Stanley on 25 May. The vessel was involved in harbour duties until the end of the war.

Falklands Islands Company ships

Coaster Monsunen (detail)

• ARA Monsunen – armed coaster: She survived the attack of two British frigates and a helicopter west of Lively island, successfully avoiding them by running aground at Seal Cove, while defending herself with machine gun fire. Her supply mission was eventually carried out by ARA Forrest, which towed her to Darwin. Recovered by British forces on 29 May, after the battle of Goose Green.
• ARA Penelope – ketch: Spotted by ARA Bahía Buen Suceso at Speedwell Island and seized by an Argentine prize crew on 7 May. ^[26] She accomplished a logistic mission from Fox Bay to Stanley. While uploading her cargo, the ketch endured a naval bombardment by HMS Plymouth on Fox Bay's fuel depots during the first hours of 26 May. Penelope eventually reached Stanley with a cargo of fuel drums on 2 June. ^[27]

Minor vessels at Stanley harbour

• James Caird – a captured whaleboat belonging to HMS Endurance, left behind at port pending repairs, which were completed by Argentine technicians. The motor boat was prepared for a mission of sabotage with limpet mines in the Falklands Sound the first week of May, but it was aborted when the vessel had made barely 9.5 miles (15.3 km) from Port Stanley. Aside from harbour duties, the whaler also laid a telephone cable connecting the port and Cortley Ridge on 4 June. ^[28]
