ARA General Belgrano

ARA General Belgrano was a light cruiser of the Argentine Navy, originally built for the United States Navy as USS Phoenix (CL-46). It was the only ship sunk by a nuclear-powered submarine during wartime, torpedoed by HMS ''Conqueror'' during the Falklands War. The sinking, which resulted in the loss of 323 lives, remains one of the most controversial actions of the conflict and a pivotal moment in modern naval warfare.

History and acquisition

The vessel was constructed as the ''Brooklyn''-class light cruiser USS Phoenix (CL-46) by the New York Shipbuilding Corporation in Camden, New Jersey. It served extensively in the Pacific Theater of Operations during World War II, surviving the attack on Pearl Harbor and earning nine battle stars. Following the war, it was decommissioned from United States Navy service in 1946 and placed in reserve. In 1951, the ship was sold to Argentina under the Mutual Defense Assistance Act, joining the Argentine Navy and renamed ARA *17 de Octubre* in honor of the date marking Juan Perón's rise to power. After Perón's overthrow in 1955, the cruiser was renamed for Manuel Belgrano, a founding father of Argentina. It underwent a significant modernization in the late 1960s at the Puerto Belgrano Naval Base, which included the addition of Aérospatiale Exocet anti-ship missile launchers and updated radar systems.

Sinking in the Falklands War

At the outbreak of the Falklands War in April 1982, the cruiser, as part of the Argentine Navy's Task Force 79, was deployed to patrol the waters south of the Falkland Islands. On 2 May 1982, while sailing just outside the Total Exclusion Zone declared by the United Kingdom, it was tracked by the Royal Navy submarine HMS ''Conqueror''. Acting on orders from the British War Cabinet in London, Conqueror fired three Mark 8 torpedoes, two of which struck the cruiser's port side. The explosions caused catastrophic damage, severing electrical power and preventing a distress call. The ship listed rapidly and sank approximately 45 minutes after being hit. Despite rescue efforts by other vessels like ARA ''Gurruchaga'' and ARA ''Bahía Paraíso'', 323 of the 1,093 men aboard perished, marking the single greatest loss of life in the war.

Aftermath and legacy

The sinking provoked immediate international controversy and diplomatic fallout. The Government of Argentina condemned the attack as a "war crime," arguing the ship was outside the declared exclusion zone and sailing away from the conflict area. The Government of the United Kingdom, led by Prime Minister Margaret Thatcher, defended the action as a necessary measure of self-defense under Article 51 of the United Nations Charter, citing the threat posed by the cruiser's armament and its supporting Task Force 79. The event hardened Argentine resolve but also effectively neutralized the surface threat of the Argentine Navy, which largely withdrew to port for the remainder of the conflict. In Argentina, the date is commemorated annually, and the victims are honored as national heroes. The action remains a subject of intense historical and legal debate concerning the rules of engagement and maritime exclusion zones in modern warfare.

Wreck site

The wreck of the cruiser lies approximately 230 nautical miles southeast of Puerto Deseado in the South Atlantic Ocean, at a depth of over 4,200 meters (13,800 feet) within the Argentine continental shelf. The site is designated a war grave under Argentine law and is protected from unauthorized disturbance. In 2003, a remote-operated vehicle survey conducted by the National Geographic Society in collaboration with the Argentine Navy located and filmed the largely intact wreck, which rests upright on the seabed. The images confirmed the severe damage from the torpedo hits and provided closure for many families of the victims. The site is considered a hallowed memorial to those lost.
