Armed Forces of the Argentine Republic

After the Revolución Libertadora coup that deposed president Juan Domingo Perón in 1955, the armed forces split into opposing sectors named Azules y colorados ("Blues and Reds"). The fight would end in 1963 with military clashes and the defeat of the reds who were opposed to Perón.

In 1965, the Argentine military conducted land military maneuvers on Antarctica under then-Colonel Jorge E. Leal. Nicknamed Operación 90, this was undertaken ten years before the Antarctic Treaty came into being and was conducted to cement Argentina's claims to a portion of those territories (still claimed as Argentine Antarctica).

In 1975 the armed forces started a massive operation in the Tucumán Province to crush the ERP (Ejército Revolucionario del Pueblo or People's Revolutionary Army) guevarist guerrilla group which attempted to create a "revolutionary foco in this remote and mountainous province, in the north-west of Argentina."

The last military dictatorship, the National Reorganization Process, lasted from 1976 to 1983. As Isabel Perón was unable to defeat the terrorist organizations of Montoneros and ERP, the military took power during the 1976 Argentine coup d'état and exterminated the violent communist guerrillas by random detentions, torture or death. The current government of Cristina Fernández de Kirchner that sympathizes with Perón, antagonized the Armed Forces with the justification of the past junta and limits the powers of the current armed forced to avoid state terrorism of the past.

During much of the 19th and the 20th century, relations between neighbour Chile chilled due to disputes over Patagonia, though in recent years relations have improved dramatically.

On 2 April 1982, Argentine forces invaded the British overseas territory of the Falkland Islands; this was followed by the invasion of South Georgia islands. Britain sent a big task force to recover the islands. Argentina incurred many losses and surrendered on 14 June. The political effects of the surrender were strong, leading to large protests against the dictatorship, which hastened its downfall.

The democratic government of Raúl Alfonsín that took office in 1983 prosecuted the 1970s crimes and made the unprecedented (and only Latin American example) Trial of the Juntas and soon the Army was rocked by uprisings and internal infighting. Far-right sectors of the Army rebelled in the Carapintadas (painted faces) movement. To contain the rebellions, Alfonsín promoted the Full stop law and the Law of due obedience. The following president, Carlos Menem, gave the presidential pardon to the military found guilty in the Trial of the Juntas. It would not be until 1990, when the last military uprising in Argentine history was crushed, that the political conflict within the Army finally subsided.

In January 1989, during the subversive attack on La Tablada, the Army used white phosphorus in a violation of the Geneva Convention (according to a document presented by the human rights commission of the United Nations on January 12, 2001).[5]

Argentina was the only Latin American country to participate in the 1991 Gulf War sending a destroyer and a corvette in first term and a supply ship and another corvette later to participate on the United Nations blockade and sea control effort of the gulf. The success of "Operación Alfil" (English: "Operation Bishop") as it was known, with more than 700 interceptions and 25,000 nautical miles (46,000 km) sailed on the operations theatre helped to overcome the so-called "Malvinas syndrome".

From 1990 to 1992, the Baradero-class patrol boats were deployed under UN mandate ONUCA to the Gulf of Fonseca in Central America. In 1994, the three Drummond-class corvettes participated on Operation Uphold Democracy in Haiti.

Also, in the 1990s, Argentine Armed Forces began a close defense cooperation and friendship policy with neighbors Brazil and Chile, with emphasis on fulfillment of United Nations mandates.

The Argentine military have been reduced both in number and budget, but became more professional, especially after conscription was abolished by president Menem. The British embargo due to the Falklands War (Spanish: Guerra de las Malvinas) was officially eliminated and Argentina was granted Major Non-NATO ally status by United States President Bill Clinton.[6]

The modern Argentine Armed Forces are committed to international peacekeeping under United Nations mandates, humanitarian aid on emergencies relief and support the country's continuous presence at Antarctica.

Democratic governments since 1983 streamlined the military budget and did not approve any large scale equipment purchases. Argentina military spending is one of the lowest of South America[7][8] and as of 2010, its 0.9% of GDP only exceeds Suriname[9] Within the defence budget itself funding for training and even basic maintenance was significantly cut, a factor contributing to the accidental loss of the Argentine submarine San Juan in 2017. The result has been a steady erosion of Argentine military capabilities, with some arguing that Argentina had, by the end of the 2010s, ceased to be a capable military power.[10]

The small-scale capability modernization that Argentina has attempted has been actively opposed by the United Kingdom. In 2019 the Argentine Air Force and government selected the Korean KAI FA-50 as its interim fighter to replace its aging Falklands-vintage aircraft. However, the deal was cancelled in early 2020 leaving the Air Force without a fighter replacement. British intervention was apparently a key factor in the cancellation with Britain stopping the export of the aircraft incorporating various British components.[11] In October 2020, Korea Aerospace Industries (KAI) confirmed that since major components of the aircraft were supplied by the U.K., the aircraft could not be exported to Argentina. Britain similarly blocked the potential sale of Brazilian license-built Saab Gripen aircraft to Argentina given avionics that were of British origin.[12]

In 2003, for the first time, the Argentine Navy (classified as a major non-NATO ally) interoperated with a United States Navy battlegroup when destroyer ARA Sarandí (D-13) joined the USS Enterprise Carrier Strike Group and Destroyer Squadron 18 as a part of Exercise Solid Step during their tour in the Mediterranean Sea.

On June 12, 2006, President Néstor Kirchner brought into force the Defense Law, which had been passed in 1988 as a means to modernize the doctrine of the armed forces and define their role. The law states that the armed forces will only be used against foreign aggression, and reduces the powers of the heads of the armed services, centralizing whole operational and acquisitions decisions under the authority of the Armed Forces Joint General Staff (Spanish: Estado Mayor Conjunto de las Fuerzas Armadas – EMC ) emphasizing Jointness.

In 2007, an agreement for cooperation in peace operations was signed with France.[13]

A combined Argentinian-Chilean force for future United Nations Mandates was created.[14] Named Cruz del Sur (English: Southern Cross), the new force began assembly in 2008 with its headquarters alternating between the two countries each year.[15]

In 2009, UNASUR, the South American countries union, created the CDS ( Spanish: Consejo de Defensa Sudamericano (South American Defence council) in order to promote cooperation and transparency between their armed forces[16]

As of 2011, they perform with Chile the PARACACH (Patrulla de Rescate Antártica Combinada Argentina-Chile, Argentine Chilean Antarctic combined search and rescue patrol) with support from the German Space Agency which provided satellite imagery[17]
