FALKLANDS SPY PLOT EXPOSED: Argie submarine was snooping on UK islands when it vanished
All 44 people onboard the ARA San Juan are believed to have perished on the boat which disappeared on November 15 last year.
Argentine President Mauricio Macri and other officials have always said the navy vessel had been carrying out training exercises when it disappeared.
The government's Chief of Staff, Marcos Pena, told Members of Parliament the submarine ARA San Juan's primary objective was to "locate, identify and register with photographs / videos logistic carrier vessels, oil tankers and investigation ships under other flags".
However, Mr Pena then added: "As secondary objectives of this activity, they established vessels and aircraft that operate out of the Falkand Islands."
Mr Pena also revealed a list of the vessels and aircraft the submarine had identified, which included RAF planes and aircraft from the Falkland Islands Government.
This shocking revelation comes four months after the submarine disappeared off the coast of Argentina.
Ships from the Argentinian Navy are still looking for the presumed sunken submarine which suddenly stopped all communication on 15th November 2017.
Officials have abandoned hopes of rescuing any of the 44 crew members alive.

Within hours of ARA San Juan's last transmission, reports describe an acoustic anomaly compatible with an explosion detected in the vicinity of the vessel's last known location.
The Falkland Islands is a British Overseas Territory 300 miles (483 km) off the coast of South America.
Argentina claim the islands as their own, claiming they acquired the territory from Spain when it achieved independence in 1816.
However, the British founded a port there in 1766, just two years after the French founded one in 1764, when the island was uninhabited.
In 1766, the French surrendered its claim to the Falklands to Spain, and the British and Spanish coexisted on the island until 1774, when the British left, leaving a plaque claiming the islands for George III.
The British returned in 1832 and reasserted their rule there.
In 1840, the islands became a Crown colony with Scottish settlers.
In 1982, Argentina invaded the Falklands, which prompted Prime Minister Margaret Thatcher to declare a war zone of 200 miles around the islands. The British subsequently retook the islands.
