On 18 November 1954 the Antarctic Naval Task Force, commanded by Ship-of-the-Line Captain Alicio E. Ogara, sailed from Buenos Aires with the objective of setting up a base on the Filchner Ice Shelf that would serve as a launch point for expeditions to the South Pole.

[1] On 2 January 1955 the expedition sailed up to the southernmost point of the Weddell Sea at 78° 01' S. At the time it set a new world record for the highest austral latitude ever reached by boat.

[1] Belgrano I was shut down after 25 years of continuous service, due to the fast deterioration of the ice barrier it was sitting on; new, often hidden cracks and crevices endangered the on-duty personnel and material.

[2] On 26 January 1988 a helicopter from Almirante Irízar confirmed that a tabular iceberg about 100 km (62 mi) long containing had split from the ice shelf.

These passages provided a safer means of walking across buildings without exposure to the exterior freezing temperatures and whipping winds; they were also used as temporary deposits.

[1] Being placed in the auroral zone, Belgrano was ideal for studies of the upper atmosphere, characterized by constant magnetic and ionospheric disturbances.

A tower equipped with all-sky cameras photographed the whole celestial hemisphere every minute in order to compose a continuous record of aurorae evolution.
