The base is used by Argentine Navy ships participating in each year's Antarctic Campaign for maintenance and resupply.

The geographical area of its jurisdiction includes the province of Santa Cruz, the Big Island of Tierra del Fuego and the island of the States, and the southern maritime spaces that reach the 60º South parallel.
