In April 2006, the Royal Navy's Antarctic patrol vessel HMS Endurance entered Puerto Belgrano for repairs after damaging its rudder while in Antarctica in February.

It was the first time since the end of the 1982 Falklands War (Spanish: Guerra de las Malvinas) that a British Royal Navy ship had entered the Argentine naval base.

The base contains a naval hospital, specialized workshops, six middle and tertiary level military schools, a banking headquarters and seven residential neighborhoods for naval personnel, public schools, a printing press, the newsroom of the magazine "Gaceta Marinera", a bank headquarters, the "Stella Maris" Catholic parish, a civil registry, post office, a museum, seven residential neighborhoods for naval personnel, a hotel, among other facilities.

All of them surround the quays and drywalls that were proposed by the ship's captain Félix Dufourq, who carried out many of the studies aimed at finding the most suitable place for the construction of the naval facilities.

A launch pad is planned Argentine space launch vehicle "Tronador II", named Centro Espacial Manuel Belgrano (CEMB) at 38°57′46″S 61°42′54″W / 38.9628°S 61.715°W / -38.9628; -61.715 (Centro Espacial Manuel Belgrano (CEMB)).
