Port Belgrano Naval Base
Located near Punta Alta in the Buenos Aires Province, the Port Belgrano Naval Base (Base Naval Puerto Belgrano - BNPB) serves as the primary strategic hub for the Argentine Navy. Situated approximately 560 km south of Buenos Aires near Bahía Blanca, this massive installation spans 122 hectares (300 acres) and provides the critical infrastructure necessary for the nation's maritime defense.
The base takes its name from the brigantine General Belgrano, which sounded the waters of the area in late 1824. Today, it is the home of the Flota de Mar (Argentine Seas Fleet), concentrating the country's most significant warships and arsenals. Its strategic importance is further enhanced by its proximity to other key military sites, including the Baterías Marine camp and the Comandante Espora (BACE) naval aviation air base.

Historical Evolution
The base was designed by Italian engineer Luis Luiggi and officially opened on November 30, 1896. Originally named Puerto Militar, the facility was renamed Puerto Belgrano in 1923. Logistics were significantly improved in 1911 when the French-owned Ferrocarril Rosario y Puerto Belgrano established a broad gauge railway line connecting the base to Rosario.
Throughout the 20th century, the base evolved alongside the fleet. It hosted the Rivadavia-class battleships ARA Moreno and ARA Rivadavia during the World Wars, and later served as the dock for aircraft carriers ARA Independencia and ARA Veinticinco de Mayo during the Cold War.
In a notable diplomatic moment in April 2006, the British Royal Navy's Antarctic patrol vessel HMS Endurance entered the base for rudder repairs. This marked the first time a British Royal Navy ship had entered the facility since the conclusion of the 1982 Falklands War.
Infrastructure and Facilities
Port Belgrano is more than a military dock; it is a comprehensive community designed around the quays and drywalls proposed by Captain Félix Dufourq. The base provides a wide array of services for naval personnel and their families, including:
- Education: Public schools and six military schools at the middle and tertiary levels.
- Healthcare & Religion: A naval hospital and the "Stella Maris" Catholic parish.
- Community Services: Seven residential neighborhoods, a post office, a civil registry, and a hotel.
- Culture: A museum and the newsroom for the magazine "Gaceta Marinera".

The Centro Espacial Manuel Belgrano (CEMB)
Expanding beyond maritime operations, the base is the site of the Centro Espacial Manuel Belgrano (CEMB). This facility is designed as a launch pad for the "Tronador II," an Argentine space launch vehicle. Land for this project was ceded to CONAE (the Argentine Space Agency).
The location was specifically chosen due to the existing security measures of the Navy, the availability of large land areas, and a geographical position that is highly favorable for launches into polar orbits.
